The role
We're looking for a Senior Full Stack Engineer with a front-end focus who has experience working with commercial. You'll turn a marketing campaign, a pricing test or a new product launch into a fast, reliable experience, then measure whether it worked.
Your main focus will be zoe.com and our acquisition and conversion journeys, including landing pages, checkout, sign-up and product launches across our app subscriptions and physical products. You'll spend most of your time in TypeScript, React and Next.js, and you'll work in our backend services (Kotlin or Python) whenever a feature needs it.
This is a senior individual contributor role. We're looking for someone who works autonomously, makes sound decisions independently and takes full ownership of their work.
💻 Our Stack
Frontend: TypeScript, React, Next.js, React, GraphQL
Backend: Kotlin / Spring Boot, Python / FastAPI and Django
Tools: DatoCMS / headless CMS, Optimizely / AB testing tools, Grafana, Sentry, Firebase Auth
CI/CD: ArgoCD, GitHub Actions
Data: web data layer, dbt, BigQuery
Infrastructure: GCP, Kubernetes, Terraform, Vercel
🎯 What you'll be doing
Owning growth initiatives end to end: from shaping the idea with commercial partners, through technical delivery, to measuring the result.
Partnering with commercial teams: working day to day with marketing, CRM and product to deliver campaigns, launches and acquisition journeys, often to tight, business-critical deadlines.
Running experiments: designing, launching and analysing A/B tests with our analysts, and using the results to decide what to build next.
Building a fast, high-converting zoe.com: owning web performance, accessibility and conversion across key journeys such as landing pages, sign-up and checkout.
Adapting to changing priorities: making pragmatic trade-offs when plans change, and helping the team decide what to build, what to defer and what to drop.
Working across the stack: shaping APIs and making backend changes where growth features need them, in Kotlin or Python.
Contributing to the design system: helping grow our shared component library so the team can ship consistent experiences quickly.
Shipping continuously: releasing to production daily, often more than once, with the testing and monitoring in place to do so safely.
🧠 We think you'd be great if you...
Have 5+ years of professional software development experience, with a strong focus on front-end.
Have strong experience with TypeScript, React and Next.js, and know how to build fast, accessible and well-tested web experiences.
Have worked closely with commercial functions such as marketing, growth, sales or CRM, and enjoy turning business goals into product outcomes.
Have hands-on experience with experimentation and analytics, such as A/B testing, conversion optimisation or funnel analysis.
Work autonomously: you take ownership of ambiguous problems, make decisions with limited guidance and keep stakeholders informed.
Have working knowledge of a backend language (such as Python, Kotlin or Java) and are comfortable making backend changes.
Have worked in a startup or scale-up environment and are comfortable with a fast pace and shifting priorities.
