Ideal candidates will embrace the commercialisation 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!

Develop services in Python/Rust that interface with hardware integration layers using modern protocols
Implement communication interfaces between higher-level processes, including ground to space commanding
Migrate legacy Python systems to a new Rust-based, distributed architecture
Contribute to the design and implementation of fault-tolerant systems to meet the demands of new customer missions

Collaborate closely with the Platform Engineering team to ensure optimal software-hardware integration

Create and maintain comprehensive documentation for APIs and system architectures

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
Experience with inter-process communication protocols (such as gRPC)
Ability to communicate effectively with embedded software engineers
Excellent documentation skills
Good customer relations skills

Preferred Skills:

Familiarity with safety-critical software systems in any industry

Knowledge of version control systems, particularly Git and GitHub

Familiarity with CI/CD pipelines

Experience with project management tools

Proficiency in scripting languages like Bash

Proficiency in Python and Rust

Understanding of cybersecurity principles systems

Knowledge of telemetry and command systems

Experience in implementing Fault Detection, Isolation, and Recovery (FDIR) systems for high-level or embedded applications

Tools and Technologies:

Python, Rust, Bash
Ubuntu (development environment)
gRPC (inter-process communications)

We value adaptability and a willingness to learn new tools and technologies as needed for the role.

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.
