Cloud Software Engineer

  • Louvain-la-Neuve, Belgium
  • Junior to senior
  • R&D


What you’ll do

As a backend engineer, you will contribute to our Multipath TCP proxy software that runs in the operator network or in the cloud. Your code will handle dozens of Gbps and run 24/24. You will have many interactions with backbone engineers and handle all requirements for a telco-grade solution (e.g. logging, redundancy, robustness, security, etc.). End users will rely on your code for ensuring their Internet access availability and improved capacity.

In that mission, Tessares will help you with the following assets :

  • The team: As part of the backend development team, you will partipate in a continuous feedback loop (e.g. through peer reviewing).
  • The experience: You will work in close interaction with major contributors to the Multipath TCP protocol and implementation.
  • Powerful servers: You will have access to high-end servers, designed to support line-rate forwarding. But will your code be able to sustain such a volume of traffic ?
  • Yourself: As a recent start-up, we will be eager to receive input from you and strive to reach ever more ambitious objectives. Together.

Useful knowledge you have

We all need to be fluent in English, both written and spoken. For backend software development, we currently use the C programming language and closely interact with the Linux kernel. As backend engineer, you will also closely interact with engineers from telco operators in order to integrate the solution within their network. Given your very network-oriented role, it would be good that you master TCP/IP protocols. Experience in an operator environment would be a plus (network management & monitoring, load balancing, redundancy and scaling of network services, network security & pen testing, etc.).

Do you feel Tessares compatible ?

In a start up, it is important that the team has cohesion, with each collaborator nicely complementing others, while still sharing Company values. We also decided to adopt an agile framework (with continuous integration, automated testing, peer reviews). You will have frequent interactions with other specialists, and will enjoy varied activities. Our customers will be in Europe and outside of Europe, you will have the opportunity to meet them to better understand their needs. You won’t be strictly confined into your role, and will have the opportunity to move within the company as it grows and your interests evolve.


In addition to providing a motivating working environment, we offer an attractive salary package in accordance with your seniority level.

After some time with us, you may even receive stock options, so that you can get your share of Tessares success !
