We are looking for a Staff Firmware Engineer to provide technical leadership in the development of bespoke, safety- and security-critical embedded systems for defence products. You will shape firmware architecture and implementation across the product-development lifecycle, from requirements and design through integration, verification and qualification.
This is a hands-on technical role. You will set engineering direction, resolve complex embedded-systems problems and act as a trusted technical authority across firmware, hardware, systems, test and security disciplines.

10+ years of professional experience developing bare-metal and RTOS-based firmware for safety- or security-critical real-time systems in regulated sectors (e.g., defence, aerospace, or marine).
Deep expertise in low-level embedded systems (interrupts, scheduling, determinism, fault tolerance) with strong C and Modern C++ programming skills, supplemented by Python for automation.
Proven ability to debug complex hardware-software integration issues using test equipment and protocol analyzers, with familiarity targeting platforms like Infineon AURIX or ARM Cortex.
Practical experience across the full development lifecycle, utilizing safety-certified toolchains, static analysis, automated CI and firmware testing, and objective verification evidence.
A proactive, evidence-driven mindset capable of acting as a trusted Staff-level technical authority, communicating complex trade-offs clearly across multidisciplinary engineering teams.
Bachelor's or master's degree in computer science, Software Engineering, Electrical Engineering or a related technical discipline.
Professional fluency in English (must-have); German language proficiency is a strong plus.
Please note: You do not need to meet every single requirement to apply. We welcome motivated candidates who are eager to grow into the role and develop their expertise further.

Join a mission-driven European defense tech company at a pivotal stage of growth, where you can help shape meaningful technology, take ownership early, and grow with the business!
Competitive compensation package including a bonus opportunity
27 vacation days to start, increasing with tenure up to 30 days
Employer-supported pension contribution
Learning & development support and team events budget
Employee discounts and flexible benefits budget via Probonio
Hybrid working setup depending on role and team needs
Structured salary bands, levelling framework, and bi-annual development conversations
Referral bonus program, dog-friendly office, and relocation support where applicable

Own and evolve the foundational architecture, design, and implementation of safety- and security-critical real-time embedded firmware for defence products.
Translate complex system, safety, and security requirements into clear, verifiable firmware designs, maintaining full traceability across the V-model development lifecycle.
Design and implement robust bare-metal and RTOS-based components, including device drivers, custom hardware-abstraction layers (non-AUTOSAR), BSPs, and bootloaders.
Develop secure-update mechanisms and integrate hardware-security features (e.g., HSMs, PKI, anti-tamper mechanisms) to align with zero-trust security principles.
Build highly testable, deterministic firmware that operates consistently across target hardware, SIL, and HIL simulation environments.
Investigate and resolve complex hardware-software integration faults using systematic debugging techniques, schematics, JTAG probes, oscilloscopes, and logic analyzers.
Provide hands-on technical leadership, mentor cross-functional teams, and set the engineering direction across firmware, hardware, test, and security disciplines.
