Lead Embedded Systems Software Engineer

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place! E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems. We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life. 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. What we are looking for: 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, 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. This is a full time, exempt position, based out of our Saratoga office. The total compensation packaged will be determined by various factors such as your relevant job-related knowledge, skills, and experience. We are redefining how satellites are designed, manufactured and used—so we’re looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in-orbit activities. If that’s your experience – then we’ll be immediately wow-ed. E-Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role. In your first 90 days, you will have mapped the current embedded software architecture, identified the highest-priority gaps, and shipped at least one meaningful feature end-to-end. Within six months, you will have established a team testing standard, introduced measurable improvements to firmware reliability, and built strong working relationships with hardware and systems engineering. 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.
