We are building an alternative to traditional advisory firms, focused on clarity over complexity, outcomes over hours, and practical advice delivered at pace for CFOs making high‑consequence decisions.

What You’ll Do

  • Own the end-to-end financial and tax‑technical delivery of R&D tax claims, including cost identification, apportionment, computation, CT600 adjustments, and HMRC submission.
  • Analyse client cost bases to identify and quantify qualifying direct and indirect R&D expenditure under the merged RDEC scheme and the Enhanced R&D Intensive Support (ERIS) regime.
  • Lead detailed cost reviews with finance teams, interrogating trial balances, payroll data, subcontractor arrangements, cloud computing and data licence costs, and overhead allocation methodologies.
  • Navigate the complexities of the merged scheme, including the overseas expenditure restrictions, PAYE/NIC cap mechanics, subsidised expenditure rules, and claim notification requirements.
  • Prepare and review robust claim reports and supporting schedules that withstand HMRC enquiry, including the Additional Information Form (AIF).
  • Stay ahead of legislative and case‑law developments, advising clients on their practical impact and adjusting claim strategies accordingly.
  • Work alongside the Technology & Science team to ensure qualifying activity narratives and cost schedules are fully aligned.
  • Manage HMRC enquiries and voluntary disclosures, acting as the primary tax‑technical point of contact.
  • Develop and maintain trust‑based senior client relationships, advising CFOs, Group Tax Directors, and Financial Controllers.
  • Provide leadership, coaching, and technical oversight to junior team members on costing methodology and tax compliance.
  • Actively adopt, build, and improve AI‑driven tools and workflows for cost analysis, claim computation, and compliance, in line with Unity’s culture of embedding AI across all workstreams.
  • Contribute to business development, pricing strategy, thought leadership, and go‑to‑market initiatives.

What You Bring

  • Deep expertise in the tax and financial mechanics of UK R&D tax relief, including RDEC, ERIS, cost categorisation, and CT600 treatment, ideally gained in a Big 4, top‑tier, or specialist R&D advisory firm.
  • Proven ability to navigate complex corporate cost structures, group recharges, subcontractor chains, and multi‑entity claim scenarios.
  • Strong working knowledge of HMRC’s R&D compliance framework, enquiry processes, and the Additional Information Form.
  • Excellent project management skills with the ability to manage multiple concurrent claims across varying industries and deadlines.
  • Exceptional stakeholder management, with confidence advising senior finance and tax leaders.
  • ACA, CTA, ATT qualified or equivalent practical experience.
  • A genuine enthusiasm for AI and technology, with a willingness to adopt, experiment with, and help build AI‑enabled advisory tools.
