What are the responsibilities and job description for the Senior Thermal Engineer position at 3D Architech?
About 3D Architech:
3D Architech is pioneering next-generation metal manufacturing infrastructures that push the boundaries of design at the unprecedented scale – 10 micron or lower. Our proprietary gel‑enabled metal manufacturing platform enables geometries, thermal performance, and materials combinations that are not achievable with conventional additive or subtractive processes.
Our operation across the USA, Japan, and Taiwan, bridging advanced materials R&D with scalable manufacturing for thermal management applications. As we expand our R&D operations in the US, we’re seeking talented engineers to drive our manufacturing technology and the development of application-specific products for cooling devices.
Role Overview:
In this role, you will lead the development of advanced cooling devices using our proprietary gel-enabled metal manufacturing technology. You will work closely with a multidisciplinary team to address complex technical challenges and scale up our innovative solutions from R&D to manufacturing.
Key Responsibilities:
- Lead the design and evaluation of advanced cooling devices that exploit three‑dimensionally engineered metal architectures with fine geometric control at the 10 micron scale
- Identify technical challenges from a first-principles approach and develop hypothesis-driven solutions that integrate thermal modeling, calculations, and experimental validation
- Collaborate with external partners and establish strategic alliances to align technical requirements, translate application needs into product designs, and support data-driven technical proposals and reviews
- Establish thermal evaluation frameworks, including experimental setups and correlated simulation models, to ensure consistency between design intent, testing, and results
- Drive cross-functional technical discussions and mentoring, working with other thermal engineers and materials engineers to strengthen evaluation methodologies, design guidelines, and internal technical standards
- Stay abreast of emerging trends in advanced materials, manufacturing, thermal engineering, and data centers
Required Qualifications:
- Proven experience leading R&D teams in thermal engineering, fluid mechanics, product development, or closely related fields.
- Demonstrated ability to drive technology development in environments with high uncertainty and ambitious timelines
- Strong problem-solving skills with a first-principles approach
- Hands‑on strength in at least one of the following areas is required: (1) thermal evaluation and measurement systems including experimental setup and data interpretation, (2) modeling and numerical simulation for thermal and fluid systems, with experience in data processing, model verification, and validation, or (3) product development of cooling or thermal management hardware
- Master’s or Ph.D. in Thermal Engineering, Mechanical Engineering, Chemical Engineering, or a related discipline
- Proficiency in standard PC tools (Word, Excel, PowerPoint) for technical analysis, documentation, and communication
Preferred Qualifications:
- Experience designing and evaluating high heat‑flux cooling technologies, including cold plates, liquid cooling systems, and two‑phase cooling approaches
- Strong experience driving final design decisions efficiently using quantitative engineering approaches such as Design of Experiment (DoE) and optimization methods, with the ability to balance thermal performance and pressure drop
- Hands‑on experience with CFD tools such as SolidWorks Flow Simulation, ANSYS (Fluent, Icepak, CFX), COMSOL, OpenFOAM, or an equivalent technical skillset
- Experience handling complex geometries, including lattice or porous structures, with skills in parametric or mathematical geometry definition using tools such as SolidWorks, nTop (nTopology), or similar software
- Experience managing and leveraging large volumes of simulation results to accelerate subsequent design iterations and enable data‑driven thermal or cooling design decisions
- Experience in customer‑facing technical roles
Work Schedule and Compensation:
- Working Hours: Standard business hours with flexibility available.
- Occasional domestic and international travel
Benefits:
- Medical and dental insurance coverage
- Paid leave, maternity/paternity leave, and caregiving leave
