Senior Waveform Architect (All Genders)

Stark; Berlin; On-site; EUR 120,000 - 170,000; Full time

Job summary

STARK is redefining autonomous, heavily shielded defence platforms. As Senior Waveform Architect, you will own the PHY waveform development, from architecture to real-time execution, ensuring robust links under severe electronic countermeasures.

You will lead FPGA/SoC implementations, tackle challenging jamming scenarios, and define HDL guidelines while exposing key observables for the Direction Finding strand. Berlin-based role with NATO-focused projects.

Qualifications

• Experience designing PHY and implementing on FPGA/SoC hardware in real time.
• Strong experience with synchronisation, estimation, FEC, and link budgets.
• Hands-on debugging of real radio links on hardware.
• Evidence of PHY implementation such as GNU Radio modules or RFSoC toolchain contributions.

Responsibilities

• Lead the design and implementation of the PHY waveform, from architecture to real-time execution.
• Engineer solutions for challenging jamming scenarios and multi-node long-range links.
• Own PHY-side specifications and expose IQ, phase, timing observables for DF.
• Define development guidelines for HDL and verification conventions, and FPGA build flows.

Job description

About Us

STARK is a defence technology company redefining the engineering and deployment of autonomous platforms. Our core mission is to deliver fully operational unmanned systems, integrating the critical subsystems, including Electronic Warfare, necessary for NATO forces to maintain a decisive advantage in contested environments. We do whatever is required to achieve platform autonomy, grounded in precision, responsibility, and uncompromising engineering discipline.

About the team

We are a lean, agile group with a strong systems-minded focus. We operate without silos, seeking visionary technical leaders who can define long‑term technology roadmaps while remaining deeply hands‑on with complex engineering problems. On the Electronic Warfare team, you will hold the highest level of technical authority for our attack and countermeasure capabilities, driving multi‑domain architectures directly onto the modern battlefield.

Your mission

At STARK, we are building the next generation of autonomous platforms capable of navigating the world’s most contested environments. As a Senior Waveform Architect, you will own the entire development, architecture, and implementation of the waveform for our tactical anti‑jam radio. In this critical role, you will ensure our communication links remain highly robust and operational under severe electronic countermeasure conditions.

Responsibilities

• Lead the design and implementation of the physical layer (PHY)-waveform, modulation, coding, framing, and synchronisation‑from initial architecture to real‑time execution.
• Engineer solutions specifically tailored for challenging jamming scenarios and complex, multi‑node long‑range link budgets.
• Own the PHY‑side specifications and expose the critical IQ, phase, and timing observables required by the Direction Finding (DF) strand.
• Define the development guidelines for the strand‑including HDL and verification conventions, as well as FPGA build flows.

Qualifications

• You have successfully designed a PHY and brought it onto FPGA/SoC hardware in real time.
• You are quantitatively sure‑footed on synchronisation, estimation, FEC (Forward Error Correction), and link budgets.
• You have practical experience debugging real radio links against physical hardware.
• Publicly verifiable PHY implementation evidence (e.g., custom GNU Radio OOT modules or contributions to the RFSoC toolchain).

Nice to have

• Experience with anti‑jamming and LPI/LPD (Low Probability of Intercept/Detection) in a tactical context.
• A professional background at industry leaders.
