Senior Embedded Software Engineer at Spire

Company: Spire
Location: Glasgow
Employment type: full-time
Posted: 2026-09-15

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
