Embedded Systems Engineer

About the role

We’re building LUMA, a drive-through vehicle inspection scanner that combines multi-camera capture, active illumination, and multiple sensor modalities to generate high-fidelity vehicle imagery and measurements. We’re looking for an Embedded Systems Engineer to own and evolve the device-side software/firmware stack that controls cameras and sensors, synchronizes capture, and enables new measurement capabilities.

Responsibilities

• Maintain and improve camera control software (triggering, timing, health monitoring, error recovery).
• Maintain and improve sensor control software (presence/distance/measurement sensors, calibration, fault handling).
• Develop new scanner capabilities.
• Implement signal processing pipelines (e.g., convert laser triangulation outputs into 2D tread-depth maps; post-process stereo depth results; filtering/denoising; coordinate transforms).
• Prototype quickly, then harden implementations to production-grade reliability.
• Support system integration and deployments: bring up new modules, validate in the lab/on-vehicle, debug issues, and ship fixes.

Requirements

• Strong software engineering fundamentals (debugging, testing, reliability, version control).
• Experience integrating sensors/devices in real-world systems.
• Comfort working close to hardware: bring-up, wiring, and iterative troubleshooting.
• Ability to take ambiguous requirements and ship maintainable systems.
• Embedded/edge platforms: Raspberry Pi, NVIDIA Jetson, Arduino (or similar).
• Protocols and interfaces: RS-485, CAN, Modbus, UART/I2C/SPI, GPIO.
• Linux-based device development: system services, supervision, logging, performance profiling.
• Container based application development: Docker or similar container runtimes.
• Sensor/vision data processing: filtering, calibration, synchronization, map generation.
• Hands-on electronics: able to connect sensors to compute hardware safely and cleanly.
• Comfortable with basic soldering, crimping/connectors, and reading datasheets/wiring diagrams.

Preferred Requirements

• Computer vision/depth sensing experience (stereo, structured light, LiDAR, triangulation).
• Multi-device synchronization (timestamps, trigger distribution, drift management).
• Queue based job management e.g. Redis worker queues.
• Production deployments (monitoring, remote updates, failure analysis).
• Python + C/C++ (and/or Rust/Go) in mixed systems.
• Familiarity with camera control APIs and image capture pipelines.
• Familiarity with IoT fleet management software such as AWS IoT, Balena Cloud, etc.

What We’re Looking For

Core requirements: Strong software engineering fundamentals (debugging, testing, reliability, version control). Experience integrating sensors/devices in real-world systems. Comfort working close to hardware: bring-up, wiring, and iterative troubleshooting. Ability to take ambiguous requirements and ship maintainable systems.

Technical Experience

• Embedded/edge platforms: Raspberry Pi, NVIDIA Jetson, Arduino (or similar).
• Protocols and interfaces: RS-485, CAN, Modbus, UART/I2C/SPI, GPIO.
• Linux-based device development: system services, supervision, logging, performance profiling.
• Container based application development: Docker or similar container runtimes.
• Sensor/vision data processing: filtering, calibration, synchronization, map generation.

Hands-on Electronics

• Able to connect sensors to compute hardware safely and cleanly.
• Comfortable with basic soldering, crimping/connectors, and reading datasheets/wiring diagrams.

Success Looks Like

• Camera and sensor stacks run reliably for weeks with clear telemetry and graceful recovery.
• New capabilities move from prototype to validated pipeline to production-ready release.
• Hardware bring-up time decreases as tooling, test harnesses, and standards improve.

Diversity Commitment

At Tractable, we are committed to building a diverse team and inclusive workplace where people’s varied backgrounds and experiences are valued and recognized. We encourage applications from candidates of all backgrounds and offer equal opportunities without discrimination.
