Who We Are:

Advanced Cooling Technologies, Inc. (ACT) is a premier thermal solutions provider serving many diverse markets including Defense, Aerospace, High-Performance Computing, Power Electronics, Medical and HVAC industries.

We are at the forefront of advanced thermal management technologies, delivering high-performance cooling solutions for the world’s most demanding environments. Our innovative products support AI, HPC, and cloud infrastructure by ensuring reliable, energy-efficient thermal performance. As we continue to grow, we are seeking a talented and driven Product Development Engineer to join our team and contribute to the design and commercialization of next-generation thermal solutions, including air, liquid, and two-phase cooling systems.

ACT is strongly committed to our customers, employees, and our community. Innovation, Teamwork and Customer Care are our core values that drive the continuous growth of our company. Our skilled and dedicated staff is our strongest resource and the critical factor in our ongoing success.

Position summary:

As a Data Center Thermal Solutions Engineer, you will lead the design, analysis, prototyping, and testing of thermal products for data center applications. You will collaborate with manufacturing, marketing, and the customer’s engineering teams to develop innovative cooling solutions that meet performance, cost, and reliability goals.

Projects range from iterative improvements to existing designs to clean-sheet development and advanced performance testing. Product Development Engineers typically manage multiple programs simultaneously, offering broad exposure to the entire product development cycle. Working within a multidisciplinary team, including Electrical Engineers and Engineering Technicians, you will help bring complex thermal systems from concept to production. Candidates with a strong technical foundation and experience data center systems are especially well-suited for this role.

We will consider fully-remote for the right candidate, but will require on-site presence for initial training, and then at least quarterly on-site visits.

Responsibilities Include:

• Design and develop thermal management products (e.g., cold plates, heat exchangers, CDUs, air-to-liquid systems) from concept to production.
• Perform thermal and fluid simulations (CFD, FEA) to optimize performance and reliability.
• Perform structural analysis on support systems and pressure containing components (FEA)
• Conduct hands-on prototyping, testing, and validation of thermal systems under real-world conditions.
• Translate customer requirements into engineering specifications and product architectures.
• Manage customer experience through periodic status update meetings (PowerPoint presentations) and overall project management
• Collaborate with sales and marketing teams to generate proposals and marketing content to support business unit growth
• Generate detailed 3D CAD models, drawings, BOMs, and engineering documentation including test reports, work instructions, and operations and maintenance manuals.
• Support product lifecycle activities including DVT, EVT, and NPI launches.
• Collaborate with suppliers and internal teams to ensure manufacturability and cost effectiveness.
• Stay informed of emerging trends in data center cooling, industry standards, and thermal technologies.

The ideal candidate will possess the following qualities:

Initiative: Product Development engineers don't have a daily agenda given to them and are expected to take it upon themselves to work closely with customers, vendors and ACT personnel to fulfill projects goals and objectives.

Technical knowledge: We are looking for a candidate who has a strong real-world engineering background, coupled with hands-on skills and fabrication and testing capabilities.

Teamwork skills: As a member of the product development team, the ideal candidate must have the ability to give and receive encouragement and constructive criticism, communicate effectively, and work cooperatively with team members to achieve common goals.

Critical thinking skills: Customers and projects vary widely in Product Development, and the strategies and design approaches that worked for one program may be completely different for the next opportunity. Because of that, we need a curious individual who loves to dive in, experiment, and develop innovative solutions to new challenges.

Desire to grow: The ideal candidate wants to be the best at their job and is never content with "good enough". They set lofty goals and constantly seek to improve themselves and expand their professional knowledge and skillset. They desire to sharpen their engineering and project management skills and grow in leadership ability and responsibility.

• B.S. or M.S. in Mechanical Engineering or related (non-technical) engineering degree
• 3+ years of experience in thermal systems product development, preferably in electronics or data center cooling.
• Strong background in heat transfer, thermodynamics, and fluid dynamics.
• Experience with CFD tools (e.g., Ansys Fluent, Autodesk CFD, or similar).
• Proficient in 3D CAD (SolidWorks).
• Knowledge of thermal product manufacturing processes such as CNC machining, brazing, and sheet metal fabrication.
• Excellent problem-solving, communication, and project management skills.

Preferred Skills:

• Experience with two-phase cooling technologies (refrigerant, heat pipe, or vapor chamber-based systems).
• Familiarity with industry standards (ASHRAE TC 9.9, 90.4, OCP, etc.).
• Exposure to data center infrastructure and liquid cooling deployments.
• Familiarity with environmental regulations for use of refrigerants in cooling systems
