Frontend Developer React

Looking to make a real-world impact through your code? I'm hiring for a Mid-Level Frontend Developer to join a high-growth, AI-driven startup that's transforming how UK cities make transport decisions. You'll play a hands-on role in shaping their main product, an intelligent assistant that brings data-driven insights to the desks of city planners and transport authorities-no data science degree required.

This is a mission-led team building tech that supports cleaner, smarter, and more sustainable cities, backed by top researchers and live pilots in major UK metros.

• Up to £50,000 depending on experience

• Fully remote-first (UK-based, with flexible collaboration)

• Build products with visible public impact

• Flat structure, strong mentorship, real ownership

• Blend your frontend skills with an exciting mix of AI, mapping, and urban innovation

• Help craft intuitive, highly usable UIs for their main product (their flagship AI-powered analytics tool).

• Build interactive components and dashboards for non-technical users working in transport and sustainability

• Collaborate with design and backend teams to translate complex data outputs into clear visuals

• Integrate mapping tools (e.g. OpenStreetMap) and data visualisation features

• Work in a fast-moving environment, where shipping clean, scalable code matters

• Solid experience in modern JavaScript, especially React

• Proficiency with HTML/CSS, component libraries, and API-driven apps

• Strong attention to usability and detail-you build things people actually want to use

• Comfortable working in a cross-functional startup team

• Bonus if you've worked with: Mapbox/OpenStreetMap, data visualisation libraries, or TypeScript

TransHumanity is solving a critical problem: how to make transport data actionable for cities. Instead of dashboards buried in spreadsheets, our product brings clear answers and smart recommendations directly to the people making transport decisions.

We're already live in UK city pilots, shortlisted for national awards, and supported by leading experts from Loughborough University and beyond.
