Expert proficiency in TypeScript and React, with a portfolio of production web applications you've owned end-to-end. * UX and design sensibility. Strong understanding of UX principles and web design fundamentals. You care about interfaces that feel considered, not merely functional. * Real-time and reactive patterns. Experience with real-time and bi-directional communication protocols (WebSockets, SSE) and managing complex asynchronous state. * Full-stack capability. Comfortable going down the stack when features call for it, and confident contributing to API and system design conversations. * Cloud deployment. You've built and deployed services on at least one major cloud provider (AWS, GCP, or Azure). * Product mindset. You care about the people using what you build, and you take ownership for what your team puts in front of them, not just the part you wrote. * Shipping at pace. Evidence that you can move complex, customer-facing products into production quickly, making pragmatic decisions without letting perfection become a blocker. * AI-native engineering. You've shipped production code with frontier AI tools (Cursor, Claude Code, or similar) and push further into agentic workflows rather than push back on them. Nice to Have (or We Can Teach) * Backend and event-driven experience. Comfort with backend development and event-driven architecture. Our stack includes Python, FastAPI, Postgres, Kafka, and MQTT. * IoT or edge architectures. Experience working with IoT, edge computing, or hardware-adjacent systems. * B2B or enterprise product experience. Background building for business or enterprise customers, where reliability, integrations, and data pipelines matter as much as the interface. * Retail or personalisation. Familiarity with retail technology, commerce platforms, inventory systems, loyalty programs, or customer personalisation. * Startup experience. Background working at an early-stage startup. ## Description This role reports to our Head of B2B Product, James. Working with him and our product, design, mobile, and machine-learning teams, you'll design and build the web experiences that redefine how brands and retailers serve their shoppers. You'll be a full-stack engineer with a frontend centre of gravity, going as far down the stack as each feature needs. You'll turn ambitious and sometimes ambiguous product ideas into software that retailers and brand partners rely on to create, launch, and measure their in-store activity. You'll be shaping the interfaces that our B2B customers use every day, making the calls on how complex, intelligent capabilities get expressed through interfaces that non-technical users can pick up and trust. We're agentic-first. Every engineer has access to frontier AI tooling and our own coding harness, and we expect you to use them to move faster, attempt more ambitious work, and stay fully accountable for what you ship. What You'll Own * Full-stack delivery end-to-end. Own substantial features from product conversation through design, implementation, and iteration in production. Most of the weight sits in the frontend, but you go as far down the stack as the feature needs. * Reactive web interfaces. Design and build the responsive, real-time interfaces that let brands and retailers manage and analyse the in-store experience our product delivers. * Translating complexity into simplicity. Turn user and business needs into interfaces that make complex, intelligent capabilities feel elegantly simple to non-technical audiences. * Product partnership. Work in a cross-functional team alongside our Head of B2B Product, prototyping and validating ideas quickly, then shipping the ones that hold up. * API and system contribution. Contribute to API design, system design, and documentation as part of end-to-end delivery, not as an afterthought. * Production quality. Own testing, observability, and post-release investigation for the interfaces you ship. ## Related Videos - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Intro to FastAPI](https://www.wearedevelopers.com/videos/462-intro-to-fastapi) - [Build and Deploy a Fullstack App with Open Source Tooling](https://www.wearedevelopers.com/videos/775-build-and-deploy-a-fullstack-app-with-open-source-tooling) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) ## Related Articles - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
