Nobody grows up dreaming of becoming a medical dosimetrist or a corrosion engineer. But these are the kinds of jobs quietly paying six figures while everyone else chases the obvious titles.
The pattern is consistent: the highest-paying work isn't always the most visible. Some of it happens inside operating rooms, cleanrooms, courtrooms, and power plants, doing the technical, regulated, hands-on work that keeps hospitals, factories, and legal systems running. You won't see these roles advertised at a career fair, but employers are actively struggling to fill them.
What ties them together is licensing, specialized training, safety regulation, and physical systems that can't be automated away. In short: jobs that are hard to learn and even harder to replace. That's exactly why they pay what they do.
Here are 18 of them, what they actually pay, and what it takes to get one.
Medical dosimetrist
A medical dosimetrist helps plan radiation treatment for cancer patients. They work with radiation oncologists and medical physicists to figure out how to aim radiation at a tumor while protecting healthy tissue as much as possible. It is part math, part anatomy, part patient safety, and it is far more specific than a general health care job.
Median pay is about $138,110 per year. Most people enter after training in radiation therapy, physics, or a related health field, then complete a dosimetry program and certification. Hospitals and cancer centers need this work because cancer care is planned down to tiny details, and a rushed or sloppy plan can hurt a real person.
Cardiovascular perfusionist
A cardiovascular perfusionist runs the heart-lung machine during open-heart surgery. When a patient’s heart needs to be stopped for surgery, this person keeps blood moving and oxygen flowing. They also may help with ECMO, a life-support system used for very sick heart and lung patients.
Average pay is about $158,756 per year. You usually need a bachelor’s degree, a specialized perfusion program, clinical training, and board certification. This is not a job people stumble into. It lives inside operating rooms, transplant programs, cardiac units, and major hospitals. Demand stays strong because surgery teams need a trained human watching the machine, the patient, and the numbers in real time.
Medical physicist
A medical physicist makes sure radiation and imaging equipment is safe, accurate, and doing what doctors think it is doing. In cancer care, they check treatment machines, review radiation plans, and help solve technical problems before a patient is treated. In imaging, they work with scanners, safety rules, dose limits, and quality checks.
Average pay is about $199,889 per year. This job usually takes graduate-level physics training, residency-style clinical experience, and board certification for many roles. You will find medical physicists in cancer centers, hospitals, imaging companies, and equipment firms. The job is secure because health systems cannot just “wing it” with radiation safety. Someone qualified has to sign off.
Pathologists' assistant
A pathologists’ assistant works behind the scenes in surgical pathology. They examine tissue removed during surgery, describe what they see, prepare samples, and help pathologists diagnose disease. It is hands-on lab work with organs, tumors, biopsies, and specimens that can change a patient’s treatment plan.
After a few years, pay often reaches $100,000 to $104,999, with higher bands for more experienced workers. Most people need a master’s-level pathologists’ assistant program and certification. Hospitals, academic medical centers, private labs, and forensic settings hire for this role. It is obscure because patients rarely meet the person doing the work, but the health system relies on accurate tissue handling every day.
Certified anesthesiologist assistant
A certified anesthesiologist assistant works on anesthesia care teams under physician anesthesiologists. They help evaluate patients, place monitors, manage airways, give anesthesia medicines, and watch patients closely during surgery. The job is intense because minutes matter when someone is under anesthesia.
Average pay is about $253,487 per year. You need a strong science background, a master’s-level anesthesiologist assistant program, national certification, and authorization to practice where the role is recognized. Hospitals, surgery centers, and specialty practices hire them. It is a narrow field, but demand is supported by surgery volume, anesthesia staffing pressure, and the fact that patient care in an operating room still needs trained eyes and hands.
Radiation safety officer
A radiation safety officer is the person responsible for making sure radioactive materials and radiation-producing equipment are used safely. They write safety procedures, train staff, monitor exposure, handle audits, and deal with regulators. The work can show up in hospitals, research labs, nuclear medicine, manufacturing, and energy.
Average pay is about $101,646 per year. Many people come from health physics, nuclear medicine, medical physics, engineering, or radiation therapy. This job is not glamorous, but it is important. Facilities using radiation cannot just skip safety oversight because it is regulated, documented, and tied to worker and public health.
Nuclear criticality safety engineer
A nuclear criticality safety engineer studies how radioactive material is stored, moved, and handled so it does not accidentally start an uncontrolled chain reaction. That sounds like a movie plot, but it is a real safety job in nuclear fuel, research, cleanup, defense, and advanced energy work.
Average pay is about $128,911 per year. Most people need a nuclear engineering, physics, or related engineering background, plus deep on-the-job training. The field is small, which is part of why it pays well. It is also built around rules, reviews, calculations, and human responsibility. If a facility handles fissile material, someone has to know exactly what can go wrong.
Corrosion engineer
A corrosion engineer figures out why metal breaks down and how to stop it. That can mean pipelines, bridges, ships, tanks, water systems, refineries, wind farms, or manufacturing plants. It is the kind of job no one thinks about until something leaks, cracks, collapses, or costs millions to repair.
A level-two corrosion engineer averages about $112,543 per year. Most people start with materials, chemical, mechanical, or civil engineering, then add corrosion-specific training and certifications. Demand is steady because infrastructure ages, energy systems need inspection, and companies would rather prevent failure than explain one later. This work often mixes field visits, lab testing, reports, and practical problem-solving.
Cryogenic engineer
A cryogenic engineer works with systems that run at extremely low temperatures. That can include liquid nitrogen, liquid helium, superconducting magnets, space equipment, medical imaging, quantum computing hardware, and specialty manufacturing. It is a weird corner of engineering where ordinary materials can behave in strange ways.
Average pay is about $104,528 per year. A mechanical, chemical, aerospace, or physics-heavy engineering background is common. Employers may include research labs, medical equipment companies, aerospace firms, chipmakers, and advanced computing companies. This job is hard to automate because it deals with physical systems, safety risks, testing, failure analysis, and real equipment that has to work outside normal conditions.
Lithography engineer
A lithography engineer helps create the tiny patterns used to make semiconductor chips. They work with light, chemicals, masks, wafers, cleanrooms, and machines that cost huge sums of money. If a pattern is off, the chip may fail. That makes this a high-pressure, high-skill job most people have never heard of.
Average pay is about $119,659 per year. A background in electrical engineering, chemical engineering, materials science, physics, or a related field is common. Chipmakers, equipment vendors, research labs, and advanced manufacturing plants hire for this work. Demand is helped by the need for chips in cars, phones, medical devices, defense systems, and data centers. The work happens where real tools, wafers, and process problems meet.
Signal integrity engineer
A signal integrity engineer makes sure electronic signals move cleanly through circuit boards, cables, chips, and devices. When electronics get faster, smaller, and more powerful, signals can interfere with each other. This person finds and fixes those problems before a product becomes unreliable.
Average pay is about $144,102 per year. Most people come from electrical engineering and learn high-speed design, simulation tools, lab testing, and board-level troubleshooting. Employers include chip companies, aerospace firms, medical device makers, telecom companies, and hardware startups. The job has staying power because every connected device still has to obey physics, even when the product looks sleek on the outside.
Battery systems engineer
A battery systems engineer works on the packs and controls that make batteries safe, useful, and long-lasting. They deal with charging, heat, failure testing, battery management systems, and how cells behave under stress. The job can touch electric vehicles, grid storage, medical devices, consumer electronics, and industrial equipment.
Average pay is about $167,435 per year. Mechanical, electrical, chemical, or systems engineering can all lead into this field. Many workers build experience through test labs, power electronics, automotive programs, or energy storage projects. Demand is likely to stay strong because batteries are moving into more parts of daily life, and safety failures are expensive. Someone has to test the pack before it ends up in your car, building, or device.
Human factors engineer
A human factors engineer studies how real people use products, systems, tools, and controls. They look for design mistakes that cause confusion, injuries, medical errors, crashes, or wasted time. This job shows up in medical devices, aviation, software, cars, defense, manufacturing, and workplace safety.
Average pay is about $105,373 per year. People often enter through psychology, engineering, ergonomics, design research, or industrial engineering. The work may include user testing, risk analysis, interviews, task studies, and design reviews. It stays useful because people do not behave like perfect instruction manuals. Companies need someone who can spot where a tired nurse, driver, mechanic, or customer might make a dangerous mistake.
Bioinformatics scientist
A bioinformatics scientist uses data and code to answer biology questions. They may analyze DNA, cancer mutations, drug targets, infectious disease patterns, or clinical research results. It is not plain data work, because you also need to understand the science behind the numbers.
Average pay is about $116,147 per year. Many people have a graduate degree in bioinformatics, biology, statistics, computer science, or a related field. Employers include drug companies, hospitals, genetic testing labs, universities, biotech firms, and public health groups. The field keeps growing because modern medicine creates enormous amounts of biological data, and someone has to turn that data into decisions researchers and doctors can use.
Pharmacovigilance scientist
A pharmacovigilance scientist studies drug safety after medicines reach patients. They review side effects, safety reports, clinical data, and patterns that might show a drug risk. The job is part science, part regulation, part detective work, and part paperwork that really matters.
Average pay is about $138,544 per year. Common backgrounds include pharmacy, nursing, life sciences, medicine, public health, or clinical research. Drug companies, contract research firms, device companies, and regulatory teams hire for this role. Demand is steady because every approved medicine still has to be monitored. Software can sort reports, but trained people still have to judge seriousness, patterns, and what needs action.
Flavorist
A flavorist creates and adjusts flavors for foods, drinks, candy, supplements, and other consumer products. They may work on making a strawberry flavor taste more real, a protein drink less bitter, or a low-sugar product less flat. It is chemistry, smell, taste, memory, and customer testing all mixed together.
Average pay is about $102,164 per year. Many flavorists start in chemistry, food science, or lab technician roles, then train for years under senior flavorists. Food companies, flavor houses, beverage brands, and ingredient makers hire them. The job is obscure because the work is hidden inside labels and recipes, but companies keep paying for it because taste can make or break a product.
E-discovery manager
An e-discovery manager helps legal teams find, preserve, review, and organize electronic records for lawsuits and investigations. That can include emails, chats, documents, phone data, databases, and cloud files. The job sits where law, technology, privacy, and deadlines all collide.
Average pay is about $140,390 per year. People often come from paralegal work, litigation support, legal technology, records management, or IT. Law firms, corporations, consulting firms, and government agencies hire for it. Demand stays steady because lawsuits and investigations are not getting simpler, and digital evidence keeps growing. The work needs judgment, confidentiality, and a calm head when attorneys need answers fast.
Patent agent
A patent agent helps inventors and companies protect new inventions. They draft patent applications, respond to examiners, search technical records, and translate complicated science or engineering into legal claims. Unlike patent attorneys, patent agents do not have to be lawyers, but they do need the right technical background and must pass the patent bar.
Average pay is about $108,111 per year. Many patent agents have degrees in engineering, computer science, chemistry, biology, or physics. They work for law firms, tech companies, universities, drug companies, and research-heavy businesses. This job is likely to stay useful because inventions, disputes, and intellectual property filings keep moving, and the work needs both technical fluency and careful legal judgment.
