About this contract

OUTSIDE IR35

We are seeking an experienced Senior Electrical Systems Engineer to join a high-profile, long term space programme based in London. The successful candidate will support the technical development of advanced spacecraft systems, with a particular focus on electrical and avionics architecture, interfaces, requirements and system-level integration.

This is an initial 6-month contract, with the role sitting within a 5-year programme, offering the opportunity to contribute to a technically challenging project across its development and integration lifecycle. The role is offered on a hybrid basis, requiring 2 days per week on-site in London, with the remainder worked remotely.

Key Responsibilities

Electrical Systems Engineering

• Develop and maintain spacecraft electrical system and avionics architectures.

• Provide electrical systems engineering from initial specification through design, integration and test.

• Perform requirements engineering, including requirements analysis, allocation and flow-down/flow-up.

• Define and manage electrical interfaces between spacecraft subsystems and equipment.

• Support On-Board Data Handling, Electrical Power Systems, Satellite Communications, remote sensing and robotics teams.

• Support the definition and development of electrical and electronic test equipment. • Define and support verification, validation and test plans.

• Contribute to system-level development, verification and AIV/T activities. • Support spacecraft and electrical unit integration and testing.

• Investigate technical issues and support fault diagnosis and resolution.

• Produce technical documentation, engineering reports and verification evidence.

• Support system and spacecraft-level technical reviews.

• Contribute to operational documentation and procedures, including preparation for commissioning and in-orbit operations.

Requirements & Technical Documentation

• Develop, review and maintain system-level electrical requirements.

• Define and document electrical interfaces between units and subsystems.

• Contribute to technical specifications, design documentation, verification plans and engineering reports.

• Support FMEA and other system-level analysis activities.

• Ensure electrical engineering activities are appropriately documented throughout the project lifecycle. Procurement & Supplier Management

• Support the preparation of Requests for Proposal (RFPs) for electrical and electronic hardware.

• Review supplier technical proposals and provide technical input to supplier selection.

• Provide technical supervision and support for subcontractors and external suppliers.

• Review and assess electrical aspects of spacecraft equipment developed by other disciplines.

• Support the delivery and acceptance of electrical system hardware.

Design & Development

• Contribute to the development of future electrical and avionics system architectures.

• Support detailed electronics design and development activities where required.

• Review electrical and electronic designs for compliance with system requirements.

• Support hardware development, build, integration and test.

• Contribute to design improvement and technical problem-solving throughout the programme.

Essential Experience & Qualifications

• BSc or MSc in Electrical Engineering, Electronic Engineering, Aerospace Engineering, Physics or a related discipline.

• 5+ years of relevant Electrical Engineering experience within the space industry, ideally in systems, avionics, data handling or power electronics.

• Strong experience in system-level requirements engineering and electrical interfaces. • Experience producing and reviewing technical engineering documentation.

• Experience working through established engineering and programme lifecycles.

• Previous active participation in formal design reviews, such as PDR and CDR.

• Experience supporting system integration, verification and testing.

• Strong understanding of electrical and electronic systems.

• Ability to work collaboratively across electrical, avionics, software, mechanical and systems engineering disciplines.

• Strong organisational skills, with the ability to manage multiple technical activities simultaneously.

Desirable Experience

• Detailed understanding of electronics analysis, design, build and test.

• Hands-on electronics design and test experience.

• Experience with fault diagnosis and technical troubleshooting.

• Knowledge of ECSS, MIL standards and standards tailoring.

• Experience with EMC/EMI constraints, analysis and mitigation.

• Experience with FMEA and system-level verification and validation.

• Experience with spacecraft AIV/AIT activities. • Experience supporting flight operations or in-orbit commissioning.

• Experience providing technical leadership within an engineering team.

• Experience working with institutional customers such as ESA or the UK Space Agency.

• Experience managing or technically supervising suppliers and subcontractors
