Junior Fullstack (PHP/JS) developer

About Mixvoip

Mixvoip is a Luxembourg-based company providing cloud telephony, smart networking, and high-speed internet services.

We build and operate communication systems that businesses rely on every day. We develop our tools in-house, and that’s where you come in!

About the role

We are looking for a junior Fullstack (PHP/JS) developer to strengthen our team of exceptional coders. You will be working in a collaborative environment where everyone helps each other and no question is too much. You’ll be working to improve and extend our internal APIs that are used by our in-house CRM/ERP tool. There may also be other tools that will use these same APIs.

• Backend stack: In this role, you’ll be working with Symfony 7.4 using PHP 8.4. We use MySql/Maria databases which are connected through Doctrine (built-in with Symfony).

• Frontend stack: We use Quasar that is based on VueJs for out frontend.

• Version control: We use Gitlab to manage our repositories. It’s like Github, but private and self-hosted. Issues are handled with Notion.

• Environment: You’ll be using Linux as your OS as Windows complicates things performance-wise and you don’t need a Mac. Your IDE will be a company-licensed PhpStorm. You’ll be using Docker for setting up your environment, this saves time as you won’t have to install and configure any dependencies (web server, php, etc.). We use Claude Code for AI assisted development.

• Automation: We use Make to automate setting up a test/dev environment. You’ll also be writing code that will be run in a cron using Symfony commands. In case you’re wondering, cron is a job scheduler on unix systems which allows to automatically run scripts at a given time.

• Asynchronous code: We use RabbitMQ to run code asynchronously in certain cases. Some of the code we produce need a long time to finish. We queue them up to be run when resources are available, which avoids hanging scripts blocking the terminal.

• Testing & debugging: Our tests are written with PHPUnit 11.4. We use xdebug in case we need to debug our code step-by-step.

For your convenience, the underlined keywords should be your focus. Don’t know what they are? No problem, you’ll learn by doing. You could however google these terms to at least get an idea of what they’re used for.

What do we need from you?

At Mixvoip, we value passion over credentials. While degrees and extensive work experience are appreciated, they are not our primary focus. What we truly seek are individuals driven by a genuine love for coding and a desire to learn and grow.

Good command of English is important as our diverse teams use it as a common medium for communication.

Stepping into the role of a junior, it's natural that you won't have all the answers right away. And irrespective of your past experiences, every company, Mixvoip included, has its distinct business logic. Always feel encouraged to ask questions and seek clarity when needed. The quality of your code reflects your understanding of the broader picture.

Keep in mind that every developer, regardless of their experience, can overlook more efficient solutions or make an error. If you think of a better approach or see an opportunity for improvement, share it with the team. Collaborative efforts often lead to collective growth, and there's always something new for someone to learn.

I'm 34 years old and have grown with this company since 2012. This is my first and only job, and I'm proud to be among the most senior employees here. Although I don't have a college degree, I've learned a lot from the years I’ve been part of Mixvoip, and I'm always eager to learn more.

Outside of work, I enjoy playing strategic games like Magic the Gathering and chess, as well as solving logic puzzles like in escape rooms. I’m always up for any tabletop game, but I also enjoy video games as long as it’s not a toxic shooter game.

I competitively play table tennis for the club DT Osper. We thank Mixvoip for being our sponsor and we invite Mixvoip employees to an inter-club tournament every year.

I’ve been married to a Filipina since 2021 and we have a 5-year-old rescue dog from Romania who's been part of our family since 2022. She generally doesn’t trust people and will keep her distance, and doesn’t want to go to crowded or loud places. She’s quite energetic and playful with her friends, even if they don’t match her enthusiasm.
