Powertrain Reverse Engineer
Project Summary
We operate an autonomous-driving fleet built on the Toyota Highlander hybrid platform. The added compute load draws significantly more power than the stock hybrid system was designed to supply, causing the high-voltage battery to deplete and trigger faults that take vehicles out of service. The vehicle CAN bus has already been decoded for driving functions, but the hybrid control system — charging logic, battery state of charge, and thermal management — remains undecoded. We are looking for someone to reverse-engineer these hybrid/powertrain signals and deliver an updated DBC file so we can monitor and ultimately resolve the battery-depletion issue.
Key Responsibilities & Deliverables
- Capture and analyze CAN traffic on-vehicle (with driver/technician support)
- Reverse-engineer undecoded hybrid battery, charging, thermal, and powertrain diagnostic signals
- Produce a validated, updated DBC file and submit it as a pull request to our repo
- Re-run captured data against the new DBC to validate signal accuracy
- Document decoded signals and methodology
Must-Have Skills
- Hands-on automotive CAN bus reverse engineering experience
- DBC file authoring/editing
- Proficiency with Vector CANalyzer/CANoe (or equivalent) for trace capture and analysis
- Working knowledge of hybrid/EV powertrain and battery management systems (BMS)
- Comfortable reading raw CAN traces and isolating/decoding unknown signals
- Version control / Git pull-request workflow
Preferred / Nice-to-Have
- Direct experience with Toyota hybrid systems (THS) and Toyota diagnostics (Techstream/TIS)
- Python (or similar) for CAN data analysis
- Familiarity with AI-assisted coding tools (e.g., Cursor/Claude) — we use these to accelerate decoding
- Prior work decoding OEM “black box” control modules
Tools & Resources Provided
TIS laptop, CANalyzer, Cursor, Claude, GitHub access, scheduled vehicle time, plus VO driver, technician (TIS access), and supporting/firmware engineers.
Salary Range: $120,000-$135,000/K
