Our Mission 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. Foundations Vision: 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. What This Team Does 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 [... source excerpt omitted ...] API, 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. About You 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.
