MQE Product Engineer

About Doodle Labs

Doodle Labs builds the connectivity backbone of the autonomous systems revolution — resilient wireless mesh networks that let drones, robots, and unmanned platforms operate reliably in the world's most demanding environments. We sit at the intersection of defense, robotics, and next-generation autonomy, powering the machines that are changing how militaries, first responders, and industries operate in the field. Our core purpose is simple: connect anyone and anything, at any time, in any place.

For over 25 years, our team has been at the forefront of mesh networking, partnering with leading defense programs, robotics manufacturers, and system integrators worldwide. The work here doesn't sit in a slide deck — it ends up in the field, in the hands of people for whom failure isn't an option.

About the Job

The MQE Product Engineer is the product quality specialist within the MQE team. Reporting to the MQE Manager, you will work alongside the Process Engineer and Test Engineer to support the Contract Manufacturing (CM) Manager in improving the manufacturing quality of our products.

While the Process Engineer improves how products are built and the Test Engineer maintains the test systems, the Product Engineer safeguards the product itself – its quality acceptance, defect disposition through the Material Review Board (MRB), production automation, cost of quality, and full traceability from incoming material to finished goods.

In close support of the CM Manager at our contract manufacturer in Batam, Indonesia, this role turns quality data into action: dispositioning non-conforming product, driving defect reduction with the Process and Test Engineers, and building the automation and tracking systems that make product quality visible and controllable.

What You'll Do

1. Support the CM Manager on

Product Manufacturing Quality Engineering

• Coordinate

with the CM Manager, providing supporting Production Engineering related task.

• Define

product acceptance criteria, Production quality specifications for each radio model.

• Monitor

product-level quality metrics – SMT defect rate (PPM), MI/functional pass yield, and outgoing quality (OQC/ORT) – and escalate risks to the MQE Manager and CM Manager.

• Supporting

and reviewing Product transferring from design completion to Operation, engineering changes (ECN/ECO), and alternate parts.

2. Support the Material Review

Board (MRB) Process

• Serve

as the Doodle Labs technical representative on the MRB at the contract manufacturer.

• Disposition

non-conforming material and products – use-as-is, rework, repair, scrap, or return-to-vendor (RTV) – with documented engineering justification.

• Lead

containment and purge actions for suspect lots and verify rework effectiveness before release.

• Maintain

MRB records and disposition turnaround time (TAT) metrics, and drive supplier corrective actions (SCAR) for material-related defects.

3. Reduce Production Defects

with the MQE Team

• Lead

product-level root-cause analysis for production defects and customer returns using 8D, 5-Why, and fishbone methodologies.

• Partner

with the Process Engineer on process-related corrective actions and with the Test Engineer on test escape and test coverage gaps.

• Drive

corrective and preventive actions (CAPA) to closure with verified effectiveness, and feed lessons learned into design-for-manufacturing (DFM) and design-for-test (DFT) reviews.

• Analyze

test yield data with the Test Engineer to identify top failure modes and prioritize defect reduction projects.

4. Manage Cost of Quality

(CoQ)

• Establish

and track Cost of Quality: scrap, rework, retest, MRB holding, warranty returns, and inspection costs.

• Prioritize

improvement projects by CoQ impact and report monthly savings to the MQE Manager and CM Manager.

• Reduce

rework loops and material waste through poka-yoke and upstream defect prevention with the Process Engineer.

5. Establish Production

Tracking from Material to Finished Goods

• Implement

end-to-end traceability: incoming material lots → PCBA serial numbers → sub-assembly → finished goods → shipment.

• Define

serialisation, labelling, and barcode/QR scanning requirements at each production stage with the contract manufacturer.

• Build

WIP tracking visibility so any unit can be located and its build history, test results, and material lots retrieved on demand.

• Enable

rapid lot isolation for quality alerts, recalls, and engineering change cut-in tracking.

6. Deliver Key Milestones

• First Month: Complete product quality baseline for one high-volume

model – defect Pareto, test yield, CoQ snapshot, and traceability gaps – documented in English and reviewed with the MQE Manager and CM Manager.

• First Three Months: Collaborate with CM manager to Stand up a

functioning MRB cadence with disposition Turn Around Time (TAT) tracking; propose the material-to-FG production tracking plan and first automation project with ROI.

• First Six Months: Deliver serial-number-level traceability for at least

one product line.

Who You Are

• Proven

experience in product engineering, manufacturing quality engineering, or a related role for electronic products, preferably with contract manufacturers.

• Experience

supporting or leading MRB: non-conforming material disposition, containment, rework verification, and supplier corrective actions (SCAR).

• Skilled

in structured problem-solving: 8D, CAPA, 5-Why, and fishbone analysis.

• Exposure

to production automation for electronics: automated data capture, vision/AOI data utilisation, barcode/RFID scanning, or MES integration.

• Experience

implementing traceability or production tracking systems (MES, ERP shop-floor modules, or serial number tracking) from material to finished goods.

• Experience

establishing quality metrics (PPM, FPY, yield) and Cost of Quality tracking.

• Strong

analytical skills with data-driven decision-making; comfortable with Excel-based analysis, dashboards, and workflow automation tools.

• A

team player who thrives in a matrixed setup – reporting to an MQE Manager while supporting a CM Manager and collaborating daily with Process and Test Engineers.

• Knowledge

of radio or RF product manufacturing and IPC-A-610 acceptance criteria is a strong advantage.

Required

Qualifications

• Education:

Degree in Electrical/Electronic Engineering, Manufacturing Engineering, or a related field.

• Experience:

Minimum of 3–5 years in product engineering, manufacturing quality, or a related engineering role for electronic products.

• Language:

Proficient in English (written and spoken); Bahasa Indonesia is an advantage for on-site collaboration in Batam.
