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.
