As a Software Engineer, your mission will be to design, build and maintain critical security services at the heart of Scaleway's cloud infrastructure. You will work on challenging technical topics involving cryptography, Hardware Security Modules (HSMs), key management and secure backend architectures, ensuring the reliability, security and scalability of our services. This is an opportunity to contribute directly to the development of secure, reliable and compliant cloud services, while helping strengthen Europe's sovereign cloud ecosystem. YOUR FUTURE TEAM At Scaleway, we work in a collaborative and international environment where knowledge sharing, technical excellence and diverse perspectives help us build ambitious products at scale. You will join our Secret Service team, composed of 4 people (1 manager and 3 Software Engineers), responsible for developing and operating key security services across Scaleway's cloud platform. The team works at the intersection of backend engineering, cybersecurity and cloud infrastructure, building services that protect sensitive data, manage cryptographic keys and support secure access to cloud resources. You will work in a collaborative environment with a strong focus on ownership, technical quality and continuous improvement, following Kanban practices, backlog refinement and bi-weekly retrospectives. YOUR DAILY ROUTINE * Design, develop and maintain secure backend services powering Key Manager, Secret Manager and Audit Trail. * Build and improve robust, high-performance APIs for cryptographic key management and secure access to sensitive resources. * Work with Hardware Security Modules (HSMs) and integrate cryptographic operations through PKCS#11 interfaces. * Contribute to the architecture and evolution of security-critical infrastructure, with a strong focus on reliability, availability and resilience. * Develop clean, maintainable and scalable software using Go (Golang). * Improve infrastructure automation and deployment processes using Terraform, Docker and GitLab CI/CD. * Implement and maintain observability, monitoring and logging solutions using tools such as Loki. * Work with PostgreSQL to ensure reliable and secure data management. * Contribute to security best practices and compliance requirements, particularly within the SecNumCloud framework. * Collaborate with other Engineering and Infrastructure teams to solve complex security challenges and continuously improve our services.
