Autonomy Embedded Engineer

• Joby's Advanced Development group is looking for an engineer to own and grow our hardware-in-the-loop and test-automation capability for novel aircraft and flight automation systems.
• This role is responsible for the fidelity, coverage, and reliability of the pipeline that allows us to test all new changes to our redundant compute system ahead of deployment.
• You will work closely with the core software team, flight controls, avionics, and flight test engineers who depend on this infrastructure.
• We're looking for someone who thrives in fast-paced environments, takes full ownership of infrastructure the whole flight software org relies on, and consistently delivers high-impact results.
• Develop and maintain the test infrastructure, fault injection frameworks and annunciation mechanisms required for in-the-loop testing
• Develop software in the loop, hardware in the loop and aircraft in the loop simulation infrastructure: in-the-loop scenario runner, simulated peripherals, and per mode configuration
• Bring up, debug, and maintain the physical HITL rigs, and keep rig hardware and configuration matched to the real aircraft they stand in for
• Build and extend hardware-CI pipelines that deploy flight software to rig hardware and run pass/fail, timing, and platform-log checks automatically, with results stored for trend tracking
• Write and maintain Bazel-based C++ and Python scenario and unit tests, including property-based tests, that exercise the flight software against realistic sensor, actuator, timing, and network-transport conditions
• Integrate new sensors and actuators into both the simulated and hardware-in-the-loop environments over their native buses (CAN, UART/RS-485, I2C, SPI, ARINC 429, Ethernet)
• Triage rig and CI failures: separate simulation-fidelity gaps from rig hardware faults from real flight-software bugs, and drive each to the right owner with a reproducible case
• Work with flight test and controls engineers to convert observed flight behavior into repeatable in-the-loop scenarios, closing the loop between flight data and pre-flight validation
• Strong C++ and Python, and fluency with Git
• Experience building or maintaining hardware in the loop or comparable automated test infrastructure that runs real embedded hardware in CI
• Working knowledge of embedded communication buses (CAN, UART/RS-485, I2C, SPI, or similar) at the level needed to debug them with a scope or logic analyzer
• Understanding of real-time and safety-critical software concepts: deterministic fixed-rate execution, timing budgets, redundancy, and what makes a test of such a system trustworthy
• Experience with a hermetic build system (Bazel or equivalent) and a CI system (Buildkite, Jenkins, GitHub Actions, or equivalent)
• Experience with Linux, including remote deployment and debugging on embedded Linux targets
• A passion for clean, long-lived, and readable object-oriented software architecture. Not just working code, but code built to survive years of extension by other engineers
• Property-based testing experience
• Experience with pub/sub or message-bus middleware for distributed embedded software (DDS, ROS 2, or a custom transport)
• Hands-on experience with servos, motor controllers, or other actuators on serial or CAN buses
• Experience designing or reviewing simple electrical hardware (PCBs, harnesses, breakout boards) to support test rigs
• Experience analyzing flight or test log data at scale (SQL, Databricks, or similar) to find regressions or derive new test cases
