Location:
Stratford, London office
- Hybrid working – occasional travel to all current & future Affinia office locations.

Affinia is the UK’s largest purpose-led, purpose-built Accountancy firm, focused on building stronger, more valuable relationships. With over 1600 colleagues across the East, South East, London and the Midlands, we are dedicated to supporting our clients, colleagues and communities.

We advise businesses, public sector organisations, charities and individuals throughout the UK and internationally across six Service Lines
- Accountancy & Advisory, Tax and Planning, Audit & Assurance, Corporate Finance, Payroll and Corporate Recovery. Our team also offer in-depth sector expertise across a number of sectors, ensuring our clients receive the best short to medium and long-term advice, tailored to them. We are committed to delivering excellence in every aspect of our work, adapting to the evolving technology and regulatory landscape while consistently exceeding client expectations.

Our people are our most valuable asset. We are therefore committed to supporting our colleagues throughout their professional development, providing guidance and training at whatever stage of their career they join us.

We are looking for a Senior Project Manager to take ownership of multiple projects across a growing and fast-moving portfolio. You will run them end to end: scope, plan, budget, risks, delivery and benefits. You will be trusted to make the call on the day to day and to bring the right decisions to the right forum at the right time.

You will join the Innovation and Change team, working closely on the design of the firm's future operating and technology landscape. That means partnering with senior business stakeholders on transformation and AI initiatives and working alongside the Acquisition Integration team so the two streams move as one programme rather than two. You will have real input into what gets built, in what order, and why.

On any given week you might be shaping a business case, chairing a steering group, unpicking a data issue with a vendor, or helping a service line head think through what AI actually changes for their team. You will represent Innovation and Change in senior stakeholder forums and act as a point of contact across the portfolio. You will also raise the bar for how projects are run here: better templates, cleaner reporting, sharper governance, and coaching for less experienced colleagues.

You will be working with internal teams and external partners across technology, integration, data, AI and business change. The work is visible at Board level, the pace is quick, and the ambition is high. If you want a role where your judgement shapes the answer rather than just tracks it, this is it.

• Portfolio breadth, not a single project. You will hold the view across several work streams at once.
• Genuine influence on future state design, not delivery of someone else's blueprint.
• A firm growing through acquisition, so integration and transformation run side by side.
• Permanent, hybrid, with the scope to grow as the portfolio grows.

Delivery

• Own a portfolio of concurrent projects end to end: scope, plan, budget, resource, risk and benefits.
• Set each project up properly at the start: business case, success measures, governance and a plan people can be held to.
• Track delivery against milestones and budget. Report status…
