Prime Intellect is building the open superintelligence stack: the infrastructure frontier AI labs build internally, made available to every ambitious AI team.
Our platform, Lab, unifies compute, environments, evaluations, secure sandboxes, high-performance training, and deployment into one full-stack system for post-training at frontier scale - from SFT and RL to tool use, agent workflows, and continuously improving production models. We are building open frontier AI: open-source models trained end to end for long-horizon tasks like autonomous research, and the full-stack platform our own research team uses to build them. The next generation of AI companies, enterprises, and research teams do not just need more GPUs. They need the ability to turn their own workflows, tools, data, and feedback loops into superintelligence they own.
Prime Intellect has raised $150M in total funding from Founders Fund, Radical Ventures, NVIDIA, and exceptional AI, infrastructure, and enterprise operators — including Andrej Karpathy, Dwarkesh Patel, and leaders and founders from Ramp, Perplexity, Harvey, Mercor, Zapier, Datadog, Cognition, OpenAI, Thinking Machines, Together AI, SemiAnalysis, LangChain, Browserbase, Cloudflare, Sierra, Databricks, Airbnb, OpenRouter, Standard Intelligence, Fleet, Core Auto, and more. We are looking for people who want to build at the intersection of frontier research, real infrastructure, and go-to-market for a category that does not fully exist yet.
Your Role
Prime Intellect serves some of the most sophisticated AI teams in the world that depend on our compute and infrastructure to train and deploy production AI systems. The Customer Success Manager is the person who makes sure those customers succeed, scale, and keep building with us.
This is not a traditional Customer Success role. Our customers run large-scale training jobs, scale inference workloads against real production traffic, and depend on cluster reliability and performance the way most companies depend on their cloud provider. The work spans the technical and the commercial — you'll be reading Grafana dashboards and discussing cluster performance with a customer's ML infrastructure team in the morning, and partnering with Sales on a capacity expansion in the afternoon.
You'll own a portfolio of enterprise customers end-to-end and build the relationships that make Prime Intellect the partner of choice for their AI infrastructure.
Responsibilities
Customer Ownership
Own a portfolio of enterprise customers end-to-end — adoption, retention, expansion, and overall health
Build deep relationships with technical and executive stakeholders at each customer, from ML engineers to engineering leadership
Drive customer outcomes: faster time-to-value on first workloads, smooth scaling as their usage grows, and meaningful expansion as their AI ambitions expand
Technical Partnership
Understand each customer's training and inference workloads at a real technical level — what models they're training, what infrastructure they need, what their performance bottlenecks are
Partner with customers' engineering teams on cluster performance, capacity planning, workload optimization, and migration
Translate customer needs into clear, prioritized feedback for our Engineering and Product teams
Expansion & Renewals
Identify expansion opportunities ahead of the customer — anticipate scaling needs, surface new use cases, drive adoption of new products (Lab, Inference, additional compute capacity)
Partner with Sales on renewal conversations and growth motions
Maintain visibility into the economics of each customer relationship, in partnership with Finance and Compute
Operational Excellence
Serve as the first line for customer-facing operational issues — usage questions, capacity changes, SLA tracking, incident communications
Build the cross-functional connective tissue between Sales, Engineering, Finance, and customers
What We're Looking For
3–6 years in Customer Success, Technical Account Management, Solutions Engineering, or adjacent roles at infrastructure, cloud, or AI/ML companies
Strong technical fluency — comfortable reading dashboards, discussing infrastructure architecture, and engaging with customer engineering teams without a translator
Strong commercial instincts — you understand that Customer Success is a revenue function, not a support function, and you can drive real expansion alongside technical outcomes
Deep customer empathy combined with high judgment — you advocate for customers internally while making the calls that are right for the business
Excellent verbal and written communication, especially when explaining complex technical issues to non-technical stakeholders and vice versa
High ownership — you see gaps and build the fix before anyone asks
Comfortable in ambiguity and speed; this market doesn't slow down
AI-native in how you work: you use LLMs, automation, and programmatic tools to move faster
Bonus:
Direct experience at a cloud provider, AI infrastructure company, or compute marketplace
Familiarity with GPU economics, training and inference workloads, or compute consumption patterns
Background as a TAM or Solutions Architect at a hyperscaler (AWS, GCP, Azure) or specialized cloud provider
Working knowledge of usage-based pricing, capacity commitments, and consumption-based contracts
You've been an early Customer Success hire at a high-growth company
What We Offer
Cash Compensation Range of $160,000 – $200,000 + meaningful equity
Flexible work (remote or San Francisco)
Visa sponsorship and relocation support
Professional development budget
Team off-sites and conferences
A front-row seat to building the infrastructure layer for open AI
