  • About the Role

  • Senior Portfolio Officer
    Location: Teddington (Hybrid – typically 2 days per week on site, with flexibility to reduce to 1 day depending on business need)

    Shape Change at the Heart of NPL
    The Portfolio Office sits at the centre of NPL’s change agenda. We provide integrated oversight, governance, prioritisation, assurance and insight across NPL’s internal and external portfolios — enabling the right change to be delivered at the right time, in the right way, with the right support.
    We are now seeking a Senior Portfolio Officer to take a visible, influential leadership role within this model. This is not a passive or purely coordinating PMO role — it is a hands on, delivery facing leadership position where your judgement, challenge and assurance directly influence outcomes.

    Operating within a Hub and Spoke model, you will be:
    Based centrally within the Portfolio Office (the Hub), and
    Embedded within a major programme (a Spoke), flexing to where senior governance, assurance and decision support are most needed.

    You will be expected to spend around two days per week on site in Teddington, building strong relationships and providing effective challenge face to face. This may reduce to one day per week over time, but candidates must be comfortable with hybrid working and flexibility.

    What You’ll Be Doing

    Lead Governance & Assurance
    You will take ownership of assurance activity across programmes and projects, ensuring it is robust, proportionate and genuinely adds value.
    Lead health checks, start up reviews, stage gates and deep dive assurance activity
    Ensure governance cycles run effectively, with clear, high quality evidence presented to boards and committees
    Provide independent, constructive challenge to test readiness, controls and delivery confidence
    Capture lessons learned and embed them across the portfolio

    Operate as a Senior Leader
    This role requires demonstrable leadership. You’ll be expected to set direction, influence outcomes and act as a trusted authority — not simply work within existing structures.
    Act as a senior point of contact for delivery teams on PPM frameworks, standards and assurance expectations
    Provide leadership and direction to Portfolio Office colleagues when embedded in programmes
    Communicate confidently and credibly with senior sponsors, executives and board level stakeholders
    Be comfortable challenging assumptions and decisions in a constructive, evidence based way

    Manage Risk, Dependencies & Value
    You’ll play a key role in ensuring NPL understands where its real risks and value lie.
    Monitor and escalate major risks, issues and dependencies surfaced through governance and assurance
    Ensure RAID information is credible, consistent and aligned to agreed standards
    Provide informed commentary on benefits, outcomes and value delivery
    Champion a culture of benefits realisation and value led decision making

    Provide Financial & Portfolio Insight
    When embedded within programmes, you’ll support financial discipline and portfolio level insight.
    Support budget tracking, forecasting and financial inputs
    Provide analysis to inform prioritisation, sequencing and resource planning
    Contribute to evidence based decision making at portfolio level

    Drive Continuous Improvement
    You won’t just operate the system — you’ll improve it.
    Lead enhancements to governance frameworks, assurance approaches and portfolio processes
    Benchmark against external good practice to keep NPL’s standards credible and effective
    Actively shape how the Portfolio Office evolves as a Centre of Excellence

  • About You

    Background in complex, multi stakeholder or public sector organisations
    Professional qualification or equivalent experience (e.g. APM, MSP, P3O)
    Experience supporting portfolio prioritisation and benefits led decision making
