Senior Finance Analyst (First Mover) | Series B B2B SaaS | Remote-First (UK-Based)

The Client

Harmonic is delighted to be exclusively representing a Series B B2B SaaS scale-up whose technology powers some of the world's most recognised brands. Having reached roughly $20m ARR and profitability following a $60m Series B raise, the business is now in an AI-powered growth phase, and Finance is a priority function on that agenda. It is a genuinely brilliant company to be part of: technically sophisticated, remote-first, and deeply AI-forward, with an internal team actively enabling every function with AI.

The Role

This is a deliberately broad, high-exposure role for a recently qualified accountant making their first move out of practice and into industry, someone who wants to do far more than close the books. Reporting to and coached by the Finance Manager, with regular exposure to the VP of Finance and wider leadership, you will share the delivery load across the full finance cycle, take full ownership of a set of financial operations, and be the hands-on engine for AI and automation across the function. It is a rare chance to build genuine finance-transformation skills at one of the most AI-forward companies you could join at this stage of your career, with a clear path to grow into a finance manager role over the next 12-18 months.

Key Responsibilities

• Run the delivery engine across the finance reporting cycle: journals, consolidation and first-draft management accounts, alongside billing, invoicing and payment approvals.
• Support revenue recognition and investor and bank reporting.
• Take full ownership of key financial operations, including expenses and credit control, and oversee the Bookkeeper's day-to-day transactional work.
• Design and build automations across your delivery areas, developing and owning AI-enabled finance processes end to end.
• Business partner with delegated cost-centre and budget holders, helping them stay within budget and get the most from their spend.
• Exposure to FP&A and commercial finance such as budgeting, cash-flow forecasting and planning.
• Prepare the schedules and underlying data behind UK and US tax compliance, and act as a key point of contact through the annual audit.

Essential Experience

• Newly qualified accountant (ACA, ACCA or equivalent), making a first move out of audit or practice.
• Big 4 trained
• High attention to detail, strong problem-solving skills, and a genuine eye for process improvement.
• Excellent communication and stakeholder-management skills.
• Comfortable in a less structured, remote-first environment, and happy learning on the job.

Desirable Experience

• An efficiency-focused mindset with some demonstrable experience of improving or automating processes. You do not need substantial AI-automation experience; that will be taught, but you should be curious about where technology can make finance better.
• Exposure to a fast-paced, scaling business.

Salary: £60,000 - £65,000 + equity
