Aim high, go beyond! At Open Cosmos we are solving the world’s biggest challenges from space, providing businesses, governments and researchers access to more readily available information than ever before - ready for the challenge? Then read on…
Working in the Satcoms Software Team
Our team designs, builds, and operates the software infrastructure behind Open Cosmos’ satellite communications services. From network planning and mission simulation to real-time telemetry processing and digital twin modelling, we provide the foundation for scalable, intelligent, and secure connectivity from space to ground. We use modern technologies, agile methods, and tight collaboration with hardware, mission, and commercial teams to deliver value quickly.
What will you be doing?
As a Simulation & Optimisation Engineer, you will develop high-fidelity simulation frameworks and optimisation algorithms that shape the performance and intelligence of Open Cosmos’ Satcom infrastructure. Your models will represent the full system lifecycle—from constellation dynamics to ground interactions—and will be integrated into decision-making workflows across engineering and operations.
You’ll build tools for trade-off analysis, sensitivity studies, and autonomous performance management, supporting decisions on architecture, resource allocation, traffic routing, and network optimisation. Your work will also contribute to digital twins, performance prediction engines, and early mission and system design assessments. Collaboration with payload, network, and system performance teams will be key to ensuring your models deliver practical, impactful outcomes.
What you need to be successful
We care about what you can do and how you think. If this role excites you, we want to hear from you, even if you are not sure you tick every box.
Different seniority levels will be assessed for this role.
To succeed in this role, you will need:
- A strong background in designing and implementing simulation frameworks or optimisation systems—ideally within the satellite or telecom domain.
- Proficiency in software development, particularly with Python, C++, MATLAB/Simulink, or similar tools used for modelling, simulation, and algorithm development.
- A solid grasp of modern software architectures, including microservices, scalable compute pipelines, and cloud-native frameworks.
- Hands-on work with large-scale discrete event or Monte Carlo simulations for complex technical systems.
- In-depth understanding of RF link analysis, orbital dynamics, routing algorithms, and network behaviour.
- Expertise in mathematical optimisation, including linear/non-linear programming, constraint solvers, combinatorial methods, and metaheuristics.
- The ability to translate engineering and business challenges into quantitative models with real-world impact.
