About the role

As a Frontier Engineer, you'll help build AI that moves the world forward. Working at the frontier of technology, you'll join a lean, high-impact pod where human ingenuity and AI come together to solve real-world challenges for some of the world's leading organizations. You'll partner directly with clients to design, deploy and continuously improve AI-native systems, with the freedom to experiment with emerging technologies and turn bold ideas into real impact.

In this role, you will

• Build and orchestrate multi-agent AI systems, integrating agent outputs into production environments that solve real business problems.

• Design intent-driven prompts and workflows for AI coding agents, applying human judgment to validate quality, safety and accuracy.

• Create scalable RAG architectures, vector stores and knowledge systems that enable trustworthy and context-aware AI experiences.

• Deploy, monitor and optimize LLMs and AI agents in production, implementing responsible AI guardrails and observability practices.

• Build AI-embedded applications and workflows using enterprise AI platforms, automation tools and modern engineering practices.
