About VESSL AI

Founded in Seoul and now expanding to the U.S., we are a Series A company ($12M raised, ~40 people) backed by top-tier investors in Korea. We serve AI-native startups, research labs, and enterprises.

VESSL AI is the GPU orchestrator for experimenting, building, and scaling AI models across multi-cloud and on-premises environments, the vessel for both experimentation and scalable AI.

Role Expectation

You will be working side-by-side with our Founding GTM team to launch and scale our U.S. business. This is not a defined playbook role, this is for someone who wants to help write the playbook.

You’ll operate across sales, customer success, partnerships, marketing, and operations; whatever moves the needle. You’ll wear multiple hats, dive deep into ambiguous problems, and directly shape our go-to-market engine in a high-stakes environment.

Key Responsibilities

• Go-to-Market Execution – Run lead generation experiments, manage the sales stack, support early deals, and continuously refine messaging and pitch.
• Customer & Market Insights – Onboard users, gather feedback, troubleshoot issues, and identify GTM opportunities through customer research and data.
• Content & Community – Create sales collateral, support events and demos, and help grow VESSL’s presence in the U.S. AI ecosystem.
• Strategic & Operational Support – Contribute to fundraising, partnerships, compliance, and internal ops to keep the U.S. team running smoothly.

Note: The scope and responsibilities of this role will evolve based on the company’s growth stage and emerging priorities. Flexibility and adaptability are key.

Who We Expect

• You have 0-2 years of experience in early-stage startups, consulting, or investment banking and you’re hungry for a more hands-on, creative role.
• You’re an exceptional communicator who is concise, persuasive, and quick on your feet.
• You take ownership and thrive in chaos. You’re not afraid to roll up your sleeves and do unglamorous work to make things move.
• You think in systems and are obsessed with making things scalable, repeatable, and documented.
• You’re analytical and structured, constantly balancing qualitative insights with quantitative rigor.
• Bonus: Understanding of AI/ML market dynamics and B2B software sales cycles.
• Fluent in both Korean & English.

What You Should Expect

• A front-row seat to building a U.S. business from scratch with daily exposure to founder-level strategy, GTM experiments, and high-velocity execution.
• Clear impact. You’ll see your work directly reflected in pipeline, partnerships, product direction, and brand.
• Speed. We MUST move fast, learn fast, and iterate constantly.
• High trust, high expectations. We’ll treat you like an owner and expect you to act like one.
• A team that values clarity, curiosity, and craft and deeply cares about building category-defining software.
• In-person work culture. We’re early, and we believe the fastest way to win is together, in the room. Expect a minimum of 60 hours per week.
• Comp & Benefits. Salary: 100k-125k + equity / Healthcare benefits / 401K / Unlimited PTO / Lunch provided

If this sounds like you, and you’re excited to build a company — not just work at one, we’d love to chat.
