Lead Customer Success Engineer
About the role
Based in New York City, Flint is looking for a Lead Customer Success Engineer to build the systems behind our Customer Success function. We have two strong beliefs about Customer Success. First: CS is a revenue function. The job is not just to make customers happy. It is to drive adoption, retention, expansion, and ultimately NRR. Second: much of traditional CS should be automated. A growing customer base should not require headcount to grow at the same rate. We want to automate everything around the customer relationship that does not actually require a human. The more we can automate, the more human interaction we can have with teachers where it actually matters.
Responsibilities
- Company-wide NRR, with a target of 110%+
- Customer health, churn signals, expansion signals, and renewal forecasting
- Automated onboarding, adoption, renewal, and expansion workflows
- CS tooling, reporting, internal tools, and automations
- Systems that make the wider CS team more efficient to ensure they hit their metrics
- Technical escalations for complex customer problems
- Understanding why customers retain, expand, or churn and turning those lessons into repeatable systems
- Ensuring that other customer success team members know how to interact with and use the system
Qualifications
- Background in Customer Success or any role requiring high ownership for commercial outcomes
- Experience working in a startup or other high‑intensity, ambiguous environment
- Proven track record of building technical systems; hands‑on experience with tools such as Claude Code, Cursor, or similar
- Commercial mindset with a desire to be accountable for revenue outcomes
- Natural inclination to identify automation opportunities
- Comfortable working directly with customers when needed
- Able to move fluidly between customer problems, data, workflows, and technical systems
- Preference for ownership and ambiguity over mature playbooks
Pay
$140,000 - $160,000 base + $20K target variable (with accelerators for over-performance) + equity
