Senior Manager

Overview

Startup Accountancy is a modern, startup-native practice built to challenge the traditional accountancy model. We’re looking for a Senior Manager to take on day-to-day leadership of client delivery, helping us scale a practice that combines technical excellence with startup speed and clarity.

You’ll manage a portfolio of clients, lead and mentor team members, and ensure our processes run smoothly. You’ll work closely with the Head of Client Services and founders, giving you direct exposure to the leadership of a fast-growing practice and a clear pathway to progress into more senior roles as we scale.

This is an opportunity to step out of the bottlenecks of traditional firms and into a role where you’ll have visibility, influence, and the ability to shape how modern accountancy is delivered.
