# Systems Engineer- Requirements

> Positiv+ Cohort · Stevenage, United Kingdom (Hybrid) · — · Posted 2026-06-23

**Workplace:** hybrid

## Description

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.

If you thrive on bringing structure to complexity and enjoy working across systems, software, and testing domains, we’d love to hear from you.

### **🔍 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
