• 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.

• Working towards improving the system's non-functional qualities, including availability, scalability, security, and durability. • Engaging in Scrum-based work management by participating in team meetings and discussions. • Creating automation and process improvements. • Supporting and developing new tools used by our Engineering department. • Monitor systems and create infrastructure documentation. • Participating in planning and taking full ownership of our initiatives. • Working with our tech stack, including GCP - GKE, Cloud SQL, Memorystore Redis, GCS, VMs, Cloud Run, PSC, Artifacts Registry, Secret Manager, CDN, K8S and Helm, Argo CD and Argo Workflows, Pulumi, Istio, Grafana stack, Gitlab.

• Design, configure, and maintain CI/CD pipelines and production/testing environments using Ansible and other automation tools. • Implement and manage modern DevOps tools across the entire lifecycle, from infrastructure provisioning to service monitoring. • Develop automated backup systems and ensure robust infrastructure security protocols are in place. • Engage in direct, independent communication with the Customer’s DevOps team to align on architectural goals and ensure seamless delivery. • Support and optimise containerised environments to handle the demands of a major financial platform.
