at ICEYE

• Job title: Senior C++ Engineer – Satellite Real-Time Control Systems
• Job type: Full Time
• Experience level: Senior
• Salary: Not specified
• Degree requirement: Bachelor's Degree
• Tech skills: Linux
• Location requirements: Hybrid, Helsinki, Finland

About the role

• Senior C++ Engineer writing and optimizing real-time software for satellite systems at ICEYE. Collaborating across technical teams to develop solutions for autonomous control in space.

Responsibilities

• Write and optimize real-time C++ code that meets strict determinism and latency budgets needed for safe and precise on-orbit execution.
• Build & own the software layer that bridges sensors, actuators and control algorithms - deterministic loops, telemetry pipelines and on-orbit autonomy.
• Drive quality through full development lifecycle: requirements → design → code → HIL/MIL testing → launch → on-orbit support.
• Collaborate with GNC, electronics, ground-segment and mission-ops engineers to debug, iterate and improve performance.
• Lead architecture evolution as our fleet and use-cases grow—refactor, optimise and introduce new technologies where they add value.
• Investigate anomalies: deep-dive into flight telemetry, reproduce issues on ground and roll out fixes that keep the constellation healthy.

Requirements

• You love writing modern C++ and know what production-quality code looks like.
• Proven track record of shipping real-time control software for autonomous or safety-critical systems—satellites, drones, robotics, automotive…
• Understand hard real-time constraints, latency budgeting and deterministic behaviour.
• Comfortable interfacing with sensors, actuators and embedded Linux environments.
• Champion of good engineering practice: rigorous testing at all levels, CI/CD, clear documentation.
• Ownership through full software lifecycle—from whiteboard concepts to on-orbit maintenance.
• Clear communicator who enjoys solving problems with colleagues across disciplines.
