Senior Full Stack Engineer (f/m/d) - Berlin | Germany

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 PMs 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.

• →

  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 proactively identify and fix problems before they're reported.

• →

  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 Product Managers. 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, or excited to adopt them quickly.

• →

  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.

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.

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, and fellow engineers through regular 1:1s, operational reviews, and day-to-day collaboration.

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.

• Significant experience (typically 6+ years) building and owning production systems, with strong full-stack skills in JavaScript/TypeScript and deep backend expertise (ideally Node.js).

• Experience building user interfaces, ideally with React.

• Experience developing well-tested APIs (GraphQL and/or REST).

• Strong understanding of backend systems, scalability, and performance fundamentals.

• Solid knowledge of relational databases (especially PostgreSQL), including schema design and query optimization.

• Active use of AI-assisted development tools (Claude, Cursor, Codex, or similar) in your workflow, or a clear, demonstrated eagerness to adopt them.

• Ability to work with ambiguity: rough prototypes, evolving requirements, and imperfect information. You use judgment and experience to fill the gaps.

• Strong product sense. You think about why you're building something, not just how. You care about the customer experience, not just the code.

• Excellent communication and collaboration skills. You speak up when something's off, share credit when things go well, and give feedback with respect and clarity.

• A growth trajectory that shows steady improvement. You don't have to know everything, but you need to demonstrate that you learn fast and keep raising your own bar.
  

• Experience with on-call or operations (incident response, etc.), or openness to taking this on as we grow the team.

• Experience with GraphQL and Golang.

• Familiarity with cloud-native development (AWS, GCP).

• Knowledge of infrastructure as code tools (Pulumi, Terraform).

• Experience with monitoring and observability tooling (New Relic, Datadog, or similar).

• Experience working directly with customers or in customer-facing roles.

• Familiarity with headless CMS platforms or content infrastructure.

• Intro call with People Team

• Interview with the Hiring Manager

• Technical Interview

• C-Level Call and Reference Check (optional)

• Job Offer
