What to Expect:
We are looking for a Customer Success Director to join Ion Q’s Customer Success team. In this role, you will act as the post-sales “site lead” for South Korea, owning the health of the client relationships and contract after deal close: ensuring the contract is executed as agreed, stakeholders stay aligned across multiple workstreams, and the customer fully adopts and consumes Ion Q’s platform.
You’ll play an important part in shaping the operating rhythm, reporting, and cross-functional coordination required to deliver a successful customer experience in a high-ambiguity, highly technical environment.
What You'll be Doing:
In this position, you will drive top-down post-sales program management across interconnected workstreams (e.g., system build, facilities/data centre readiness, networking, platform support), keeping Ion Q and the customer aligned on milestones, risks, and dependencies. You’ll help translate the contract into an executable plan, remove adoption blockers, and ensure the customer realizes value from the partnership.
You’ll have the opportunity to increase adoption and consumption, improve customer and contract satisfaction, and help position South Korea as a scalable growth region for Ion Q over time.
Key responsibilities include:
Own adoption/consumption for clients: onboard users to Ion Q Quantum Cloud, track usage, and drive adoption.
Run post-sales execution as the single accountable lead: interpret contract + verbal expectations, coordinate workstreams, and manage risks/issues to keep delivery on track.
Lead stakeholder management and monthly reporting: provide clear updates on adoption, satisfaction, contract health, and expansion signals to internal and customer stakeholders.
Be the in-region “translator”: combine cultural fluency and technical credibility to win trust with a very technical, government/academic customer environment.
Build the customer success operating system for the account: create success plans, QBR cadence, stakeholder maps, and playbooks that make delivery repeatable (not hero-driven), then keep them current as scope evolves.
Voice of Customer → internal action: translate client needs into crisp requirements and prioritisation for Product/Engineering, then close the loop with the customer on what’s changing, when, and why.
Requirements
To be successful in this role, you will need strong experience leading complex, cross-functional customer programs in a technical environment, plus the judgement and presence to navigate ambiguity, read the room, and keep both Ion Q and the customer aligned. You should be comfortable working with technical teams, understanding platform usage signals, and ensuring we deliver to the letter and spirit of the contract.
You’d be a great fit with:
Fluent Korean and ability to be based in South Korea with 3 days/week on-site expectation.
Proven program / project leadership across multiple dependent workstreams (delivery, onboarding, facilities/ops, technical stakeholders).
Enough technical credibility to work with quantum/HPC-adjacent stakeholders (HM preference: advanced degree in Physics or related STEM).
Strong customer exec presence + contract discipline (manage expectations, prevent delivery/contract misalignment, drive satisfaction).
Demonstrated ability to drive measurable adoption/consumption in a platform/technical product environment (can point to usage lift, retention improvement, or time-to-value reduction). Strong cross-cultural stakeholder leadership with evidence of navigating Korean institutional contexts (government, research, or large enterprise), balancing diplomacy with firmness when commitments slip.
Benefits
Be part of a team that’s shaping the future of quantum. We offer more than just a role, you’ll join a world class community of scientists, engineers and innovators working to unlock the full potential of quantum computing.
We offer a range of benefits, including opportunities to further your career alongside industry leaders, a competitive salary with Ion Q stock options, an annual performance bonus, generous annual leave, flexible hybrid working, private medical and dental insurance for you and your family, and much more.
Join us and be part of the future of quantum computing.
We’re proud to be an equal opportunity employer and welcome applicants from all backgrounds.
