Gradient Labs is an AI-driven company focusing on automating complex customer support interactions through its powerful AI agent named Otto. This agent is designed to handle intricate customer inquiries by learning from written procedures, offering seamless integration into existing support platforms. Gradient Labs aims to enhance customer service efficiency while maintaining high satisfaction rates, enabling businesses to automate significant portions of their customer support processes without the need for coding or complex setups.

📋 Description

• 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 increments. Multiple deploys a day. Comfort with ambiguity is not optional — it is the job. The mission moves faster than the roadmap.

🎯 Requirements

• Substantial tenure building production software at a fast-growing company — fintech, AI, consumer tech, or any environment where pace and stakes were both high • Proven experience owning complex, high-stakes systems end to end — not handing off at merge, but staying accountable through observability, iteration, and scale • Deep fluency in Go (Golang) and comfort operating across a modern backend stack (PostgreSQL, Temporal, GCP, Kubernetes) • A product instinct that goes beyond technical elegance — you think from the customer backwards and bring that into every architectural decision • Senior, Staff, Principal or Distinguished level in practice — someone who has operated with real scope and real accountability • Genuine excitement for autonomous AI as a platform shift, not a trend — you want to build the infrastructure that makes agents genuinely reliable • Strong opinions, loosely held — conviction without ego, and always willing to be wrong in pursuit of the right answer.

🏖️ Benefits

• Flexible work arrangements • Professional development opportunities
