仕事内容
About the position
As a senior security engineer at MeetsMore, you'll join the SRE team and cover four areas: penetration testing of our own products, application security in the development process, AI security—covering both our LLM-powered features and our AI-assisted development process—and the technical side of security compliance: implementing controls, automating evidence collection, and answering the engineering questions in audits and customer security checks.
You will be building the security team and leading the security effort across the company. You'll work alongside an SRE / DevOps team that automates as much as possible. Communication is mostly in English and occasionally in Japanese, with support from translation tools.
Our Tech Stack
Not exhaustive, but the most important are:
TypeScript everywhere.
NodeJS.
React.
MongoDB.
AWS (Specifically ECS, CloudFront, S3, SQS, Lambda)
Vercel.
Redis.
