Job description

You will be the technical process owner for the propulsion AIT programme, responsible for turning qualification requirements and engineering intent into a complete library of test procedures, test plans, and assembly instructions.

You will work alongside the Propulsion Design and Test Engineers, report into the Lead AIT Engineer, and partner closely with the Technical Programme Manager to ensure delivery. You will own the procedural and logistical backbone of the propulsion qualification campaign - from first-article assembly through to system-level acceptance testing.

This is a mid-level role for someone who can translate system knowledge into rigorous, operator-ready documentation, and then execute those procedures hands-on. Qualification strategy and test logic are defined by the Technical Programme Manager; your role is to take that framework and build the detailed technical processes that make it executable - and then run them.

Key Responsibilities

• Own the writing, review, and maintenance of all assembly instructions, work instructions, and build procedures - from component level through to integrated module on the propulsion system.
• Write and own test plans and test procedures for propulsion campaigns, including pressure test, proof test, leak test, functional flow test, and performance characterisation.
• Maintain the AIT schedule for the propulsion system, interfacing with test facilities and ensuring all GSE is available for each test in the plan.
• Ensure that all equipment is kept calibrated.
• Develop and maintain hazardous operations procedures for all pressurised system activities, in line with safety requirements defined for the programme.
• Write propellant handling and loading procedures.
• Execute test and assembly procedures hands-on, operating test rigs and instrumentation and recording results to programme traceability standards.
• Maintain the propulsion procedure library - version control, review cycles, and configuration management of all procedural documents.
• Support integration of the propulsion system into the satellite structure, contributing assembly procedures for the integration sequence.
• Manage non-conformances on propulsion hardware - raising NCRs, supporting dispositions with the propulsion design team, and updating procedures where needed.
• Perform goods in inspection of incoming components, against purchase orders, drawings, and certificates of conformance.
• Coordinate with technicians ensuring tasks are understood and completed in line with the schedule.
• Support environmental test campaigns involving the propulsion system, contributing test procedures and witnessing campaigns.
• Support satellite AIT activities.

Fundamental Requirements

• 3+ years' experience writing test procedures, assembly instructions, or work instructions for mechanical, fluidic, or propulsion hardware in a flight or high-reliability environment.
• Practical hands-on experience executing the procedures you write - comfortable on the bench as well as at the desk.
• Experience with pressurised systems - sufficient to write safe, compliant procedures and execute them competently.
• Ability to read and interpret engineering drawings, schematics, and system documentation to produce accurate procedural content.
• Good documentation discipline - understands version control, review processes, and what traceability means in a flight programme context.
• ESD-aware working practices and understanding of contamination control requirements.
• Strong safety mindset around pressurised and hazardous operations.

Nice-to-haves

• Experience in a space, aerospace, defence, or other high-reliability industry environment.
• Familiarity with pressure testing methods (proof, leak, burst, flow) and the standards that govern them.
• Experience with vacuum chamber operation and maintenance.
• Experience with electric propulsion systems or vacuum test environments.
• Familiarity with ECSS standards or equivalent quality and workmanship frameworks.
• Experience handling xenon or other inert propellants, including loading and facility operations.
• Background in mechanical AIT as well as propulsion - comfortable contributing to wider satellite integration activities.
