Think of 1oT as a Tinder of telecoms. We're transforming the IoT industry with one dynamic connectivity service offering by combining different telecom profiles on a single eSIM card. This lets our customers choose the best option for their particular use case or location. Our customers are IoT and M2M device manufacturers or service providers operating on a global scale, such as micromobility, fleet management, or smart city companies.

We are looking for a senior fullstack Software Engineer

As a senior engineer, you will be a crucial member of our eSIM team, responsible for developing a unified eSIM platform for the automotive industry on top of our existing eSIM infrastructure. The platform will enable car manufacturers and operators to remotely manage different mobile network connections by mobile operators, handle various service providers' SIMs and eSIMs, and implement different eSIM technologies in their smart devices, all from one cloud-based service.

What you'll do:

• develop scalable and secure services on Java / Spring Boot / SQL and sometimes on TypeScript / Vue.js
• build internal integrations between multiple services via REST APIs or messaging queues
• develop APIs that our customers integrate with
• design new value-added tools and capabilities to our system to differentiate us from the competition
• help with advancing the technical architecture of the platform
• help define, manage, and configure Docker-based systems (Linux).

What you'll bring:

• at least 6 years of professional Java experience
• a desire and hunger to build something from scratch
• problem-solving & get-shit-done attitude (no place for corporate mindset)
• interest in working with backend frameworks
• experience with building and working with different APIs
• excellent teamwork and self-management skills – micromanagement is not in our DNA)

• experience related to telecommunications or security development and implementation will come as a huge bonus

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
• the opportunity to have a say in how things operate – your voice is important
• personal growth opportunities in an established startup with a proven track record and a long list of paying clients (our eSIMs are used in 173 countries)
• a crazy and ambitious international team with a no-bullshit attitude – we're eager to learn and get stuff done.
