About The Position

About Composio
At Composio, we are building infrastructure that lets AI agents communicate with the tools people use for work, including GitHub, Gmail, Notion, Salesforce, and many more. We are a dosmall team working on the messy problems between agents and real-world software: context, auth, tools, search, permissions, reliability, and developer experience. The goal is simple: make Composio the most capable bridge between agents and the tools they need to get work done.
We raised a $25M Series A from Lightspeed, with angels including Guillermo Rauch (CEO of Vercel), Dharmesh Shah (CTO of HubSpot), and Gokul Rajaram). We have 500K+ customers ranging from individual developers to YC teams to companies like Glean, Zoom, AWS, Airtable and more.
About the role
Our largest customers are betting meaningful parts of their AI infrastructure on Composio. They need a dedicated partner who deeply understands their use cases, anticipates their needs, and makes sure they get extraordinary value out of the platform, not just at launch, but at every stage of their journey with us.
This is Composio's founding CSM role. You'll own a book of our highest-value enterprise and growth accounts, build the relationships that turn customers into champions, and create the CS processes and playbooks that scale as we grow. You'll sit at the intersection of product, engineering, and sales, and your fingerprints will be on how Composio does customer success for years to come.

Requirements

• 4–7 years in a Customer Success or Technical Account Management role at a developer tools, infrastructure, or API-first SaaS company
• Proven track record owning NRR and renewals for enterprise accounts: you've grown a book, not just maintained one
• Technical fluency: you don't need to write production code, but you need to understand APIs, integration patterns, and how engineering teams build and ship; you can hold a substantive conversation with a staff engineer
• Experience with complex, multi-stakeholder accounts: you know how to navigate a large org, find the real decision-maker, and maintain relationships at multiple levels simultaneously
• Builder mindset: you've created CS processes from scratch before, not just followed a playbook handed to you
• Strong commercial instincts: you treat every account as a revenue opportunity and approach renewals and expansions with the same rigor as new sales
• Excellent communicator: equally comfortable presenting a QBR to a VP of Engineering and escalating a technical issue to your own engineering team
• Excited about agentic AI: you're curious about what customers are building and bring genuine enthusiasm to helping them push the boundaries of what Composio can do

Responsibilities

• Manage a book of Composio's largest enterprise and growth accounts: serve as their primary point of contact and internal advocate
• Lead structured onboarding for new enterprise customers: ensure fast time-to-value, clean technical integration, and clear success metrics from day one
• Drive deep product adoption: understand each customer's AI use cases and help them expand usage across teams, integrations, and workflows
• Own NRR for your book: proactively identify expansion opportunities, lead renewal conversations, and partner with AEs on upsells and cross-sells
• Build executive relationships: maintain multi-threaded relationships across champion, economic buyer, and technical decision-maker at each account
• Serve as the voice of the customer internally: bring patterns, friction points, and product gaps from the field directly to product and engineering
• Run a structured QBR cadence with top accounts: review usage, align on roadmap, and surface strategic opportunities on both sides
• Build the CS playbook from scratch: onboarding frameworks, health scoring, escalation protocols, and renewal processes that scale as the team grows
• Partner with Support to ensure enterprise customers receive fast, high-quality resolution on technical issues

Benefits

• Competitive salary, commission, and equity
• Medical, dental, and vision coverage
• Flexible time off
• AI/tooling stipend
• High-agency environment with direct access to founders, engineering, and product
