Senior / Staff Backend Engineer - AI Agents Platform

We are looking for a Senior or Staff Backend Engineer with 6+ years of experience to join our AI Agents Platform team to help build our large-scale, highly reliable platform for vertical AI agents. We are seeking a product-minded engineer who is passionate about building scalable, high-performance systems and is excited to contribute to a platform that is revolutionizing an industry by deploying autonomous AI agents.

What you will do:

Own core backend services: Build and operate the agent runtime services (tool execution, state management, orchestration, retries, idempotency, rate limiting).

Design robust APIs and contracts: Develop stable, well-versioned APIs (internal + external), including webhook/event interfaces and integration adapters.

Model complex domain data: Design schemas and data access patterns that support agent memory/state, workflow history, audit trails, permissions, and multi-tenant isolation.

Integrations at scale: Implement and maintain high-quality integrations (OAuth, webhooks, sync engines, connectors) with strong observability and failure handling.

Platform performance and cost control: Optimize throughput/latency, queue backlogs, caching, storage, and inference/tool-call costs; build guardrails for runaway tasks.

Reliability engineering: Define and improve SLIs/SLOs, implement end-to-end tracing, build safety rails (timeouts, circuit breakers, budgets), and run incident response.

Raise engineering standards: Drive code quality, testing strategy, on-call hygiene, runbooks, postmortems, and mentoring.
