Job summary

Actalent is seeking a Mechanical Engineer to own end-to-end mechanical designs for advanced quantum infrastructure projects. You will lead from concept to print-ready drawings, perform thermal and structural analyses, and validate designs using FEA/CFD tools in a fast-paced deep-tech environment.

The role emphasizes heat transfer, thermodynamics, and cryogenic system challenges, with remote work flexibility and opportunities to contribute to cutting-edge instrumentation and vacuum systems.

Qualifications

• . Advanced mechanical design experience with ownership of complex systems.
• . Proven experience from concept through drawing release and print-ready status.
• . Strong proficiency in heat transfer analysis and thermodynamics.
• . Deep understanding of heat transfer mechanisms for engineering problems.
• . Experience with structural analysis for components and assemblies.
• . Ability to make decisions based on FEA/CFD results.
• . Hands-on experience with major CAD/CAE tools.
• . Produce high-quality engineering drawings for manufacturing.
• . 7+ years experience; not suitable for new graduates.
• . Availability during core hours 8:00 AM to 3:00 PM MST.

Responsibilities

• - Own mechanical designs from concept through print-ready drawing release, ensuring performance and manufacturability.
• - Advance designs to detailed, print-ready state with models, assemblies and drawings.
• - Perform heat transfer analysis, thermodynamic assessments, thermal modeling.
• - Analyze heat transfer mechanisms in cryogenic and thermal engineering challenges.
• - Conduct structural evaluation to verify strength, stiffness, and safety.
• - Use FEA and CFD tools to validate thermal and structural performance.
• - Make engineering decisions based on analysis results and communicate rationale.
• - Develop 3D CAD models and assemblies with high-quality, parametric design.
• - Create detailed drawings with tolerances and notes for fabrication.
• - Collaborate with cross-functional teams in a deep-tech setting.
• - Support dilution refrigerators and cryogenic systems used in quantum computing.
• - Contribute to vacuum systems, advanced manufacturing equipment and instrumentation.
