At VeiligWerk, safety comes first. Our mission is to help construction companies prevent accidents and protect their people. With our software, workers can easily report incidents and unsafe situations, organize toolbox meetings, run inspections, and more. Today, over 200,000 construction professionals across the Netherlands rely on our platform, with clients including Heijmans, Dura Vermeer, Boskalis, and TBI.
We’re a dedicated team of 15 in Weesp. As part of Pro4all, we combine our focus on safety with the strength of shared integrations. After a full frontend rebuild, we’re now working on backend‑heavy features and are looking for someone to take ownership of our backend and help us build an even safer industry.

- Architect & Design: Lead technical direction, design and improve schemas, queries, indexing, and data models and ensure performance, security, and reliability.
- Build & Integrate: Develop APIs for our frontend and implement key integrations with the Pro4all ecosystem (e.g., shared logins/SSO).
- Collaborate: Work closely with the other developers in Weesp to create awesome new features that prevent accidents on the construction site.
Our stack
- Backend: Node.js, RPC‑style microservices, MariaDB

About Us20 years ago at Pro4all, we embarked on a challenging mission: to digitise construction. Why? Because we saw that, despite all good intentions, costly mistakes were being made and materials unnecessarily wasted. Thanks to our software, construction companies can now work together more efficiently, build more sustainably and possibly even contribute to solving the housing shortage. Our products are used daily by tens of thousands of professionals working in the construction industry. But note that we are not just another software company. We are a team of passionate tech enthusiasts with years of experience. We believe digitalisation is the key to our customers' success. We want to move the (often conservative) construction industry and show that building can be easier (and more fun). xgiwjmb Our solutions have contributed to the largest (and smallest) projects in the Netherlands and abroad such as: Amare, Coolblue and Schiphol Airport.
