FPGA Design Engineer (m/f/d)

Job Description Summary

Job Description

Key responsibilities:

• Define FPGA architecture for:
  • Real-time communication and control loops.
  • Power electronics-specific functions (PWM, gating, protection, measurements).
  • Partition functions between FPGA, MCU/DSP, and other devices considering latency and determinism.
  • Select appropriate FPGA families and IP for timing-critical and safety-related functions.
• Develop synthesizable RTL (VHDL) for:
  • PWM generators (e.g., carrier-based, space-vector, multi-phase, interleaved, dead-time insertion, synchronised to grid or rotating frame).
  • Real-time communication interfaces (e.g., synchronous serial links, fieldbus/industrial Ethernet PHY interfaces, deterministic point-to-point links, custom high-speed serial).
  • Signal and clock reconstruction blocks (e.g., digital PLLs, phase tracking, clock domain crossing, resampling, and timestamping).
  • Measurement, protection, and monitoring logic (e.g., overcurrent, overvoltage, desaturation, fault latching, fast trips).
• Implement:
  • High-resolution timers and counters for gating signals.
  • Clock, reset, and synchronization schemes for multi-board/multi-FPGA systems.
  • Fixed-point digital signal processing as needed for filtering, estimation, or modulation.
• Develop testbenches and simulations to verify:
  • PWM timing accuracy, dead-time behavior, and jitter performance.
  • Real-time communications latency, robustness, and error handling.
  • Correct operation of signal/clock reconstruction (phase tracking, frequency changes, grid disturbances).
• Perform static timing analysis and timing closure for:
  • Tight real-time constraints (fast control loops, sub-µs reaction times).
  • Multiple clock domains and asynchronous interfaces.
• Support lab and field testing:
  • Board bring-up and system integration.
  • Debugging under real operating conditions using oscilloscopes, logic analyzers, current/voltage probes, and protocol analyzers.
• Create and maintain documentation:
  • FPGA specifications, timing budgets, and interface definitions.
  • Verification plans, test reports, and release notes.
• Support production and field updates (JTAG, in-system programming, secure and fail-safe update mechanisms).

YourProfile:

• Bachelor’s or Master’s degree in Electrical Engineering, Information Technology, Computer Engineering, or a related field, with a focus on FPGA or digital hardware design.
• Several years of professional experience in FPGA design, preferably in real-time, control, or power electronics applications.
• Strong proficiency in VHDL and a solid understanding of synthesizable RTL design, timing constraints, and clock domain crossing techniques.
• Hands-on experience with at least one major FPGA vendor toolchain.
• Experience with time-critical logic such as PWM generation, high-resolution timers, or communication interfaces.
• Fluency in English is required; German is a plus.

Key Competencies:

• Strong problem- solving skills in time-critical and safety-related systems.
• High attention to detail, especially regarding timing, jitter, and protection logic.
• Ability to collaborate with control, power electronics, hardware, and firmware teams.
• Clear communication of complex timing and architecture decisions.
