Job Title

Software Engineer, Agent (Korea)

Location

South Korea, on-site.

Company Description

A platform built to enable every company in the world to build better, more human customer experiences with AI. It partners with industry leaders across telecommunications and media, commerce, financial services, and healthcare. Primarily an in-person company based in San Francisco, with growing offices across North America, Europe, and Asia — and now opening in Korea.

Its co-founder currently serves as Board Chair of OpenAI. Previously he was co-CEO of Salesforce and CTO of Facebook.

The company raised close to $1B in its most recent round, at a valuation above $15B.

What You'll Do

  • Design and deliver production-grade AI agents: You'll build and ship highly performant, reliable, and intuitive AI agents that are central, mission-critical and drive revenue directly to the company's growth. These aren't prototypes — they are powerful, scalable systems running in production environments across industries like finance, healthcare, and commerce.

  • Drive the Agent Development Life Cycle (ADLC): You'll have complete ownership and autonomy from initial pilot through deployment and continuous iteration. You'll be responsible for building, tuning, and evolving AI agents in production environments, defining the standard for ADLC best practices along the way.

  • Partner with large enterprises and cutting-edge startups: You'll work directly with leaders at some of the world's largest enterprises to understand their most pressing business challenges, and build AI agents that transform how they operate at scale. You'll also partner with the most cutting-edge startups, embedding AI agents across their entire business stack to drive innovation and efficiency.

  • Build the future of the platform: Your direct work with customers will guide the evolution of the company's core platform. You'll surface unmet needs, prototype new tools and features, and collaborate with research, product, and platform to shape the future of AI agent development and the product.

Example Projects

These are some examples of projects that engineers on the team have worked on recently:

  • Design and build AI agents for large telecommunications and media companies that consistently outperform human agents in managing subscription churn

  • Develop and refine AI agents capable of navigating complex customer interactions, like troubleshooting a broken device and personalizing product recommendations

  • Create generalizable AI agent frameworks tailored for industry-specific use cases

  • Facilitate design partnerships for new product initiatives, such as new agent architectures, self-service capabilities, and generative agent development

  • Experiment with the latest voice models and figure out how to integrate them at scale to enterprise-grade customers

Who You Are

  • Experience building and scaling end-to-end production systems

  • Strong technical problem-solving skills, especially in fast-changing, ambiguous environments

  • A builder and tinkerer's mindset with high agency — you find creative ways to overcome obstacles and ship

  • Comfort working directly with customers to understand their needs and solve real-world problems

  • Strong English and Korean communication skills — clear, direct, and persuasive across technical and non-technical audiences

Even better

  • Experience building or deploying AI/LLM systems in production

  • Have been a founder or founding engineer — you know what it means to balance craft, ownership, and speed

  • Familiarity with tools that power today's AI agents: eval frameworks, agent tooling, RAG pipelines, and prompt engineering

  • Prior experience with React, TypeScript, and/or Go

  • Previous roles where you interfaced with customers or led technical projects with external stakeholders

Why Join

The company offers the following to full-time employees:

  • Flexible (unlimited) paid time off

  • Medical, dental, and vision benefits for you and your family

  • Life insurance and disability benefits

  • Retirement plan dependent on country of employment
