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

  • 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

    • FAQ

    Are these real job opportunities?

    Yes. These are roles companies have asked Harper to help with, and Harper is in direct contact with them.

    Am I applying directly here?

    No. Harper uses information the company has shared privately to assess how well the role fits you. If it looks like a good fit, Harper may recommend you to the company first or ask whether you'd like to move forward with the role first. If you accept, Harper helps make the connection right away. For now, tell Harper which role interests you. Harper will review it first and prepare what it needs to introduce you well.

    How is this different from applying directly to the company?

    You're more likely to reach a meeting, and Harper helps you through the process.

    Will my information be shared with the company?

    You can choose between two approaches. With Exceptional only, Harper shows you a strong opportunity first and shares your profile with the company only after you accept and allow profile sharing. With Open to matches, Harper may introduce your profile to a company first when there's a strong fit. This can lead to more opportunities, and you can review the company's proposal before deciding whether to move forward.

    What if I'm not looking to move right now?

    That's fine. Tell Harper you're not planning a move right now. You can look at a proposal you like and decide then.

    What happens after I accept a role?

    Harper prepares your profile and relevant experience for an introduction to the company and helps make the connection. Your profile is shared according to your settings and consent, and Harper keeps you updated by email.
