Mission Simulation Engineer III

Mission Simulation Engineer III – Tera Wave Integrated System Modelling Team

As a member of the Tera Wave integrated system modelling team, you will play a foundational role in the development of an integrated mission simulation model that captures the full‑system behaviour of the Tera Wave satellite constellation. The integrated mission simulation model you help build will serve as a critical program‑wide tool used to analyse, optimise and validate constellation performance from early design through deployment and operations.

• Take a lead role in implementing, maintaining and continuously improving the Tera Wave integrated mission simulation model within the integrated systems modelling team.
• Develop and maintain high‑fidelity orbital mechanics models including orbit propagation, constellation geometry, station‑keeping manoeuvres and coverage analysis.
• Develop and apply orbit optimisation methodologies to maximise coverage, capacity and payload utilisation while minimising constellation system cost and operational complexity.
• Build and integrate beam assignment and payload scheduling models that reflect realistic antenna patterns, coverage footprints and link performance constraints across both RF and optical link domains.
• Develop simulation capabilities for both inter‑satellite links (ISL) and ground‑to‑space links, spanning RF and optical link types, including link budget and availability modelling.
• Develop traffic routing and load utilisation models that simulate end‑to‑end data flow across the constellation under realistic and stressing demand scenarios.
• Develop and maintain spacecraft power models capturing solar array generation, battery cycling and power consumption across all operational modes.
• Model constellation deployment phases and build‑up timelines to support programme planning, architecture trades and early operations analysis.
• Collaborate with fleet management, mission operations, payload, power, network and GNC engineering teams to ensure simulation inputs and fidelity levels are consistent with subsystem designs and interface definitions.
• Engage with the GNC team to ensure orbital mechanics modelling assumptions, attitude control constraints and manoeuvre planning are accurately reflected within the integrated simulation framework.
• Partner with systems engineering teams to define and validate constellation‑level performance requirements through simulation‑based analysis.
• Define and support simulation verification and validation approaches, including benchmarking against analytical models, heritage data and in‑orbit telemetry as it becomes available.
• Develop workflows and tooling to support parametric trade studies and sensitivity analyses that directly inform constellation architecture and design decisions.
• Partner with business and product teams to translate simulation outputs—including coverage availability, capacity margins and service continuity metrics—into inputs that drive revenue modelling and define viable commercial service tiers and offerings.
• Communicate simulation methodology, assumptions and results clearly to both technical and non‑technical stakeholders through written reports, presentations and data visualisations.
• Maintain simulation software infrastructure including version control, documentation and regression testing frameworks.
• Lead root‑cause investigations when simulation predictions deviate from test or in‑orbit data and drive model updates accordingly.
• Contribute to team growth through supporting hiring efforts, identifying capability gaps and mentoring junior simulation and systems engineers.

• Relocation provided.
• Travel expected up to 15% of the time.

• Minimum of a master’s degree in aerospace engineering, systems engineering, applied mathematics or equivalent technical field.
• 5+ years of related experience (including graduate work) in spacecraft systems engineering, mission analysis or constellation simulation, with demonstrated hands‑on expertise in astrodynamics and orbital mechanics.
• Proficiency in simulation development and scripting tools such as Python, MATLAB or C++, with experience building and maintaining…
