Overview

We're building the next generation of AI-powered development tools. Our CLI coding agent is designed to be a true collaborator for professional developers – one that understands complex codebases, learns from feedback, and delivers production‑ready code.

As a Product Engineer at OpenBlock Labs, you'll shape how developers interact with AI assistants. You'll design and build the systems that make our agent intuitive, reliable, and indispensable to engineering teams worldwide. Your work will directly impact how millions of developers write, review, and ship code.

Responsibilities

Design and implement the core CLI experience that defines how developers interact with our agent.

Build sophisticated context‑management systems that enable the agent to navigate and understand large codebases.

Develop interactive workflows for testing, debugging, and iterative refinement of generated code.

Create feedback systems that capture developer intent and improve agent performance over time.

Integrate seamlessly with existing developer tools and workflows.

Establish metrics and monitoring to measure real‑world impact on developer productivity.

About You

Have deep experience building developer tools and understand what makes them successful.

Are passionate about developer experience and have strong intuitions about interface design.

Can balance rapid prototyping with building robust, scalable systems.

Think systematically about performance, reliability, and user workflows.

Have experience shipping products used by thousands of developers.

Are excited about the potential of AI to transform software development.

Thrive in fast‑paced environments where you can have significant impact.

Strong experience building command‑line interfaces and developer tools.

Deep understanding of asynchronous programming, state management, and real‑time systems.

Familiarity with code analysis tools, ASTs, and language server protocols.

Experience with performance optimization and building for scale.

Track record of shipping high‑quality software in production environments.

What We Offer

Opportunity to work on cutting‑edge AI technology with real‑world impact.

Collaborative environment with a world‑class team of engineers and researchers.

Flexible work arrangements with our San Francisco office as a hub for collaboration.
