Embedded Systems Engineer

# **Why Tractable?** We combine world-class AI research with real-world applications that make a difference. At Tractable, you’ll collaborate with brilliant minds, work on transformative projects, and contribute to technology that helps people when they need it most. ## **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. This role sits at the intersection of embedded software, hardware integration, and sensor/vision data processing. ## **What you’ll do** - 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. ## **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. **Relevant 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. 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 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. **Contract type:** Permanent **Compensation:** $120-150k # **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 recognised. We encourage applications from candidates of all backgrounds and offer equal opportunities without discrimination.
