• Lead incident response, perform root cause analysis, and implement recovery and long-term fixes; • Manage infrastructure using Terraform, Terragrunt, and automation tools for consistency and repeatability; • Support vulnerability management; • Monitor resources, forecast growth, and implement scaling strategies; • Participate in 24/7 rotations for timely resolution of critical incidents;

• Design, implement, and automate components of large-scale distributed cloud systems. • Implement and support PAM solutions primarily on OpenStack, ensuring secure and reliable access management. • Build tools, automation, and workflows to improve availability, scalability, latency, and operational efficiency. • Work closely with engineering and delivery teams to deploy high-quality software in a fast-paced environment. • Monitor production and development environments and implement preventive and corrective measures to ensure platform reliability. • Participate in incident response, debugging, and root cause analysis for production issues. • Collaborate across teams to deliver consistent and reliable solutions aligned with. • Document designs, operational procedures, and troubleshooting guides clearly and effectively. • Contribute to improvements in reliability metrics such as availability, MTTD, and MTTR.

• Architect and scale our AWS infrastructure, including container orchestration, autoscaling, networking, and cost optimization • Build our observability and alerting platform from the ground up. You'll own it from design through production deployment • Lead infrastructure builds for compliance (SOC 2, HIPAA). We need someone who scopes, builds, and ships, not just advises • Harden container workloads and secrets management across production, staging, and isolated compliance environments • Own the shared infrastructure stack (Postgres, Redis, Celery). Find bottlenecks, fix them, and add capacity before they become incidents • Build and maintain CI/CD pipelines, optimizing for deploy speed, reliability, and security • Extend our Terraform codebase to keep environments reproducible and audit-ready. We ship IaC changes weekly, not quarterly • Define and own our reliability practices: SLOs, incident response, post-mortems, and the production tooling to back them up • Unblock engineering teams by reducing deploy friction, improving dev environments, and eliminating toil • Share on-call with a small team. When things break, you lead the response, run the post-mortem, and make sure the fix ships

• As a Senior NixOS / DevOps Engineer (m/f/d), you will support our clients in building modern, declarative, and highly automated software and infrastructure processes. • Consulting and implementation around Nix and NixOS: from architecture reviews and the design of modern system landscapes to the production rollout of declarative environments. • Analyze and optimize existing software architectures, source code, and development processes with a focus on quality, efficiency, and reproducibility. • Design, implement, and evolve CI/CD pipelines (e.g., GitLab, Nix Hydra), including automated build, test, and deployment pipelines. • Introduce and secure reproducible builds and modern build systems (e.g., CMake, Meson) in complex enterprise environments. • Build and maintain automated testing environments (unit, integration, and HIL tests) to ensure stable, test-driven development workflows. • Support developer and DevOps teams in adopting declarative, test- and quality-oriented working practices.
