For the last ten years, the Twilio Super Network group has been hard at work building an Intelligent and Resilient Global Infrastructure to reach anyone in the world over SMS or a voice call through one provider, at any scale. There are hundreds of millions of messages and calls going through the Super Network platform and the telecom carriers connected to it. These transactions are Twilio’s major source of revenue and its biggest expense. Our team builds and maintains carrier cost tracking systems that help Super Network control and optimize these expenditures.

To be able to process and enrich this enormous amount of complex business data in a scalable, flexible, and resilient way and achieve the most accurate outcome, we use Spark as the our core distributed computing engine, Kafka as the asynchronous data pipeline and combine multiple data sources depending on our need - MySQL, ElasticSearch, S3, and Presto.

Most of us were Java developers prior to joining Twilio, but have quickly transitioned to our now preferred language, Scala.We are the first and so far the only Twilio engineering team outside of the US to receive an Iron Owl - Twilio’s internal award for reaching the highest bar of operational and engineering excellence for a service. Also, we’re not afraid to crack a joke or two once in a while.

To sum it all up, if you choose to join our team you’ll get a unique chance to work and learn from the best engineers in an environment that is as challenging as it is friendly and comfortable.

Twilio is truly outstanding; we are a company committed to your growth, your learning, your development, and your entire employee experience. We only win when our employees succeed, and we're dedicated to helping you develop your strengths. We invest in weeks dedicated to tackling hard problems and crafting your own ideas. We have a cultural foundation built on diversity, inclusion, belonging and innovation, and we want you and your ideas to thrive at Twilio. Come join us.


This position will be located in our beautiful and well-designed office at Veerenni 38 in Tallinn, though considering the world’s current circumstances will start as remote.

Around the world, Twilio offers great benefits and perks to support the physical, financial, and emotional well being of you and your loved ones. No matter where you are based, you will experience a company that believes in small teams for maximum impact; seeks well-rounded talent to ensure a full perspective on our customers’ experience, understands that this is a marathon, not a sprint; that continuously and purposefully builds an inclusive culture that empowers everyone to do their best work and be the best version of themselves.
