Engineer Hardware for the Next Generation of Space Missions
What if your next engineering challenge was something that had never been built before?
At Advanced Cooling Technologies (ACT), our Space Systems engineers work on real spacecraft programs—from early-stage concepts and new commercial platforms to scientific missions and some of the most ambitious programs in the space industry.
We work with NASA, established aerospace organizations, and innovative commercial space companies developing the next generation of satellites, spacecraft, instruments, and space infrastructure.
We're looking for an experienced Space Systems Senior Engineer who wants more than a narrowly defined engineering role. Here, you'll have the opportunity to take ownership of challenging programs, solve multidisciplinary problems, work directly with customers, and help turn early concepts into tested, manufacturable flight hardware.
About ACTAdvanced Cooling Technologies, Inc. (ACT) is a leading provider of thermal management solutions for aerospace, defense, data centers, energy, and industrial applications. For more than 20 years, ACT has engineered and manufactured innovative technologies that solve complex thermal challenges in demanding environments. Our team is driven by continuous innovation, teamwork, and collaboration, delivering reliable solutions that support critical missions and next-generation technologies worldwide.
ACT's capabilities extend from advanced engineering and analysis through prototyping, testing, qualification, and manufacturing. For our Space Systems engineers, that creates an opportunity to stay connected to a program throughout its development rather than working on one isolated piece of a much larger project.
As the commercial space industry continues to grow and new missions become increasingly ambitious, ACT is growing with it.
Position SummaryThe Space Systems Senior Engineer supports the development of spacecraft hardware and systems across multiple phases of the engineering lifecycle, ranging from concept generation and initial design through detailed analysis, prototype hardware fabrication, testing, and volume production.
Projects can range from modifications of proven designs to true "blank sheet of paper" development programs requiring new ideas, new approaches, and advanced performance testing.
At any given time, the Senior Engineer may be responsible for the success of multiple projects, providing the opportunity to work across many aspects of the product development cycle. You'll work as part of a multidisciplinary team of engineers and technicians to develop complex systems and solve challenging technical problems.
Candidates with a strong technical background and experience designing complex, manufacturable components and systems will excel in this position.
What You'll Work OnThis is not an engineering role where you'll spend years focused on one small subsystem.
As a Space Systems Senior Engineer, you'll have opportunities to work across a diverse range of spacecraft programs and technical challenges.
Depending on the project, you may be developing a new spacecraft thermal or mechanical concept, evaluating design trades, performing detailed analysis, developing CAD models, reviewing manufacturing drawings, working alongside technicians building prototype hardware, evaluating test results, or meeting directly with a customer to solve a mission-specific challenge.
Your work may support:
- Satellites and spacecraft
- Scientific instruments and payloads
- Commercial space platforms
- Spacecraft thermal control systems
- Structural and mechanical systems
- Radiators and heat rejection systems
- Prototype and flight hardware
- Emerging spacecraft architectures and technologies
- Programs ranging from one-of-a-kind missions to higher-volume spacecraft production
Some projects build on decades of proven engineering. Others start with a set of requirements, an empty whiteboard, and a problem no one has solved yet.
Work Across the Full Engineering Lifecycle
Concept ? Analysis? Design ? Build? Test? Qualify? Production? Flight
At ACT, engineering doesn't stop when the model is complete. Our engineers work closely with manufacturing and technicians throughout development, creating an environment where you can see your ideas become hardware, learn from testing, refine the design, and help successfully transition products into production.
That combination of analysis, hands-on development, and manufacturing is a major part of what makes engineering at ACT different.
Responsibilities Include:- All aspects of initial product design including:
- Innovative concept generation
- Excel or hand calculation analytical analysis
- Detailed Thermal Analyses (steady state, transients)
- Ability to perform basic structural assessments a plus
- Manufacturing Drawing generation and review
- Compliance Matrix generation and review
- 3-D CAD modeling (Solidworks)
- Fabrication procedures & travelers
- Working with a diverse group of engineers and technicians
- Managing program schedules and…
