Job description

The mission

As a Full Stack Engineer, you will contribute to the design and development of state-of-the-art applications serving thousands of internal and external users. You will work with modern architectural patterns-micro-frontends, Web Components, event-driven systems-and help evolve a rapidly growing platform.

You will be part of an Agile environment that encourages experimentation, continuous improvement, and strong collaboration with Product, UX, and Architecture teams.

A core part of your mission will involve our BPM renderer, a critical component of the business process management ecosystem. The renderer interprets and executes business workflows created in our BPM design tool, dynamically transforming process definitions into interactive, user‑friendly UIs. You will help expand its capabilities, improve performance, ensure compatibility with new standards, and contribute to a future‑proof architecture.

Your work will include:

• Rewriting and modernizing existing modules using Web Components, Redux, Redux Saga, and TypeScript.

• Building new application features for internal and client-facing platforms.

• Improving platform performance, stability, and long-term maintainability.

• Creating and maintaining shared libraries and reusable Web Components.

Your Day to Day

• Develop and maintain high-quality software following clean code principles and internal coding standards.

• Estimate implementation effort and testing timelines with accuracy and responsibility.

• Collaborate closely with Product Owners, UX Designers, and Architects to shape product and technical specifications.

• Ensure maintainability, documentation, test coverage, performance optimization, and resilience.

• Build reusable, scalable Web Components and frontend modules used across multiple applications.

• Work with QA to ensure adequate test automation coverage.

• Actively contribute to Agile ceremonies (planning, refinement, daily stand-ups, retrospectives).

• Support and mentor team members when needed and collaborate across chapters to share knowledge.

Swicon Stories

Real people. Real challenges. Real impact.

„The whole hiring process was a really positive experience for me. I was given the opportunity to move forward professionally and to test myself in a new, more senior role. I was trusted from the start, and I had all the support I needed to take the next step in my career with confidence. They connected me with the right technical contact, and every question I had was answered quickly and clearly, so I never felt left on my own. Communication was smooth, each step built on the one before, and the whole process moved surprisingly fast and without a hitch.”

K. R. – Solution Architect

“Looking back over more than 15 years, Swicon gets top marks from me: it has built itself into a fast-growing multinational, and all the while it has backed its people professionally across the board — it even supported my PMP certification with a proper training course.”

B. T. – Sr. Projectmanager

“I’ve been working with SWICON for almost a year and a half now, and it’s been a positive experience from start to finish. Both the hiring process and the admin side of things ran smoothly, and whenever I had a question, help came quickly. I particularly appreciate how kind and helpful my colleagues are, and the fact that the company genuinely invests in building a community — there are regular programmes and events.
I’ve grown a lot professionally in my time here, too. My tasks and my responsibilities have kept widening, I’ve been able to take on more complex challenges, and I’ve also had the chance to support and mentor others. On the IT side I’ve been given opportunities that made a real difference to where I am professionally, so on the whole I see SWICON as a supportive place that gives you genuine room to grow.”
