Carmen Sánchez de Muniáin Muro

Talent Acquisition Specialist

At Semrush, we take a serious and comprehensive approach to hiring new people. We welcome those who are professionals in their field and passionate about their work to join our team.

A “five-minute interview” or “get a job in three clicks” approach is not the way we work.

During the interview, we ask candidates to talk about themselves and their background in detail. We try to discover the most important aspects about the way someone works and their personality before a job offer is made.

Once the resume is received it will be reviewed by a member of the Talent Acquisition team. We try to provide feedback within three working days.

Flexible approach for an interview format

We’re flexible and open for both online interviews and personal meetings at the offices. Choose the option that’s most suitable for you!

In order for the online meetings to be productive, we suggest following these tips to make sure you are set up well:

• Join the interview from a laptop or desktop computer (not a smartphone). You may need to print something or present your screen during the interview.
• Please turn on your camera. Visual communication is especially important for us.
• Choose a quiet place to talk. Attending an interview from the street is not a good idea.
• Keep your phone at hand in case there are technical issues that mean we have to continue the interview by direct call.

Good luck!

Product & Tech

Engineers, data specialists, product managers, and product designers work closely together as one team at Semrush. Everyone shares a strong product mindset—thinking not only about how things are built, but about the value they create for our customers.

Our P&T teams are based across most Semrush office locations—in Spain, Germany, the Netherlands, Poland, Cyprus, the Czech Republic, Serbia, and even Vietnam! As the name suggests, they all work on creating and developing Semrush products.

There’s a dedicated branch focused on developing new products, another driving growth strategies & innovation, and a third responsible for technical excellence. Importantly, a separate team oversees product operations to ensure all processes run smoothly. This structure helps us stay focused while keeping our finger on the pulse, and improve our products in line with the constantly evolving tech environment.

A transparent career framework supports our colleagues in deepening their expertise and developing into Staff and Principal roles. For those eager to lead people and teams, management paths are also available. For instance, there’s a possibility to become a Tech Lead Manager (TLM) within the engineering scope where you’ll be able to combine team leadership with hands-on technical work.
