About Elveo

Elveo is what happens when two pioneers in direct-to-device (D2D) communications join forces. Elveo brings together a combined 20 years of expertise to close the coverage gap for more than 50 mobile network operators (MNOs) and major distribution partners operating in 60+ countries worldwide.

That heritage and our technology powers what we call ‘elevated intelligence’ — a new approach that processes and adapts on orbit, delivering voice and data services straight to mobile users, IoT devices and machines across enterprise, government and humanitarian sectors worldwide.

As a team, we’re on a mission to deliver powerful compute and connectivity directly to individuals and objects everywhere on Earth.

Join us, and become part of a globally inclusive company that is transforming satellite communications from a niche service to an essential global infrastructure, and democratizing connectivity for billions worldwide.

Job Summary

The Flight Software Engineer at Elveo will be developing flight software applications for commanding and controlling our satellites. This includes developing our satellite command and data handling system software, in addition to supporting software for both its primary (payload) and secondary radio communications functions. The software will initially be tested on the satellite prototype in a lab environment "flatsat" that simulates orbit operations. You will also be responsible for building the telemetry and instrumentation needed to capture data during tests and ensure successful verification and validation.

We build spacecraft fast! So, the ideal candidate enjoys designing, developing, and testing software on rapid timelines. We are looking for engineers who enjoy a challenge and have a track record of creative thinking to solve unconventional problems. This is a small team, so you will work alongside experienced engineers and take ownership of systems early.

Experience with satellites is not a requirement for this position. We welcome candidates across experience levels, from exceptional new graduates to seasoned engineers; title, scope, and compensation scale with experience. If you've built embedded or autonomy software in an adjacent domain — robotics, automotive, drones, or similar — you'll find much of your experience translates directly. If you are a systems-minded software engineer eager to take on an unfamiliar domain, we want to hear from you.

Core Responsibilities

You will contribute to the design, development, and testing of spacecraft flight software systems, including those that implement our spacecraft Command and Data Handling; Power; Communications; and Guidance, Navigation, and Control Systems. This includes:

Contributing to the design of software solutions critical to the operation of our spacecraft, and developing these as Linux applications that run on satellite flight systems.
Working in a small, agile team to execute the software development lifecycle (requirements definition, design, implementation, test, and verification) across many individual projects.
Participating in design and code reviews, and collaborating with the team to uphold best practices for the flight software codebase.
Supporting Elveo's Operations and Payload teams, who each bring unique demands on the satellite flight systems.
Creating embedded software to interact with satellite devices and electronics using CAN, I2C, SPI, RS-422, RS-485, and other protocols.
Implementing inter-application coordination and communications using standard inter-process communication (IPC) mechanisms available in Linux.
Developing test software to support unit, integration, and system testing of all flight software functions.
Building the telemetry, instrumentation, and data-capture tooling used to verify and validate flight software on our flatsat.

Basic Qualifications

Proficiency in at least one systems programming language such as C, C++, or Rust, demonstrated through professional work, significant academic/personal projects, or open-source contributions.
A willingness to work in the Rust programming language.
Familiarity with Linux and operating system principles.
Experience building software that interacts with hardware devices, or a strong systems background and eagerness to work close to hardware.
An understanding of the phases of the software development life cycle.
Experience writing automated tests for software you build.
Familiarity with Git and the fundamentals of CI/CD systems.
A Bachelor's degree or higher in Software, Computer, Electrical, Aerospace, or a related engineering field, or equivalent practical experience.

Preferred Qualifications

Several years of professional software engineering experience.
Network and socket programming experience, particularly for telemetry or commanding interfaces.
Experience with inter-process communication (IPC) mechanisms.
Advanced knowledge of the Rust programming language.
Familiarity with embedded Linux systems, including the Yocto/OpenEmbedded project.
Experience developing and testing software for SmallSats / CubeSats.
Experience with hardware-in-the-loop integration and testing.
Experience with Protocol Buffers, ZeroMQ, gRPC, and Systemd.
