Our Mission

Reflection’s mission is to build open superintelligence and make it accessible to all.

We’re developing open weight models for individuals, agents, enterprises, and even nation states. Our team of AI researchers and company builders come from DeepMind, OpenAI, Google Brain, Meta, Character.AI, Anthropic and beyond.

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 next system ships faster.

What You'll Work With

• 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.

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.

• 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.

What We Offer:

We believe that to build superintelligence that is truly open, you need to start at the foundation. Joining Reflection means building from the ground up as part of a small talent-dense team. You will help define our future as a company, and help define the frontier of open foundational models.

We want you to do the most impactful work of your career with the confidence that you and the people you care about most are supported.

• Top-tier compensation: Salary and equity structured to recognize and retain the best talent globally.

• Health & wellness: Comprehensive medical, dental, vision, life, and disability insurance.

• Life & family: Fully paid parental leave for all new parents, including adoptive and surrogate journeys. Financial support for family planning.

• Benefits & balance: paid time off when you need it, relocation support, and more perks that optimize your time.

• Opportunities to connect with teammates: lunch and dinner are provided daily. We have regular off-sites and team celebrations.
