Systems Engineer

Salary: £40,000 - 40,000 per year

Requirements

• We are seeking an experienced Systems Engineer with proven expertise in applying Systems Engineering principles and systems development approaches.
• We require a degree in Engineering such as Systems, Mechanical, Optical, Electronics, or Software, or a closely related discipline such as Physics.
• You should have a collaborative, proactive approach and confidence working in the presence of technical ambiguity.
• You must have experience applying Systems Engineering principles to the design and development of complex or multidisciplinary systems.
• You should have experience with early lifecycle systems engineering activities, including requirements definition, system architecture, modelling, or functional decomposition.
• You must have experience working on complex technical systems such as instrumentation, research facilities, or bespoke engineered systems.
• You should be familiar with systems development approaches such as V-model, iterative, or agile.
• You must be able to produce clear and structured technical artefacts such as requirements, architectures, and models.
• Desirable: knowledge of time and frequency measurement, time scales, or precision metrology.
• Desirable: experience with real-time monitoring and control of electronic or optical hardware.
• Desirable: experience with satellite communications, optical fibre networks, or GNSS-based systems.
• Desirable: experience in research or laboratory-based engineering environments.
• We require the ability to obtain BPSS security clearance.
• For this role, we require SC clearance with no restrictions, or the ability to obtain SC clearance.

Responsibilities

• We will ask you to support early lifecycle systems engineering activities, including concept definition, functional decomposition, and requirements development.
• You will define system and subsystem architectures, including boundaries, interfaces, and packaging, in collaboration with multidisciplinary teams.
• You will model and analyse system behaviour, interfaces, and performance to inform design decisions and reduce technical risk.
• You will identify, assess, and communicate technical risks, assumptions, and trade-offs clearly and proportionately.
• You will produce clear, structured systems engineering artefacts, including requirements, architectures, and models, in line with our internal processes, to time, cost, and quality.
• You will ensure traceability from user needs through to system requirements and design decisions across the product lifecycle.
