Job description

As our Electronics Technician, you live on the bench and in the cleanroom, keeping the flight and ground support electronics of our Rendezvous and Proximity Operations (RPO) capable spacecraft alive through assembly, integration and test.

You will spend your time reworking and repairing populated assemblies, manufacturing and testing flight and EGSE harnesses, running unit and subsystem test campaigns, and keeping the electronics lab in a state where anyone can walk up to a bench and trust what is on it. You will work alongside our electronics designers bringing up boards, standing up test setups and fault‑finding to component level and feed manufacturability and testability input back before designs are committed. This is an in‑office role at our Sydney (Botany) facility.

In this role, you own outcomes from end to end, including:

• Rework & Repair – Repair, rework and modify populated electronic assemblies to flight standard, including fine‑pitch surface mount and through‑hole work, conformal coating, staking and cleaning. This is the heart of the role.
• Harness Manufacture – Manufacture, modify and test flight and EGSE wiring harnesses – cut, crimp, connector assembly, lacing, backshells and potting, through to continuity and insulation resistance verification.
• Electronics Lab Ownership – Own the electronics lab end to end: tooling, consumables, calibration status, ESD compliance and bench discipline. The lab works because you make it work.
• Test Execution – Run subsystem and unit level test campaigns. Set up and operate test equipment, work to written procedures, capture data and record results with full traceability.
• Bring‑Up & Fault‑Finding – Support in‑house electronics development through prototype board bring‑up, debugging of test setups, and methodical fault‑finding to component level alongside the design team.
• Flight Hardware Integration – As part of the AIT team, perform assembly and integration on flight hardware under ESD, FOD and cleanroom controlled conditions, and support environmental test campaigns including vibration, thermal vacuum and EMC including instrumenting the test article and standing up ground support equipment.
• Documentation & Nonconformance – Write and red‑line work instructions, test procedures and as‑built records to a standard presentable to external partners and regulators. Raise and help close non‑conformances.
• Design Feedback – Provide practical feedback on manufacturability, testability, maintainability and serviceability, early enough to change the outcome.

There is room to grow. If you have the interest, you will be supported on the design of support electronics in house such as break‑out boards, test jigs, interface adapters and harness test boxes from requirement through schematic capture, layout and fabrication, with guidance and mentoring from the electronics design team. That is an opportunity in this role, not a prerequisite for it.

About You

You'll thrive in this role if you bring:

A technician's hands – precise, repeatable workmanship on hardware that has to survive launch and then work for years with nobody able to reach it.

Methodical fault‑finding – following the evidence to the failing component rather than swapping parts and hoping.

Ownership of the space around you – a lab that is calibrated, stocked, ESD‑safe and ready, because you keep it that way.

The judgement to stop – speaking up when something doesn't look right, before it becomes a non‑conformance on flight hardware.

Proven experience:

• Trade qualification, diploma, or strong exhibited experience in electronics, avionics, mechatronics or a related technical discipline
• 3+ years hands‑on experience building, testing or maintaining electronic hardware in aerospace, defence, medical, motorsport or another high‑reliability field
• Demonstrated soldering and rework skill on fine‑pitch surface mount and through‑hole assemblies
• Direct experience manufacturing and testing wiring harnesses and cable assemblies
• Confident with lab instrumentation – oscilloscopes, multimeters, bench supplies, logic analysers – and able to read schematics and wiring diagrams to fault‑find independently
• Disciplined approach to documentation and traceability, including working to written procedures in a controlled environment
• Experience maintaining a lab, workshop or bench environment – tooling, consumables, calibration status and ESD control
• Working effectively both independently and in teams

Bonus experience:

• IPC J‑STD‑001 and/or IPC‑A‑610 certification, or an ECSS/NASA equivalent space soldering qualification
• Designing simple PCBs and assemblies in KiCad, Altium or similar – test jigs, break‑out boards, interface adapters – even at a non‑professional level
• Experience with spacecraft or other flight hardware assembly, integration and test
• Experience supporting environmental test campaigns – vibration, thermal vacuum, EMC
• Familiarity with embedded interfaces such as CAN, RS‑422/485, I2C and SPI
• Basic scripting for test automation and data capture
• Inspection techniques such as microscopy or X‑ray of PCB assemblies
• Experience within start up, scale up or small companies

Benefits

You won't get rich quickly. But you'll get:

• Competitive salary – Fair pay for hard work. Commensurate with experience and the impact you'll have.
• Meaningful equity (ESOP) – Real ownership stake. Stock options that matter because you're joining early enough for them to matter. If we win, you win.
• Actual leave – Annual leave plus personal/sick days. Because even warriors need to recover.
• Public holidays – All of them.
• And freedom. Real freedom to build, decide, and move without waiting for permission. That's not a benefit you’ll find in a package description, but it's worth more than most perks on this list.
