Senior Backend Software Engineer

The Role:

Due to team growth, we are seeking an experienced Software Engineer to join our Sat OS team, which develops the high-level operating system and file transfer layer for the spacecraft

The successful candidate will play a crucial role in developing software for our satellite systems, contributing to the expansion and enhancement of our space and ground-based data transfer capabilities. 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 Sat OS Software Engineer:

• Develop and enhance satellite-side applications with a focus on file transfer to and from the satellite and its payloads

• Contribute to the design and implementation of the next generation of Spire’s File Transfer architecture (Rust)

• Ensure that Spire’s file transfer services meet internal and mission-driven security standards

• Enhance observability and fault-tolerance of Spire’s file transfer services

• Take responsibility for the performance of critical file transfer services that contribute to the movement of data to and from Spire’s entire fleet of nanosatellites

• Contribute to the design and implementation of highly available, fault-tolerant systems to meet the demands of new customer missions

• Perform ground-based testing and in-orbit verification of new software services

• Coordinate closely with Spire’s communications team, systems engineering, product owners, and internal customers to ensure alignment and optimal integration with interfacing hardware and software services

• Create and maintain comprehensive documentation for APIs and system architectures

• Implement observability solutions for space and ground-based services to provide a clear and actionable view of service performance

**Basic Skills/Qualifications:

• 5+ years’ experience in professional software development

• Proven experience in production-grade software development using at least one compiled language

• Proficiency in Python or equivalent high-level language

• Knowledge of Linux-based development

• Excellent documentation, collaboration, and communication skills

• Systems-level thinking (distributed, scalable, highly available) with an appetite for creating and adapting applications
