Senior Fullstack Engineer (f/m/d) - Berlin I Germany | EU I Remote

How will you make an impact? As a Senior Full Stack Engineer, you'll work at the intersection of engineering and product to shape how our users build with Hygraph. You'll ship features that solve real customer problems, contribute to our CMS core, extend our platform capabilities, and help bring AI-powered features to life. You won't wait for perfect specs or pixel-perfect designs. You'll use your judgment, collaborate closely with product managers, designers, and customers, and move fast using modern AI-assisted development tools. This role is for someone who sees engineering as a team sport, takes ownership without waiting for permission, and thrives in an environment where initiative matters more than instructions. What you will be working on: Core CMS development: Evolve the GraphQL-native CMS powering enterprise teams worldwide, improving performance, reliability, and developer experience. CMS extensions and integrations: Develop and maintain extensions that expand what customers can do with Hygraph. AI-powered features: Contribute to our AI roadmap by building intelligent capabilities into the product. Customer-facing improvements: Use monitoring data, customer feedback, and your product instinct to identify and fix problems before they're reported proactively. Some of your tasks and responsibilities: Collaborate in a cross-functional, autonomous team to deliver features and continuous improvements, often working from rough prototypes or early concepts rather than polished designs. Translate business needs into technical solutions by working closely with the Product team. Occasionally, participate in customer conversations to validate that what you're building actually solves their problems. Comfortable using modern AI-assisted development tools (Cursor, Claude, Codex, or similar) to accelerate development. Proactively identify issues through monitoring and observability data. Then fix them, don't just flag them. Contribute to architectural decisions that keep our platform scalable, reliable, and maintainable. Share what you know, learn from others, and help your teammates grow. Engineering here is collaborative. We win together. Expectations timeline 1 Month You'll complete onboarding covering our product, tech stack, infrastructure, and vision. You'll meet people across the company, get familiar with our codebase, and ship your first contributions. You'll start building context on how our customers use Hygraph and what matters most to them. 3 Months You'll be delivering features and improvements to production with confidence. You'll have a solid understanding of Hygraph's product and architecture, and you'll be contributing ideas, not just code. You'll have built working relationships with your team lead, PMs, designers, and fellow engineers through regular 1:1s, operational reviews, and day-to-day collaboration. 6 Months By now, you'll be making significant contributions to both the product and the team. You'll bring fresh perspectives from your experience and help raise the bar across performance, architecture, and how we work. You'll be someone the team relies on. Not because you do everything, but because you make everyone around you better.
