• Configure a complete CI/CD pipeline from scratch and continuously improve it • Use automated deployment tools like Gitlab or Jenkins • Implement automated end-to-end testing frameworks • Manage deployment and resources in the AWS ecosystem • Administer Linux systems and utilize scripting languages for process automation

**Position Description:** This position focuses on creating and modifying pipelines using GitHub Enterprise Cloud repositories. The role requires expertise in developing and maintaining pipelines using Jenkins servers and troubleshooting deployment issues. Candidates should incorporate metrics such as Mean Time To Build (MTTB) and Mean Time To Deploy (MTTD). Experience with multiple CI/CD tools, Git Actions, and code scanning tools like CodeQL, Fortify, SonarQube, and Nexus is desired. Familiarity with automation tools such as Selenium, Cucumber, Maven, and AWS CodeBuild/CodeDeploy is advantageous.

Role Description We are looking for an experienced professional to join our team as our first dedicated Senior DevOps / Platform Engineer (f/m/x) - someone who will own this area end-to-end and build the foundation for everything that follows. This is a senior individual contributor role with full ownership. Your mission is to make MAIA's platform reliable, secure, auditable, and developer-friendly, at a stage where every decision you make has lasting impact. - You take full ownership of our infrastructure - Hetzner first, AWS, GCP, and Azure for selected services. - You own our CI/CD pipelines (GitHub Actions) and deployment workflows, continuously improving rollout strategies, versioning, and rollback procedures. - You build, improve and maintain our observability stack (Grafana, Loki, Sentry, Posthog) - metrics, logs, traces, and alerting that surfaces problems before customers do. - You implement and improve our security fundamentals: IAM, secrets management, TLS, vulnerability scanning, and patch management. - You implement the technical controls required for our ISO 27001 certification and ensure evidence is continuously and auditably produced. Qualifications - Strong experience running production systems in a SaaS environment. - Solid understanding of Linux systems and networking fundamentals, containers and reverse proxies and API gateways (e.g., Traefik, Kong). - Strong security fundamentals: IAM and least privilege, secrets management, vulnerability scanning, and patching. - Proven experience with Infrastructure as Code (Terraform or equivalent), CI/CD pipelines (GitHub Actions or similar), and observability tooling (Grafana/Loki or similar). - PostgreSQL operations basics: availability, backup and restore, performance awareness. - Fluent in English. German is a plus. Requirements - Strong ownership mentality - you take responsibility end-to-end, without needing to be managed. - People enjoy working with you - not just because of what you know, but because of how you interact with them. - Pragmatic builder - you improve systems without adding unnecessary complexity, and you can defend why a simpler approach was the right call. - AI is part of how you work - not just as a tool you use, but something you actively explore. You experiment with models, prompts, and workflows, and you have opinions about what actually works. - You prioritize based on risk and business impact, not technical interest alone. - Comfortable working in a fast-moving startup environment with ambiguity and shifting priorities. - You communicate clearly with both technical and non-technical stakeholders. Nice to have - Experience with ISO 27001 implementation, especially technical controls. - Experience with NixOS. - Experience with self-hosted Supabase and Postgres-based platforms. - Experience with SRE practices: SLOs, error budgets, and incident review culture. - Familiarity with multi-cloud usage patterns (Hetzner, AWS, Azure, GCP). Benefits - The opportunity to build and own an entire platform engineering discipline from the ground up at a well-funded, fast-growing startup. - Short decision-making paths, real ownership, and a team that trusts you to lead your area. - Direct impact on product reliability, security posture, and company growth. - Flexible working hours and fully remote. - Access to a WellPass fitness membership for your physical and mental wellbeing. - Competitive salary of 70,000 - 80,000 EUR and VSOP (Virtual Stock Option Plan) participation opportunities. - We are a remote-first company and have been since day one. Most of our team is based in Leipzig, but remote team members are a natural part of how we work - not an exception. - We do bring the full team together in Leipzig, or somewhere else, a few times a year for team events and planning sessions, with all travel and accommodation costs covered. - If you are somewhere in Germany you are in scope. Hiring timeline - We are aiming to have this role filled by May 2026. - The process consists of three stages: an intro call (30min), a technical interview (90min) and a final conversation with leadership. - We move quickly and will keep you informed at every step. Company Description We are driven by our passion for innovation! MAIA is the AI platform built for industrial companies - the places where generic AI tools break down because the data is complex, the stakes are high, and precision actually matters. We focus on the hard problems: integrating with real engineering workflows, understanding complex technical documents, and turning implicit organizational knowledge into something the whole company can build on. Our team brings together sharp organizational thinkers, creative problem solvers, and engineers who care deeply about what they build.
