About The Company

hackajob is collaborating with Monument to connect them with exceptional professionals for this role.

About Monument: 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.

About The Role

This is a build role for an engineer who wants to own their work end to end. You will design, develop, and ship digital products that directly shape how Monument's clients manage and grow their wealth, working across the full stack from polished front-end interfaces to resilient back-end services.

For the right engineer, this is a rare opportunity: meaningful ownership on a product that matters, at a pre-IPO challenger bank, working with modern tooling and an AI-first engineering culture that prioritises outcomes over process.

Qualifications

Proven full-stack engineering experience, delivering production-ready applications using React, Node.js, and AWS on web and mobile platforms.

Hands-on experience with iOS or Android native development, or React Native for mobile-first product work.

Strong working knowledge of RESTful and GraphQL APIs, serverless architectures, and CI/CD pipelines.

Comfortable in TypeScript and JavaScript, with experience in cloud-native ecosystems and modern tooling.

A track record of using data and experimentation to guide technical and product decisions.

Demonstrable experience with AI-powered engineering tools, with a considered approach to where they add genuine value.

Experience working in agile, product-led teams where speed, collaboration, and ownership are the norm.

Familiarity with UK GDPR data handling obligations and an understanding of what it means to build in a regulated environment.

Experience with event-driven systems and database technologies such as PostgreSQL or DynamoDB is advantageous.

Exposure to financial services, fintech, or other regulated environments is a plus but not a requirement.

Responsibilities

• Build, deploy, and scale high-quality, secure, and maintainable mobile applications across front-end and back-end systems, with full ownership of your code from architecture through to production monitoring.
• Collaborate closely with Product, Design, and Data teams to define problems, shape hypotheses, and ship working solutions at pace.
• Apply an AI-first approach to engineering, using tools such as Claude, GitHub Copilot, and AI agents to accelerate development, testing, and ideation without compromising quality or security.
• Instrument everything you build, tracking performance, behaviour, and conversion to inform data-driven decisions on what to build next.
• Contribute to product strategy by identifying opportunities for technical innovation and automation across Monument's digital experiences.
• Ensure operational excellence across your work, building for reliability, scalability, and compliance in a regulated financial services environment.
• Help define and evolve engineering standards, architecture patterns, and development best practices as the team scales.
• Champion simplicity in design and implementation, building systems and interfaces that are intuitive, elegant, and frictionless for clients.
