Senior Avionics and Embedded Systems Engineer

Full-time · Hybrid · Croatia

You'll lead the development of flight-critical avionics and embedded systems from early architecture and requirements through hardware and software development, integration, and testing.

You'll work closely with sub-system teams to develop robust, reliable, and flight-ready avionics capable of operating through one of the most demanding environments in aerospace, from launch through atmospheric reentry and recovery.

This is a hands-on engineering role for someone who wants genuine technical ownership and enjoys complex avionics and embedded systems challenges

What You'll Do

• Lead the avionics and embedded systems development of reentry vehicles, from initial architecture and concept studies through detailed design, integration and testing
• Develop the vehicle avionics architecture, including flight computers, power systems, sensors, actuators, communications, data acquisition, and associated embedded electronics.
• Design, develop, integrate, and test embedded software and firmware for mission-critical applications.
• Develop and implement data acquisition, telemetry, command, control, and vehicle health-monitoring systems .
• Support the development and integration of guidance, navigation, and control (GNC) systems.
• Support EMC/EMI, grounding, shielding, and electrical architecture development.
• Develop verification procedures, test plans, and acceptance criteria for avionics hardware and embedded software.
• Work closely with suppliers and manufacturing partners when required.

What We're Looking For

• Degree in Electrical Engineering, Electronics Engineering, Computer Engineering, Aerospace Engineering , or a related technical field.
• Professional experience in avionics, embedded systems, flight software, aerospace electronics, or related hardware development .
• Experience designing and developing real flight hardware , not only software or simulations.
• Ability to take ownership of avionics development from architecture and requirements through integration, testing, and flight.
• Experience with PCB design, and laboratory test equipment.
• Experience with avionics interfaces and communication protocols.
• Understanding of system-level electrical architecture, power distribution, signal integrity, EMC/EMI, and grounding.
• Experience with version control, software development workflows, and engineering documentation.
• Ability to work across disciplines and communicate effectively with engineers working on other subsystems.
• Strong analytical and problem-solving skills.
• A hands-on mindset and attention to detail
• Ability to work independently while coordinating technical activities with the wider engineering team.

Strongly Valued

• Experience with reentry vehicles, spacecraft, launch vehicles, rockets, hypersonic systems, or other aerospace systems .
• Experience with flight computers
• Experience with GNC, inertial navigation, or flight dynamics .
• Experience developing avionics for extreme aerospace environments
• Experience with hardware-in-the-loop or software-in-the-loop testing.
• Experience with environmental, vibration, thermal, EMC/EMI, or qualification testing.
• Experience with telemetry, command, ground stations, and mission operations.
• Experience with modular and fail-safe design
• Experience working in a startup or highly multidisciplinary engineering environment.
• Experience with aerospace development standards and structured verification processes.

How You'll Work

This is a full-time position which is mainly remote, but does require ocassional onsite presence in Croatia.

Because our development is closely tied to hardware, electronics integration, testing, and mission milestones, hands-on collaboration in person will be an important part of the role .

You'll work closely with engineers across avionics, systems, propulsion, structures, payload, thermal protection, and simulation, with the opportunity to influence the vehicle architecture rather than working within a narrowly defined engineering function.
