About the role
The role sits within Nokia's NI ON PSE HW&TE GX Syst HW & CentEng 5 department, working on NILightpath optical networking hardware. The team develops high-speed pluggable optical transceivers and compact networking products spanning 25G to 1.6T applications. This engineer owns thermal design, simulation, and optimization for form factors such as OSFP, OSFP-XD, QSFP-DD, QSFP112, QSFP56, and CFP, driving thermal architecture decisions across the product development lifecycle.
What you will do
- Own thermal design, simulation, and optimization for OSFP, OSFP-XD, QSFP-DD, QSFP112, QSFP56, CFP, and future form factors.
- Develop thermal solutions for modules supporting 25G to 1.6T applications, ensuring compliance with specifications.
- Collaborate with mechanical, signal integrity, optics, electronics, manufacturing, and reliability teams.
- Select and optimize thermal solutions such as heat spreaders, sinks, vapor chambers, and heat pipes.
- Understand and manage module-to-cage thermal interfaces and host-system cooling interactions.
- Perform thermal simulations using FloTHERM and other thermal analysis tools and optimize airflow paths, pressure drops, and component temperatures.
- Correlate simulation results with lab measurements and drive design improvements.
- Conduct thermal validation and testing, including thermal characterization, airflow analysis, and power dissipation testing.
Skills used in this role
What the employer is looking for
- B.E./B.Tech/M.E./M.Tech in Mechanical, Thermal, Aerospace Engineering, or related field.
- 3+ years of electronics cooling and thermal engineering experience.
- 2+ years of thermal design for pluggable optical modules (OSFP, QSFP-DD, CFP, SFP family).
- Strong understanding of thermal challenges in DSP/ASIC cooling, optical engines, and laser devices.
- Experience with FloTHERM and other thermal tools for thermal simulations and modeling.
- Ability to correlate simulation results with lab measurements and drive design improvements.
- Hands-on experience with thermal validation for optical transceivers or compact networking products.
- Proficiency in thermal validation tools and techniques, including thermocouples and IR imaging.
- Strong analytical skills, methodical approach, and excellent technical reporting abilities.
