Head of Finance

Location: London, UK / Flexible Hybrid
Department: Finance
Reports to: Chief Financial Officer

We are building next-generation GPU cloud infrastructure.

NexGen Cloud is the company behind Hyperstack, a high-performance cloud platform powering compute-intensive workloads. Our customers range from AI-native startups to enterprise and research teams running complex, large-scale models.

We’re scaling quickly — both technically and commercially — and building the financial infrastructure to support that growth.

This is not a steady-state finance role. This is about building something that can keep up with a business moving at pace.

This is a senior leadership role sitting directly below the CFO.

You’ll be responsible for shaping and executing the financial operating model of the business — building structure, improving processes, and ensuring the company has the financial clarity it needs to scale properly.

The role spans four key areas: financial operations, modelling and forecasting, board reporting, and business partnering.

You’ll need to be comfortable switching gears — one minute fixing a broken process, the next supporting strategic decision-making at board level.

• Improve and scale core finance processes, with a strong focus on automation and efficiency
• Identify and resolve operational debt across finance systems and workflows
• Strengthen the link between financial data, revenue drivers and business KPIs
• Partner with the CFO to optimise systems (including NetSuite) and data infrastructure

• Own and evolve the three-statement financial model as the business scales
• Develop robust, driver-based forecasting capability
• Lead and oversee FP&A output, ensuring quality and consistency
• Support strategic planning, scenario modelling and investment decisions

• Own the preparation of board-level financial reporting
• Act as a critical review layer (‘four-eyes’) on financial outputs
• Build and improve internal reporting to drive better decision-making
• Support investor and stakeholder reporting requirements

• Embed budgeting and financial ownership across departments
• Act as a trusted advisor to senior stakeholders across the business
• Represent finance at leadership level when required
• Support and develop FP&A capability within the team

• Proven experience in a senior finance role within a high-growth or scale-up environment
• Strong track record in building and improving finance processes and systems
• Experience developing and owning complex financial models and forecasts
• Exposure to board-level reporting and senior stakeholder engagement

• Strong analytical thinking with the ability to turn complex data into clear insight
• High level of data literacy and comfort working with large datasets
• Ability to operate both strategically and hands-on
• Confident communicator with both technical and non-finance stakeholders

• Experience in cloud, infrastructure, or technology-led businesses
• Familiarity with ERP systems such as NetSuite
• Experience scaling finance functions in a fast-moving environment

• Competitive salary + discretionary bonus
• 25 days holiday + public holidays
• Flexible hybrid working
• High-impact role with direct CFO and board exposure
• Real ownership of building a finance function at scale

We’re not just adding headcount — we’re building capability.

This role sits at the center of that. You’ll have the opportunity to shape how finance operates in a business that’s scaling quickly, solving complex problems, and operating in one of the most relevant sectors in tech.

If you want a role where you can genuinely influence how a company grows — this is it.
