Experience designing & analyzing thermal systems (heat exchangers, radiators, cold plates), or fluid components (valves, regulators, pumps, lines, manifolds).
Strong understanding of fluid mechanics, heat transfer, and thermodynamics.
Strong understanding of space environments (grounding/bonding, thermal, vacuum, regolith) and how they affect design decisions.
Experience in defining and implementing engineering standards, processes, and practices.
Proficiency with mechanical design tools (NX, Creo, or Solidworks) and test analysis tools (Python, or equivalent).
Track record of delivering outcomes in ambiguous, fast-moving environments.
Uses good judgement to solve problems proactively, positively impacting hard challenges.
Proven to deliver high quality results under tight deadlines.
Bachelors Degree in Mechanical Engineering, Aerospace Engineering, or related field required.

Nice To Haves

Familiarity with flight hardware development and certification is preferred.
Knowledge of NASA or commercial space program standards is preferred.
Experience with CFD, FEA, or thermal modeling tools such as ANSYS Fluent, Star-CCM+, Thermal Desktop, SINDA/Fluint is preferred.

Responsibilities

Define and create modern space station thermal-fluid system standards and practices.
Own design, development, integration, and verification of thermal-fluid hardware for crewed spaceflight applications.
Lead design and production reviews internally and externally with suppliers and customers.
Collaborate with cross-functional teams (Stress, avionics, manufacturing) to ensure proper integration and meet mission requirements.
Lead thermal system trade studies and architecture decisions balancing performance, reliability, manufacturability, operability, schedule, and cost.
Perform thermal-fluid system sizing and analysis for thermal-fluid hardware (radiators, pumps, heat exchangers, cold plates, accumulators, valves, regulators, lines, manifolds, and thermal interfaces).
Establish an efficient product lifecycle starting in the supply chain all the way through final integration that balances cost, complexity, and quality.
Generate and/or review CAD models, engineering schematics, drawings, analysis, assessments, and procedures for components, assemblies, and integrated assembly.
Develop and review thermal mathematical models and simulations to predict steady-state and transient thermal performance across all mission phases.
Conduct thermal-fluid analyses including pressure drop calculations, flow balancing, heat transfer assessments, fluid network modeling, and system performance characterization.
Validate designs by analysis or test, building development articles as needed.
Support the manufacturing and assembly of hardware in the facility and through on-orbit operation.
Communicate project progress, status, and potential issues to stakeholders and leadership.
Implement and maintain agile project management methodologies throughout the project lifecycle.
Perform additional job duties as assigned.
