About Lynk

Lynk is the inventor of satellite direct to standard phone technology aka sat2phone and has the worlds only commercial license from the FCC to operate a commercial sat2phone system. Today Lynk allows mobile network operators subscribers to send and receive text messages to and from space via standard unmodified mobile devices. Lynks service has been tested and proven on all seven continents has regulatory approvals in more than 30 countries and is currently being deployed commercially based on more than 40 MNO commercial service contracts covering approximately 50 countries.

Our technology will enable all 8 billion people on the planet to stay connected with the existing standard phone in their pocket. Everywhere. No matter what.

By joining Lynk you will have the opportunity to directly touch the lives of billions. Your mission will be to bring mobile broadband to billions pull hundreds of millions out of poverty and save countless lives.

Job Summary

The Flight Software Engineer at Lynk 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 youve built embedded or autonomy software in an adjacent domain robotics automotive drones or similar youll 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 Lynks 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 Bachelors 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.
