Mechanical Design Engineer

The Role
 
We are seeking a highly motivated Senior Mechanical Engineer, Thermal Interface Material Integration to serve as the primary technical partner for our customers as they evaluate and adopt our high-performance thermal interface material (TIM) products. This role is ideal for an engineer who thrives at the intersection of customer engagement, problem-solving, and product performance validation. You will be responsible for leading early- to mid-stage customer interactions, capturing and translating requirements into actionable technical work, and ensuring that customers have the data, samples, and support they need to successfully integrate and qualify our TIM in their advanced semiconductor packaging applications. This position offers the opportunity to work closely with hyperscalers, ODMs, and OSATs, and to influence the adoption of cutting-edge thermal solutions in next-generation AI and data center systems.
 
Join us to solve one of the most critical challenges facing the Semiconductor and Electronics Industry – thermal management!

Your Responsibilities

- Create CAD models, assembly drawings, and fabrication documentation for integrating our liquid-metal based thermal interface materials into customer-specific electronic packages.

- Build, instrument, and test package and assembly mockups to demonstrate design feasibility, including mechanical and reliability testing.

- Run thermal and mechanical test setups, reduce and analyze the resulting data, and summarize findings in clear internal reports.

- Coordinate part fabrication with internal shop resources and external vendors to keep project schedules on track.

- Support senior engineers in customer technical engagements – preparing sample builds, test data packages, and supporting material for application notes and design guides.

- Help capture and document customer technical requirements, including geometric, load, assembly, and environmental constraints, thermal budgets, and reliability standards.

- Support the R&D team in continuous improvement of system and product performance.

- Maintain organized design files, test records, and documentation to support customer qualification processes.

Your Skills and Expertise

- Bachelor's or Master's degree in Mechanical Engineering or a closely related field.

- 0–3 years of professional experience; relevant internship, co-op, or hands-on project experience will be considered.

- Proficiency with CAD modeling and drafting (SolidWorks, Creo, or similar) and a working knowledge of GD&T.

- Hands-on prototyping and lab skills, with comfort building fixtures, running tests, and troubleshooting setups.

- Solid grounding in heat transfer and mechanics fundamentals; interest in electronics packaging and thermal design.

- Strong data analysis and technical writing skills (Excel, Python, or MATLAB a plus).

- Excellent communication skills and the willingness to ask questions, take direction, and learn quickly in a fast-moving environment.

- Exposure to semiconductor packaging, electronics assembly, thermal interface materials, or reliability testing (TCT, HTS, uHAST) is a plus.

- Familiarity with FEA modeling is a plus.

- Up to 10% travel to customer or vendor sites is expected.
