Cluj-Napoca, Cluj County, Romania

At Mindera, we believe that software is built by people, for people, with high-performance systems that impact users worldwide.

We value empathy, self-organization, and a positive attitude. If you are approachable, communicate clearly, and believe that team fit is just as important as technical expertise, you'll feel right at home here.

At Mindera, we encourage the use of AI to assist with coding and related tasks. We find a person's skill in engineering and software craft has a big impact on long-term successful delivery, with or without AI. Our goal in the interview process is to understand the candidates' knowledge and skill with engineering. If you need to, or plan to use AI, please be transparent with us when you're using it, to avoid issues and misunderstandings that can either impact your chance of securing the role or impact your success at Mindera.

When you join Mindera, we welcome you into a fun and politics-free work culture, built on the principles of lean and self-organisation.

Note: Depending on the project and our clients' needs, you may get the chance to pack your bags and take off every now and then. Typically, we estimate travel time to be between 0% and 15%.
