DevOps Junior Engineer

Red Black Tree is an entirely Serbian software company with over nine years of experience in the industry. Our offices are located in Belgrade and Čačak, with approximately 40 team members at the moment.

Our focus is on software development, mostly for clients in the USA, Europe and Asia. We’ve been dedicated to quality assurance, meeting deadlines, professionalism and personal progress. We are a team that provides more than it's promised - whenever it’s possible, which is the case most of the time. That’s how we have acquired high-quality collaborations and long-term projects which provide us with stability.

We value a friendly and positive environment - that’s why we put an extra effort into keeping everything exceptional, from relations with co-workers to the office equipment.

Technologies are carefully selected based on the project requirements. Those are mainly complete systems, which include Mobile apps, Web applications, Backend APIs, databases, containerization and Cloud, which will help you acquire a broad and high-quality knowledge base. We’re not afraid to adapt to modern technologies, just like we did with e.g. Angular, React, Vue.js, as well as .NET Core, Elixir, Kotlin, Python and others before they became widely used and popular.

If you love programming and want to excel at it - let us know! We are always on a lookout for talent to join us.

We are a team of a dozen people, developing a complete software system for a US non-profit, iMentor. Because we know that while talent is equally distributed, opportunities are not, RBT partners with iMentor for the last 4 years in their fight to give every young person a fair chance to graduate college by matching every student with a committed college-educated mentor. Together, we help students in over 50 high schools and 14 cities across the US to fulfill their potential.

The Platform is used by mentees and mentors to communicate, work together on lessons that prepare them for college, and let iMentor’s program managers to supervise thousands of pairs. Our team focuses on design, development, and maintenance of the iMentor platform.

We have built a cloud based SaaS from scratch, with a backend written in Python and Flask using Docker, that queries PostgreSQL, Redis, and MongoDB, and presents using Angular, Swift, and Kotlin.

We’re looking for developers who can understand and describe technical tradeoffs, think creatively about paying down technical debt while simultaneously delivering beautiful solutions, and want to change the world for young people.

We are developing a secure, inclusive and flexible online therapy platform. It was built to provide improved access to mental health professionals, through an affordable, simple-to-use video conferencing platform that takes the hassle out of organising a practice with marketing, bookings, reminders, billing and collections taken care of. A hand-picked team of counsellors and psychiatrists offer their services to both the general public and to institutional clients ranging from Universities to businesses (such as AXA, the second largest insurance company in the World) to public sector bodies (such as the NHS, National Health Service).

Our small but powerful team steered full system design and specification, provided consulting, software development, DevOps, and other IT services in the past two years.

We have built the whole system from scratch using Python, Flask, PostgreSQL, Vue.js, Nuxt.js, Docker, Terraform, and AWS Cloud.

As the user base, functionalities, and the expansion plans grow rapidly, the team has to expand too - which is why we would like to hear from you!
