Your Tasks

-

- You design and develop our Key Management Service, focusing on secure key generation, lifecycle management (Key Rotation), and high-performance cryptographic operations.

- You implement and optimize complex data flows like Envelope Encryption, managing the relationship between Data Encryption Keys (DEKs) and Key Encryption Keys (KEKs) to provide multi-layered security.

- You develop Kubernetes operators to automate the entire lifecycle of the KMS and Secrets Manager, ensuring the service is self-healing, scalable, and easy to configure.

- You build and maintain robust REST APIs that allow customers to programmatically manage Key Rings, import external keys, and execute signing/verification workflows.





- You take ownership in an "You Build It - You Run It" environment, acting as the bridge between security engineering and SRE.

- You ensure that every cryptographic operation adheres to industry standards (AES, RSA, ECDSA, HMAC) and provides the necessary audit trails for sovereign cloud requirements.

Your Profile

-

- You have a deep enthusiasm for Software Engineering, Applied Cryptography, and Cloud‑Native security.

- You actively own the entire software development lifecycle; go and k8s are your bread and butter—K8s operators are preferably a core part of your engineering toolkit.

- You are familiar with—or eager to master—cryptographic algorithms (AES‑GCM, RSA‑OAEP, ECDSA) and understand the logic behind secure key wrapping and transport.

- You understand that "sovereign" means more than just a location; you understand the auditing and compliance needs of managing secrets in a high‑stakes cloud environment.

- You don't just look at code; you understand how data flows through a system, identifying potential bottlenecks in API body sizes or cryptographic overhead to ensure cost‑efficiency and performance.

- You enjoy discovering new security standards and are excited about sharing your knowledge with the team. xqbhyrx

We look forward to receiving your application.
