MongoDB is standing up a dedicated ISV Partnerships function, and this Director role is the leadership seat at the center of that effort. You will own the strategy and execution of MongoDB's ISV partner program across a team of partner managers, covering both industry-specific ISVs in verticals like financial services, healthcare, insurance, retail, and manufacturing, and horizontal AI-native ISVs building platforms and tools that serve builders across industries. This is not a role for someone who wants to manage from a distance. You will set the strategic direction for how MongoDB identifies, activates, and scales ISV partnerships, while staying close enough to the work to directly influence key relationships, shape partner agreements, and coach your team through complex deals. You will be expected to operate as a player-coach: intellectually involved in the most important partnerships, hands-on when the moment calls for it, and consistently raising the bar for what good looks like on your team. This is a greenfield program. You will have real ownership over how it is built, the methodology your team follows, how success is defined and measured, and how the function earns credibility with Sales, Product, and executive leadership. The opportunity is significant for the right leader. This role can be based remotely in the United States. What You'll Do Strategy and Program Leadership Define and own the strategic framework for MongoDB's ISV partner program, including segmentation across vertical and horizontal ISV categories, prioritization criteria, and the GTM approach for each partner tier Build and evolve the program infrastructure: onboarding processes, partner playbooks, co-sell frameworks, success metrics, and the internal operating model that connects ISV partnerships to MongoDB's revenue motion Set the vision for how ISV partnerships contribute to MongoDB's growth, and communicate that vision clearly to executive leadership, cross-functional stakeholders, and

About the team Platform Partnerships builds and grows the relationships that extend OpenAI products through the world’s most important technology platforms. The team works across Product, Engineering, Research, Go-to-Market, Legal, Finance, Marketing, Policy, and Operations to turn partner opportunities into durable product experiences and business outcomes. We are a small team working on opportunities that rarely arrive with a playbook. We set the strategy, make the tradeoffs, and stay close to execution through launch and scale. About the role We’re hiring a Strategic Partner Manager to own and drive the expansion of a portfolio of OpenAI’s most strategic platform partnerships. You will treat each partnership as a business: set the expansion thesis, align joint product roadmaps, structure commercial opportunities, and translate shared ambition into measurable adoption, usage, revenue, distribution, and product impact. This is a senior individual-contributor role with full-lifecycle ownership—from strategy and negotiation through integration, launch, performance, expansion, and renewal. It is a 0-to-1 builder role, not a coordination role. You will create clarity where the operating model is still emerging, make sound decisions with incomplete information, and step into the details required to move the work forward. The right person can move fluidly between a multi-year partnership strategy and the immediate product, commercial, or operating blocker in front of the team. You will build trusted relationships at the executive and working levels while representing OpenAI’s priorities with clarity and thoughtful pushback. What success looks like Each priority partner has a clear expansion thesis, joint roadmap, governance model, and measurable outcomes. High-priority product integrations and go-to-market initiatives launch with clear ownership, strong readiness, and fewer unresolved dependencies. Partnerships show measurable growth across the outcomes that matter for t

About the team The Agent Post-Training team creates the frontier agents OpenAI ships to the world. We are training the models behind our agents in Codex, ChatGPT, the API, and other frontier products: persistent, proactive intelligence that can operate computers, collaborate with people and other agents, and expand what people and organizations can imagine, attempt, and achieve. We define what the next generation of agents should be able to do, build the training signal that teaches those abilities, and run the experiments that make them real. Our work spans coding, tool use, computer use, multi-agent coordination, long-horizon execution, factuality, instruction following, calibrated reasoning, and taste. Our team is where new model capabilities get made. We build the data, environments, graders, training methods, and feedback loops that shape what OpenAI's next agents can do, then carry those capabilities through major training runs and into the products people use. About the Role As a researcher working on Frontier Evals & Environments, you will help build north star model environments to drive progress towards safe AGI/ASI. Your work will directly guide the research programs of the most ambitious training runs happening at OpenAI.
