BACKEND ENGINEER

At Gradient Labs https://gradient-labs.ai/, we’re on a mission to make exceptional customer service the norm.

Founded in 2023, we’ve quickly gone from an idea to a growing team with customers you know (and probably love). Our AI agent helps businesses handle even the trickiest, high-stakes customer support queries safely and effectively, all while giving them the visibility and control they need to trust the outcomes.

We’re a small but mighty team of builders from leading companies like Monzo, Pleo, and Google. We work in a hybrid model from our London office, a short walk from Liverpool Street Station, where we collaborate and connect 2-3 days a week.

If you’re excited to tackle some of the hardest problems in AI and help shape the future of customer operations, we’d love to hear from you.

🎯 HOW YOU’LL MAKE AN IMPACT

This isn't a maintenance role or a feature factory. At Gradient Labs, you will own systems that matter — from the first architectural decision through to production, scale, and everything that breaks along the way.

You'll work on the infrastructure that makes autonomous AI agents actually reliable in the real world. That means building for failure, designing for observability, and shipping with conviction — not waiting for a perfect spec that will never arrive.

- Build the OS for AI Agents — Contribute to a safe, scalable platform that lets us iterate on autonomous agent capabilities faster than anyone else. You are building the infrastructure that makes AI actually work in production.

- Ship Resilient Systems — Design and own systems that hold up under failures, retry storms, and resource starvation — with full observability baked in. Reliability is a baseline, not an aspiration.

- Take Products from 0 → 1 → Scale — Scope something from scratch, make the early architectural calls, and stay responsible for it as it grows. We build with conviction and we see things through.

- Move Fast, Ship Often — Iterate in small incr...
