Mechanical AIT Engineer

Mechanical AIT Engineer

EnduroSat

Sofia, Bulgaria

What is the role?

As a Mechanical AIT Engineer, you turn engineering intent into flight-ready hardware with full traceability, reliability, and speed. You will be at the heart of our production floor, transforming engineering drawings into fully functional satellites.

Some of your daily tasks will include:

• Build flight hardware: assemble and integrate structures, mechanisms, propulsion modules, payloads, and harnesses on our platforms per drawings, BOMs, and work instructions;
• Own integration: perform precision torquing/locking, bonding and staking, adhesive/RTV application, connector mating, harness dressing, and cleanliness controls;
• Guard quality: execute incoming, in-process, and final inspections; enforce ESD/FOD and cleanroom protocols; ensure configuration control and full part traceability;
• Document precisely: create and maintain travelers, detailed work instructions, torque logs, build records, and nonconformance reports (NCR/MRB);
• Test for flight: prepare MGSE/fixtures and support environmental test campaigns (vibration, shock, TVAC); run fit checks and post-test inspections; contribute to TRR/PRR/ATRs;
• Problem-solve fast: diagnose integration issues, drive root-cause analysis, and feed DFM/DFA improvements back to design;
• Improve continuously: implement 5S, lean practices, and data-driven improvements to reduce cycle time and increase first-pass yield;
• Enable the team: collaborate daily with design, electronics, RF, production, and test to deliver on schedule and to spec.

What do we look for?

• Degree in Mechanical, Aerospace, or related engineering;
• 5+ years of hands-on assembly/integration of high-reliability hardware (space, aerospace, defense, medical, or similar);
• Strong command of mechanical systems and good understanding of electrical interfaces; fluent in reading CAD, GD&T, and schematics;
• Proven proficiency with precision tools (torque tools, calipers, micrometers) and workmanship to ECSS/IPC/NASA standards;
• Experience in cleanroom environments with strict ESD, FOD, and contamination control;
• Excellent troubleshooting, root-cause analysis, and clear technical documentation in English.

How to Stand Out:

• Direct AIT experience on nano/microsatellites or spacecraft subsystems;
• Familiarity with ECSS/NASA workmanship standards and space-quality assurance;
• Hands-on with environmental testing (TVAC, vibration, shock) and test procedure authoring;
• Experience with ERP/PLM/MES and digital travelers; JIRA/Confluence is a plus;
• Lean/Six Sigma exposure; demonstrable continuous improvement results;
• Experience with propulsion integration, precision mechanisms, opto-mechanics, or harness assembly (IPC/WHMA-A-620);
• Data skills for test analysis (e.g., Python/Matlab) are welcome.
