Constantin Chabirand

Embedded Software Engineer & Architect — real-time firmware, multicore SoCs, safety & cybersecurity, AI-augmented — now hands-on in coherent optical communications. Munich, Germany. Open to relocating to the USA (J-1 Research Scholar or Specialist via Cultural Vistas / IREX, or H-1B).

Summary

9 years shipping production firmware: real-time control, DSP, multicore ARM, bare-metal, functional safety to ASIL-D. ECUs in production vehicles for Mercedes-Benz, VW, BMW, Tesla, Continental.
Founded and scaled an embedded engineering practice from 1 to 60+ engineers (€11.2M annual revenue); founded the AUTOSAR Academy; Vector CEP certified.
Hands-on in coherent optical communications: DARPA Space-BACN (sole firmware engineer, free-space optical terminal) and ESA Pegasus (coherent-DWDM transport — WSS, superchannels, OSNR/BER, up to 400G). Owns on-MCU DSP and microsecond control loops: blind polarization control, runtime-reconfigurable FIR demod, DDS pilot tones.
Why automotive → optics: eight years of ASIL-D discipline (formal timing budgets, deterministic scheduling, first-time-right bring-up) applied to coherent optical links that must never drop lock.
AI-augmented builder: multi-model orchestration (PowerSpawn) and self-built tooling (Radeau), ~3–5× delivery velocity.
