Job Description:
In this role, you will contribute to the full lifecycle of space system development: from concept design and requirements definition, through integration, verification, and mission operations.

Core Duties:
- Support or lead design and operational activities for small satellite missions
- Support to Spacecraft commissioning activities and Spacecraft anomaly investigation and resolution
- Perform mission needs analysis, trade studies, and system architecture development
- Define, manage, and validate system-level requirements and interfaces
- Conduct functional analyses, budgets (mass, power, data, thermal), and performance modelling
- Support engagement with external equipment providers
- Produce inputs for internal and customer reviews and present progress to internal stakeholders and external customers
