B2 Engineer Job Description
Explore the B2 Engineer role in defence aviation. Discover day-to-day avionics and electrical responsibilities, Part-66 B2 licence routes and CV must-haves.
Thinking about a career as a B2 Engineer? This highly specialised engineering role focuses on the electrical, avionics, and electronic systems that keep military aircraft safe, operational, and mission‑ready. Here, we’ll walk through what a B2 Engineer does day‑to‑day, how to become one, what to put on your CV, and the related roles worth considering across defence aviation and engineering support.
What Is a B2 Engineer?
A B2 Engineer, also known as a B2 Licensed Engineer or B2 Certifying Engineer, is responsible for maintaining, fault‑finding, repairing, testing and certifying aircraft avionics and electrical systems. In the aerospace and defence sector, the work is centred around military and government aircraft, including rotary platforms, fast‑jets, multi‑role transports, trainers, helicopters and mission‑specific aircraft.
Defence B2 Engineers work with mission systems, secure communications, sensors, navigation equipment, surveillance systems, defensive aids, avionics suites, cockpit instrumentation, power distribution, and electronic warfare technologies. The work is highly regulated, security‑sensitive, and often supports operational readiness, requiring a high level of engineering ability, as well as DBS clearance.
Your day-to-day might include troubleshooting electrical or avionic faults using technical data, maintaining systems such as radar, navigation, autopilot, flight instruments, and mission electronics. Experience with these different systems and tools is important for this role. You will also be required to conduct continuity checks, as well as insulation and functional tests. You will also be supporting on-craft configurations changes and modifications.
You’ll collaborate closely with B1 mechanical engineers, weapons specialists, and military engineering personnel. Depending on the environment, you may support flight‑line operations, hangar/depth maintenance, system upgrades, or engineering trials. This role suits meticulous engineers who enjoy technical complexity, precision, and working within disciplined, safety‑critical teams.
How to Become a B2 Engineer
There are multiple pathways into becoming a B2 Engineer. Some common progression routes include completing a Part-66 B2 licence (either through modular or integrated training). Others complete an aeronautical engineering course (Level 3 to 5). You can also progress from other military avionic technician roles or through aerospace apprenticeships. To become a B2 Engineer, you will need security clearance such as BPSS.
What to Put on a B2 Engineer CV
A strong B2 Engineer CV should clearly demonstrate your avionics expertise, platform experience, and certifying capability. You will want to include your experience with platforms and environments, including different rotary aircraft, fixed-wing, or specialist defence platforms. Avionic system experience such as sensors, radars, mission systems, and flight-control electronics is also essential for this role. Make sure to highlight your certifications and compliance, as these are crucial for defence sector roles.
