About Ackcio
Ackcio builds wireless IoTmonitoring systems for geotechnical and civil infrastructure applications –deployed on construction sites, tunnels, slopes, and structures worldwide. Ourhardware products include the BEAM platform (Digital, Analogue, and VibratingWire Nodes), TM-L Tiltmeter, and GeoArray MEMS Inclinometer Array. As we scaleglobally, maintaining hardware quality, driving continuous improvement, andmanaging our contract manufacturer relationship are critical to our success.
About the Role
We are hiring a HardwareEngineer to own the full hardware quality loop – from RMA diagnostics andhands-on rework, through root cause analysis, to driving design improvementsthat feed back into production. This is not a pure bench technician role and nota pure design role. It sits squarely in the middle: you diagnose real-worldfailures, identify systemic issues, update schematics and BOMs, and work withour contract manufacturer (CM) to ensure changes land in production.
You will be the single point ofownership for returned hardware, and the bridge between field failures anddesign improvements. You need to be equally comfortable with a soldering ironand with Altium (or equivalent), and you must be able to communicate technicalfindings clearly – both internally to engineering and externally to our CM.
If you have worked in afast-moving, small-team environment where you had to figure things out withouta playbook – and you are energised by that kind of ownership – this role is foryou.
What You Will Do
RMA Diagnostics & Root Cause Analysis
- Receive, log, and triage returned devices fromcustomers globally
- Execute structured diagnostic routines to identify rootcause – distinguishing hardware faults, firmware issues, handling damage, andenvironmental failures
- Document all findings: failure mode, test results,probable root cause, and recommended disposition
- Identify recurring failure patterns across RMA batchesand escalate systemic issues
Hands-On Rework & Repair
- Perform component-level rework to a high standard: SMDsoldering, module replacement, connector repair
- Re-flash firmware on repaired units and validateagainst test criteria before return or redeployment
- Maintain a clean, traceable repair log for each unitprocessed
- Operate and improve existing test jigs for BEAM Nodesand sensor products
Design Improvement & Engineering Change
- Translate RMA findings into actionable improvementplans with clear problem statements, proposed fixes, and expected impact
- Update schematics to reflect approved design changes
- Update Bills of Materials (BOMs) to reflect componentchanges, alternates, or obsolescence replacements
- Work with the engineering team to review and validateproposed changes before release to production
Contract Manufacturer (CM) Interface
- Prepare and deliver structured reports to the CM ondesign changes, BOM updates, and quality findings
- Review CM build reports, first-article inspectionresults, and production yield data
- Coordinate with CM on engineering change orders (ECOs)and ensure changes are implemented correctly
- Support new product introduction (NPI) activities atthe CM as needed
Quality & Process
- Support pre-shipment QC checks and maintain the QCchecklist for new product releases
- Recommend and implement improvements to testprocedures, rework SOPs, and QC gates
- Maintain jig calibration records and flag anomalies
What We Are Looking For
Must Have
- Degree in Electrical or Electronic Engineering (orclosely related discipline)
- 3–5 years of hands-on experience in electronicsdiagnostics, repair, or test – ideally in a production, RMA, or NPI environment
- Strong SMD rework skills – fine-pitch components; BGArework experience is a plus
- Proficient with bench equipment: oscilloscope,multimeter, logic analyser, soldering station
- Ability to read, interpret, and update schematics andPCB layouts independently
- Experience with EDA tools (Altium Designerpreferred; KiCad, OrCAD, or Eagle acceptable) – specifically for schematicedits, BOM management, and design review
- Systematic fault-finding approach – you work through adiagnostic process, not just replace parts until something works
- Clear, structured documentation and reporting habits –your reports should be ready to send to a CM without editing
- Self-directed and proactive – you do not wait to betold what to fix next
Good to Have
- Prior experience interfacing with a contractmanufacturer (ECOs, build reports, yield analysis)
- Exposure to IoT or wireless hardware (LoRa, BLE, GPSmodules, embedded MCUs)
- Experience with UART, JTAG, or SWD debug interfaces
- Familiarity with DFM/DFA principles
- Experience in a startup or small-team environment whereyou wore multiple hats
- Experience writing or refining test procedures and workinstructions
How to Apply
- Send your CV and a short notedescribing:
- The most complex hardware fault you have diagnosed andresolved
- A design or process improvement you drove based onfailure analysis
- Send to: hr@ackcio.com
