BMS Engineer

Overview  At Elysian Aircraft, we are crafting a vision for the future of aviation. Supported by industry leaders and global organizations, our mission to create the aircraft of the future is already taking flight. We are engineers. We are pilots. We are builders. We don’t chase hype. We are true to science. Like the pioneers of aviation, we build what doesn’t exist yet.

We welcome people who bring different perspectives, backgrounds, and paths. New angles fuel honest debates to challenge conventions when the problems are first-of-a-kind. This is Elysian and we are on a mission to enable the electrification of the aerospace industry. If that makes your pulse rise, come build with us.
Your Mission   Support the design, integration, and verification of the battery management system (BMS) for a safety-critical battery-electric aircraft.
Turn BMS requirements into tested, traceable behaviours (normal and fault cases).
Improve integration readiness by finding issues early through bench/HIL tests and clean evidence.
Keep the BMS reviewable: clear interfaces, controlled changes, reproducible results.
Day-to-Day   Support BMS requirements capture (functional, safety, interfaces) and keep them traceable to verification evidence.
Help define BMS sensing and monitoring (cell voltages, temperatures, currents) and support architecture trade-offs with guidance.
Implement and test BMS features (state estimation, protections, limits, fault handling) under supervision.
Support supplier co-development (review specs, test plans, interface control documents).
Build and maintain test set-ups (HIL, bench, pack-level) and run scripted test campaigns.
Analyse logs, reproduce issues, propose fixes, and document results in clear test reports.
Support FMEA-style thinking: identify likely failure modes and help verify detection/mitigation.
Work closely with battery pack, powertrain, and software teams to close integration issues.
Traits For Success   BSc/MSc in Electrical, Embedded, Mechatronics, or similar.
2-4 years’ experience (or internships) in embedded systems, controls, or battery systems.
Basic understanding of batteries and BMS fundamentals (protections, balancing, sensing).
Hands-on ability: wiring, instrumentation, bench testing, safe lab practices.
Comfortable reading schematics and debugging with basic test equipment (multimeter, oscilloscope).
Ability to write simple analysis scripts to process test data.
Care for traceability and configuration control (versions, changes, evidence organised).
Clear written communication in technical notes and test reports.
Nice-to-have   

Experience with CAN, UDS, or similar automotive/aerospace comms.
Exposure to HIL tools or embedded CI test practices.
Familiarity with functional safety concepts (FMEA/FHA-level; no certification claims).
