Are you ready to embark on this exciting journey with us?

Loft Federal’s Software group provides the on-orbit software that powers our satellite fleet — from the Linux services running on the Hub’s onboard computers, to the containerized workloads executing customer applications in low Earth orbit.

The applications developed by our team handle the low-level communication protocol details, exposing the connected devices behind standardized APIs used across mission operations. The team is also responsible for the automation and orchestration that allows Loft to safely and reliably operate the equipment at scale.

In this Flight Software Engineer role, you’ll help develop the software that connects diverse spacecraft hardware to the rest of the platform, and ultimately enables successful missions in orbit.

What you'll do :

Design, implement, and refine software with a high degree of ownership, driving impactful features from concept through delivery while ensuring robustness and reliability.

Review code, provide clear feedback, and enforce adherence to established development processes, style guides, and design standards to maintain consistency and quality across the codebase.

Design and implement unit and integration tests for both self-authored and peer-authored code.

Utilize version control systems to create feature branches, push code, and merge approved code into production branches.

Contribute to the onboard software architecture through design proposals and collaborative review

Participate in the review and enhancement of software development processes and design standards.

Coordinate with downstream teams on the distribution and adoption of the latest releases.

In addition to responsibilities within onboard software, you’ll have the opportunity to directly be involved in operating our on-orbit fleet of satellites.
