Software Engineering Internship

Are you looking for an internship that will let you do much more than just code according to some external requirements? At 1oT, you'll have the opportunity to gain professional skills and build your resume.

As an engineering intern, you’ll be able to help with improving our platform by building kick-ass new features and optimizing for the best solutions. Since we’re building our own product, you get to pitch in on which technologies to use, what approaches to take, and ultimately assume ownership for specific parts of the product! The IoT sector is considered to be one of the fastest-growing in the world, so why not to find out how this field works?

You will receive support and first-hand know-how from our 1oTeam of troopers. We come from different cultural backgrounds and have varied skill-sets, so life never gets boring. What connects us is our #nobullshit attitude, giving and expecting honest feedback, and a good sense of humor.

Additional information

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 gives our customers an option to 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 e-scooter sharing, fleet management, or smart city companies, just to name a few. As these companies are operating in many different countries, they don’t want to deal with different telecoms and SIM cards every time they enter a new market, and this is where 1oT offers them a helping hand with the eSIM.

Today, 1oT's connectivity services are used in more than 1 million IoT devices deployed in more than 130 countries in the world.

Additional requirements

  • Ability to work on-site either in Tallinn or Tartu.
  • Eligibility to work full-time for the full 3-month period.
  • Legally allowed to work in Estonia (if not an Estonian citizen).
  • Portfolio or GitHub link is strongly recommended.
