Position Overview

We are seeking a highly motivated Thermal Engineer to join our Front-End I/O Active Thermal Solutions team. The role focuses on developing and optimizing active thermal management solutions for high‑speed interconnect systems. The successful candidate will collaborate with customers to define boundary conditions, perform thermal simulations, validate designs through lab testing, and deliver optimized, production‑ready thermal solutions that meet performance, reliability, and manufacturability requirements.

Key Responsibilities

- Engage directly with customers to gather thermal boundary conditions, system‑level constraints, and performance requirements.
- Translate customer needs into actionable simulation and test plans.
- Develop and execute thermal models using CFD tools such as ANSYS Icepak or FloTHERM.
- Analyze airflow, temperature distribution, and heat dissipation in high‑density front‑end I/O environments.
- Perform sensitivity and optimization studies to meet design goals.
- Plan and conduct thermal testing and validation in collaboration with lab teams.
- Correlate experimental data with simulation results to refine and validate models.
- Identify and troubleshoot thermal design issues through root‑cause analysis.
- Optimize designs based on results to balance performance, cost, and manufacturability.
- Prepare detailed technical reports summarizing analysis, findings, and recommendations.
- Present results and solutions to customers and cross‑functional teams.

Qualifications





- Bachelor's or Master’s degree in Mechanical Engineering, Thermal Engineering, or a related field.
- 3+ years of experience in thermal design or analysis for electronic systems or interconnect hardware.
- Proficiency with CFD tools (ANSYS Icepak, FloTHERM, or equivalent).
- Experience with thermal instrumentation and data acquisition (thermocouples, IR cameras, etc.).
- Familiarity with CAD software such as SolidWorks or Creo.
- Strong understanding of heat transfer, fluid dynamics, and electronic packaging.
- Excellent problem‑solving and analytical skills.
- Strong communication and presentation abilities for customer interaction.
- Ability to manage multiple projects in a fast‑paced environment.

Preferred Qualifications

- Experience developing thermal solutions for high‑speed connectors, modules, or front‑panel I/O systems.
- Background in active cooling technologies (fans, blowers, heat pipes, vapor chambers, etc.).
- Understanding of electrical and mechanical design trade‑offs in system integration.
- Experience with Design of Experiments (DOE) or statistical optimization methods.

Benefits

- Comprehensive health, dental, vision, and travel insurance coverage.
- Health Care Spending Account for health‑related expenses.
- Pension plan.
- Progressive incentive plans.
- Opportunities for professional growth and development.
- Company recreation club with events and activities.
