About the Job

Requirements

  • Currently pursuing a Bachelor of Science or Master of Science in Mechanical Engineering or a related field.
  • Have coursework in Engineering Drawing, Manufacturing Processes, Thermodynamics and Heat Transfer, Engineering Mechanics, Strength of Materials, Design of Machine Elements, and Computational Design.
  • Have programming proficiency in Python or a similar language for scripting, data processing, and automation.
  • Have familiarity with computer-aided design tools such as SolidWorks or Creo.
  • Have hands-on prototyping experience through coursework, capstone projects, research labs, or personal projects; experience building, iterating, and validating physical assemblies is strongly valued.
  • Have the capacity to comply with federally mandated requirements of U.S. export control laws.

Responsibilities

  • Build tools to automate creation of substrate and package drawings from package design data, reducing manual computer-aided design and drafting effort.
  • Develop automated geometric dimensioning and tolerancing sanity checks to catch common drawing errors before release, including missing or inconsistent callouts, datum scheme issues, and tolerance conflicts.
  • Work with packaging, substrate design, and system engineers to capture drawing requirements, templates, and conventions, and turn them into repeatable workflows.
  • Validate tools against existing released drawings and iterate based on feedback from engineers using them.
  • Plan and execute physical design of experiments, including test setup, measurement, and data analysis, to build fundamental understanding of coupled thermal-structural-optical physics.

Desired Qualifications

  • Have exposure to geometric dimensioning and tolerancing and tolerance analysis concepts, including ASME Y14.5.
  • Have internships, capstone, thesis, or research project experience involving precision mechanical assembly, optical systems, or microelectronics packaging.
  • Have experience using artificial intelligence or machine learning tools or large language models to build design automation workflows, such as automating tolerance analysis, computer-aided design scripting, failure mode and effects analysis generation, or simulation post-processing.

About the Company

Lightmatter

Photonic computing hardware for AI acceleration

Lightmatter develops photonic computing hardware that accelerates AI workloads using light-based processors. Its photonic supercomputers run AI tasks faster and use far less energy (about 10x faster and 90% less energy) than traditional electronic systems. The company differentiates itself by focusing on electro-photonic systems and practical AI acceleration for AI and autonomous vehicle workloads, working with universities and selling hardware, software licenses, and partnerships. Its goal is to bring scalable photonic computing to market so AI and self-driving applications can run faster, more efficiently, and at larger scale.
