Mission Simulation Engineer III

Mission Simulation Engineer III – TeraWave Integrated System Modelling Team As a member of the TeraWave 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 TeraWave 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. Responsibilities Take a lead role in implementing, maintaining and continuously improving the TeraWave 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. Special Mentions Relocation provided. Travel expected up to 15% of the time. Minimum Qualifications 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 complex multi‑physics or multi‑domain models. Experience developing or integrating simulation models spanning at least two of the following domains: orbital mechanics, RF or optical link performance, spacecraft power systems or network traffic modelling. Familiarity with satellite link budget analysis, beam coverage modelling and payload performance metrics across RF and optical communications links. Working knowledge of spacecraft power system fundamentals including solar array performance, battery modelling and power mode management. Ability to read and interpret interface control documents, systems requirements documents and engineering specifications across multiple disciplines. Ability to perform data analysis and reduction and present technical information in a clear and compelling visual format. Preferred Qualifications Successful candidates in this role typically have 10+ years in spacecraft mission analysis, constellation systems engineering or integrated simulation development for non‑spacecraft systems of similar complexity. Experience with orbit optimisation methods and their application to large‑scale constellation design, including coverage optimisation, phasing strategies and cost‑driven architecture trades. Working knowledge of satellite network routing architectures including inter‑satellite links (ISL), ground station connectivity and traffic management protocols. Familiarity with optimisation techniques or scheduling algorithms applied to satellite resource management, beam assignment or constellation operations. Experience modelling constellation deployment sequences, launch campaign planning and incremental capability build‑up. Background in LEO or MEO large‑scale constellation design, deployment sequencing or on‑orbit operations. Leadership or management experience as well as a history of mentoring junior engineers. Ph.D. in aerospace engineering, applied mathematics or a closely related field with a thesis topic relevant to astrodynamics, mission analysis or satellite systems simulation.
