Senior Full-Stack Engineer (m/w/d)

Stellenbeschreibung:

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

As our first Engineer, you wear every hat. You are the Architect, the DevOps team, and the Senior Developer rolled into one.

Play an active role in making key decisions on the application architecture and the way the product delivers its benefits.
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 and evolve both our backend infrastructure and frontend design system, ensuring consistency, scalability, and developer velocity
As the first hire, you set the bar for code quality. You will implement testing strategies and coding standards that will guide future hires.
You are a partner to the business. You translate business goals into technical requirements, prioritizing features that deliver value to customers immediately.

Requirements

5+ years of Full-Stack experience. You have seen enough production fires to know how to prevent them. You don't need a manager to tell you what to do next.
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.
