The Work Environment


Integration and interfacing

Our core activity is safety and security applications. We're bringing the latest web technologies to real-world hardware i.e. we don't work in the cloud. We interface with very diverse equipment: radar, sonar, thermal imaging, drones, software-defined radios and more. Our UI runs on touchscreen displays, tablets, phones, smart-glasses...


Challenges

If you are looking for an easy job, this isn't it. We operate in mission critical environments. Our systems can operate at sea and high security areas with limited connectivity to the data center. So, all your assumptions about cloud development techniques and operating environments will be constantly challenged. Timelines are strict, and creativity is often required to solve unexpected technical issues. It can be extremely diverse, interesting, and rewarding if you are up to the challenge!
