Full-Time | On-Site
Package:
Competitive Salary + Equity + Benefits + Flexible PTO
Are you a thermal engineering specialist passionate about defining architectures and analysis methodologies for next-generation satellite platforms?
On offer is the opportunity to join a high-growth space company at the forefront of digital spacecraft engineering. You'll take ownership of advanced thermal modelling, simulation workflows, and environmental verification strategies that drive mission-critical design decisions.
Join a team shaping the thermal architecture of fast-moving aerospace programs. You'll work across systems, mechanical, and analysis functions to optimize mass, power, and thermal margin, ensuring spacecraft survive and perform in the harshest orbital environments.
This position would suit a deeply technical thermal engineer who thrives on high-fidelity simulation, physics-driven optimisation, and bridging the gap between analytical models and validated flight hardware.
Key Responsibilities
• Build and manage high-fidelity thermal models for spacecraft buses and payloads, including transient, orbital, and articulated geometry cases.
• Develop advanced analysis methodologies and automated workflows to accelerate design iteration and trade studies.
• Architect spacecraft thermal control systems (TCS), selecting hardware such as heat pipes, radiators, MLI, heaters, and coatings.
• Lead planning and execution of Thermal Vacuum (TVAC) tests and correlate test data with analytical predictions.
• Guide the thermal engineering team through model reviews, best practices, and solver configuration.
• Collaborate with cross-disciplinary teams to ensure thermal performance informs system-level decisions.
Essential Skills and Experience
• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field.
• 5+ years' experience in satellite thermal analysis and thermal control system design.
• Deep proficiency in Simcenter 3D Space Systems Thermal (formerly TMG), including large FEM assemblies and advanced orbital/operational scenarios.
• Strong understanding of thermal hardware such as CCHP/LHP heat pipes, PCM, coatings, and passive/active TCS elements.
• Proven experience correlating models to TVAC or on-orbit telemetry.
• Strong analytical, simulation, and problem-solving skills with attention to detail.
