About nPlan
nPlan operates an AI platform serving major construction companies, helping them understand, manage, and reduce delay risk in some of the world's largest and most impactful construction projects. We're a small, ambitious team that moves fast, thinks hard, and cares deeply about what we build. We have Series B funding from some of the top investors across tech and construction, including Google Ventures and Suffolk, who believe in the future we are building.
The Role
The frontend team owns the suite of client-facing applications that power our platform. You will design, implement and maintain high-quality user experiences that are performant, scalable and intuitive. From complex data visualisations and workflows to AI-powered interfaces, you'll work at the intersection of product, design and engineering to deliver tools that help our users make better decisions.
What You'll Do
- Build the future of our product: design and ship new experiences across our suite of React applications, helping customers navigate complex information and make better decisions.
- Own technical decisions: identify opportunities, challenge assumptions, evaluate trade-offs and take features from concept to production. We value engineers who think critically and care about outcomes, not just implementation.
- Raise the bar: improve performance, developer experience, testing and maintainability across the frontend stack. Leave the codebase, tooling and team in a better place than you found them.
What We're Looking For
- Deep frontend engineering expertise: You understand not just how things are built, but why. You're opinionated about architecture, frameworks, tooling, and trade-offs, and can articulate why a particular approach is right for a given problem.
- Pragmatic decision maker: You know when to pursue excellence and when "good enough" is the right answer. You balance technical quality, speed, and business impact.
- Architectural mindset: You think beyond individual features and consider maintainability, scalability, performance, and developer experience. You understand the trade-offs behind frameworks and tooling decisions, and make pragmatic choices based on context.
- Curious about the ecosystem: You keep up with developments in TypeScript, React and the wider frontend ecosystem, and enjoy understanding how new tools and patterns can be applied to real-world problems.
- AI-native engineer: You actively use LLMs, Agents, and AI tools to accelerate your development workflow. nPlan is an AI-driven company and we want people who are genuinely excited about working this way - not just open to it.
- You believe that the future of UI is generative: different users should get different views based on their context, data, and history. AI Agents are no longer just about chat interfaces, they pervade the whole stack, and affect all modes of communication, so a product should be able to adapt to its users based on what it knows about them.
You might be our person if you…
- Build great user experiences: You've designed, shipped and maintained production web applications that real users depend on. You care about usability, performance and the details that turn a functional product into a great experience.
- Think beyond individual features: You're comfortable evaluating architectural trade-offs and considering maintainability, scalability and developer experience. You understand that good frontend engineering is about more than just making things work.
- Care about quality: You set a high bar for performance, accessibility, testing and reliability. You take pride in delivering polished experiences and leaving codebases in a better state than you found them.
- Work confidently across the frontend stack: You have strong experience with modern JavaScript/TypeScript, React and APIs, and are comfortable working with testing frameworks, build tooling and modern development workflows.
- Bring complex data to life: You enjoy transforming data into intuitive user experiences, whether that's through rich visualisations, thoughtful interactions or well-designed workflows.
- Thrive in autonomy: You enjoy taking ambiguous problems, clarifying requirements, and driving work to a shippable solution.
Remember to mention "crane" in your application - we're looking for people who pay attention to details.
