Backend Developer

Permanent employee, Full or part-time · Weesp, Hybrid

Your mission

VeiligWerk builds software that helps construction companies prevent accidents by making it easy to report incidents and unsafe situations, plan toolbox meetings, run inspections, analyze trends and a whole lot more. We currently serve 200,000+ construction workers across the Netherlands, with clients like Heijmans, Dura Vermeer, Boskalis, and TBI. We were recently acquired by Pro4all, but will continue to run our own product with a few shared integrations.

We’re a close, on-site team of 14 in Weesp. After a major frontend rebuild, we are working on new features that are more backend-heavy and we’re looking for someone to become the goto owner of our backend.

What you’ll do

Own and evolve our backend platform: Node.js services (RPC-style) backed by MariaDB.
Design and improve schemas, queries, indexing, and data models for performance and reliability.
Build and maintain APIs powering the frontend.
Lead backend technical direction: architecture, standards, code quality, observability, and security.
Implement and maintain integrations with the Pro4all ecosystem (e.g., shared logins/SSO).
Collaborate closely with the frontenders in the team to create awesome new features.

Our stack

Backend: Node.js, RPC-style microservices, MariaDB.
Currently on bare-metal Linux, migrating toward Kubernetes.
Frontend: React (TypeScript), Bootstrap, Redux.

Your profile

What we’re looking for

Experience with Node.js.
Experience with MariaDB/MySQL at scale.
Experience designing and operating service-oriented systems with clear boundaries.
Security-minded: authentication/authorization, secure-by-default practices, data privacy (GDPR).
Practical operations know-how on Linux.
Clear communicator who enjoys being on-site and collaborating in a tight-knit team.
Professional proficiency in English; Dutch is a plus.

Why us?

Become “the master” of the backend with real ownership and high impact.
Mission with purpose: help reduce accidents in construction.
Friendly, low-ego, on-site culture in Weesp with fast feedback loops.

About us

20 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). Our solutions have contributed to the largest (and smallest) projects in the Netherlands and abroad such as: Amare, Coolblue and Schiphol Airport.
