Build core product workflows (enterprise-grade)

• Implement robust workflow/state systems (approvals, retries, exceptions, audit logs)
• Build internal tooling/admin panels to scale operations and reduce manual effort
• Deliver customer-facing dashboards and reporting experiences

Build and ship LLM/agent capabilities (must-have)

• Implement agentic workflows using LLMs + tools (retrieval, structured actions, messaging sequences, QA checks)
• Build guardrails: policy checks, human-in-the-loop review points, safe fallbacks, and prompt/tool versioning
• Create evaluation & monitoring: offline test sets, automated checks, and online metrics to maintain output quality over time

Integrations + platform plumbing

• Build and maintain integrations via APIs/webhooks
• Own instrumentation: event tracking, data quality checks, and reporting accuracy
• Implement permissions, access controls, and reliability patterns appropriate for enterprise usage

Engineering culture + velocity

• Ship frequently with high quality (tests, code review, CI, observability)
• Collaborate closely with product on discovery, prioritization, and customer feedback
• Contribute to hiring and mentoring as the team grows
