Software Engineer, AI Agent

Summary

Sendbird is on a mission to build the AI workforce of tomorrow, focusing on enhancing customer experience through AI technology. The Software Engineer for AI Agents will be responsible for deploying production-grade AI agents tailored to customer environments, ensuring they perform effectively in real-world scenarios.

Responsibilities

• Deploy production-grade AI agents tailored to each customer's environment, owning setup, configuration, and go-live
• Tune system prompts and agent behaviors against real-world use cases, using AI-assisted workflows to move from hypothesis to working solution faster than a traditional dev cycle allows
• Prototype and ship fast, leveraging agentic coding tools to build agent interfaces, dashboards, and backend integrations with Next.js, React, and modern APIs
• Integrate RAG pipelines and knowledge bases that give agents the context they need to perform
• Monitor live deployments with logging, metrics, and observability so issues surface before customers notice them
• Collaborate with Forward Deployed PMs, core product, and design to turn customer needs into working solutions, often building a prototype before the meeting ends
• Lead technical demos, document implementation decisions, and maintain architecture diagrams that actually reflect reality

Skills

• 2-3 years of hands-on software engineering experience in full-stack or backend development
• Strong Python proficiency and the ability to write clean, maintainable code under real-world constraints
• Practical experience with React and modern JavaScript/TypeScript on the frontend, plus backend frameworks like Node.js, Django, or Express
• Hands-on experience with LLM APIs (e.g., OpenAI, Claude) or agent frameworks such as LangChain
• Familiarity with RAG pipelines, knowledge base integration, and cloud deployment platforms (e.g., AWS Lambda, Vercel, GCP Cloud Functions)
• Prior experience tuning or debugging AI agent performance in live, production environments - or in a forward deployed setting
• Background in 0-to-1 builds, customer-facing implementation, or technical consulting, with a track record of navigating the messiness of real deployments
