Build custom test setups and instrumentation as needed

Perform detailed data analysis and translate results into engineering decisions

Document methods, results, and conclusions in clear technical reports

Evaluate electronic materials and assemblies under electrical, thermal, and environmental stress

Investigate degradation mechanisms such as dielectric breakdown, corrosion, delamination, and fatigue

Guide materials selection and design tradeoffs based on reliability risk

Design lifetime and robustness tests for electrowetting-based systems

Analyze failure mechanisms involving dielectrics, surfaces, interfaces, and working fluids

Collaborate with design engineers to improve stability, repeatability, and lifetime

Study fluid and emulsion stability, aging, contamination, and material compatibility

Design accelerated aging and chemical compatibility experiments

Work cross-functionally to mitigate chemistry-driven reliability risks

Develop reliability approaches for tightly coupled micro-scale electrical, mechanical, and chemical systems

Correlate accelerated tests to real-world operating conditions

Influence product architecture and operating envelopes based on reliability data

Present findings, risks, and recommendations directly to the CTO

Partner closely with product design and manufacturing engineering

Help translate reliability learnings into design rules and process controls

Rapidly understand Sangtera’s technology, materials stack, and operating regimes

Identify top reliability risks and unknowns

Design and begin executing a focused reliability test plan

Establish baseline lifetime and degradation behavior across key subsystems

Implement accelerated testing that correlates to real operating conditions

Drive design or process changes to address dominant failure modes

Identify, execute, and demonstrate a clear plan achieving at least 3 months of continuous operational lifetime under defined conditions

Deliver data-backed confidence in product robustness and remaining risks

Formalize reliability test methods suitable for future qualification and scale-up
