Software Engineer, Agent Systems (GTM Engineering)

Job summary

Responsibilities

You'll own the health, cost, performance, and business impact of the GTM Agent System, and build the feedback loops that keep it improving. Because we build the platform we run on, you'll also operate the agent on LangSmith the way we tell customers to, and turn that practice into the reference…

• Monitor production health across every graph, catching errors, slow runs, expensive runs, and silent failures before reps report them
• Triage incoming issues from Slack, tickets, and rep reports, fixing small things directly and routing the rest to the right owner
• Run the weekly eval suite, investigate failures, and turn real production bugs into permanent regression tests
• Track cost and latency by model, graph, use case, and role, and recommend concrete changes to model choice, reasoning effort, and caching
• Track usage and adoption per rep and per feature, and own the weekly health report the team runs on

What they're looking for

• 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, and separating noise from real pattern
• Healthy skepticism about metrics; you check what a number actually counts before you publish it
• Clear writing skills, and interest in publishing what you learn
