Requirements
  • Bachelor of Science in Mechanical Engineering from an accredited college or university. Advanced degree preferred.
  • Minimum of eight or more years of experience in mechanical and thermal engineering design and analysis with strong emphasis on heat transfer, fluids, and structural analysis.
Responsibilities
  • Develop new thermal mechanical technologies by researching and developing concepts, initial prototypes, performing functional and reliability tests, and transferring of technology to high volume production.
  • Perform analysis to determine if specifications are realistic and estimate risk exposure: thermal dynamics, computational fluid dynamics (CFD), thermal / mechanical finite element analysis (FEA), mean time between failure (MTBF) and failure modes and effect analysis (FMEA), or other mathematical models.
  • Participate or manage in all development phases of assigned projects, including requirement definition, design, test, integration, deployment and support.
  • Ability to develop and maintain project requirements, specifications, detailed plans, budgets, and ROI.
  • Track the progression of the projects to insure on-time completion and delivery while adhering to the product development processes.
  • Research and verify the performance and reliability of new vendor components.
  • Work cross functionally with electrical, software, vision, LAB technicians locally, in Germany and Switzerland, and with remote satellite centers in Malaysia, Korea and Taiwan.
  • Interface directly with operations, sales and customers as well as other Cohu Businesses as required.
  • Other duties as assigned.

Cohu provides test and inspection equipment for semiconductors, including test and inspection handlers, MEMS test modules, test contactors, thermal sub-systems, and automated test equipment. These capital instruments are designed, built, and sold to semiconductor manufacturers and test subcontractors, with services and support contracts generating recurring revenue. Cohu differentiates itself through an integrated portfolio that spans multiple test stages—handling, MEMS testing, contactors, and thermal subsystems—paired with a global service footprint. Its goal is to help customers reliably test and validate semiconductor devices across automotive, consumer, industrial, and medical applications to improve quality and yield.

Simplify's Take

What believers are saying

  • AI data center and HPC demand drive 57% order growth and a $80–100M HPC revenue outlook for 2026.
  • A multi-year $100M win with a leading European semiconductor manufacturer anchors Krypton platform adoption in automotive and industrial markets.
  • $260M in convertible notes and $489M in cash fund Eclipse ramp and capture of the expanding semiconductor equipment cycle through 2026.

What critics are saying

  • Eclipse supply chain ramp-up is already pushing operating expenses to $55M and compressing gross margins into the mid-40% range by year-end 2026.
  • The $260M convertible notes mature in 2030 and create a refinancing or cash repayment cliff if the semiconductor cycle turns down before then.
  • Krypton and NEON platform adoption depend on sustained AI capex; a 30–40% hyperscaler spending pullback would erase Cohu’s primary growth driver and force margin compression.

What makes Cohu unique

  • Cohu’s Krypton inspection platform delivers 30% higher throughput via racetrack architecture and NV-Core vision technology.
  • The NEON HBM inspection platform targets a $750M computing opportunity with 80% revenue growth forecast in 2026.
  • Cohu’s acquisition of Tignis embeds AI/ML process control and analytics directly into its test and inspection equipment stack.
