Job description

Here at Mindera, we are continuously developing a fantastic team, and would love it for you to join us.

We are looking for a Senior Full-Stack Software Engineer who not only brings strong technical skills but also excels in team fit, communication, and collaboration.

You will be responsible for designing and building high-performance, secure, and scalable full-stack solutions — with a strong focus on Java (Spring Boot), React, and Next.js, ensuring seamless integration between server-side logic and the front-end experience.

If you are approachable, communicate clearly, and enjoy working in a collaborative and positive team environment, we’d love to hear from you.

National and international expected traveling time varies according to project/client and organisational needs: 0%-15% estimated.

Soft Skills – Top Priority

• Clear and effective communication, able to express ideas and collaborate efficiently in a team.
• Strong English proficiency.
• Approachable and easy to work with, contributing to a positive team atmosphere.
• Team fit is key — we value people who are enjoyable to work with as much as technical skills.

Technical Skills

• Strong experience in Java (Spring Boot), React.js, and Next.js.
• Solid understanding of backend architecture, microservices, and database management (SQL/NoSQL).
• Experience working with Redux or similar state management tools.
• Familiarity with GraphQL and REST APIs.
• Solid skills in HTML5, CSS3, and CSS pre/post-processors (SASS, LESS, PostCSS).
• Experience with testing frameworks such as JUnit, Mockito, Jest, and React Testing Library.
• Knowledge of performance optimization, observability tools (e.g., Grafana, Core Web Vitals), SEO, and accessibility best practices.
• Varied tech experience is highly valued — exposure to different stacks and environments.

Ways of working

• Agile methodologies such as Scrum and Kanban.
• Passionate, self-driven, and comfortable working with little supervision.

The Things We Really Care About:

• Health Insurance, because health comes first
• Flexible working hours
• Open holidays, take the time you need for yourself
• Profit distribution for everyone
• Mindera Annual Trip, Sports, and sharing groups to connect and have fun!
• Training & conferences, create your own training plan

Other Good Things:

• Choose Laptop & Peripherals that best suit your needs
• Hotspot with unlimited usage, for work or Netflix
• Remote culture: We have an office in Casablanca, but Minders work remotely from all over Morocco.
• At the offices, we have a wide range of snacks to keep you fed and healthy and Partnerships with local businesses
