Member Technical Staff - Applied AI Engineer (US Timing)

Member of Technical Staff – Applied AI Engineering EXPERIENCE: 2–4 years TYPE: Full-time FOCUS: Applied AI Customer-facing WORK HOURS: US Timings LOCATION: Bengaluru ABOUT THE COMPANY At Composio, we are building infrastructure that allows AI agents to communicate with the tools people use for work, including GitHub, Gmail, Notion, Salesforce, and more. We are a small team of engineers working across context, auth, execution, and reliability to build the action layer for AI agents. We raised a $25M Series A from Lightspeed, with angel investors including Guillermo Rauch (CEO of Vercel), Dharmesh Shah (CTO of HubSpot), and Gokul Rajaram. Our customers range from YC startups to companies like Brex, Glean, Zoom, and more.

This is an applied AI engineering role, not a traditional support role. You will work directly with customers, learn the repeated work behind their problems, and build agentic systems that take that work over. When a customer needs direct engineering, you will debug and ship. When a pattern repeats, you will turn it into a workflow, eval, tool, or product capability that compounds. • The frontier: support is one of the richest applied AI environments — an agent has to gather context, reason across systems, use tools, take bounded action, verify the outcome, and communicate clearly. You design that system. • The trust bar: AI cannot be trusted by default with customer support. You define state, permissions, guardrails, evals, and escalation paths so the automation earns trust. • The feedback loop: it's immediate. Deploy into real support work, watch where the system fails, and improve it until people can hand over more of the job. ROLES AND RESPONSIBILITIES What you'll build • Agentic workflows that take over support functions: intake, classification, context gathering, reproduction, diagnosis, response drafting, remediation, verification, and follow-up. • Tool-using agents that safely inspect runs, logs, auth state, configuration, and provider behavior, then propose or execute bounded recovery actions. • Eval suites for diagnostic correctness, resolution quality, safe escalation, customer communication, and end-to-end task completion. • Human-in-the-loop systems that make ownership, uncertainty, approvals, handoffs, and failure states explicit. • The observability, memory, and feedback loops that let these agents improve from real support cases without repeating mistakes. • Product improvements that remove entire classes of customer issues instead of handling the same symptoms faster. How you'll work • Start with the customer outcome, then work backward into the model, workflow, tooling, or product change required to deliver it. • Own the hardest issues end to end when direct engineering is needed: reproduce, isolate, mitigate, ship, communicate, and verify the resolution with the customer. • Sit with customers and partner with Support, FDE, Product, and Engineering to find work that should become software. • Move from a rough prototype to a reliable production workflow, with traces, evals, guardrails, and a clear human fallback. • Use frontier models, coding agents, and internal AI tools every day to multiply your own engineering output. • Measure success in customer outcomes improved, support work removed, and classes of failure prevented. WHAT YOU'LL BRING • Experience level: 2–4 years of professional software engineering experience. Applied AI engineering • You have built production systems with language models, tool calling, retrieval, structured outputs, multi-step workflows, or agent memory. • You know how to use models and coding agents as leverage, and where their non-determinism creates hidden risk. • You use evals, traces, failure analysis, and fast iteration to make AI systems dependable. Strong systems engineering • You are an experienced backend, platform, or integration engineer who has shipped and operated production software. •
