Senior Manager - R&D Tax

Unity Advisory is a pure-play, experience-led CFO advisory firm providing integrated finance, commercial, tax and deals support. We are free from audit conflicts and AI-enabled by design, combining deep technical expertise with automation, analytics and AI built into the delivery of every engagement. 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.

The Role

We’re looking for a technically curious, scientifically literate Senior Manager to join our fast-growing R&D tax practice. This role is the technical engine of our R&D advisory. You’ll work at the intersection of innovation and tax, engaging directly with engineers, scientists, product teams, and CTOs to identify, interrogate, and articulate the qualifying R&D activities that underpin every claim.

Across a diverse portfolio, from AI-native startups and biotech firms to advanced manufacturing groups, you’ll lead technical interviews, author the scientific and technological narratives that form the backbone of claim reports, and ensure every qualifying project is captured and clearly articulated against the DSIT Guidelines and HMRC’s competent professional test. Working closely with Partners and the Tax & Costing team, you’ll shape how we leverage AI to improve technical documentation, knowledge capture, and narrative quality.

This is not a traditional report-writing role. You will be expected to bring genuine scientific curiosity, engage critically with complex R&D programmes, and actively build or improve AI-driven workflows that raise the standard of technical documentation and client delivery.

What You’ll Do

- Lead technical discovery across client engagements, conducting in-depth interviews with engineers, scientists, product managers, and R&D leaders to surface qualifying activities.

- Author and review compelling, HMRC-defensible technical narrative...
