Location: Hybrid – Remote with weekly on-site presence within the M25.

An Aker Enterprise Architect (Sourcing Strategy) is primarily a client strategy, management, and growth role, expected to be 90% or more of the time across one or more client assignments.

You will be part of the client leadership team as the technical lead for assigned projects/services, supporting the Aker Client Programme Director, Aker Client Account Director and the Aker and client delivery teams to ensure we deliver against all client deliverables and payment milestones.

This is a senior client-facing role supporting a major re-procurement and insourcing programme for a national public sector capability. The Aker Enterprise Architect (Sourcing Strategy) will be responsible for leading the discovery, mapping and planning of a complex service and technical landscape currently operated by a single incumbent supplier - strategically transitioning to a disaggregated sourcing approach (client and supplier). The role requires broad enterprise architecture experience in a public sector client and multi-supplier environment, and the ability to lead a multi-disciplinary team across infrastructure, application, data, and security domains.

The successful candidate will work within a blended delivery environment comprising customer stakeholders, incumbent suppliers, and commercial partners. They will provide strategic input into procurement structuring, supplier evaluation, and technical assurance, ensuring alignment with programme objectives and service continuity.

Aker is a fast-growing business, so for any remaining % of time when not on client work, it is contributing to the future success of Aker by helping develop capabilities and supporting the other functions such as Sales and Technology and always looking to help grow existing accounts.

Key Responsibilities

• Lead the strategic technical sourcing aspects of a complex re-procurement and insourcing programme for a public sector organisation.
• Conduct deep discovery and mapping of incumbent supplier services, platforms, and technology stack.
• Analyse how services fit within the overall scope of the contract, including legacy and transformation elements.
• Lead the development of high-quality artefacts including service maps, capability matrices, and evaluation frameworks.
• Provide architectural input into procurement documentation (PQQ, RFI, RFP), including advising on how the procurement could be structured or carved up.
• Support the creation of supplier briefing packs, evaluation rubrics, and scoring models.
• Collaborate with commercial, legal, and operational stakeholders to ensure procurement and insourcing strategy.
• Lead and mentor a team of architects (security, infrastructure, integration, application) and systems analysts.
• Operate effectively within a blended delivery team, which includes customer stakeholders, incumbent suppliers, and commercial support. This requires strong collaboration, adaptability, and the ability to navigate multi-party dynamics while maintaining delivery focus.
• Support stakeholder workshops, onboarding plans, and capability building across the programme.

Expanded Procurement Responsibilities

• Procurement and Insourcing Structuring
  Advise on how services and capabilities can be logically grouped or modularised for tendering, identifying architectural boundaries, dependencies, and integration points that inform how the procurement could be shaped to optimise delivery, competition, strategic alignment whilst ensuring service stability.

  Embed architectural principles and solution design requirements into documentation across all procurement stages (PQQ, RFI, RFP) and insourcing transition preparation. This includes:
• Service delivery model responsibilities
• Defining mandatory and desirable technical capabilities

• Innovation and interoperability assessments
• Risk and assurance indicators

• Mapping Incumbent Technology to Procurement and Insourcing Transition Scope
  Capture and analyse the incumbent supplier’s technology stack, service delivery model, and operational dependencies. This mapping exercise will inform the future architecture and procurement and insourcing scope, ensuring continuity or improvement in service delivery.
• Option Analysis and Recommendations
  Support solution option analysis and provide architectural recommendations that influence procurement decisions. This includes trade-offs between bespoke vs. COTS solutions, hosting models (cloud vs. on-prem), and integration strategies.
