Member of Technical Staff - Applications

Reflection is a research lab making intelligence open and accessible for everyone to use, customize, and build on. We build open models that let anyone control their intelligence and help shape the future of AI. Our mission: make intelligence open and accessible to all.

Build and operate a company-wide foundations platform that accelerates every team by providing reliable, scalable developer infrastructure, SRE capabilities, and high-throughput data ingestion tooling enabling Reflection to move faster as we scale.

Build the internal and customer-facing product surfaces that turn platform capabilities into usable workflows. This role sits at the intersection of engineering and product translating ambiguous requirements into clean, operable systems and taking ideas from early prototype to hardened production components.

• Build internal product surfaces such as dashboards, admin tools, and self-serve workflows.

• Own end-to-end delivery across UI, APIs, authentication, RBAC, and audit trails.

• Integrate with customer environments and adjacent systems to ensure seamless workflows.

• Productionize prototypes into reliable, maintainable, and operable platform components.

• Translate fuzzy product requirements into clear system designs and usable interfaces.

• Feed delivery learnings back into platform patterns and defaults so the next system ships faster.

• Full-Stack & API Development: React, TypeScript, REST, gRPC, FastAPI, Go services, API design.

• Auth & Governance: OIDC authentication, RBAC, audit logging.

• Workflows & Integrations: Event-driven systems, workflow orchestration, feature flags, customer integrations.

• Monitoring & Developer Tooling: Dashboards, observability tooling, experiment tracking systems, metrics and log visualization.

• Strong full-stack engineering background with experience shipping production-grade applications end-to-end.

• Comfortable owning the full delivery surface — UI through API through auth — without needing to hand off between layers.

• Experience integrating with external systems or customer environments and making those integrations reliable and maintainable.

• Thrive in a high-agency, fast-paced environment; bias toward action and impact.

• Excited about zero to one challenges — turning prototypes into real systems rather than polishing existing ones.

• Collaborative, clear communicator, comfortable working across research, platform, and product boundaries.

• Motivated by building the tooling and workflows that let the world's most capable open-weight AI systems get built faster.
