Senior DevOps / Platform Engineer (f/m/x)

MAIA is the AI platform built for industrial companies - 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 goal is to become the leading AI knowledge management platform for industrial companies in Europe - built for the companies that shape the physical world. Our team consists of structured organizational talents, creative minds, and technology-enthusiastic engineers, all with several years of experience in B2B SaaS and AI. 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. Tasks This is a senior individual contributor role with full ownership .

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. Requirements Technical requirements Strong experience running production systems in a SaaS environment.

Ways of working 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.

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. If this role sounds like the right next step for you, we would love to hear from you.
