About Abselion
Abselion is a Cambridge University spin-out transforming how scientists measure biomolecules. Our Amperia platform uses proprietary Redox Electrochemical Detection (RED) technology to quantify His-tagged and Fc-containing proteins, host cell proteins and AAVs directly from crude samples in minutes, without purification, and without specialist training.

We work with protein expression teams, antibody discovery groups and AAV development teams in academia, biotech and pharma across the globe who are tired of waiting days for analytical results that should take minutes. We are building the commercial team that will take Amperia from early adopters to a widely recognised standard in the field.

We are a team who care deeply about the science, move quickly, and believe that the best commercial outcomes come from genuinely understanding and helping customers solve real problems.

The Role
This is a hands-on, execution-focused role at the centre of Abselion's day-to-day financial operations. The Finance Manager will take ownership of the finance function's operational workload—ensuring invoices go out on time, cash is tracked, suppliers are paid, month-end closes cleanly, and nothing falls through the gaps.

The role exists to give the CEO back their time. You will be the person who makes the financial engine run reliably, and who builds the processes and habits that let it keep running as the company scales. In the first 90 days, the priority is getting under the bonnet of the current setup, establishing clean cadences, and making meaningful improvements to how the finance function operates day to day.

This is not a reporting or advisory position. It suits someone who is energised by execution, takes pride in accuracy, and is comfortable being the person who just gets things done.

Key Responsibilities
Financial operations

• Own the full invoicing cycle—raise invoices when orders ship, manage collections, and keep AR current.
• Run accounts payable—match purchase orders to invoices, manage payment runs, maintain supplier relationships.
• Maintain cashflow visibility on a rolling basis so leadership always has an accurate picture.
• Close month-end in collaboration with external accountants, on time and to a consistent standard.
• Keep reconciliations current and the books clean and audit-ready.

Reporting & controls

• Produce regular budget vs actual analysis and flag variances to the relevant leads.
• Support COGS, inventory and margin tracking for instruments and consumables.
• Maintain the compliance calendar and ensure statutory obligations are met without prompting.
• Identify process gaps and implement practical improvements as the company grows.

Cross-functional collaboration

• Work with Sales and Operations to ensure orders, deliveries and billing are fully aligned.
• Ensure ERP and CRM data is accurate and supports clean financial reporting.
• Support grants, R&D tax credits and funder reporting where applicable.

Experience & Skills
Essential

• Qualified or part-qualified accountant (ACA / ACCA / CIMA), or equivalent experience in a hands-on finance role.
• Proven track record in an execution-focused position: Finance Manager, Financial Controller, Senior Accountant or similar.
• Strong working knowledge of AR, AP, month-end close, cashflow management and reconciliations.
• Highly organised and detail-oriented, with a track record of delivering to deadlines without being chased.
• Comfortable working autonomously in a small team where the scope of the role will evolve.
• Clear and direct communicator with non-finance colleagues and senior leadership.

Desirable

• Experience in a start-up or scale-up environment.
• Familiarity with manufacturing, hardware or consumables businesses, including inventory and COGS tracking.
• Experience supporting order-to-cash and procure-to-pay workflows.
• Working knowledge of ERP or CRM systems that interface with finance.
• Exposure to UK statutory reporting, R&D tax credits or grant administration.

What We Offer

• £50,000–£65,000 base salary, dependent on experience.
• Share option scheme—everyone at Abselion has equity in what we're building.
• A role with genuine ownership and direct impact from day one.
• A close-knit, talented team working on technology that matters.
• The opportunity to grow with the company as we scale.
