Become a Martian
Join our team
At MarsBased, we intentionally grow at an organic pace to preserve our culture and maintain sustainable operations. All currently open positions are listed on the Jobs page of our website.
If you do not see a role that aligns with your specific profile but feel you would make a great addition to the spaceship, you are welcome to submit an application through work@marsbased.com.
Please note that due to the high volume of applications, we may not be able to respond to every candidate. However, we always provide a yes or no response to all the applicants we interview.
The hiring process
Behind every application is a real person, which is why our People team (HR) manually reviews every single submission.
When we review an application, we look at the big picture. Through the questions in our application form, we get a clear sense of your written communication, your motivation for joining MarsBased, and the context behind your career path and tenure at previous companies.
Alongside these insights, we evaluate your tech stack, past projects, language skills (English and/or Spanish), and location alignment, meaning we lean heavily toward hiring in Spain, Portugal, and Southern Europe.
Step 1: HR Interview
Once applications are screened, the People team invites shortlisted candidates to an initial interview.
This first touchpoint is a two-way conversation designed to get to know each other. While we evaluate cultural alignment, soft skills, and mutual expectations alongside your tech stack and past projects, it is also an opportunity for us to share details about MarsBased, our culture, and how we work, and for you to ask us any questions you might have.
All interviews are conducted entirely online via video call and typically last between 45 and 60 minutes.
Note: We do not send WhatsApp messages.
Step 2: Technical Assessment
If you successfully pass the HR interview, we move on to the technical assessment.
The technical assessment helps us evaluate how you solve real-world problems, write clean code, and communicate technical decisions. The format may vary depending on the role, and we adjust it as needed. We focus on code quality, testing, problem-solving logic, and clear documentation.
Step 3: Technical Interview
Finally, if you succeed in the technical assessment, we schedule a video call to perform a technical interview with the CTO. This is not a coding exercise, but rather a discussion to explore in depth your technical background, problem-solving approach, and past experiences.
We focus on architectural decisions, trade-offs in real-world scenarios, and how you approach challenges in daily projects. We will also walk through your technical test submission to explore your design choices and alternative solutions.
It is also a two-way conversation, so you will have plenty of time to ask us about our tech stack, engineering standards, and daily workflows at MarsBased.
Step 4: Reference Check
After successful completion of the Technical Interview, we will conduct a Reference Check process where you will be asked for 3 references, ideally from people you have reported to in previous roles. This is the final step in our hiring process before we make a decision.
Step 5: Job Offer
If everything aligns and references are verified, we will reach out with a formal offer! We will walk you through the details of the compensation package, starting date, and contract terms. Once accepted, we’ll start preparing your onboarding so you have everything ready for your first day as a Martian.
What do we value most
Some of our most important considerations when evaluating a candidate are (in no particular order):
