Productgenius The Backend Engineer at Productgenius will build and maintain backend systems for a real-time learning AI, including APIs and data pipelines. The role requires hands-on development, production ownership, and championing engineering practices like AI-assisted coding and CI/CD.

Responsibilities

You'll build and maintain the backend systems at the core of a real-time learning AI: the APIs and data pipelines that connect live user and merchant behavior to systems that learn from it. You'll work alongside exceptional AI researchers and engineers, with real autonomy to shape how that architecture evolves.
This is a hands-on, AI-native engineering role. You'll need to subscribe to agentic-led development. You'll use agentic coding tools daily, including managing multiple parallel coding sessions, to move quickly through a complex and fast-changing codebase. You'll be trusted with context and the freedom to decide how to use it, not handed a task list.
Real-time learning engine. Contribute directly to the systems at the core of the business.
APIs and data pipelines. Build and maintain the connections between live user behavior and our self-learning systems.
Engineering practices. Champion practices that safely accelerate the team: AI-assisted coding, streamlined CI/CD, and stronger QA.
Production ownership. Own what you ship. Dig into logs and traces, find root causes, and improve testing to prevent issues before they recur.

Required

5+ years of experience building and maintaining production backend systems.
Hands-on daily experience with agentic AI coding tools, comfortable managing multiple parallel sessions.

Comfortable picking up any language; we typically use Python, SQL, TypeScript, and React.
Able to jump into a complex, unfamiliar codebase and rapidly get productive in it.
Collaborative at the level of shared context and problem framing; self-sufficient at the level of code.
Strong math or analytical background. Bachelor's degree in Computer Science, Engineering, Mathematics, or a related field, or equivalent experience.
You're the person who spins up a newly released tool or framework just to see what's possible.
You've run an LLM on your local machine for fun.
Exposure to containerization and orchestration tooling (Docker, Kubernetes, Terraform, GCP).
Experience with ClickHouse queries and optimization.
Comfortable in a fast-moving startup environment where priorities and scope can shift quickly.
