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. LumaScanner is our hardware-plus-SaaS vehicle scanning system: a drive-through scanner installed at dealerships, collision shops and insurer sites that pushes vehicle damage assessment toward real-time AI identification and repair estimation. LumaScanner started as a small, scrappy project and is fast becoming a major revenue line. Our Salt Lake City team designs, builds and supports it - hands-on work, close to the hardware, with startup pace and real ownership, backed by the data and funding of a company that has already proven the model at scale. 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 an Embedded Systems Engineer to help build and evolve the device-side (edge) software and firmware stack - controlling cameras and sensors, synchronizing capture, and building new measurement capabilities. The role sits at the intersection of embedded software, hardware integration, and sensor/vision data processing. You’ll take features from quick prototype through to production-grade reliability, and you’ll see them run on real vehicles. What you’ll do • Build and maintain embedded Linux software and firmware for the camera and sensor stack. • 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 • 3+ years of experience in embedded engineering. • Production coding in C/C++ and/or Python, backed by strong software engineering fundamentals (OOP, testing, debugging, version control). • Embedded Linux expertise, including system services, supervision, logging, and performance profiling. • Hands-on hardware & sensor integration using standard protocols (UART, I2C, SPI, GPIO) and industrial interfaces (RS-485, CAN, or Modbus). • Practical lab & bring-up skills: proficient with oscilloscopes, logic analyzers, multimeters, basic soldering/wiring, and reading datasheets/schematics. • 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 tough problems, and ship maintainable systems in a fast-paced environment. What success looks like • Camera and sensor stacks run reliably for months, with clear telemetry and graceful recovery. • New capabilities move from prototype → validated pipeline → production release. • Hardware bring-up gets faster over time as tooling, test harnesses, and standards improve.
