Reflection is seeking a Research Program Manager to lead foundational efforts in model evaluation and safety. This role demands a proactive individual with 7+ years in technical program management or ML engineering, capable of establishing evaluative frameworks and ensuring robust operational processes. You will collaborate with cross-functional teams, driving model safety efforts while fostering a culture of continuous improvement. Join a fast-paced environment to shape the future of AI at Reflection, backed by top-tier compensation and comprehensive benefits.
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. About the Role Research Program Managers at Reflection are high-leverage leaders and operators who embed directly with research and infrastructure teams to accelerate the pace of frontier model development. They are not project trackers. They are force multipliers who bring clarity to ambiguity, drive decisions when the path forward is unclear, and ensure that the work happening across multiple teams connects into a coherent whole. This is a foundational role. Reflection is building model evals and safety from the ground up, and this RPM will be at the center of that effort. You won't be stepping into an established function with existing processes and tooling. You will be the person who figures out what this function needs to look like, stands it up, and makes it real. That means defining the evaluation frameworks, building the operational infrastructure for model safety, establishing the processes that connect evals to the model development lifecycle, and laying the groundwork for how Reflection interfaces with the broader safety ecosystem. This is 0-to-1 work in its purest form. You bring a first-responder mentality. When things go sideways, you don't wait to be asked. You jump in, assess the situation, cut through noise, align the people who need to be aligned, and drive resolution. What You'll Do Build the foundational infrastructure for model evals and safety at Reflection. Define the evaluation frameworks, tooling requirements, and operational processes that will underpin how we assess model capabilities, risks, and readiness for release. Stand up model safety operations as a function, including establishing the workflows, review cadences, and decision frameworks that connect safety evaluation to the model development and release lifecycle. Partner with research and engineering leads across pre-training, mid-training, and post-training to embed safety and evaluation checkpoints into the development process in a way that is rigorous without being a bottleneck. Drive the scoping and prioritization of eval science and eval infrastructure investments, working with technical leads to determine what to build in-house, what to adopt, and where to invest research effort. Establish Reflection's engagement with the external safety ecosystem, including third party assessments, academic partnerships, and industry safety frameworks. Represent the company's safety posture to external stakeholders with credibility and clarity. Create visibility and reporting structures that give leadership a clear, honest picture of model safety status, evaluation coverage, and open risks, so they can make informed decisions at the pace the business requires. Champion a culture of blameless post mortems and continuous learning, turning every safety relevant finding into a concrete improvement to our systems and processes. About You 7+ years of experience in technical program management, research operations, or ML engineering, with demonstrated experience standing up new functions, teams, or programs from scratch. Familiar with the landscape of model evaluation and AI safety, including evaluation methodologies, red teaming, alignment research, and the evolving regulatory and industry safety ecosystem. You don't need to be a safety researcher, but you need to understand the space well enough to make sound judgments about what matters and what to prioritize. Deep enough technically to engage with researchers and engineers on topics like model behavior, evaluation design, data pipelines, and safety critical system architecture. You follow the technical thread and you know when something doesn't add up. Proven ability to build structures where none exists. You've taken ambiguous mandates and turned them into functioning programs with clear ownership, measurable outcomes, and durable processes. Strong stakeholder management skills spanning deeply technical ICs, research leadership, and external partners. You build trust through competence and follow through. Excited to build from zero to one. We are a small, fast moving team and this role will help define how model safety and evaluation works at Reflection. Motivated by enabling researchers and engineers to build the world's most capable open weight AI systems, responsibly. 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.

Provide front-line leadership of engineering efforts to keep the compute fleet reliable and highly available - multi-cloud scheduling, cluster management, and the path to next-generation GPUs and increasingly larger cluster sizes. 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 reliability - automatic remediation, topology-aware scheduling, capacity planning, rapid hardware debugging, and cluster-wide monitoring and performance benchmarking. Work closely with our training teams to co-design fault tolerance, node health checks, and remediation, and manage the vendor relationships and important deals the compute fleet depends on. Prepare the fleet for what's next: next-generation GPUs and larger clusters, and - longer term - multi-cloud storage, petabyte-scale data replication, and GPU-to-GPU network performance. Raise the bar for technical judgment, prioritization, communication, and execution in a fast-moving environment. WHAT WE'RE LOOKING FOR Experience building, mentoring, and growing systems or infrastructure teams while staying technically hands-on. (Comfortable growing into leading a team of 10 quickly if you haven't managed at that scale before.) Deep systems-level engineering experience with a focus on cluster-wide behavior and maintenance. Strong coding ability and the credibility to earn the technical trust of a strong team. Depth in at least one of orchestration, storage, or GPU hardware - with the ability to learn the rest. Deep GPU knowledge beyond standard Kubernetes (e.g., NCCL) is a plus, not a prerequisite. Alignment with a Kubernetes-first architecture. Cloud storage expertise - managing high-performance data products (like VAST) across multiple data centers and handling datasets and checkpointing at scale - is a plus. Experience managing vendors, including negotiating and operating important deals. Ability to guide strategy and drive execution across a multi-cloud, large-fleet environment, and to partner effectively with research and training teams. What We Offer: We 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. 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 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. Export Control Notice: This position may require access to technology or source code subject to the U.S. Export Administration Regulations. Any offer of employment for this role may be conditioned on the Company's ability to provide the candidate with access to such technology or source code in compliance with applicable U.S. export control laws, which may require the Company to seek government authorization.
