We want this to be the place where you do your best work.\nOur mission is to redefine identity for the global economy. We're backed by world-class investors including CapitalG and Index Ventures, as well as founders and executives from companies like Stripe, Adyen, Notion, Remote, Qonto, Framer, Anthropic, Mollie, OpenAI and Goldman Sachs.\nDuna's infrastructure is part of the product. Enterprise customers buy our reliability, security posture and auditability, not just our features.\nSince your role with us will rarely fit a job description, we only wrote a crisp overview.\nWHAT YOU'LL BE DOING IN THIS ROLE\nOwn and harden our platform: AWS, Kubernetes, Postgres, infrastructure as code, CI/CD, observability and incident response\n\nMake security the default, with least privilege, secrets management and tenant isolation built into the platform instead of bolted on later\n\nTurn our SOC 2 and ISO 27001 commitments into controls and evidence that are automated, not a yearly scramble\n\nTurn recurring operational toil into self-service systems that engineers actually adopt, from preview environments to internal access\n\nHelp Duna run AI agents in engineering safely, with the sandboxes, guardrails and human checkpoints that make it possible\n\nTake calm ownership of incidents, and make sure the system gets better afterwards, not just the moment\n\nWHAT WE'RE LOOKING FOR\nDeep, hands-on experience with AWS (or comparable), Kubernetes, infrastructure as code, CI/CD and observability\n\nReal security engineering skills: you turn least privilege and auditability requirements into working systems\n\nComfort with the enterprise IT side of a startup, from certifications and customer security reviews to identity and device management\n\nHigh agency in ambiguity, turning a vague problem into a shipped plan\n\nPragmatic judgement about when to harden, when to simplify and when to leave something alone\n\nCuriosity about what AI changes in how we build and run software\n\nOur platform runs on AWS and Kubernetes with Terraform, Postgres and RabbitMQ, alongside a Node.js and TypeScript product stack built on event sourcing. You will not have used all of it before. We care more about the depth you bring and how you pick up the rest.\nA final note before you apply: please read through our website in detail. You'll find the fundamentals there: what we believe in, how we work, and why we're building this company.\nWe're a remote-first, fast-moving team of builders looking for exceptional people who love to create, build, and ship. Beyond passion and grit, we highly value curiosity, authenticity and kindness.\nIf this sounds like you, we'd love to hear from you!\nPS. We are looking to hire passionate people from a variety of backgrounds. So even if you don't check all the boxes, we welcome your application!","description_format":"text","description_chars":2940,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Netherlands","iso":"NL","kind":"country"},{"name":"Amsterdam","iso":null,"kind":"city"},{"name":"Germany","iso":"DE","kind":"region"},{"name":"France","iso":"FR","kind":"region"},{"name":"United
