AWS-02 · CCoE Cloud Architect — Architecture & Security
About The Position
The role Megazone US is an AWS Premier Tier Services Partner and part of MegazoneCloud, headquartered in Seoul. This seat joins a dedicated 22-person team delivering a multicloud managed service — AWS, Azure and Google Cloud across roughly 155 cloud accounts — to a major automotive enterprise client and its business units. You are the architecture and security authority inside the client’s Cloud Center of Excellence: you set the standard for how AWS accounts are built and secured, you review what the business units want to deploy, and you are the person who decides whether a design is safe to run.
Requirements
- 7+ years in cloud infrastructure, including 4+ years designing on AWS at enterprise scale (multi-account, multi-VPC).
- Demonstrable ownership of an AWS multi-account landing zone — Control Tower or an equivalent custom build — including guardrails and account vending.
- Deep AWS security: IAM policy design, SCPs, KMS, VPC security architecture, centralized logging and the AWS security services.
- Track record of governing other teams’ designs: architecture review, standards enforcement, saying no constructively.
- Professional working fluency in Korean and English.
- Able to work onsite in Irvine, CA.
- Must be authorized to work in the US (sponsorship to be confirmed by Megazone US HR), able to pass client background screening, and able to work within our SOC 2 control environment.
Nice To Haves
- AWS Solutions Architect Professional or Security Specialty
- MSP or consultancy background
- Automotive, manufacturing or Korean-affiliated enterprise experience
- SOC 2 / ISO 27001 / NIST control mapping
- Working knowledge of Azure and Google Cloud security
Responsibilities
- Own landing-zone and account architecture standards — account structure, organizational units, networking, identity, logging and guardrails.
- Review business-unit architectures and change requests, and approve, reject or improve them against the standard.
- Own security architecture: IAM and least privilege, encryption, boundary protection, secrets handling and the security baseline every account is measured against.
- Drive vulnerability and compliance posture across the estate (Security Hub, GuardDuty, Config, Inspector) and push remediation through the operations team.
- Produce the reference patterns and documentation that platform and operations engineers build from.
- Act as senior technical escalation for architecture and security incidents.
- Explain architecture and risk decisions to Korean-speaking client and HQ stakeholders, in writing and in meetings.
Benefits
- Your growth is our growth.

- Your voice and designs will directly shape our technical roadmap and our clients' success.
- You'll work on the latest tech to solve real problems.
- We believe mistakes are learning opportunities, not failures.
- We seek diverse talent who are ready to make an immediate impact.
