Propulsion Design Engineer - Thermal
New Today
Astro Mechanica is a vertically integrated aerospace company building a faster, more connected future. Our mission is to democratize high-speed flight by making supersonic travel flexible, accessible, and sustainable. We believe that rapid, on-demand, point-to-point global mobility will become the new standard for moving people and goods across the planet. To achieve this, we are integrating our advanced airframe and engine technologies-which include Duality™, our proprietary dual-use propulsion system-with a new flight operations model to make supersonic transport as efficient and economical as commercial air travel is today. In the near term, we are developing adaptable, high-speed systems to close aircraft performance gaps for the United States government.
WHO WE ARE:
We're a team of hardcore engineers who live and breathe aerospace. We're generalists who each have subject matter expertise and operate in a flat organizational structure. We move fast and build world-changing technology in a pragmatic and competent workplace culture.
WHO YOU ARE:
Astro Mechanica is looking for a Propulsion Design Engineer to join our growing team. The ideal candidate is very capable generalist designer but also someone who can take full ownership of thermal system design from concept to production and has a deep understanding of their impact on surrounding systems. Technical challenges are resolved from first principles. Your work at Astro Mechanica will have a direct impact on the thermal management and overall performance of the Duality™ engine.
In this role, your mission will be to architect, build, and validate thermal systems from early prototype through flight qualification, vehicle integration, and aircraft flight. You embody the test-like-you-fly philosophy.
WHAT YOU'LL DO:
- Generate CAD models, detailed engineering drawings, and apply appropriate GD&T
- Architect thermal systems and develop 1-D fluid network models to predict system behavior, transient responses, and sensitivities
- Architect and complete detailed thermal system design and size fluid system components such as pumps, heat exchangers, valves, and regulators
- Use hand calculations and computational tools (CFD) to optimize component and system effectiveness
- Analyze heat loads, conduction paths, and interface temperatures, and define instrumentation to anchor models with test data
- Own and present design reviews to the team
- Assemble prototypes, establish test procedures, and analyze data to verify requirements and performance metrics
- Diagnose thermal system problems efficiently and determine corrective actions
WHAT WE'RE LOOKING FOR:
- 2+ years hands-on experience with thermal and fluid systems in propulsion or similarly complex environments
- Proficient in CAD modeling (Siemens NX), drawing generation, and GD&T
- Strong understanding of thermodynamics, heat transfer, and fluid behavior in complex systems
- Experience designing and analyzing thermal systems using CFD and 1D network modeling tools
- Informed on instrumentation types and limitations, with ability to model-anchor with test data
- Takes initiative for continuous improvement (not just completing assigned tasks)
- Flexibility to work in fast-paced environment
- Attentive to detail and maintain a high level of quality in all work
PERKS & BENEFITS:
- Comprehensive medical, dental, and vision insurance, including Flexible Spending Accounts (FSA)
- 401(k) program and transparent stock option plan
- Self-managed and flexible time-off policy, including PTO, paid holidays, and sick time
- Flexible work environment
- Company-funded perks, including weekly team lunches and Astro Mechanica swag
ADDITIONAL INFORMATION:
At Astro Mechanica, we highly value in-office work to foster collaboration and strengthen our company culture. We consider working in the office five days a week an essential part of the employee's role.
Astro Mechanica is an equal opportunity employer. We proudly recruit and hire a diverse workforce and are committed to creating an inclusive environment for all employees.
