Description

  • Design, implement, and iterate on LangGraph workflows for requirement capture, clarification loops, stateful routing, and tool orchestration.
  • Build reusable workflow components (nodes, validators, schema-enforced outputs, guardrails) and standard patterns for retries, fallbacks, and human-in-the-loop review.
  • Implement robust tool execution patterns including timeouts, error taxonomy, idempotency, and deterministic structured outputs for downstream automation.
  • Partner with Business Analysts and org leaders during discovery and refinement to translate goals and constraints into sprint-ready tickets and acceptance criteria.
  • Build and maintain agent-callable services/APIs for Snowflake retrieval, operational actions (e.g., Slack/workflows), and data enrichment/packaging.
  • Establish evaluation and observability for agent workflows including golden cases, regression suites, tool mocks, and latency/cost/error monitoring; contribute to pragmatic SLOs.
  • Contribute to the in-house transcription application: transcript ingestion, normalization (timestamps/speaker turns/metadata), storage, and retrieval surfaces for downstream tooling.
  • Improve reliability of transcription pipelines via queue/worker architectures, retries/backoff, idempotency, and replay tooling.
  • Implement rubric-based call scoring with versioned rubrics, explainable outputs, calibration support, and publish scoring artifacts for coaching and operations.
  • Design and implement streaming considerations (session handling, backpressure/reconnect patterns) and ensure clean handoffs between capture, transcription, and scoring stages.

Requirements

  • 3–6 years of software engineering experience, preferably in backend/services roles.
  • Demonstrated production experience implementing LangGraph workflows (required).
  • Strong proficiency in Python and/or TypeScript, including API and service design; experience building production services in a compiled, runtime-stable language (e.g., Go) for high-throughput, low-latency workloads.
  • Strong SQL skills and comfort working with warehouse-backed applications; Snowflake experience preferred.
  • Practical experience shipping LLM applications, including tool/function calling, structured outputs and schema validation, retrieval patterns (RAG), routing/context management, and prompt/version management and evaluation methodologies.
  • Production engineering fundamentals: retries/idempotency, async job patterns, monitoring, cost controls, and SLO-minded design.
  • Strong communication and stakeholder partnership skills, including leading technical discovery and translating business intent into acceptance criteria and implementation plans.
  • Experience with agent builders (Botpress or similar) and packaging tools for agents.
  • Streaming systems and media experience (WebSockets/HTTP2, backpressure/reconnect logic) and audio fundamentals (FFmpeg, codecs) or working with transcription providers.
  • Familiarity with serverless/event-driven architectures (Cloudflare Workers/AWS), queues, and observability platforms.

Benefits

  • Full-time remote / remote-first work environment.
  • Work on a high-scale AI platform that processes billions of API hits and message events.
  • Global, distributed team (1,500+ team members across 15+ countries) providing cross-functional collaboration opportunities.
  • Mentorship and growth opportunities with senior engineers and technical leadership.
  • Equal Opportunity Employer with an inclusive hiring process.
