Package Reliability Engineer

Location: Aachen, Germany; hybrid

Company

hirify.global develops graphene photonic solutions that connect chips into high-throughput, low-delay, energy-efficient computing networks.

What you will do

• Own mission profiles and reliability targets, including operating conditions, FIT, MTBF, and lifetime allocation across package, interconnect, and device contributors.
• Assess package-level failure mechanisms across substrates, die attach, interconnects, solder joints, board attach, and optical or fiber interfaces.
• Define and execute thermal, mechanical, environmental, and board-level qualification plans using applicable industry and customer requirements.
• Lead technical collaboration with OSATs, substrate suppliers, and external laboratories, reviewing qualification evidence and reliability data.
• Drive root-cause investigations and failure analysis using X-ray, C-SAM, cross-sectioning, SEM/EDX, and related methods.
• Provide risk-based recommendations for design improvements, requalification, customer sampling, qualification milestones, and production release.

Requirements

• Master's degree or equivalent experience in Electrical Engineering, Microelectronics, Materials Science, Reliability Engineering, or a related field.
• 3–5+ years of experience evaluating semiconductor package construction and associated failure mechanisms.
• Understanding of high-speed I/O and RF reliability, including signal integrity, insertion loss, jitter, and eye closure over product lifetime.
• Experience with FIT and MTBF calculations, mission profiles, acceleration models, and measurable reliability targets.
• Knowledge of JEDEC, AEC-Q100/Q006, IPC, and IEC qualification standards.
• Strong failure analysis, cross-functional communication, ownership, adaptability, and startup-environment skills.
