DEHN is a German company with over a century of history 😮. They were born creating protections for lightning and electrical surges, and over the years they have evolved towards hardware and software related to this same field. Their devices and software are responsible for preventing electrical surges and hazards ⚡.
It is an international company, with more than 2000 employees all over the world, and they have more than 20 offices in different countries, including Spain, where their subsidiary is DEHN Ibérica.
If you want to know the history of a company with more than a century of history, they have a very cool timeline on their website.
If you notice, one of their latest milestones on this timeline is the appointment of their CTO, Christian Höhler in 2020. Which shows the dimension that technology has in this stage of the company, where software is essential.
In addition, in 2021 the DEHN digital solutions GmbH came to life and their role is to support the digital transformation of DEHN. Their mission statement is “We enable DEHN to shape its leadership in the digital future”. They do this by showing & encouraging global collaboration without boundaries in an agile way. While f_ostering a data driven culture, a customer oriented mindset and automated processes_ and building great customer software, digital services and smart solutions.
They have hundreds of internal and external applications. From their own patented software that helps them measure thousands of environmental data, to electrical control software that saves lives, to their management applications. A company with such a history also has a very broad technological history.
The Spanish delegation has grown a lot in recent years, and it is also a strategic point for their logistics. That is why they have thought about establishing a technological operations center, a HUB, in Madrid. They have started with some operations personnel, but their intention is to create a team of 30-40 people in the coming years.
They are having problems stabilizing the infrastructure due to the accelerated growth of recent years, in addition to wanting to create new software that replaces old applications and helps them automate many actions.
The main challenge is to join and contribute to a high-impact team from the ground up, working in a complex IoT software environment that combines cutting-edge technologies with diverse use cases. Your mission as an IoT FullStack Engineer will be to design, develop, and maintain solutions that empower Dehn's mission of protecting and saving lives. You'll navigate a cloud ecosystem using technologies like Vue.js, Tailwind, Typescript, NestJS, MQTT Protocol, and TimescaleDB, among others.
You'll work closely with other Fullstack, Frontend, and Backend developers to build and refine tools that align with Dehn's ambitious 7-year technology strategy.
Dehn's roadmap includes evaluating and modernizing their software ecosystem, which comprises a diverse array of applications developed over the years. You will play a pivotal role in this transformation by:
- Assessing and standardizing the applications, identifying those that need refactoring or a complete overhaul.
- Helping to establish best practices in development and architecture, particularly for IoT-related solutions.
Additionally, you'll collaborate with the Germany-based team to stabilize and optimize the cloud infrastructure, due to their aims is to work entirely with AWS. Your focus will include automation, preventing downtime, and integrating IoT-specific protocols like MQTT. This will enable Dehn to deliver reliable, high-performance solutions in a rapidly evolving industry.
This role offers a unique opportunity to leave your mark on the foundation of a growing engineering team while contributing to impactful and innovative IoT solutions. Are you ready to take on the challenge? 🌍🌩️

Tus responsabilidades
IoT Solution Design and Development: Analyze, design, and implement scalable IoT solutions by integrating frontend technologies like Vue.js and Tailwind with backend frameworks such as NestJS and protocols like MQTT to ensure seamless functionality and performance.
Cloud-Based Development and Deployment: Develop and maintain cloud-native applications using AWS services, managing infrastructure with tools like Terraform, and ensuring high availability and robust deployment pipelines.
IoT Protocol Integration: Work with IoT-specific protocols like MQTT and databases like TimescaleDB to build reliable, data-driven applications tailored to real-time IoT environments.
API Development and Optimization: Design and implement secure, efficient APIs using TypeScript and NestJS, focusing on clean architecture and compatibility with IoT devices.
System Testing and Quality Assurance: Collaborate with the team to ensure end-to-end system functionality through thorough testing, debugging, and performance monitoring in cloud-based and IoT environments.
Cross-Team Collaboration: Work closely with Product Owners, DevOps engineers, and developers across Spain and Germany to align development goals, ensure smooth delivery, and maintain the highest quality standards.
¿Cómo lo harás?
Currently, the Software Team (where you will be integrated) is experiencing rapid growth. Although DEHN was founded over a century ago, it is now establishing the Spain Hub as a key part of its digital transformation strategy. The goal is to build a European reference team alongside their other hub in Germany. While the engineering teams in Spain are in an exciting growth phase, you’ll work closely with international colleagues across global technology teams.
There’s a lot to be done, as DEHN has developed numerous applications and solutions over the years. Now is the time to standardize, optimize, and streamline these efforts while collectively defining the best technological path forward. The backend primarily uses TypeScript, NestJS, and IoT protocols like MQTT, while also integrating cloud services like AWS. You’ll also collaborate with frontend colleagues who work with Vue.js, Tailwind CSS, and TypeScript, contributing to the fullstack ecosystem.
The team values small, autonomous groups that promote agility, self-management, and good practices. This approach allows for flexibility and continuous improvement while maintaining a strong sense of collaboration and shared purpose. DEHN, as a multinational company, offers the stability and financial security of a long-established organization. However, their technology teams operate with the agility and spirit of a startup, giving you the best of both worlds: stability and innovation.
This is your chance to help define and shape a growing engineering team, contributing to a robust IoT ecosystem while collaborating with top professionals in Spain and Germany. 🌍🌟
¿Cuándo trabajarás?
The work schedule offers flexibility, and you will have the responsibility of making decisions in this regard. The engineering team operates with a self-organized working day, as they strongly believe it promotes asynchronous and autonomous work, which is particularly beneficial considering the team's anticipated growth in the short to medium term. Get ready to soar to new heights! 🛫.

You have the flexibility to work from wherever you prefer, especially if you have a subscription to an airline that Dehn is already partnered with. Currently, the technical team primarily operates in a fully remote setup 🌴, but you also have the option to work from the office in Madrid whenever you choose.
Dehn initially started as a fully remote company, and while they want their tech team to be based in Spain, they strongly value the benefits of remote work and work-life balance. This means that you may have colleagues located in various cities such as Madrid, Salamanca, Valencia, or Majorca :)
Additionally, Dehn plans to organize periodic in-person meetings at selected locations, providing opportunities for face-to-face interactions. These gatherings aim to complement the virtual work environment and have already proven to be highly successful during their first occurrence.
The first of these meetings was a great success!
