About The Role

As Head of Product for Platform, you are responsible for the strategic direction and effective execution of ENSEK's Platform product portfolio. The Platform underpins every product team in the organisation and is the foundation on which great products are built. Your focus will be on driving a unified set of well‑maintained software libraries and foundational ‘features’ that eliminate complexity and accelerate delivery.

Key responsibilities

• Own and deliver clear OKRs in partnership with engineering and commercial leaders.
• Treat internal engineering teams as primary customers, shaping platform priorities based on their needs and workflows.
• Define and own the Platform product strategy and roadmap, balancing near‑term delivery with long‑term architecture.
• Drive evidence‑based prioritisation, making clear decisions on what to improve, replace, or retire—including defining the future of the Workflow Engine at the core of billing and payments.
• Work closely with engineering leadership to align delivery, manage tech debt, and coordinate platform evolution across dependent teams.
• Lead build‑vs‑buy‑vs‑partner decisions with strong technical and commercial judgement.
• Own ENSEK’s AI platform strategy, enabling safe, scalable adoption of agentic AI and productivity tooling across product and engineering teams.
• Own “API as a Product”, accountable for external developer experience including documentation, consistency, tooling, SDKs, and API pricing and packaging.
• Own the end‑to‑end new customer onboarding platform, including configuration tooling, environment provisioning, and automation to reduce time‑to‑onboard.
• Define and own platform quality outcomes (availability, reliability, security), including production KPIs.

Key outcomes

• Measurable improvement in external API developer experience (e.g., time‑to‑first‑call, API NPS, support ticket reduction) with definition and implementation of an API pricing and packaging model in partnership with Product Marketing.
• Reduction in time‑to‑feature for product teams related to platform investment from areas such as Workflow engine, end‑customer communication and document management frameworks, IAM, API as a Product approach and agentic frameworks.
• Increase in platform adoption and consistency of use across engineering teams.
• Reduction in new customer time‑to‑onboard, with a target trajectory from months to hours through investment in configuration tooling and process automation.
• Reduction in time and effort required to provision and maintain customer environments (e.g., UAT, test, production), with measurable progress toward self‑service.

Experience required

• Demonstrable experience as a product leader, ideally within platform, developer tooling, or infrastructure‑adjacent product domains.
• A strong technical background—although you do not need to write production code, you should be deeply comfortable engaging with engineering and understanding trade‑offs.
• Proven ability to make objective, data‑informed decisions about product direction and to challenge existing solutions and advocate for change.
• Strong people‑management experience with a track record of developing product managers and building high‑performing product teams.
• Track record of defining and delivering complex technical products with clear value propositions for both internal and external stakeholders.
• Ability to operate across both strategic and tactical levels—setting long‑term direction while remaining hands‑on enough to unblock teams and maintain delivery momentum.
• Understanding of P&Ls, budget setting/tracking, with the ability to create sound business cases.
• Ideally, an educational background of a degree in Computer Science, Engineering, Product Management or equivalent.

Company Benefits

• 25 days’ holiday + bank holidays.
• Option to buy or sell 5 extra annual leave days per year.
• Vitality Health Insurance, including private healthcare, virtual GP access, mental‑health support and wellbeing perks (50% off gym memberships – Virgin Active, Nuffield, PureGym).
• Pension with 5% matched contribution.
• Regular team‑wide and company‑wide events.
• 2 volunteering days per year to give back.
• Remote‑first working environment with offices in London and Nottingham.
