Senior Java Developer with Kotlin
Confirmed on the employer's own hiring board on Oct 17, 2026. First seen by Alion on May 13, 2026. Mindera scores A on the Alion truth index.
At Mindera, we believe that software is built by people, for people, with high-performance systems that impact users worldwide.
We are looking for a Senior Java Developer with Kotlin Experience to join an agile, collaborative team where your voice matters as much as your code.
As an experienced developer within Mindera you need to have an excellent understanding of how to define and deliver solutions iteratively and collaboratively. You’ll be challenged to solve complex problems and build seamless user interactions to world-class standards.
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 that a person's engineering and software craft skills have a big impact on long-term successful delivery, with or without AI. Our goal in the interview process is to understand the candidate’s knowledge and skills in 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%.
