Job Description

In this role as a Staff Mechanical Engineer – Technical Lead, you'll be at the forefront of designing next-generation optical pluggable modules. You'll collaborate within a dynamic team of skilled engineers, fostering an innovative environment where your expertise shapes breakthrough solutions. Your work will involve hands-on engineering, from simulations to prototyping, ensuring products meet industry standards. You'll enjoy a supportive culture that emphasizes professional growth and knowledge sharing. Benefits include a competitive salary, flexible work arrangements, health and wellness programs, and opportunities for continuous learning. Join us to make a meaningful impact on global connectivity while being supported by a collaborative and forward-thinking team.

How You Will Contribute And What You Will Learn

Design and develop mechanical components for optical pluggable modules, focusing on thermal, structural, and manufacturability aspects.

  • Perform and supervise thermal simulations and finite element analysis (FEA) to optimize designs.
  • Collaborate with system integration teams to create innovative die interconnect solutions exceeding 140GHz bandwidth.
  • Create and review CAD models and detailed engineering drawings for precision manufacturing.
  • Conduct tolerance and stress analyses, along with thermal design validation testing (DVT).
  • Develop prototypes and facilitate the transition from design to production, minimizing redesign efforts.
  • Engage with suppliers and contract manufacturers to troubleshoot mechanical and integration challenges.
  • Author and review engineering change orders (ECOs), bill of materials (BOMs), and technical documentation.

Key Skills And Experience

Must-Have:

  • Bachelor’s or Master’s degree in Mechanical Engineering
  • 10+ years of experience in mechanical design, particularly with optical or telecom hardware
  • Strong expertise in thermal design, FEA, and CAD modeling (Creo preferred)
  • Proficiency in conducting die stress/strain simulations
  • Excellent communication and leadership skills

Nice-To-Have:

  • Experience with optical transceiver packaging (e.g., QSFP, OSFP)
  • Knowledge of compliance and shock/vibration testing for telecom applications
  • Familiarity with advanced substrate technologies like LTCC and HTCC
  • Experience in new product introduction (NPI) processes
  • Understanding of electrical and thermal regulatory compliance requirements
