Copilot/LLM Prompt Engineer - SC/DV Cleared Microsoft Copilot | Prompt Engineering | AI Safety | M365 Agents

Hybrid Working | Secure Government Environment
SC or DV Clearance required

We are supporting a secure government organisation building out its AI and Copilot capability and are looking for a Prompt Engineer with experience across Microsoft Copilot, LLM prompting and low-code/no-code agent delivery.

This is a hands-on role focused on designing, testing and governing prompts and AI agent workflows within Microsoft 365 Copilot, Copilot Studio and approved AI platforms. The environment is highly regulated and requires a strong focus on AI safety, assurance and controlled implementation rather than experimentation.

The organisation is open to both:

  • experienced AI/Prompt Engineering specialists,
  • or more junior technical profiles with demonstrable experience working with prompting, M365 Copilot, AI agents or workflow automation.

The team is particularly interested in candidates who can combine:

  • prompt engineering capability,
  • practical delivery,
  • stakeholder engagement,
  • and the ability to help non-technical users adopt and safely use AI tooling.

This role will work closely with delivery, product and operational teams to translate business requirements into safe, effective prompt-based solutions that can be managed and owned internally over time.

Key responsibilities
  • Design, develop and maintain prompts for M365 Copilot and approved LLM platforms
  • Build and support low-code/no-code AI agents using Copilot Studio and related tooling
  • Create reusable prompt libraries and approved prompt patterns
  • Conduct structured prompt testing, regression testing and assurance validation
  • Ensure prompts align to AI safety, governance and organisational policy requirements
  • Support users in refining requirements and translating them into prompt-driven solutions
  • Work closely with delivery and operational teams within Agile environments
  • Support skills transfer and internal capability development across AI and prompting practices
  • Document testing outcomes, assurance evidence and governance controls
Required experience
  • Experience working with Microsoft Copilot, Copilot Studio or enterprise LLM tooling
  • Hands-on prompt engineering capability
  • Understanding of AI safety and model behaviour risks
  • Experience designing reusable prompts, templates or agent workflows
  • Experience with low-code/no-code automation or AI agents
  • Strong stakeholder engagement and requirement gathering skills
  • Experience operating within regulated, secure or controlled environments
  • Understanding of testing and validation approaches for prompts and AI outputs
Desirable experience
  • M365 Agents/Agent frameworks
  • Azure OpenAI/AI Studio
  • AI governance or assurance experience
  • Prompt libraries/reusable AI workflows
  • Agile delivery environments
  • Government or public sector experience
  • Python, Power Platform or automation exposure
  • Experience supporting adoption and user enablement
Clearance
  • Active SC Clearance required
  • Enhanced SC or previously held enhanced SC highly desirable
  • DV Clearance beneficial
Additional information

The organisation is actively building long-term AI capability and is particularly interested in individuals who can contribute to knowledge transfer and help establish sustainable internal AI practices over time.

Enhanced SC-cleared candidates with genuine hands-on Copilot and prompt engineering capability are extremely difficult to secure in the current market, so interview slots are likely to move quickly for suitable profiles.
