Senior 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. Tractable is a leader in AI for auto repair and insurance, backed by SoftBank, Insight Partners, and Georgian. LUMA is our internal startup: a small Salt Lake City team building a drive-through scanner that pushes vehicle damage assessment toward real-time AI identification and repair estimation. Our Salt Lake City office is home to the small team that designs, builds, and produces the LUMA scanner - hands-on work, close to the hardware. Expect startup pace and real ownership, backed by the data and funding of a company that has already proven the model at scale. As a senior engineer, you’ll help shape how the team builds. 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 produce high-fidelity vehicle imagery and measurements. We’re looking for a Senior Embedded Systems Engineer to own and evolve the device-side (edge) software and firmware stack - controlling cameras and sensors, synchronizing capture, and building new measurement capabilities. You’ll set technical direction for the embedded stack, mentor other engineers, and take features from quick prototype through to production-grade reliability on real vehicles. The role sits at the intersection of embedded software, hardware integration, and sensor/vision data processing. What you’ll do Architect embedded Linux software and firmware systems for the camera and sensor stack. Provide technical leadership and guidance across embedded software, firmware, and electrical systems; set best practices and mentor other engineers. Bring up custom camera and sensor subsystems end to end. Maintain and improve camera control software: triggering, timing, health monitoring, and error recovery. Maintain and improve sensor control software: presence/distance/measurement sensors, calibration, and fault handling. Build signal processing pipelines - e.g. converting laser-triangulation outputs into 2D tread-depth maps, post-processing stereo depth, filtering/denoising, and coordinate transforms. Prototype fast, then harden to production-grade reliability. Support integration and deployments: bring up new modules, validate in the lab and on-vehicle, debug issues, and ship fixes. What we’re looking for 6+ years of embedded engineering experience, with a proven track record of architecting and shipping production-grade systems. Technical leadership capabilities, including mentoring engineers and driving system architecture decisions. Production coding in C/C++ and/or Python, backed by strong system design and software fundamentals (OOP, testing, reliability, version control). Embedded Linux expertise, including system services, supervision, logging, and performance profiling. Hands-on hardware & sensor integration: safely and cleanly connecting sensors to compute hardware using standard protocols (UART, I2C, SPI, GPIO) and industrial interfaces (RS-485, CAN, or Modbus). Practical lab & bring-up skills: proficient with test equipment (oscilloscopes, logic analyzers, multimeters), soldering, crimping/connectors, board bring-up, and reasoning about board-level schematics/datasheets. Modern developer workflow: experience using AI coding tools (Cursor, Claude Code, OpenAI Codex) to rapidly iterate high-quality code. Ownership mindset: ability to navigate ambiguous requirements, solve complex problems, and deliver maintainable systems in a fast-paced environment. Contract type: Permanent Compensation: $150-180k + equity 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.
