Job Description

Finance Manager | VC-Backed SaaS Scale-Up | Remote-First (UK-Based)

The Client

Harmonic is delighted to be exclusively representing a Series B B2B SaaS scale-up who are powering live digital experiences for some of the world's most recognised brands.

Now entering a new phase of AI-powered growth, they have steadily expanded year-on-year, achieving $20m ARR and profitability following a successful $60m Series B raise. While the early years focused on deep product development, the business has since entered an exciting commercial growth phase, investing heavily in its go-to-market strategy and positioning itself as an AI-driven solution poised to unlock major opportunities in the next cycle.

It's a genuinely brilliant company to be part of: technically sophisticated, culturally grounded, and led by people who care deeply about autonomy, trust, and impact.

The Role

Reporting directly into the VP of Finance, who is a highly regarded, approachable leader who provides real mentorship, this is a career-building opportunity for a smart, hands‑on finance professional ready to step up into a broader Finance Manager role within a SaaS environment.

You’ll join a small, high‑calibre team where everyone collaborates on improvement and transformation. There’s genuine scope to shape how finance operates, from process design to system improvements and cross‑functional business partnering.

This is an ideal step up for a Financial Accountant who has a strong understanding of how AI and tech‑enabled automation is the future of finance and has demonstrable experience within a scale‑up / fast‑paced environment.

Key Responsibilities

• Own financial accounting and reporting, leading month‑end and year‑end close with accuracy and efficiency.
• Oversee finance operations, AP, AR, payroll, and ledger management, ensuring the right tools, partners, and systems are in place.
• Drive process improvement and automation, embedding AI and data‑led efficiency within finance workflows.
• Partner with department leads to manage budgets, improve ROI, and provide clear insight into spend.
• Manage UK VAT, US sales tax, and compliance with external advisors, leading the annual audit process.
• Ad hoc project support.

Essential Experience

• ACA qualified (Big 4 or Top 10 trained) with 5+ years total experience.
• A blend of strong technical grounding and some exposure to a fast‑paced scale‑up environment.
• A process‑oriented mindset with curiosity for automation, data, and modern finance tooling.
• Confident communicator.

Desired Experience

• B2B SaaS, or SaaS more broadly.
• Will consider exceptional CIMA / ACCA candidates.
• Self‑starter: thrives in environments where ownership, proactivity, and autonomy are valued.

Salary

£70,000 - £80,000 + equity

Location

Remote‑first (occasional London meet‑ups), with an office that you are welcome to work in.

Start Date

ASAP, but will consider exceptional candidates on 3 months' notice.

At Harmonic, we are dedicated to fostering an inclusive and equitable workplace. We actively welcome applications from individuals of all backgrounds and assure you that every candidate will be thoughtfully considered for the roles we represent, without regard to race, religion, gender expression, disability, or sexual orientation.
