About Harper
Harper is an AI career agent that puts your career on autopilot. Sync your profile once — by voice or text — and Harper learns your full context, then quietly works the hidden job market for you: we search, you approve. You see only the roles worth your time — full-time, fractional, or advisory — and everything stays private until you say yes. Founded in late 2025 and backed by global VCs, we're a small, fast-moving team in Seoul building the AI recruiter for the global market.

About The Role

• Nothing changes the world faster than the right person on the right problem — and at this stage, that person is you.
• You'll be one of our first engineers, owning Harper's product end to end.
• You ship fast, decide fast, and set the technical bar for everyone who joins after you.

What You'll Do

• Build Harper's product end to end — candidate experience, recruiter ops, web app, dashboards — from idea to production.
• Own features outright: scope, design, ship, and iterate with real users in days, not months.
• Set the engineering standards, architecture, and velocity for the founding team.
• Work directly with the founders on what to build next.

Who You Are

• 3+ years building production web apps — you've shipped things real users depend on.
• Strong across the stack: modern frontend (React/Next) and backend (Node/Python/Go), with solid data modeling.
• You move fast in ambiguity and care about the product, not just the code.
• High-agency: you'd rather own an outcome than wait for a spec.

Why Join (and what you'll get)

• Real founder-level ownership. You're an owner and co-creator from day one — you set the architecture, the bar, and the pace from zero.
• The fastest growth of your career. You'll build more, decide more, and ship more in a year here than most engineers do in five.
• A front-row seat to company-building. Daily, direct work with the founders at startup speed — you'll see every part of how a startup is made.
• Build category-defining AI at the exact moment the market is being created.
• Significant founding-team equity.
• Breakfast, lunch, dinner, and coffee — all on us.
• Seoul, on-site — high-bandwidth, in-person, move-fast culture.
• Team retreats abroad — we work hard, then explore the world together (think Bali, Lisbon).
