Software Engineer, AI Agent
Sendbird, Seoul, South Korea
The role
You'll own end-to-end delivery of core AI agent capabilities, from architecture to production, driving excellence across orchestration, prompt engineering, and platform scalability. You'll mentor the engineers around you and set the standard for AI-native development. This role is built for someone who moves fast, thinks in systems, and uses AI to ship at a pace that surprises people.
What you need
- You've owned a system that broke in production, made it better, and still think about why it broke.
- You use agentic tools like Claude Code or Codex as a core part of your dev workflow, not as a novelty.
- You enjoy mentoring junior engineers not because it's expected, but because you genuinely care about how they grow.
- You've shipped LLM-powered features into production and have strong views on where prompt engineering ends and architecture begins.
- You've led technical planning in a cross-functional setting and can hold your own in a room with PMs, designers, and engineers at once.
