About the team
GTM Engineering builds the AI agents, systems, and automation that power how go-to-market teams work, spanning Identify, Build, Enable, and Evangelize.
Responsibilities
- Monitor production health across every graph, catching errors, slow runs, expensive runs, and silent failures.
- Triage incoming issues from Slack, tickets, and rep reports, fixing small things directly and routing the rest.
- Run the weekly eval suite, investigate failures, and turn production bugs into permanent regression tests.
- Track cost and latency by model, graph, use case, and role, and recommend changes to model choice, reasoning effort, and caching.
- Track usage and adoption per rep and per feature, and own the weekly health report.
- Build business metrics showing the agent's value, from reply rates and meetings booked to hours reclaimed and ROI.
- Build monitoring and alerting on LangSmith, and write the "how we run our own agent" story for customers.
Requirements
- Strong production Python and SQL, comfortable working in traces, logs, and warehouse tables.
- Real experience running LLM applications, including tracing, evals, and prompt and cache mechanics.
- SRE or production operations instincts: percentiles, SLOs, separating noise from real pattern.
- Healthy skepticism about metrics.
- Clear writing, and interest in publishing what you learn.
- High agency.
- Nice to haves: LangGraph or LangSmith experience, experience building an eval suite from scratch, BigQuery or dbt, prior DevRel-adjacent writing, empathy for sales and go-to-market users.
Conditions
- Salary: $150,000 - $190,000.
- Compensation includes base salary, variable compensation, meaningful equity, benefits, and perks.
- Benefits include medical, dental, and vision coverage, flexible vacation, a 401(k) plan, meals on in-office days in the US.
