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.
ABOUT THE ROLE
Reflection's Applications team builds the product surfaces that turn raw platform capabilities into usable workflows — the internal dashboards, admin tools, and self-serve experiences our teams run on, and the customer-facing surfaces that connect Reflection to the outside world. This work sits at the intersection of engineering and product: translating ambiguous requirements into clean, operable systems and taking ideas from prototype to hardened production.
As Applications Lead, you'll provide front-line leadership of the team that builds these surfaces. You'll build, mentor, and grow a team of full-stack engineers, guide the technical and architectural decisions that shape what we ship, and work closely with research, platform, and product to decide what gets built and how. You'll stay close enough to the stack — UI through API through auth — to make targeted contributions as an individual contributor and to maintain a deep understanding of the team's technical work.
WHAT YOU'LL DO
-
Build, mentor, and grow a high-performing team of full-stack engineers. Coach and support your reports in understanding, and pursuing, their professional growth.
-
Provide front-line leadership of engineering efforts to build internal and customer-facing product surfaces dashboards, admin tools, and self-serve workflows.
-
Stay hands-on: become familiar with the team's technical stack enough to make targeted contributions as an individual contributor.
-
Manage day-to-day execution: prioritize the team's work and manage projects in a highly dynamic, fast-paced environment.
-
Guide technical and architectural decisions, emphasizing scalability, robustness, and user experience across React/TypeScript front ends, REST/gRPC APIs, Go/FastAPI services, and the auth, RBAC, and audit underneath.
-
Work closely with research, platform, and product to translate needs into clear system designs and usable interfaces, and to make integrations with customer environments reliable and maintainable.
-
Raise the bar for technical judgment, prioritization, communication, and execution in a fast-moving environment.
