Job description

We are looking for a junior engineer focused on power electronics and failure detection processes for renewable energy converters.

Position: Junior Diagnostic & Reliability Engineer – Renewable Power Systems

Work Model: Full-time, On-site (Laboratory-based)

About The Role

Join our hardware reliability team to uncover the root causes behind electrical and electronic anomalies in renewable energy conversion systems. In this role, you will bridge theoretical engineering and hands‑on laboratory investigation, examining everything from discrete board‑level components to high‑power converter stages to ensure our clean energy technology operates without disruption.

Key Contributions

• Lead diagnostic laboratory workflows to evaluate damaged power boards, passive/active components, and converter modules.
• Formulate scientific hypotheses explaining anomalies, validating your assumptions through controlled fault replication and bench testing.
• Operate standard instrumentation (digital storage oscilloscopes, precision DMMs, variable power supplies, curve tracers) to capture electrical signatures and transients.
• Analyze circuit schematics, operational telemetry logs, and part datasheets to trace failure propagation paths.
• Prepare structured technical documentation summarizing diagnostic steps, evidence gathered, underlying mechanisms, and corrective design proposals.
• Liaise with third‑party testing centers, external failure‑analysis labs, and component vendors when advanced materials analysis or vendor insight is needed.

Candidate Profile

• Academic background (B.Sc. / M.Sc.) in Electrical, Electronic, or Power Electronics Engineering.
• Prior exposure—via academic projects, university lab research, internships, or early career roles—to electronic hardware testing, diagnostics, or quality assurance.
• Working grasp of analog/digital circuitry, power devices, and schematic interpretation.
• Sound laboratory fundamentals: safe handling of high/low voltage setups, measurement instrumentation, and experimental protocol.
• Analytical curiosity: a passion for uncovering the underlying mechanism of a breakdown rather than merely replacing a damaged part.
• Professional fluency in English (capable of drafting technical summaries and discussing findings in cross‑border teams).
• Willingness to work on‑site, as the position relies directly on benchtop testing and physical hardware inspection.
