Support Engineer

We raised a $250M Series C to build the search engine for AIs. Led by a16z, with existing investors Benchmark, Lightspeed, and YC doubling down, the round brings Exa's valuation to $2.2 billion.

Exa is building a search engine for the AI era. Our Search API currently powers Agents, Fortune 500s, and AI labs as we transform an industry that hasn't been disrupted since the 90s. We're a largely SF-based team of ~100 from Harvard, MIT, Meta, Google Research, ex-founders, and dropouts alike. We are rapidly building the most intelligent search engine in history. We're high agency, low-ego, and united by the feeling that this is one of the last problems worth getting right.

Support Engineers make sure every committed Exa customer gets their problem solved, fast, around the clock. We run support AI-first: AI tools like Pylon and agents triage tickets, answer them and resolve what they can. You take on what the AI can't: the hard, ambiguous technical problems that need a real engineer.

You'll have the same technical depth as our Forward Deployed Engineers. You'll dig into the API, SDKs and customers' integrations, reproduce bugs, and open pull requests with fixes for our engineers to review. When a problem truly needs Engineering, you escalate it with everything they need to act, and you stay the customer's point of contact until it's resolved. This is not a script-reading role. You are an engineer who owns the fix.

Build the support system: configure our Pylon instance and set up robust ticket tracking, SLA tracking and automations that make the support function as efficient as possible

Resolve the tickets the AI can't, troubleshooting across the API, SDKs and customer integrations

Reproduce bugs and fix them, opening pull requests directly for Engineering to review

Escalate to Engineering with full context when you can't solve it yourself: reproduction steps, logs, customer impact and what you've already ruled out

Own every customer follow-up on your tickets, including escalated ones, until the issue is resolved

Make the AI first line better by improving docs, the knowledge base and our Pylon and agent workflows, so more tickets resolve without a human

Keep the follow-the-sun handoff tight: end each shift with an automated handoff that gives the next Support Engineer full context on open tickets

Work with the account team (Account Executives, Forward Deployed Engineers), keeping them informed on tickets from their accounts and flagging account-level risk early

Handle escalation management: watch account health signals, largely through AI, raise every contraction or churn risk to the account team and leadership with requested actions and owners, and follow it until resolved

Spot patterns across tickets and turn them into product feedback and fixes

Have worked as a software engineer, support engineer, solutions engineer or site reliability engineer at a developer-tools, API or AI company

Have built with LLMs, RAG or agents, and can reason about retrieval and search quality

Have built automations or AI workflows that took repetitive work off a team

Like being the person who finally figures out what's going on

Care deeply about the problem of organizing the world's knowledge and making it accessible to machines
