• Reviewing junior team members' work and helping support their development
• Building strong, long-term relationships with clients

• £60,000-£65,000 salary
• Hybrid working - only two days per week required in the office
• Flexibility around working patterns, including part-time arrangements where practical
• A 35-hour working week, with core hours of 10am to 4pm
• High-quality, varied work without the typical Big Four lifestyle
• Strong internal progression, mentoring and structured development at Assistant Manager, Senior Manager and Director level
• Scope to develop a specialist area over time, whether that is capital allowances, R&D, international tax, employee rewards or another area of interest
• A collaborative office culture with excellent staff retention and a genuine one-team feel
• Easy access from High Wycombe station, just a short walk from the office
• 25 days' annual leave, pension, life assurance, flexible benefits, profit share and discretionary bonus

What they are looking for

This role would suit a Corporate Tax Senior, Assistant Manager or Manager who is looking for more responsibility, broader exposure and a clear long-term path.
