Senior SW Developer at the Erlang/OTP team
The Erlang/OTP team consists today of 16 developers.
We are developing Erlang/OTP, a development and runtime environment for Erlang which supports efficient development of reliable, concurrent highly scalable control systems.

Erlang/OTP is used in several Ericsson products such as:
• Radio Base Station (multi standard including 5G)
• SGSN/MME (mobile packet data for 2G, 3G, 4G and 5G).
• SBG Session Border Gateway (an IMS node)
• ... many more uses
 
As Erlang/OTP is Open Source (with Ericsson as the main developer) it is also used with great success outside Ericsson.
Some well known and successful users of Erlang/OTP in their products or services are:
• Whatsapp (mobile messaging)
• Klarna (Payment solutions for Web-shops)
• Bet365 (on-line betting)
• ... and there are many more

 

Erlang/OTP is based on the programming language Erlang and can be run on a number of operating systems such as Linux, Windows, Solaris, Mac OSx , FreeBSD etc.
Erlang is developed by Ericsson and is a functional programming language very well suited for robust systems with many parallel communicating processes, which is typical for telecom applications and control systems in general.
The built in support for concurrency and multi-core scalability is well acknowledged and used as inspiration for other languages and frameworks.

 

The development within the Erlang/OTP team is done in small teams with fast decisions and minimal administrative overhead.
All developers take part in the complete development chain from system work, implementation, documentation, integration and test. The small teams establish a creative environment where own initiatives are encouraged.
We are using GIT for the development with Linux as the main platform to support.
In addition to Erlang we also use quite a lot of C and a small amount of other languages.
