Head of Engineering

About Moneybox

At Moneybox, our mission is to give everyone the means to get more out of life. We're guided by our belief that wealth isn't about the money, it's about the means to more - more freedom, opportunities, possibilities, and peace of mind. Moneybox is an award‑winning wealth management platform, helping over one and a half million people build wealth throughout their lives, whether they’re saving and investing, buying their first home, or planning for retirement.

We are looking for a Head of Engineering to help us scale our engineering capability without compromising product quality, service reliability or regulatory standards.

This is a senior, hands‑on engineering leadership role. We are looking for someone who can lead through technical depth, strong execution and pragmatic decision‑making. The ideal candidate is comfortable designing and helping build complex, high‑risk functionality where the margin for error is small. They should be able to operate confidently in a regulated financial services environment and help teams move quickly without creating unnecessary complexity.

A major focus of this role will be technical leadership across Moneybox’s payments, money movement, interest and fee systems. These systems underpin how customer money moves through the platform, how interest is calculated and paid and how fees are collected. Their correctness, reliability and auditability are critical to customer trust, regulatory compliance, revenue assurance and operational resilience.

You will lead a small team of squad leads, each of whom leads a small team of engineers whilst remaining hands‑on in delivery. Direct line management is deliberately limited so this role can stay close to the technical detail, with a clear focus on technical leadership, delivery, engineering standards and building systems that improve long‑term engineering velocity.

You do not need experience with our exact stack, but you should be able to understand it quickly, work effectively within it and make sound technical decisions across it.

• Backend: C# / .NET Core / .NET Framework, being phased out
• Architecture: Modular monoliths, pragmatic boundaries, asynchronous processing and event‑driven patterns where appropriate
• Frameworks and libraries: Hangfire, MediatR, Entity Framework, Mass Transit and xUnit
• Azure: App Services, Functions, Service Bus, Event Hub, Cosmos DB and SQL Server
• Tooling: Git Hub, Azure Dev Ops, Terraform, Datadog and Rollbar

Own the technical direction for significant backend systems, product features and engineering initiatives. You will contribute directly to design decisions and, where needed, help teams build complex functionality.

Set a high bar for software quality, reliability, maintainability and operational excellence, particularly in areas where errors could affect customers, money movement, regulatory compliance or platform stability.

Actively review, shape and unblock engineering work. This is not a purely managerial role. You should stay close enough to the code, systems and delivery detail to identify risks, challenge weak designs and help teams make good technical decisions.

Drive a strong "get stuff done" culture. You should be able to move from ambiguity to action, make sensible trade‑offs and keep teams focused on delivering valuable software.

Provide senior technical leadership across the systems that support payments, money movement, interest and fees.

These systems support critical flows across the Moneybox platform, including interest calculations, fee collection, Direct Debits, Faster Payments and supplier integrations such as Starling, HSBC and Plaid.

You will help ensure these systems remain correct, resilient, scalable, auditable and easy to evolve as customer volumes, product complexity and regulatory expectations increase.

You will shape the long‑term technical roadmap for these areas, ensuring we can safely support new products, faster payments, improved reconciliation, clearer auditability and stronger operational controls.
