ICEYE is the global leader in synthetic aperture radar (SAR) satellite technology, revolutionizing Earth observation with real-time, all-weather, day-and-night imaging. As the owner and operator of the world's largest SAR satellite constellation, we provide critical insights that empower industries like defense, maritime, disaster management, insurance, and finance to make informed decisions.
Headquartered in Finland and operating internationally with offices in Finland, Poland, Spain, Japan, the UAE, Greece, and the US, our diverse team of more than 900 experts from nearly 60 countries shares a bold mission: to enhance life on Earth by delivering reliable, data-driven solutions. At ICEYE, we foster a culture of curiosity, innovation, and collaboration, pushing the boundaries of what's possible in space technology to solve the world's toughest challenges.
At ICEYE, we're not just launching satellites — we're redefining what's possible with SAR technology. Join a team of passionate innovators solving real-world challenges and making a tangible impact. We foster a dynamic and inclusive environment where your ideas are valued, your growth is supported, and your contributions truly matter. With continuous learning opportunities, cutting-edge projects, and collaboration with industry-leading experts, you'll have the chance to grow, innovate, and shape the future of Earth Observation.
ICEYE is seeking a Mechanical AIT (Assembly, Integration & Testing) Engineer to own the mechanical side of production end to end -- integration, testing, supplier selection, continuous improvement, and adapting processes as new designs come through. In this role, you will be the technical expert responsible for satellite mechanical integration and vibration testing, ensuring that the structure, payload, solar arrays, propulsion and thermal hardware come together as a flight-ready unit that survives launch. You will act as the primary technical contact for mechanical integration issues and drive improvements in build cycle time, test efficiency and build reliability, ensuring every spacecraft meets ICEYE’s high standards for reliability and mission success.
Key Responsibilities
Lead the mechanical integration of the satellite (structure, payload, solar arrays, propulsion, harness routing, thermal hardware), including torque control, bonding, alignment and mass properties measurements
Own vibration test campaigns end to end: test specification, fixtures, instrumentation, execution, data analysis and reporting, with test levels and FEM correlation defined together with Structures Engineering
Act as primary technical contact for mechanical integration issues, performing root cause analysis on nonconformances and coordinating with Mechanical/Structures Engineering to resolve anomalies
Survey, evaluate and select suppliers and test facilities for mechanical parts, MGSE and fixtures, including audits and first article inspections
Contribute to and improve AIT documentation, including mechanical integration procedures, test plans and as-built configuration records
Interface with Global AIT, Mechanical/Structures Engineering, QA and Launch teams to ensure alignment on product standards and lessons learned
Drive continuous improvement and automation in mechanical integration methods, test data processing and build cycle time
3+ years of hands-on experience in mechanical assembly, integration or testing of complex systems, preferably in aerospace or high-reliability hardware industries
Hands-on experience planning and executing vibration testing (sine, random, shock), including fixture design, accelerometer instrumentation and test data analysis
Solid understanding of spacecraft mechanical architecture: structures, fasteners and torque control, bonding, alignment, mass properties and thermal hardware
Experience writing and executing integration and test procedures under a quality and configuration management system (ISO 9001 / AS9100 or equivalent)
Experience handling non conformances and performing root cause analysis
Ability to read engineering drawings and use 3D CAD for fixture and MGSE design, including GD&T
Proficient English (written and spoken) for cross-functional collaboration
Experience with Atlassian Cloud tools (Jira, Confluence)
Track record of enabling design-for-testability (DFT) and design-for-manufacturing (DFM)
Lean and Six Sigma experience
Experience with supplier audits, first article inspections or vendor selection
Experience with FEM test correlation or launcher interface requirements (e.g. Falcon 9 rideshare, ECSS-E-ST-10-03)
Experience with thermal vacuum, acoustic or deployment testing with gravity offload
Lifting operations certification or experience with MGSE proof-load testing
Proficient Japanese (written and spoken)
A job that matters in a dynamic Defence Technology and Earth Observation environment with a scale-up approach.
An independent role with a supportive and diverse work environment.
Health insurance.
Time for self-development, research, training, conferences, or certification schemes.
Relocation support, where applicable (e.g., flight tickets, accommodation, relocation agency support).
Inspiring, collaborative offices and silent workspaces that enable you to focus.
At ICEYE, diversity is more than just a value — it's our greatest strength. We're dedicated to creating an inclusive environment where every voice is not only heard but celebrated. Diverse perspectives drive innovation and creativity, so we actively seek individuals from all backgrounds and experiences.
No matter your background, we encourage you to bring your authentic self to the team. Join us and be part of a workplace where differences are embraced and valued, because together, we're stronger.

ICEYE builds and operates the world’s largest synthetic aperture radar (SAR) satellite constellation to monitor the Earth continuously, day or night and in any weather. Its SAR satellites capture radar imagery that can see through clouds and darkness, giving customers in defence and intelligence, insurance, emergency management, and environmental monitoring a persistent view of wide areas. Images and analytics are delivered from a network of satellites and, increasingly, sovereign constellations that governments can operate themselves. ICEYE plans to scale up production toward about 100 satellites per year by 2028 and has pursued large funding rounds to expand capacity and sovereign delivery, aiming to grow its revenue and backlog while offering reliable, near-real-time Earth observation data.
