Department: Engineering

Team Overview

The Financial Services team enables RVU to help customers make the best decisions around financial products, by helping them identify the right products from our partners across our three main brands: Uswitch, Confused.com and money.co.uk. Our engineering team builds web apps, back‑office systems and tooling used to deliver financial product pages across RVU’s websites, integrate with our partners, track sales, optimise marketing, and manage business reporting. We are currently expanding our offering to small and medium businesses by driving deeper integration with partner APIs, improving the customer experience on our platform, streamlining journeys, and ensuring the business has all the data it needs. Our technology stack is centred around TypeScript, React and Node/Bun, running on Kubernetes in AWS.

What you’ll be doing

As a Lead or Staff Software Engineer, you will work closely with business leads, commercial managers, ops executives, product managers, data analysts, designers, and fellow engineers to solve business problems with software. This role is more technical, with less management responsibility. You will contribute across the full stack—from infrastructure, databases, pipelines, and servers to web UIs, CDNs, and monitoring. Activities include building responsive accessible React components aligned with our design system, working with APIs, using real‑time metrics and alerting, interacting with databases, and keeping applications secure. You will identify opportunities for process improvements, conduct code reviews, and ensure solutions are properly tested with a focus on best practices and quality assurance. You will also work closely with AI, incorporating it into workflows and projects, finding new ways to leverage AI for business value, and evangelising AI adoption across the business. Most importantly, you will support and improve the engineering team’s delivery and technical expertise in a continuous learning environment, helping shape the future of Financial Services within RVU and guiding the team along the way.

What we’re looking for

We want a technical expert who will be a multiplier for the team: bringing your own experience and knowledge to enrich the skills and foster growth. You should be comfortable building cloud‑native scalable applications as well as styling responsive React components. You should have experience ranging from building MVPs to large‑scale production systems, striking the right balance between rigor and urgency, making pragmatic decisions that benefit the business, and assessing friction points to deliver maximum return. Knowledge of AI-enabled applications and workflows is essential, including familiarity with platforms and frameworks such as N8N, Mastra, vector stores, RAG, fine‑tuning and evaluation. A growth mindset, keen to learn and explore, and the ability to debug large and complex systems are required. You should keep abreast of industry developments, assess and introduce new libraries, technologies, tools, and approaches—especially regarding AI advancements.

Key Skills

• Strong TypeScript skills, convinced of the benefits of statically typed languages
• Deep knowledge of the Node ecosystem (node, npm, yarn), including bundling and dependency management. Familiarity with Bun is also desirable
• Proficient with AI tooling, including delivering code using CLI or editor‑based LLM agents, and using MCP servers
• Solid understanding of the React paradigm, including one‑way data binding, declarative programming, rules of hooks, and anti‑patterns
• Practical experience of software engineering principles and managing complexity (e.g. separation of concerns, design patterns, domain‑driven design) and aspiring to write elegant clean code
• Familiarity with container‑based cloud‑native applications and architectural patterns such as REST APIs, message passing, horizontal and vertical scaling, and load balancing
• Knowledge of web security concerns (e.g. SQL injection, XSS, CORS, cookies, authentication/authorisation techniques)

Experience with the following is a plus:

• Kubernetes, Prometheus, Argo workflows, GitHub Actions, Elasticsearch/Opensearch, PostgreSQL, BigQuery, DBT data pipelines, Fastly, Storybook, component libraries and design systems, Builder.io, Bun

You don’t need to tick off everything on this list – don’t let that hold you back from applying. We want to ensure you’re learning plenty during your time with us.
