Systems Engineering & Assurance Manager

We design and deliver intelligent integrated technology solutions that transform the way people work, live, and stay safe. In our Public Services sector, we are trusted to protect what matters most. From Higher Risk Buildings (HRBs) to Critical National Infrastructure (CNI) and transportation, our systems ensure operational resilience and public safety.

We are seeking a Systems Engineering & Assurance Manager to lead and assure the technical delivery of complex safety, security and networking integrations. This is a pivotal role where technical rigor meets public safety. You will act as the technical authority for highly regulated and complex projects, ensuring that our integrated solutions — ranging from CCTV and Access Control to complex situational awareness platforms — are safe, secure, compliant, and fully verified against client and regulatory requirements.

You will champion the Systems Engineering lifecycle (V-Model) across our Public Services sector, ensuring relevant contract and regulatory requirements are fulfilled throughout the project lifecycle. You will work across multiple sectors and systems applications within infrastructure and the built environment.

Key Responsibilities

• Lead the capture, analysis, and management of stakeholder and regulatory requirements.
• Own the Requirements Traceability Matrix (RTM) to ensure every design decision can be traced back to a specific client need or safety regulation.
• Develop robust high‑level and low‑level system designs for integrated security systems, ensuring seamless interoperability between hardware, software, and network layers.
• Manage the technical interfaces between diverse engineering disciplines (e.g., Safety & Security, Networking, Civils, and M&E), identifying and resolving clashes early in the design phase.
• Implement strict configuration control and change management processes.
• Ensure no change is implemented without a full impact assessment on safety and security performance.

Verification, Validation & Assurance

• Oversee the technical integration of sub‑systems (software, hardware, civils infrastructure, networks and existing systems), ensuring they function as a cohesive whole, particularly in complex, safety‑critical environments.
• Lead design review, verification and audit activities, and prepare the Design Compliance Report to demonstrate compliance with all relevant standards and regulations.
• Define and lead the V&V strategy.
• Prepare test plans and reports for Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT) and System Integration Tests (SIT) to ensure systems perform exactly as intended.
• Champion safety‑critical engineering processes.
• Ensure systems meet specific functional safety requirements as required by industry‑specific standards and adhere to quality assurance frameworks (ISO 9001).
• Bridge the gap between physical security and cyber security.
• Harden all systems against cyber threats and meet relevant assurance standards (e.g., Cyber Essentials Plus, ISO 27001 constraints).

Regulatory and Standards Compliance

• Act as the Subject Matter Expert (SME) for industry‑specific regulations, ensuring project delivery aligns with the most current national and international standards.
• Ensure compliance with the Building Safety Act 2022 and contribute to the "Golden Thread" of information for the client in Higher Risk Buildings.
• Adhere to Transport for London and Network Rail standards where applicable in Rail projects.
• Meet Department for Transport (DfT) security requirements and Civil Aviation Authority (CAA) guidelines in Airports and Airside projects.

Qualifications

• Experience in Systems Engineering within a highly regulated environment (Higher‑Risk Buildings, Aviation, Rail, Defence, CNI or adjacent sectors).
• Good working knowledge of the Systems Engineering "V‑Model".
• Proficiency in creating requirements management, V&V tools (e.g., requirements specifications, RTMs, plan templates).
• Understanding of Safety & Security systems (CCTV, PIDS, ACS) and their integration onto IP networks.
• Incorporated (IEng), Chartered Engineer (CEng) or Chartered Quality Professional (CQP) status or equivalent professional recognition or working towards.
• Understanding of UK safety and security standards, including NSI frameworks.
• Experience with OT and IoT systems, including integration, lifecycle management, and cyber security principles.
• Background in safety‑critical systems and compliance with UK regulatory bodies.
