The Role

We're looking for a

AWS infrastructure

• Solid understanding of cloud infrastructure, preferably with serverless architectures and Infrastructure as Code (IaC) tools (e.g. API Gateway, Lambdas, RDS, DynamoDB, IAM, and CDK)
• Passion for building reliable systems with deep knowledge of observability, tracing, and system performance
• Excellent communication skills
• Passion for environmental sustainability.

Preferred Skills

• Mobile application development, including React Native, native modules, Bluetooth Low Energy (BLE), deep linking, and websockets
• Access control systems, such as designing Role-Based Access Control (RBAC) for internal and external applications
• Experience with version control, CI/CD, and build systems (e.g., GitHub Actions)
• Familiarity with compliance and security standards like ISO 27001, SOC 2, GDPR, and CPRA

Benefits
