Job Description
The role involves designing and maintaining secure, high-availability backend services for authentication and access management in a cloud environment, focusing on security, reliability, automation, and collaboration within a global team.
Key Responsibilities
- Architect and operate high-availability backend services for authentication, authorization, and certificate management.
- Lead the full service lifecycle from design and threat modeling to deployment, observability, and cost optimization.
- Collaborate with security and product teams to streamline remote access workflows and automate security processes.
- Participate in on-call rotations to maintain system resilience, perform root-cause analysis, and harden infrastructure against threats.
- Develop and evolve Infrastructure as Code (IaC) patterns to enhance security and deployment efficiency.
Requirements
- Proficiency in building and scaling production-grade backend services ideally in Go or Python within AWS or similar major cloud environments, with a focus on API design and system reliability.
- A deep understanding of modern security fundamentals, including PKI certificates, TLS mTLS, OAuth OIDC, and IAM concepts, with the ability to apply defense in depth to distributed systems.
- Hands-on experience with the modern SDLC, including CI/CD pipelines, Terraform or equivalent Infrastructure as Code (IaC), and comprehensive observability metrics, logging, and alerting for mission-critical services.
- Experience in designing and operating high-availability backend services that manage authentication, authorization, and certificate lifecycles to ensure secure access across cloud and appliance environments.
- Experience in leading the full service lifecycle from initial architectural design and threat modeling (STRIDE) to deployment, observability, and long-term cost efficiency.
- Ability to partner with Security Governance and product teams to streamline remote-access flows, translating complex security requirements into automated workflows for engineering teams.
- Participation in a global follow-the-sun on-call rotation, performing root-cause analysis, and hardening infrastructure against emerging threats to maintain system resilience.
- Ability to evolve Infrastructure as Code (IaC) patterns to enforce least-privilege principles, improving security posture and deployment velocity of the ecosystem.
- Strong communication skills to articulate security trade-offs to diverse stakeholders and a willingness to share operational responsibilities within a global, collaborative team.
- Willingness to work primarily from the Prague office in compliance with company policies, unless on PTO, work travel, or other approved leave.
