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.\nFoundations\nVision:\nBuild 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.\nWhat This Team Does\nBuild and operate the core shared services that power our research, training, and production environments. These systems form the foundational platform that multiple teams depend on for model development, deployment, and evaluation, unifying data, compute, and workflow management across the stack while enabling rapid experimentation and reliable production systems.\nBuild and operate shared services that multiple teams rely on across research and production workflows.\n\nDefine and uphold reliability targets through SLIs, SLOs, and healthy on-call practices.\n\nMaintain strong operational readiness with runbooks, incident playbooks, and capacity planning.\n\nEnsure correctness and performance under load, addressing consistency, tail latency, and failure modes.\n\nDevelop APIs, SDKs, and internal platforms that enable high-velocity experimentation and iteration.\n\nReduce operational burden through better tooling, standardization, and platform patterns that scale across teams.\n\nWhat You'll Work With\nContainer Abstractions: Containers-as-a-Service, Kubernetes abstraction layers, container orchestration, reproducible environments, multi-tenant isolation.\n\nDistributed Systems Architecture: Sharding, replication, coordination services, high-concurrency systems, concurrency control.\n\nService Development Stack: gRPC, Protobuf, Go, Rust, C++.\n\nReliability & Performance: Idempotency, retries, backpressure, SLI/SLO design, tail latency optimization, service reliability engineering.\n\nAbout You\nStrong software engineering background with experience shipping production-grade systems.\n\nExperience designing APIs, services, or developer platforms that handle large-scale data or compute.\n\nComfortable navigating complex codebases, debugging hard problems, and optimizing for reliability and speed.\n\nThrive in a high-agency, fast-paced startup environment; bias toward action and impact.\n\nExcited about zero to one challenges, building new systems rather than maintaining legacy ones.\n\nCollaborative, clear communicator, and comfortable working across research and infra boundaries.\n\nMotivated by creating the software backbone for the world’s most capable open-weight AI systems.\n\nWhat We Offer:\nWe believe that to make intelligence open and accessible to all, you need to start at the foundation. Joining Reflection means building from the ground up as part of a talent-dense team. You will help define our future as a company, and help define the future of open foundational models.\nWe 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.\nTop-tier compensation: Salary and equity structured to recognize and retain our talent globally.\n\nStock options: Everyone who joins and contributes to Reflection's success gets to share in the upside through stock options.\n\nHealth & wellness: Comprehensive medical, dental, vision, and life, with an annual wellness allowance.\n\nMeals: Lunch and dinner are provided in the office daily.\n\nLife & family: 22 weeks paid parental leave for all new birthing and non-birthing parents, including adoptive and surrogate journeys.\n\nVacation days: Unlimited paid time off in the U.S. and 30 days in the U.K.\n\nSponsorship support: We sponsor visas to help exceptional talent join our team and support long-term immigration pathways where applicable.\n\nTeam building: We have regular off-sites, happy hours, and team celebrations.\n\nExport Control Notice: This position may require access to technology or source code subject to the U.S. Export Administration Regulations.
