What the successful job applicant will be working on:
7Mind’s first backend was built with Ruby on Rails by an agency. Later additions were written with Elixir in self-contained services. This system grew in complexity over time and the team came to the conclusion that the small team of backend engineers couldn’t reap the benefits of multiple, independent services, and as such the operational overhead wasn’t worth it.

Since late 2022 we’ve been slowly moving towards a single, monolithic codebase, still applying separation of concerns principles by applying DDD techniques to identify and separate distinct parts of the codebase. This modulith we’re building is meant to replace large swaths of the existing services, while reducing complexity in areas where 7Mind doesn’t have a core-business interest.

In addition we’re on the cusp of build a completely new product, which is a very exciting opportunity to reflect on our learnings of the past.

About the interview process

Usually we begin with a first call which acts as a first technical screening and getting to know each other. This will be done by backend colleagues who you’re also going to work with.

Based on this we decide how to proceed. The last round in our application process is always a “meet-the-team” round, where you get the opportunity to meet multiple members of the Product Team.

How to apply


I can vouch for this job posting! Awesome company as far as I could see. I applied long time ago, naturally didn’t get it, but the process was great and the people were quite nice.
Please apply, it’s worth it!!

@wolf4earth What may be interesting for possible candidates is the form of agreement, especially the willingness to sign a different type of contract. In linked job offer there is only Permanent employee with lots of employee-specific perks. Many people for various reasons (like taxation) prefers for example B2B contract.

Yeah, pretty interesting pointer. If we talk about an international colaboration, then B2B is a must.

I don’t know details but we do have colleagues outside of Germany (Portugal, US, etc.) and I know that we’re working on streamlining this.
