Job Summary
As a Frontend Software Engineer, you will be part of a highly collaborative, agile, and empowered product delivery team, dedicated to building the interfaces our brands and shoppers use to experience AI-driven personalisation, recommendations, and agentic decisioning in real time.
You'll own the React/TypeScript front end of our platform end-to-end, from performant, low-latency on-site experiences to the internal tools our teams use to configure and monitor AI agents, working closely with the backend engineers (Go, C#/.NET) and AI/ML teams who power them.
This is a great opportunity to work in an environment that embraces cutting-edge technologies, with a strong focus on React, TypeScript, and modern front-end architecture for AI-powered products. Exposure to, or an appetite to pick up, Go and/or C#/.NET is a genuine plus, since you'll frequently be working across the API boundary with those services.
We're looking for someone who is passionate about writing high-quality front-end software and thrives in a collaborative team environment.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Key Responsibilities
- Designing and building modern, performant front-end applications using React and TypeScript, including AI-powered and agentic user experiences (real-time personalisation, recommendations, conversational/agent interfaces)
- Translating intent scoring, decisioning, and analytics outputs from our AI/agentic services into clear, responsive, and delightful UI
- Collaborating closely with backend engineers on Go and C#/.NET services to help shape clean, well-documented APIs that serve the front end well
- Building and maintaining reusable component libraries and design-system foundations across our product suite
- Optimising for performance, accessibility, and reliability, including in edge/onsite personalisation contexts where flicker and load time are critical
- Writing clean, maintainable, and efficient code following industry best practices (e.g., SOLID principles, component-driven design)
- Collaborating within an agile, Scrum-driven team, participating in sprints and planning sessions
- Contributing to automated testing, CI/CD pipelines, and monitoring production front-end systems
- Engaging in peer code reviews and mentoring junior engineers to support knowledge-sharing and team growth
Essential Skills & Experience
- Strong, hands-on experience with React and TypeScript in production applications
- Solid grounding in modern JavaScript/TypeScript, component architecture, and state management
- Experience building UI for data-rich or AI-powered products (analytics dashboards, recommendation surfaces, real-time personalisation, or similar)
- Comfortable consuming and helping shape RESTful (or similar) APIs from front-end code
- Familiar with git or other distributed source control systems
- A problem-solver with a proactive approach to diagnosing and resolving issues
- Passionate about writing clean, maintainable, and scalable front-end code
- Experience building and maintaining automated test suites with Cypress/Jest, or similar
- Experience with project management tools such as JIRA
Nice to have
- Experience with Go and/or C#/.NET enough to read, debug, or contribute to the services your UI talks to is a strong plus
- Familiarity with cloud computing platforms (AWS, Azure)
- Exposure to AI/ML-powered products: LLM-driven features, agentic systems, recommendation engines, or A/B testing platforms
- Familiarity with operating in an ISO 27001-certified environment
- Experience with Docker and containerised environments
- Knowledge of CI/CD pipelines and DevOps practices
- Familiarity with updating and maintaining dependencies to proactively address security risks
- Experience with mentoring, training, or knowledge sharing within a team
