Why Cast AI?

CAST AI is an automation platform that runs cloud-native and AI infrastructure at scale — using autonomous decision-making to optimize Kubernetes and cloud environments, replacing manual tuning with continuous automation. Over 2,100 companies rely on us, including Samsung, KT, SK Telecom, Kakao, Akamai, BMW, Cisco, and Hugging Face.

Global team, diverse perspectives
We’re headquartered in Miami, but our impact is international. We take a global and intentional approach to diversity. Today, Cast AI operates across 34 countries spanning Europe, North America, Latin America, and APAC, bringing a wide range of perspectives into how we build and lead. 

Unicorn momentum
In January 2026, CAST AI crossed unicorn status ($1B+ valuation) on a strategic investment from Shinsegae Group’s venture arm. Korea is a priority market as a result — this is a ground-floor seat building the local GTM alongside the Country Manager, not stepping into an existing playbook.

Join us as we build the future of autonomous infrastructure.

About the role

Drive new business and expand CAST AI’s footprint across Korea’s largest enterprises, selling a technical, consumption-priced infrastructure automation platform (Kubernetes cost optimization, autoscaling, GPU/AI infrastructure optimization) into buying committees spanning engineering, DevOps, finance/FinOps, and procurement.
We’re looking for 10+ years of enterprise software/SaaS sales experience, with a track record closing complex, multi-stakeholder deals at large Korean enterprises and multinational subsidiaries in Korea.

Requirements:

  • 10+ years as an Account Executive/enterprise sales professional, consistently hitting quota selling into large Korean enterprises.
  • Experience selling cloud SaaS or infrastructure software (Cloud Infrastructure, FinOps, Cloud Security, Observability, or DevOps/Platform Engineering).
  • Working knowledge of Kubernetes and public cloud (AWS/GCP/Azure) — enough to run credible discovery with engineering buyers.
  • Proven use of MEDDIC/MEDDPICC or a comparable value-selling methodology.
  • A hunter mentality — proven ability to build new-logo pipeline, not just manage an inherited book.
  • Fluent Korean (native/near-native) and strong professional English.
  • Executive presence with CIOs/CTOs/Finance leadership.
  • Strong CRM/forecasting discipline (Salesforce or equivalent).
  • Self-starter comfortable building process in an early-stage market, not waiting for one to exist.

Responsibilities:

  • Own full-cycle sales for your Korea territory — outbound pipeline through negotiation and close.
  • Prioritize new-logo acquisition alongside expansion of existing accounts.
  • Run Opportunity Assessment → Value Discovery → Value Demonstration → Value Delivery.
  • Navigate multi-threaded deals (CIO, CTO, VP Engineering, FinOps) typical of Korean chaebol and platform companies.
  • Build executive-level business cases and ROI models tailored to each account.
  • Run technical discovery and executive business reviews, partnering with Sales Engineering on demos and POCs.
  • Maintain rigorous pipeline hygiene and forecasting discipline in the CRM.
  • Represent CAST AI with partners (AWS/GCP/Azure, local SIs) and at industry events.
  • Help shape Korea GTM strategy and messaging as an early team member, alongside the Country Manager.

Nice to have:

  • Existing account context within Korean conglomerates, retail/e-commerce, gaming, platform, manufacturing, or financial holding companies.
  • Hyperscaler co-sell (AWS/GCP/Azure) or local SI partner experience.
  • FinOps Foundation certification or familiarity with the FOCUS framework.

What’s in it for you?

  • Ground-floor seat with direct visibility to regional/global leadership.
  • Competitive base + uncapped commission.
  • Equity in a recently-minted unicorn.
  • Remote-first, flexible working environment.
  • L&D budget, home office allowance, team-building budget.

Hiring Process:

  • Recruiter/Country Manager screen
  • Hiring Manager interview
  • 1–2 additional interviews (regional sales leadership, SE panel)
  • Culture Check interview with an executive

*As part of our standard hiring process, we would like to inform you that a background check may be conducted at the final stage of recruitment through our third-party provider, Checkr.
*Please note that Cast AI does not provide any form of visa sponsorship/work permit.
