Description

Due to the growth of our propulsion centre of excellence based at our Harwell site in the UK, we are looking for an experienced chemical propulsion engineer. Drawing on your significant space propulsion systems experience (minimum 5 years) in chemical propulsion this is an excellent time to be joining this team. The position will be based at the TAS UK Harwell office.

Primary Purpose of the Role:

Reporting to the Propulsion Systems Engineering Manager the Systems Engineer will perform, but it not limited to the following type of activities:

To be a senior figure supporting various projects and team members in general within the existing team.
Propulsion subsystem and propulsion equipment activities (EP and/or CP) during Phase A/B/C/D/E for recurring TAS satellite product line application programmes or developments.
Be the primary technical point of contact responsible and lead for the propulsion subsystem, in both MAIT and Architecture, including procured propulsion equipment’s on a project, interfacing with the, customer technical teams, PMO, AIT team, procurement and other subsystem experts, (such as Mech/Thermal, AOCS)

Interpret mission/customer specific and generic system level requirements and establishing the baseline technical requirements document (TRD) for the propulsion subsystem

Provide technical support to system level propulsion trade-offs for optimization of the satellite and mission design.

Support the preparation of subsystem design justification documentation for major design reviews throughout the project life cycle

Present subsystem design justification in major design reviews throughout the project life cycle in cooperation with the Program Management Office and other subsystems

Review and consolidate the technical documentation for the system through the different project life cycle milestones & reviews (EQSR, PDR, CDR, MRR, TRR, QR, etc)

Establishing integration and test plans and requirements for the subsystem Development and improvement of new analysis tools in specialised fluidic software (e.g. EcosimPro), and also in Excel, MATLAB, and Python.

Performance analyses in support of non-conformance review board.

Prepare/update subsystem analysis reports through the different project life cycle milestones & reviews (PDR, CDR, QR etc)
