Systems Engineer - Requirements

We're looking for an experienced Technical Requirements Systems Engineer to drive the definition, structure, and governance of system and software requirements for a complex, high‑impact engineering programme.

This is a critical role at the heart of delivery — translating stakeholder needs into clear, testable, and traceable requirements that underpin system design, integration, and validation.

🔍 About the Role

You'll take ownership of the requirements lifecycle — from early stakeholder engagement through to detailed specification — ensuring alignment across engineering, development, and test teams.

You'll lead the development of both high‑level and detailed specifications, with a strong focus on traceability, governance, and real-world testability.

🧩 Key Responsibilities

🔹 Requirements Analysis & Governance

• Analyse and refine system requirements to align with programme objectives
• Translate stakeholder needs into clear, structured, and testable requirements
• Develop and maintain a robust requirements governance framework
• Traceability (end-to-end)
• Version control
• Change management

🔹 Stakeholder Engagement

• Collaborate with a wide range of stakeholders, including:
• End users of test systems
• System designers and engineers
• Software developers
• Integration & test teams
• • Facilitate workshops, reviews, and requirement validation sessions
• Ensure alignment between technical delivery and business needs

🔹 Documentation & Specification

• Own the creation and progression of:
• Technical Requirements Specification (TRS)
• Software Requirements Specification (SRS)
• • Produce high-quality documentation that is:
• Clear, complete, and unambiguous
• Structured and maintainable
• Fit for engineering and test teams

🔹 System & Software Requirements Development

• Define end-to-end system requirements including:
• Hardware
• Software
• Interfaces
• Constraints
• • Break down high-level requirements into:
• Detailed software functionality
• Performance and behavioural requirements
• • Ensure full traceability between TRS and SRS

🔹 Integration, Test & Simulation

• Ensure requirements are testable and measurable
• Align requirements with system integration and validation strategies
• Support the use of simulation-led testing to validate system behaviour

📦 Key Deliverables

✅ Technical Requirements Specification (TRS)

A complete, high-level requirements document covering the full test system, including:

• Stakeholder-driven inputs
• Hardware, software, and interface requirements
• System constraints and dependencies

✅ Software Requirements Specification (SRS)

A detailed, structured breakdown of software requirements that:

• Defines system functionality and behaviour
• Links directly back to TRS (full traceability)
• Supports development, integration, and testing

🛠️ What We're Looking For

• Strong experience in requirements engineering within complex systems environments
• Proven track record delivering TRS / SRS documentation
• Deep understanding of:
• System integration & testing
• Verification & validation processes
• Simulation-based testing approaches
• • Experience with requirements management tools (e.g. DOORS, Jama, Polarion)
• Excellent stakeholder engagement and communication skills
• Highly structured, detail-oriented, and analytical mindset

🎯 Why Join?

• Work at the centre of a technically complex, high-impact programme
• Shape how requirements drive design, development, and testing
• Collaborate with multidisciplinary teams across engineering, software, and operations
• Play a key role in ensuring successful system delivery
