Finance Accountant (SaaS)

We’re hiring a Finance Accountant to join our small finance team. You’ll report to the Associate Finance Director and take real ownership of the day-to-day accounting work that keeps zeroheight running accurately – from month‑end close and SaaS billing to global tax compliance. This role is ideal for someone who is detail‑oriented, proactive in improving processes, and keen to build their experience in a fast‑paced SaaS environment.

Your impact

You’ll be responsible for running the core accounting operations day to day:

• Delivering a reliable monthly close
• Ensuring billing runs smoothly

There is scope to improve existing processes, particularly as we explore automation and AI tools within finance, and we’re looking for someone who can contribute ideas and help implement them.
