Signal Processing Engineer (GNSS) - Athens, Hybrid (3-2)

Our client is a Swiss fabless semiconductor company specialising in embedded GNSS positioning and wireless communication chips and modules products relied on by millions of users worldwide. With around 850 employees across 21 countries, their Athens engineering site hosts the GNSS Measurement Engine (ME) team within the high-precision positioning R&D organisation. This role is open to grow the Athens team and add capacity to the wider cross-site engineering group.

The Role

You'll join a small, focused team of exceptionally skilled engineers and own GNSS receiver features end to end from concept through modelling and simulation, embedded implementation, and verification to release. Working in embedded C on real silicon, you'll prototype algorithms in MATLAB/Python, write and adapt the drivers that bridge the chip's processor and its signal-processing hardware blocks, and debug on real hardware alongside the HW/ASIC designers. In your first months you'll get across a large, interdependent codebase, take on test-driven feature development, and start contributing to a cross-site agile team. Your output feeds the Positioning Engine that turns raw signal data into a position fix.

What You'll Bring

• Strong embedded C, able to read and work in a real, complex codebase from day one
• A signal-processing background with GNSS or Layer-1 (physical-layer) wireless knowledge satellite comms, Wi-Fi or Bluetooth all relevant
• MATLAB and/or Python for algorithm modelling, simulation and verification
• Firmware development on hardware chips, with hands-on debugging and close collaboration with HW/ASIC designers on requirements and test routines
• Comfortable working in an agile/scrum environment
• A degree in Electrical Engineering, Telecommunications, DSP or Computer Science
• 2+ years' hands-on industry experience (domain knowledge prioritised over years)
• Pragmatic, detail-focused and analytical a "makes it happen" engineer and strong team player
• A good communicator, fluent in English (international, multi-site team)

Nice to Have

• FPGA (VHDL/Verilog) and hardware emulation
• GNSS position-computation knowledge and an understanding of ME ↔ Positioning Engine interaction
• Python test scripting and full MATLAB → Python development-cycle experience
• A Master's or PhD in EE, Telecommunications or DSP
• Semiconductor industry or GNSS test-engineering experience

What's in it for You

€3,300 – €3,700 annual gross commensurate with experience, plus an annual cash bonus of up to 15%, a pension/savings plan with company matching up to 5%, and fully paid medical and life insurance. Enjoy lunch allowance of €132/month (11 months), a parking spot or public-transport card, and a hybrid working arrangement with 3 days in the Athens office and 2 from home, plus up to 10 days/year working from abroad (EU/UK).
