core responsibilities for the job include the following:\nBackend and Systems Engineering:\nDesign and build scalable backend services using modern system design principles.\nOwn critical services that manage procurement, invoice, contract, and payment workflows.\nImplement orchestration logic that coordinates AI agents, humans, and enterprise systems.\nBuild resilient systems with strong guarantees around idempotency, retries, and failure handling.\nAPI and Integration Development:\nBuild and maintain robust APIs consumed by AI services, frontend apps, and external systems.\nIntegrate deeply with ERP systems, procurement platforms, and payment gateways and financial rails.\nHandle complex data normalization and transformation across enterprise systems.\nAI Agent Building, Observability, and Testing:\nBuild agent execution runtimes: tool calling, context management, memory, and multi-step reasoning loops.\nImplement multi-agent coordination parallel and sequential workflows with human-in-the-loop escalation.\nInstrument agent execution with full trace capture: tool calls, LLM I/O, latency, token usage, and cost.\nDesign evaluation frameworks for agent output quality, task success rate, and regression detection.\nBuild automated test harnesses for agent pipelines, unit, integration, and replay-based regression tests.\nDefine and track agent reliability metrics: task completion rate, escalation rate, cost per workflow, and SLA adherence.\nReliability, Security, and Compliance:\nDesign systems with enterprise-grade reliability, monitoring, and alerting.\nImplement fine-grained access controls, audit logs, and data security best practices.\nEnsure backend systems meet compliance requirements for financial and regulated data.\nPerformance and Scale:\nOptimize backend systems for latency, throughput, and cost efficiency.\nDesign services that scale across global customers and billions of transactions.\nProactively identify and fix bottlenecks in distributed systems.\nRequirements:\n8-15 years' experience building strong production backend systems.\nStrong proficiency in Python, NodeJS, Go, or similar backend languages.\nDeep understanding of distributed systems, APIs and microservices, databases (SQL and NoSQL), and message queues/event-driven architectures.\nSystem Design:\nProven experience designing scalable, fault-tolerant systems.\nStrong grasp of consistency, concurrency, and data integrity trade-offs.\nExperience building workflow engines or state-driven systems is a plus.","description_format":"text","description_chars":2490,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI
