Thermal Engineer

About the role

Arieca is looking for a Thermal Engineer to join our Hardware R&D team. The role involves assisting the market introduction of our thermal interface materials (TIM) through design and implementation of liquid cooling solutions for thermal test vehicles, as well as designing and implementing experiments to understand the thermo-mechanical properties of semiconductor interfaces.

Responsibilities

• Design and implement liquid cooling solutions for thermal test vehicles
• Design and implement experiments to test hypotheses on understanding the thermo-mechanical properties of semiconductor interfaces in packaged electronics (smartphones, laptops, GPUs)
• Collect data efficiently and create professional customer-facing documentation
• Develop processes and systems that work well within the constraints of a startup
• Engage with customers, external vendors, and ecosystem partners

Requirements

• Minimum of 1-3 years of experience working in industry or an academic research laboratory, with significant hands-on work on single phase liquid cooling solutions (implementation of cold plates, heaters, thermocouples, pumps, chillers, etc.)
• Experience with microcontrollers like Arduino and Raspberry Pi for real-time physical control and data collection/processing and system management
• Solid foundation in thermal science, including material characterization (e.g. ASTM D5470, thermal test vehicles)
• Familiarity with at least one thermomechanical simulation tool (Ansys, Autodesk Fusion, etc.)
• Experience with scientific programming in Python, Matlab, or C++
• Bachelor of Science or higher in Mechanical Engineering, Electrical Engineering, Mechatronics, or equivalent degrees
• Meticulous organizational skills, attention to detail, and pride in producing high-quality work

Qualifications

• Experience designing analog electrical circuits, semiconductor packages or substrates (flip-chip, BGA, LGA, etc.), or data acquisition systems
• Rapid prototyping and machine shop experience
• Experience in semiconductor industry, non-destructive testing or reliability engineering

Skills

• Expertise in scientific programming in Python, Matlab, or C++
• Significant skills designing GUIs in LabView

Benefits

Competitive salary and benefits including healthcare, flexible PTO, stock options, and 401(k) matching.
