Jobbeschreibung

Centify is a fully bootstrapped, early-stage company. We are profitable, independent, and building a product that drives real business value. At Centify, we are on a mission to revolutionize the way sales teams manage and shape their commissions models.

You will be the accelerator. We are looking for a Senior Full-Stack Engineer to double our engineering capacity. Working 1-on-1 with the CTO, Tim, you will dive immediately into high-priority feature development and architectural improvements. This is a role for a developer who wants high impact, close collaboration, and the chance to define the engineering culture of a growing team.

Tasks

• You own the full lifecycle of new features. From database modeling (SQL) to the API logic (Node.js) and the UI implementation (React).
• Contribute to both our backend infrastructure and frontend design system, ensuring consistency, scalability, and developer velocity
• Translate product ideas into production-grade UI using modern frontend frameworks and component libraries
• Play an active role in making key decisions on the application architecture and the way the product delivers its benefits.

Requirements

• 5+ years of Full-Stack experience. You have seen enough production fires to know how to prevent them.
• Deep expertise in TypeScript, React, Tailwind CSS and proven ability to deliver high-quality features across both frontend and backend
• Experience designing and implementing APIs (REST, GraphQL, or gRPC) and integrating them seamlessly into polished user interfaces
• You enjoy pair programming, code reviews, and technical debates. You are ready to challenge the CTO’s ideas and have yours challenged.
• You know when to build a "quick and dirty" MVP to test a hypothesis and when to engineer a robust solution for the long term.
• You thrive in an early-stage environment where requirements can evolve (fast).

Tech Stack

• Languages: TypeScript
• Backend: GCP, BullMQ, Redis, PostgreSQL
• Frontend: React, shadcn/ui, TailwindCSS

Benefits

• You aren't just a ticket-mover. You are the second half of the engineering team. Your fingerprints will be on every major release.
• We are bootstrapped. We don't chase VC hype cycles; we build a sustainable, profitable business on our own terms.
• Work directly with an experienced CTO, gaining insights into technical leadership and business strategy.
• As the team grows, you are positioned to lead.
• Competitive salary (70.000€ - 80.000€), modern hardware of your choice, and the flexibility of a results-driven culture.

Bonus Points

• Active contributions to open-source projects
• Deployed side/hobby projects that we can check out
• Actively engaged in sports or volunteering
• Experience in starting a company or working at a top-tier high-growth startup
