More:

We are an energetic and driven 15-person start-up making an impact in the transport infrastructure space. We turn complex mobility data into clear, evidence-based decisions for the people running the UKs transport networks by building data infrastructure that processes data from multiple sources, including road cameras and sensors, and using AI to make smart recommendations. Our platform helps cities and transport authorities improve bus networks, plan roadworks, monitor highways, and model what-if scenarios. We work mainly remotely, with in-person time at least once a month, and our team is based around London, Cambridge, and Bristol. We offer a company pension, an employee stock ownership plan, private medical insurance, and a salary of £75,000 to £85,000 per year.

• We are looking for a software engineer who can design, build, and ship across the stack, with a product-engineering bias.
• We require 4+ years of experience building software that real users depend on.
• We value strong product instincts and experience shaping what gets built, not just how it gets built.
• We look for understanding of agentic AI coding practices and the ability to use tools like Cursor and Claude effectively in a collaborative team.
• We want someone who is ownership-driven and mission-focused.
• We prefer candidates who enjoy working closely with end users and shaping 0*1 products.
• Bonus points if you have experience with data platforms, geospatial data, or transport/mobility.
• Bonus points if you have prior work on LLM tools, agents, or retrieval systems.
• Bonus points if you are familiar with our stack: React, TypeScript, Python, FastAPI, Dagster, dbt, Snowflake.
