About PortaOne

PortaOne is an international IT company: software vendor for telecom operators. We help telcos provide communication services even where it was impossible or unreasonably expensive until now. Throughout 20 years in the business, we have created a great product for communication service providers – an open-source and open architecture platform to run business operations (BSS: Business Support System), enabling any type of telecom business. It offers a unique combination of the virtues of commercial software (high-quality support, detailed documentation, etc.) and open-source style (access to the source code, tools to support changes created by the client, etc.).

Our solution has been adopted by more than 500 telco operators in 100+ countries on all five continents. The company was founded in 2001, and now we have more than 250 people in our staff. Demand for our products has been growing for more than two decades, and the pandemic has only intensified that demand. Now, it is time to take it to the next level. We have the technology and the team to beat most of the incumbent BSS telecom suppliers and sell to large international operators. We need a skilled copywriter/content designer to lead our activities to deliver the benefits of our product to our customers!

So, if you are looking for an interesting job that includes working for a company with our own in-demand product, opportunities for professional development, and a stable income – if you do not want a life of waiting longingly for the weekend, and instead to come to work with sincere joy – PortaOne is the right place!
