Full Stack Developer
London, Marylebone (Hybrid/Onsite)
Are you a developer who loves building products, not just features?
Do you thrive at the intersection of robust backend logic, intuitive frontend interfaces, and conversational AI?
Are you excited to join a fast-growing, seed-funded startup transforming construction procurement?
If you want to own a product from the database to the UI, we’d love to hear from you.
About Us
At Prolo, we’re reinventing procurement for the construction industry using AI. Our platform helps customers source materials effortlessly across WhatsApp, email, and phone—saving time and money with zero setup. We’re a small, ambitious team of 10 that moves fast, trusts each other, and enjoys building genuinely impactful technology.
Your Role
As a Full Stack Developer you won’t just be ticket-crunching. You will own the end-to-end experience of our platform. You’ll be responsible for architecting scalable backend services that power our AI engine while ensuring the frontend experience is world-class.
You’ll:
* Build & Own: Lead the development of new features across the entire stack (Node/Python, React, and Postgres).
* AI Integration: Design and build the interfaces and APIs that allow our users to interact seamlessly with LLMs and conversational agents.
* Product Thinking: Work directly with the founders to define the roadmap and turn customer insights into production-ready features.
* Workflow Optimization: Support our AI-led procurement engine with high-quality data integration and scalable workflows.
* User Experience: Ensure our chat and workflow interfaces are intuitive, fast, and reliable for real-world users in the field.
* Scale: Help shape our engineering culture and technical architecture from the ground up as we grow.
What We’re Looking For
* The Full Stack: Strong experience with modern frontend frameworks (React) and backend environments (Node.js, Python, or similar).
* Startup DNA: You are comfortable in a fast-moving, seed-stage environment where you often have to figure things out from scratch.
* Product Mindset: You care about why we are building something, not just how. You are user-focused and commercially aware.
* AI Curiosity: Deep interest in LLMs and conversational products; experience with AI APIs is a significant plus.
* Ownership: You take pride in shipping high-quality, tested code and seeing it deliver value to customers.
1. What’s in It for You?
* Equity: Become a true stakeholder in Prolo’s success.
* Impact: Real ownership over a core product that construction firms rely on daily.
* Tech: Work on cutting-edge conversational AI technology.
* Location: Join us in our Marylebone office with a flexible hybrid rhythm.
* Culture: A high-trust environment that values pace, transparency, and impact.
