Job description

Who are OnCommerce?

OnCommerce is a global selling platform that powers a growing network of retail channels, including:

• OnBuy- The only marketplace in the world to give customers instant Cashback on everything
• easyShop- An all-new marketplace created in collaboration with the easy® family of brands
• Comet- The iconic UK tech brand making its return later this year

OnCommerce is growing fast, launching new brands and scaling to power the future of ecommerce.

Be Part of the Story

OnCommerce is constantly evolving. Everyone here plays a hands‑on role in shaping what comes next, building brands that make an impact across global markets. There’s no red tape or rigid corporate structure; just smart people taking ownership and figuring things out as we build something big together. The pace is fast, priorities shift, things aren’t always perfectly set up, and you’ll often need to get stuck in and solve problems. But if you thrive in that kind of environment, you’ll have real influence, real ownership, and the chance to grow with a rapidly scaling business.

About the Role

Financial Planning & Analysis Senior Manager / FP&A Senior Manager will own the full FP&A cycle, acting as a strategic partner to various business units and reporting directly to the CFO. This role is critical in connecting different business units to key parts of the financial model, driving commercial insights, and supporting long‑term strategic planning.

Key Responsibilities will encompass:

• FP&A Cycle Ownership: Lead the budgeting, forecasting, and variance analysis processes, ensuring alignment with strategic goals.
• Business Partnering: Collaborate with department heads and the senior leadership team to provide financial insights and support decision‑making.
• Financial Modelling: Own the company financial model to support budgeting, scenario planning, fund raising and investment decisions.
• Reporting: Prepare and present financial reports, including contributing to board packs, shareholder updates and ad‑hoc analysis.
• Process Improvement: Identify opportunities for automation and efficiency improvements within the FP&A function.
• Software Implementation: Evaluate and implement FP&A software solutions that work alongside NetSuite to enhance planning and reporting capabilities.

Required Skills and Experience:

• CIMA, ACA, ACCA, or equivalent finance qualification.
• Experience: 7–10+ years of experience in FP&A, with a proven track record of leading financial planning processes and influencing strategic decisions.
• Technical Skills: Financial modelling and advanced Excel skills.
• Analytical Skills: Strong analytical and problem‑solving skills, with the ability to interpret complex data and provide actionable insights.
• Communication: Excellent communication and presentation skills, with the ability to engage and influence senior stakeholders, including the CFO, CEO, Directors and Heads of function.
• Multi‑entity / multi‑currency experience.
• Eligibility to work in the United Kingdom.

Desirable but not essential Skills and Experience:

• Familiarity with NetSuite and FP&A software.
• Knowledge of e-commerce and online marketplace dynamics.
• Proficiency in SQL: ability to self‑serve data from financial and operational systems would be a bonus.

The salary on offer for this role is £80,000-£90,000 per year depending on experience.

We also offer the following benefits:

• Company Equity- In return for helping us to grow, we’ll offer you company equity, meaning you own a piece of this business we are all working so hard to build.
