CTO

We’re building something genuinely rare: a financial brand designed for the mass affluent, the professionals, entrepreneurs and ambitious savers that traditional banks have systematically underserved for decades.

We exist to make managing wealth simpler, smarter and more human, treating every client’s wealth with the same care as if it were our own.

We have over £7 billion in client deposits, a fresh funding round and a place on the Future Fifty, the UK’s top pre-IPO companies. The momentum is real.

This is an engineering ownership role, not a delivery management role. You will define how Monument’s Savings product is built, scaled and evolved, leading a team of engineers, setting the technical direction and making the architectural calls that underpin a product trusted by tens of thousands of clients.

For the right engineer, this is a rare opportunity: technical leadership at a pre-IPO challenger bank, on a core product in a segment nobody has properly cracked, with genuine commercial backing and the mandate to build it right from day one.

• Own the technical roadmap for Monument’s Savings infrastructure, designing for growth, resilience and long-term maintainability as client volumes and deposit balances increase.
• Partner with Product and Design to architect and ship new Savings features, from technical scoping and design through to production release and post-launch monitoring.
• Identify, evaluate and implement AI-powered tooling that meaningfully accelerates design, development and code review, raising team output without compromising quality or security standards.
• Systematically improve the capability and capacity of the engineering team through structured mentoring, code review, better tooling and removal of delivery friction.
• Set and maintain the architectural standards, coding conventions and quality bar for the Savings engineering team, ensuring consistency across the codebase and rigour in every release.
• Line manage a team of engineers with a focus on performance, growth and retention, running regular one-to-ones, setting clear expectations and building a high-trust environment where people do their best work.
• Ensure the Savings product is built and maintained in line with Monument’s regulatory obligations, including operational resilience requirements, UK GDPR data handling standards and the principles of FCA Consumer Duty as they apply to product design and delivery.
• Act as a trusted technical voice to the CTO, surfacing risks early, contributing to engineering-wide decisions and representing Savings in technical forums.

• Monument is growing fast. Your architectural decisions will determine whether the Savings product handles that growth with confidence or becomes a source of operational and regulatory exposure.
• Experimentation and compliance must move together. You will need to build delivery cadence within constraints and develop the judgement to know where the line is.
• The best engineers are not managed by authority. You will need to build genuine technical credibility with your team and earn trust as someone who raises the bar, not just holds it.
• There is a lot of noise around AI in engineering. Your job is to cut through it: identify what actually improves output, implement it rigorously and build it into how the team operates day to day.

• Bias to Action. Make decisions with the information available. Do not wait for perfect conditions. Ship, learn, iterate.
• Radical Ownership. Accountable for the health, performance and output of the Savings engineering function, not just your own code.
• Challenge with Intent. Push back when the evidence supports it. Advocate for technical quality even when it is commercially inconvenient.
• Intellectual Humility. Let data and results guide architectural decisions. Adapt when evidence changes, even when it means revisiting previous calls.
• Low ego, high standards. Confident in technical convictions, open in approach, collaborative by default.

• Proven experience as a Tech Lead or Lead Engineer…
