Job summary

Eutelsat Communications SA is seeking a Senior Software Engineer to build the Linux platform software for the next generation of LEO, multi-orbit, and IRIS² user terminals. You will create a stable API layer above the modem and antenna subsystems, enabling seamless interaction with higher-level software for call setup, recovery, and field operations.

You will collaborate with modem and RF architects and external partners to deliver a constrained embedded system with real-time considerations,

Qualifications

Bachelor's or Master's degree in computer science, software engineering, electrical engineering or a related field.
10+ years of experience in software development, including embedded or systems software on Linux.
Strong hands-on experience with C++, including work on embedded systems and mission-critical applications.
Solid understanding of embedded systems, real-time constraints, concurrency, memory management and software architecture.
Experience designing and maintaining APIs and service interfaces intended to be consumed by other teams or systems, with attention to versioning and long-term stability.
Comfortable with Linux at system level: init and service management, IPC, sockets and networking, filesystems, permissions, and cross-compilation for embedded targets.
Proficiency with unit testing frameworks and methodologies, and with continuous integration on embedded targets.
Practical debugging skills across the software and hardware boundary: core dumps, tracing, profiling, and instrumentation of a running system.
Eagerness to learn and work with Rust; existing Rust experience is a plus.
Strong communication skills and the ability to work independently or collaboratively, including with engineers from partner organisations.
Comfortable building a capability rather than inheriting one, with little existing tooling or process to rely on.
Eligibility under applicable European and United States export control regulations.
Fluent professional English.

Responsibilities

Collaborate across teams to translate product, service and operational requirements into robust technical implementations.
Design, develop and maintain the terminal platform software on embedded Linux: system services, device abstraction, inter-process communication, lifecycle and state management, and the boundary towards the modem and antenna subsystems.
Design and maintain the terminal APIs: local and remote control interfaces, configuration, telemetry and event streams, versioning and backward compatibility, and the contract they establish with our ground systems and management platforms.
Implement the control and monitoring paths towards the modem and the antenna manager: command sequencing, state synchronisation, error propagation, and the timing constraints these interfaces impose.
Build the observability of the terminal: structured logging, metrics, event and fault reporting, capture of diagnostic data, and the remote access paths our field and Tier-4 support teams depend on.
Own secure and reliable software update in the field: image management, roll-back and fail-safe behaviour, integrity and authenticity verification, and recovery from interrupted updates.
Write and maintain unit and integration tests, and build the automation that keeps the platform verifiable as it grows.
Participate in code reviews, architecture discussions and delivery processes, including joint reviews with external engineering partners.
Assist in system validation, debugging and troubleshooting of complex issues across the software, firmware and hardware boundary, in the laboratory and on deployed terminals.
Contribute to the board support package and integration work: build system, root filesystem, device drivers and kernel interfaces, boot and resource partitioning on a system on chip shared with real-time functions.
Mentor engineers and promote best practice in software design, testability and maintainability.
Engage professionally with internal stakeholders, partners and customers to ensure the platform serves the operational reality rather than the specification alone.
