1oT is aggregating many telecoms around the world into one eSIM and connectivity management platform to provide global connectivity to IoT devices. Our two software elements, the eSIM infrastructure and connectivity management platform, have been developed in-house and have stood out in the market. With the certified eSIM infrastructure (1oT eSIM Core), our customers can swap telecoms whenever they wish, and with the connectivity management platform (1oT Terminal), they can control and manage connectivity on a self-service basis either through our UI or APIs.

Our 2G, 3G, 4G, NB-IoT, and LTE-M connectivity service is used by 400 customers in 173 countries. But we won’t stop here. We are now on a mission to build our own packet gateway—a secure interface between mobile networks and external packet data networks, including the Internet, private corporate networks, and other IP-based services.

To achieve this goal, we are looking to bring on board a new team member who possesses:

• Experience in network architecture
• Mid-to-senior level expertise in C/C++ and SQL
• A strong desire and ambition to build innovative solutions from the ground up
• Problem-solving & get-things-done attitude (no place for corporate mindset).

What you’ll do:

• Incorporate technologies like:
  • VPP (vector packet processing) as networking core
  • RabbitMQ for listening to configuration changes
  • SQL and Redis for state management
• Help us build a state-of-the-art system for managing the internet connection of hundreds of thousands of IoT devices
• Work with other developers and system administrators to integrate the system with existing services and a larger cloud architecture.

We will offer:

• Meaningful work with global impact – our SIMs are used to track endangered species, safely deliver vaccines, and provide electricity to off-grid households
• Personal growth opportunities in a company with a proven track record and a sustainable financial model
• Crazy and ambitious international team with a no-bullshit attitude, eager to learn and get stuff done
• A supportive, collaborative, and flexible work environment.
