Confirmed on the employer's own hiring board on Oct 29, 2026. First seen by Alion on Oct 27, 2026.
Thermal Engineer - Full Time Job Opportunity
Who We Are:
Arieca is leading the commercialization of easy to deploy liquid metal embedded elastomer (LMEE) technologies, which enable unprecedented performance in applications across semiconductor, electronics, automotive, and healthcare industries. Our TIMbberTM product line targets leading semiconductor thermal interface material (TIM) challenges. As a CMU spin-out, venture-backed company, we are expanding our team to bring our lab innovations to market.
What We Need:
Arieca is looking for a Thermal Engineer who will join our Hardware R&D team to assist the successful market introduction of our thermal interface materials (TIM). Responsibilities include design and implementation of liquid cooling solutions for thermal test vehicles, in addition to designing and implementing experiments to test hypotheses on understanding the thermo-mechanical properties of semiconductor interfaces in packaged electronics (smartphones, laptops, GPUs). Strong organizational, analytical and communication skills are required, as we need to collect data efficiently and create professional customer facing documentation, while developing processes and systems that work well within the constraints of a startup. Engagement with customers, external vendors and ecosystem partners is possible.
You will be working with a team of highly motivated and ambitious individuals with a diverse background of exceptional scientific, entrepreneurial, and industrial experiences. This position offers competitive salary and benefits including healthcare, flexible PTO, stock options, and 401(k) matching.
Key Requirements:
- Minimum of 1-3 years of experience working in industry or an academic research laboratory, withs 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)
- Familiar with at least one thermomechanical simulation tool (Ansys, Autodesk Fusion, etc.).
- Experience with scientific programming in Python, Matlab, or C++. On the job, we will develop GUIs for DAQ systems, so expertise here is a bonus. Significant skills designing GUIs in LabView can substitute here.
- 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
Nice to have:
- 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, nondestructive testing or reliability engineering.
Arieca is committed to principles of diversity and inclusion, and encourages candidates to apply even if they do not exhibit all of the above-mentioned characteristics.
