Senior Firmware Engineer

We are seeking an experienced Embedded Software Engineer to join our Platform team (folks looking after the spacecraft). The successful candidate will play a crucial role in supporting other disciplines by focusing on the embedded software aspects of our satellite systems. The Platform team interfaces directly with many engineering groups to conduct R&D, design, manufacturing, and operations activities, ultimately ensuring all current and future spacecraft systems satisfy their mission. Ideal candidates will embrace the commercialization of nanosatellite systems and adapt to low-cost, fast-paced systems design, development, and implementation methodologies that set Spire apart from our competition. In this fast-paced environment, the design to launch cycle is measured in weeks and months, not years! What You’ll Do as a Senior Firmware Engineer: • Design, implement and test, deploy and maintain embedded firmware • Collaborate with other engineering functions on scoping, architecture and system design • Resolve on-orbit and on-ground issues related to embedded systems • Implement, optimize and maintain various serial protocols • Design and develop interface tools to improve abstraction between the embedded system and other satellite components • Debug and resolve complex embedded systems issues in a timely manner • Write and maintain technical documentation Key Skills: • Bachelor's degree in Computer Science, Electrical Engineering, or related field • Mastery of Embedded C programming language • Proficiency with scripting languages like Python and Bash • Extensive experience with real-time operating systems (RTOS), specifically FreeRTOS • Familiarity with serial protocols and implementations • Strong problem-solving skills, particularly in debugging embedded systems • Experience with version control systems (e.g., Git) • Experience developing on Linux (Ubuntu) • A base level of mathematical knowledge (engineering mathematic or similar) • Excellent communication and teamwork abilities Preferred Skills: • Experience with space systems or satellite technology • Familiarity working to coding standards and using static analysis tools • Experience writing Rust for resource constrained environments (embedded Linux) • Experience with embedded Linux • Knowledge of control systems and algorithms Tools and Technologies: • FreeRTOS for real-time operating system implementation • GNU ARM Embedded Toolchain for code compilation • GDB for debugging, complemented by extensive use of serial and/or CAN debugging • Experience with debugging techniques for systems without JTAG access, particularly for remote issue resolution • Familiarity with manual testing procedures for embedded interface code • Experience working with Arm Cortex Microcontrollers • Version control using Git Spire operates a hybrid work model, and this position will require you to work a minimum of three days per week in the office. Access to US export-controlled software and/or technology may be required for this role. If needed, Spire will arrange the necessary licenses—this is not something candidates need to have before applying. #LI-MI Global Perks 🛰️ Name Your Satellite Program (NYSP) 🚀 Launch Attendance 🌴 Generous Time Off Policy 🎓 Education Assistance Program 🥰 Employee Assistance Program (EAP) 📈 Employee Stock Purchase Program (ESPP) 👣 Family Leave 💪 Fitness Reimbursement 🧡 Employee Referral Program 🍉 Healthy snacks & beverages in every office About Spire We improve life on Earth with data from space.
