Senior Platform Engineer

About the role

We're looking for a Senior Platform Engineer to help us take our Internal Developer Platform and shared tooling to the next level. This role combines technical leadership with strong product thinking, working closely with engineering managers, technical leads, and engineers across teams to drive platform initiatives from idea to production.

What you'll do

• Lead platform initiatives from scratch to production, owning problem definition, technical design, implementation, rollout, and iteration.
• Build on top of our existing Internal Developer Platform (Backstage) by developing plugins, templates, workflows, and integrations that reduce cognitive load for product teams and other internal stakeholders.
• Actively engage with internal users, understand their needs, validate assumptions, and translate feedback into platform improvements.
• Design and maintain reusable tools, services, and abstractions that help teams deploy, operate, and scale their services safely.
• Make thoughtful architectural decisions and clearly articulate trade-offs among reliability, security, scalability, and developer experience.
• Partner with infrastructure and security teams to ensure platform capabilities align with operational and compliance requirements.
• Raise the bar for platform quality through documentation, standards, and mentoring.

What you'll need

• 5+ years of experience in software engineering, with a strong focus on platform, backend, or infrastructure-related work.
• Proven ability to lead technical initiatives independently and deliver production-grade systems with real users.
• Hands-on experience with Kubernetes and cloud-native architectures in a production environment.
• Practical experience with Internal Developer Platforms, developer tooling, or enabling infrastructure (Backstage experience is a strong plus).
• Solid understanding of CI/CD, GitOps concepts, and modern deployment workflows.
• Experience with cloud providers, preferably GCP, and infrastructure as code tools such as Terraform or Terragrunt.
• Strong product mindset: you're comfortable talking to users, prioritizing work based on impact, and iterating based on feedback.
• High ownership and autonomy: you take responsibility, make pragmatic decisions, and follow through.

What they offer

• 1,000 EUR annual learning budget, full LinkedIn Learning access, and free German language courses
• 30 days of annual leave, plus extra paid days for your birthday and moving day
• Home office setup budget and monthly home office allowance
• 20% company subsidy on pension contributions and subsidised BVG public transport ticket
• Mental health support with nilo.health and discounted Urban Sports Club membership
• Freedom to work from abroad for up to 90 days worldwide
