• Relational database & caching skills (MySQL, PostgreSQL, Redis)
• API & microservice design with OpenAPI/Swagger standards
• Asynchronous processing experience using SNS/SQS
• Containerization & CI/CD workflow knowledge (Docker, Git, GitLab CI)
• Fluent English with transparent, solution-oriented communication

Nice To Have:

• Background in e-commerce, checkout flows, or payment processor integrations.
• Experience with cloud platforms, Kubernetes, and application observability/monitoring tools.

We take it as our responsibility to create an environment where everyone feels welcome, exactly as they are.

Different backgrounds and perspectives make us stronger and shape our culture in ways that matter.

What we stand for internally, we stand for as a brand: acceptance, inclusion, and fairness.
