We are seeking an experienced Embedded Software Engineer to join our Platform team supporting Spacecraft Operations. 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 Embedded Software 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-RK1
