💻 Senior Fullstack Developer – Migration to Web Platform

Location: Kontich / Hybrid
Department: Engineering
Reports to: CTO
Type: Full-time

🌟 The Mission

We’re reinventing our core platform — migrating our legacy client-based application into a modern, web-first ecosystem that’s built for speed, scalability, and a world-class user experience.

We’re looking for a Senior Fullstack Developer who’s excited to build the future — someone who can balance strong technical craftsmanship with architectural thinking, and who’s eager to shape the core foundation of our next-generation web product.

You’ll be at the heart of the transformation — designing, developing, and delivering code that moves the mission forward every day.

🎯 What You’ll Do

• Design and build core features of our new web platform from the ground up.

• Collaborate with backend, frontend, DevOps, and QA teams to deliver seamless migration of features and data.

• Translate complex business logic from the client application into clean, efficient, scalable web architecture.

• Work with product managers and UX designers to create elegant, intuitive interfaces.

• Contribute to technical architecture discussions, and help define standards, tools, and frameworks.

• Ensure code quality, performance, and security across the stack.

• Mentor junior developers and contribute to a culture of technical excellence.

• Experiment, optimize, and continuously push for improvement in both product and process.

🧩 What You Bring

• 5+ years of experience in fullstack software development.

• Deep proficiency with modern JavaScript frameworks (React, Vue, or Angular) and backend technologies (.NET & Node.js).

• Experience in API design, microservices, and REST/GraphQL architectures.

• Solid understanding of cloud environments (AWS, Azure, or GCP) and DevOps practices (CI/CD, containers, etc.).

• A strong sense of ownership, attention to detail, and pride in building high-performing systems.

• Excellent collaboration skills — able to work closely with designers, PMs, and fellow engineers.

Bonus Superpowers

• Experience in migration projects or legacy modernization.

• Background in data modeling and database optimization (SQL/NoSQL).

• Familiarity with TypeScript.

• Interest in performance optimization and front-end architecture.

• You’ve built something end-to-end — from prototype to production.

💡 Why Join Us

You’ll be joining a mission-driven engineering team that’s building the future of our platform — not just maintaining it.

This is your chance to work on a high-impact, high-visibility project that redefines how thousands of users interact with our products. You’ll have the autonomy to make key technical decisions and the support of a leadership team that values innovation, quality, and craftsmanship.

We offer:

• Competitive salary + performance-based salary increases

• Flexible remote or hybrid work

• A culture of trust, growth, and creativity

• The chance to shape the future architecture of a company-defining product
