Member of Technical Staff

Shape the Future of AI

At Labelbox, we're building critical infrastructure for breakthrough AI models at leading research labs and enterprises. Since 2018, we've pioneered data-centric approaches fundamental to AI development.

The Role

We're hiring a Member of Technical Staff to design, develop, and produce Frontier Data Products. You'll build sandboxed, reproducible environments AI agents rely on during training and evaluation.

What You'll Do

• Design, build, and maintain sandboxed RL environments for agentic AI training
• Develop reproducible, containerized execution environments
• Integrate with and extend open-source agentic tooling and custom CLI/API harnesses
• Build instrumentation and observability layers
• Collaborate with data operations to design task curricula and evaluation protocols
• Own environment deployment and reliability
• Rapidly prototype new environment types

What We're Looking For

• 2+ years of professional software engineering experience with strong fundamentals in Python and at least one systems-level language
• Demonstrated experience with containerization and sandboxing
• Familiarity with RL concepts
• Experience building or maintaining developer tooling, CLI tools, or infrastructure automation
• Comfort working with browser automation frameworks or terminal interaction tooling
• Strong debugging instincts
• Ability to read and implement from academic papers and open-source benchmark repositories

Why This Role Matters

• Reinforcement learning has become the state-of-the-art approach for training agentic AI, and environment quality is one of its biggest bottlenecks
• You'll work across a portfolio of projects spanning different AI labs and model capabilities
• Alignerr is a small, high-impact team inside Labelbox with startup-level ownership and growth-stage resources

Life at Labelbox

• Fast-paced and high-intensity environment
• Career advancement opportunities directly tied to your impact
• Be part of building the foundation for humanity's most transformative technology
