About this job
Job Description
We are looking for a Lead Embedded Software Engineer to own the full path from product requirements to working, tested firmware. You will translate product-level goals into system software architecture, write production code, and lead a team of embedded engineers to ship reliable, high-performance software.
This is a player-coach role. You will write code every day while also guiding the team, reviewing designs, and setting technical direction. You must be as comfortable at a whiteboard as you are at a debugger. You will report to the head of product engineering.
What you will do:Architecture and Technical Leadership
• Translate product requirements into clear system-level software architecture.
• Define software interfaces, data flows, and module boundaries across the embedded stack.
• Make and own key technical decisions. Document them clearly for the team.
• Identify risks early and drive solutions before they become blockers.
Hands-on Development
• Write, review, and maintain production firmware in C/C++ (and Rust where applicable).
• Develop drivers, middleware, and application logic for sensor-rich embedded platforms.
• Work with Zephyr RTOS across multiple MCU families (STM32, Nordic nRF, ESP32).
• Use West and CMake to manage builds, module dependencies, and board configurations.
• Debug firmware using JTAG, SWD, logic analyzers, and oscilloscopes.
• Integrate and validate sensors including IMUs, accelerometers, and gyroscopes.
• Implement and optimize networking stacks - BLE, Thread, and Wi-Fi.
• Design and maintain backend communication protocols for reliable edge-to-cloud data transfer.
Test and Quality
• Write automated unit and integration tests before or alongside feature code.
• Build and maintain HIL (hardware-in-the-loop) and SIL (software-in-the-loop) test frameworks.
• Set team standards for test coverage, static analysis, and CI/CD pipelines.
• Perform code reviews with a focus on correctness, safety, and long-term maintainability.
Team Leadership
• Lead a small team of embedded engineers. Set clear goals and unblock day-to-day work.
• Mentor engineers through design reviews, pair programming, and direct feedback.
• Collaborate with hardware, systems, and product teams to align on requirements.
• Contribute to hiring - interview candidates and help define the team's technical bar.
Required
• 7+ years of embedded software development experience in production systems.
• Strong C/C++ skills in resource-constrained environments (bare-metal and RTOS).
• Hands-on experience with Zephyr RTOS, including West build system and CMake.
• Deep knowledge of at least one MCU family: STM32, Nordic nRF, or ESP32.
• Experience integrating and characterizing inertial sensors (IMU, accelerometer, gyroscope).
• Solid understanding of wireless protocols - BLE, Thread, and Wi-Fi - including their stack implementations.
• Experience designing and implementing backend communications (MQTT, CoAP, HTTP/REST, or similar).
• Strong skills in writing automated tests for embedded code: unit tests, mocking, HIL/SIL frameworks.
• Proficiency with hardware debug tooling: JTAG, SWD, logic analyzers, and oscilloscopes.
• Solid Git workflow practices: branching strategy, code review process, and CI/CD integration.
• Demonstrated ability to lead a technical team while remaining a hands-on contributor.
• Clear communicator. Able to explain complex technical decisions to non-specialist stakeholders.
Nice to Have
• Experience with Rust in embedded contexts.
• Familiarity with TinyML or edge ML frameworks (TFLite Micro, Edge Impulse, ONNX Runtime).
• Background in aerospace, satellite, or other safety-critical systems.
• Experience with model optimization techniques such as quantization and pruning.
• Contributions to open-source embedded or RTOS projects.
How We Work
• On-site, collaborative environment. We build physical hardware - presence matters.
• Small teams with high autonomy. You own your area end-to-end.
• Fast iteration cycles. We prototype, test, and revise quickly.
• Direct feedback culture. We expect candor and respect in equal measure.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
