We welcome collaborators from all backgrounds and experiences who share our curiosity, creativity, and care for craft.

We believe great work comes from diverse perspectives and shared purpose. If you’re passionate about learning, experimenting, and making work that matters, we’d love to hear from you.

We’re seeking a hands-on Technical Lead to architect, guide, and deliver the technical foundation for a new web platform centered around a retrieval-augmented generation (RAG) search experience. You will partner closely with a Technical Director and Technical Producer while leading a small development team (Frontend + Backend) to build a secure, scalable, and high-performing AI-powered application.

You will define the technical vision, design the system architecture, and establish the infrastructure that enables the team to move quickly and confidently. This includes architecting the Vertex AI–powered search implementation, shaping the data ingestion and vectorization pipelines, and building the Dev Ops frameworks (CI/CD, Cloud Build, IAM strategy, staging/production environments) that support smooth delivery.

This is both a strategic and hands-on role. You’ll be the technical force multiplier—clearing blockers, ensuring quality, and guiding the team toward a robust, production-ready solution.
