1. Senior Data Architect (Grade 7)

Department: Energy Security & Net Zero (DESNZ)
Salary: £55,105 – £67,565 (plus DDaT allowance up to £22,885 in specific locations)

The Role: Architect of the Green Transition
As a Senior Data Architect at DESNZ, you are not merely a technician; you are a “change agent.” In 2026, the UK’s Net Zero mission relies entirely on the accuracy of energy consumption and production data. You will design the Enterprise Data Model that allows ministers to make evidence-based decisions on grid decarbonization and renewable investments.

Key Responsibilities:

Data Flow Mapping: Visualizing how data moves from offshore wind farms and smart meters into departmental databases.
Standards Setting: Establishing metadata standards to ensure data is discoverable and “interoperable” across the wider government network.
Cloud Architecture: Designing scalable solutions within SQL, NoSQL, and modern Data Lakes to handle the massive influx of environmental sensor data.

Top Candidate Requirement: You must possess deep expertise in conceptual, logical, and physical data modelling. Experience in migrating legacy systems to modern cloud environments is essential for this G7 leadership post.

2. Technology Adoption Manager (HEO)

Department: Crown Prosecution Service (CPS)
Salary: £35,935 – £39,885

The Role: The Bridge to Digital Justice
The Crown Prosecution Service is undergoing a massive digital overhaul in 2026. The Technology Adoption Manager serves as the vital link between technical IT developers and the frontline legal staff (prosecutors and lawyers). Your mission is to ensure that digital tools—such as AI-assisted evidence review systems—are embraced, not ignored.

Key Responsibilities:

Training Design: Creating intuitive digital learning resources and “how-to” guides for non-technical legal staff.
Product Rollout: Managing the internal communication strategy for new software deployments.
Feedback Loops: Gathering user insights to inform the IT department on how to make tools more “user-centric” for the courtroom environment.

Top Candidate Requirement: A proven track record in stakeholder engagement. You must be able to translate “tech-speak” into plain English and demonstrate experience in delivering large-scale technology training programs.

3. National Security Lead, Strategic Awareness (Grade 7)

Department: Science, Innovation & Technology (DSIT)
Location: London (AI Security Institute – AISI)
Salary: £58,040

The Role: Defending the Frontier of AI
Based within the world-renowned AI Security Institute (AISI), this role focuses on “Transformative AI”—models so powerful they could redefine global security. You will be at the “tip of the spear” in identifying and mitigating existential risks posed by emerging AI technologies.

Key Responsibilities:

Risk Tracking: Monitoring “warning signals” that AI models are becoming capable of assisting in bio-weapon development or autonomous cyber-attacks.
Ministerial Briefing: Distilling highly technical AI threat intelligence into clear, actionable briefings for senior Cabinet ministers.
Policy Influence: Helping to shape the international “AI Safety Benchmarks” used by the UK and its allies.

Top Candidate Requirement: Subject Matter Expertise (SME) in AI security. You should have a background in high-profile government projects and a deep understanding of the adversarial capabilities of Large Language Models (LLMs).

4. Deployable and Reactive Team (DaRT) Officer

Department: House of Commons
Salary: £30,316 – £33,896

The Role: The Vanguard of Parliament
The DaRT Officer is a high-intensity, uniformed security role within the Parliamentary Estate. Unlike static security, DaRT is a “mobile asset” designed to respond to fluid threats in a high-profile environment. This is a role for those who thrive under pressure and possess “Elite Awareness.”

Key Responsibilities:

Rapid Response: Being the first on the scene for security breaches or immediate threats to the Palace of Westminster.
Behavioral Detection: Conducting covert observations to identify suspicious patterns of behavior among the thousands of daily visitors.
Close Protection: Providing immediate security support for dignitaries, MPs, and visiting heads of state.

Top Candidate Requirement: A specialist background in security operations (surveillance, close protection, or military police). The ability to maintain absolute composure during unpredictable incidents is the defining trait of a DaRT Officer.

5. Private Secretary to the CEO

Department: UK Debt Management Office (DMO)
Salary: £60,000 – £75,000

The Role: The Gatekeeper of National Finance
Operating at the heart of the City of London, the Private Secretary is the “right hand” to the CEO of the DMO. You will be managing the office that handles the UK’s massive debt issuance and cash management operations. This is a high-status role requiring a blend of financial acumen and diplomatic finesse.

Key Responsibilities:

Information Distillation: Managing a vast flow of complex financial data from the Treasury and the Bank of England, summarizing it for the CEO.
Stakeholder Management: Acting as the primary point of contact for high-level officials across Whitehall and the financial sector.
Office Leadership: Line-managing the administrative team within the CEO’s Private Office to ensure operational excellence.

Top Candidate Requirement: A minimum of 3 years of experience managing a Private Office or supporting Board-level executives. Absolute discretion and the ability to work in a high-pressure, market-sensitive environment are mandatory.
