## Description

We are seeking a motivated and technically strong Systems Engineer with experience in space missions - ideally small satellites (Microsats, Nanosats, CubeSats).

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.

Support to the spacecraft operations team for spacecraft anomaly identification and resolution may also be required.

You'll work closely with multidisciplinary engineering teams and play a key role in ensuring technical coherence, system performance, and successful delivery of mission objectives.

You will be comfortable working as part of a team to deliver projects to a variety of customers including institutional, academic and commercial organisations.

Whilst the primary responsibilities of the role lie in project delivery, you may get involved in other areas of the business including space technology and/or space mission studies or R&D projects and technical support to bids.

Core Duties

Support or lead design activities for small satellite missions;

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 to Spacecraft commissioning activities;

Spacecraft anomaly investigation and resolution;

Mission concept development in support of studies, R&D activities and bids;

Support engagement with external equipment providers;

Produce inputs for internal and customer reviews and present progress to internal stakeholder and external customers.
