Member of Technical Staff - Applications

Reflection is a research lab building open AI models. This role focuses on building internal and customer-facing product surfaces that turn platform capabilities into usable workflows, sitting at the intersection of engineering and product.

• 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.

• 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.

• Top-tier compensation: Salary and equity structured to recognize and retain our talent globally.
• Stock options: Everyone who joins and contributes to Reflection's success gets to share in the upside through stock options.
• Health & wellness: Comprehensive medical, dental, vision, and life, with an annual wellness allowance.
• Meals: Lunch and dinner are provided in the office daily.
• Life & family: 22 weeks paid parental leave for all new birthing and non-birthing parents, including adoptive and surrogate journeys.
• Vacation days: Unlimited paid time off in the U.S. and 30 days in the U.K.
• Sponsorship support: We sponsor visas to help exceptional talent join our team and support long-term immigration pathways where applicable.
• Team building: We have regular off-sites, happy hours, and team celebrations.
