Customer Success Engineer

ABOUT E2B

E2B is a fast-growing Series A startup with 8-figure revenue. We've raised over $37M since our founding in 2023. Our customers include companies like Microsoft, Perplexity, Hugging Face, Manus, and Groq. We're building the next hyperscaler for AI agents.

ABOUT THE ROLE

We are looking for our first Customer Success Engineer to lead post sales efforts and ensure that customers are getting the best utility possible from E2B.

E2B's customers split between thousands of self-serve developers and a small set of enterprise accounts running production AI agents. We offer plans to self serve users as well as enterprise users. This role owns both.

Half your week is inside our usage data. Write queries that surface cold accounts, silent churners, and healthy-looking accounts about to hit a limit. Reach out, figure out what's blocking them, fix it or escalate. The other half, you're the named technical contact for a portfolio of enterprise accounts. You know their use cases, their architecture, their on-call team. Questions get answered. Issues get triaged before they become Slack escalations.

WHAT YOU'LL DO

• Build and maintain the customer-health view. Create and monitor dashboards against our usage data, define the signals that mean "lagging" or "at-risk," surface the right accounts each week.
• Build automated, proactive outreach to weak self-serve accounts. You’ll build and run these systems within your first month
• Manage a portfolio of named enterprise accounts as their primary technical contact. Know their workload, their team, their integration. Be the person they DM first.
• Run customer activity through Salesforce. Account notes, contact records, activity logs, health scores.
• Triage technical issues before they escalate. Reproduce, gather logs, narrow it down. When something genuinely needs engineering, hand off a clean repro, not a customer transcript.
• Catch patterns across the customer base. If five customers hit the same friction point in a week, that's a product signal. Surface it in the right channels with data, not vibes.
• Partner with Sales. They own the dollars; you own the technical relationship. When they need someone in a customer call who can answer the deep question, you're that person.
• Build internal tooling for yourself. Health-score dashboards, recurring queries, saved reports. If something is repeatable, automate it.

WHAT WE'RE LOOKING FOR

• 3+ years in a customer success, customer engineering, or technical account management role at a B2B SaaS or developer-tools company.
• Strong written and verbal communication. Hard requirement, not a nice-to-have. Most of the job is talking to customers, internally and externally, in writing and on calls.
• Comfortable in Salesforce as your primary daily tool. Account management, activity tracking, dashboards.
• Customer-first instinct. You've made someone successful before, you know what that looks like, and you're not phoning it in.
• Excited to work in person from San Francisco.

NICE-TO-HAVE

• SQL fluency. Big lift if you can write your own queries against the usage warehouse instead of waiting on a data team. The signal you build to find lagging accounts will only be as good as your ability to define it yourself.
• Background in developer tools, infrastructure, AI/ML, or any product where the customer is technical. The conversations are different when the person on the other end can read the API docs faster than you can.
• Familiarity with usage-based / consumption pricing models
• Past contributions to documentation, knowledge bases, or customer-facing internal tooling.

WHAT IT’S LIKE TO WORK AT E2B

We’re a fast-growing startup with in-person (4 days on-site, 1 day WFH) offices in San Francisco and Prague, Czech Republic. We already generate 8-figure revenue and work directly with top-tier AI companies like Perplexity, Hugging Face, and other exciting teams pushing the frontier of AI.

We cover full healthcare, vision, and dental insurance, and offer unlimited PTO.
