Senior Backend Developer

We are looking for a motivated and curious developer to join our team working on a complex CRM platform, built using Django and Python. Experience with Python is not a strict requirement; what matters more to us is your willingness to actively work in it and grow with support from the team. 

Our CRM system is designed as a multi-tenant platform, enabling each company to have its own self-care portal and checkout flow. It integrates with global payment gateways for seamless transactions, and is also connected to EON services to support streaming content delivery. 

Performance and scalability are at the core of our architecture. The system leverages multithreading, multiprocessing, caching strategies, and a robust CI/CD pipeline powered by Kubernetes, Docker, and Jenkins. Since we manage the full delivery cycle ourselves, code quality, reliability, and efficiency are our top priorities. 

If you're eager to work on a high-impact product, gain deep technical experience, and grow in a collaborative environment, we'd love to hear from you. 

What you'll have here: 

• In-house products: Working on products that we use every day and have millions of users. Some of them are your friends, neighbors, and family members. We are our own clients. Our opinions and experiences directly shape the products that we design and create.  
• People: You will work with experts, community leaders, and senior engineers who made these products from scratch. They will reveal to you how the whiteboard idea turns into a worldwide platform.  
• Internal learning sessions and innovation challenges: We are an innovation center primarily and you can be part of initiatives, research, and focus groups… and don’t miss taking a place in innovation challenges and hackathons.  
• Tech stack: We are tech agnostic, and programming languages are just a tool, but they can make our job easier if we choose the right tool for the job.  
• Engineering mindset: We are engineering our solutions from the ground up using open-source tools and customizing them to our needs. We worry about performance; we analyze and observe our system. We are not throwing money at the problem; we actually care if things could be more optimal.  
• Career growth: We strongly believe in feedback culture and development plans.  
• Community: You want to share your knowledge with the community? We are organizing meetups (DevOps Talk Belgrade) and internal workshops. You are more than welcome to participate. If you are not a great speaker, that is also fine.  

Your responsibilities: 

• Building, designing, and creating platform in Python  
• Ensuring high performance and availability as well as managing all technical aspects of the CRM.  
• Designing APIs and developing new tools for migrations.  
• Building and maintaining new microservices that enable integration with the core platform.  
• Recommend code and design optimizations to improve the scalability of the applications and maximize performance.
• Leading, mentoring, and growing the community of engineers.  
• Collaborating and coordinating work with other feature teams.  
• Creating POCs and documenting technical designs and solutions.  
• Proposing, planning and implementing best engineering practices  

What we're looking for: 

• 5+ years of experience as a Backend Developer.   
• Hands-on experience in creating efficient, scalable, and customizable applications tailored to the specific architectural needs.  
• Experience working with CI/CD tools (Jenkins, Spinnaker, ArgoCD, GitLab, or similar).  
• Proficient understanding of code versioning tools (such as Git).  
• Experience with working on highly scalable and traffic heavy websites.   
• Knowledge of Agile Development Methodology, Continuous Integration, and Unit testing.  
• Ability and desire to work in small and dynamic teams.  
• Willingness to learn modern technologies and propose innovative solutions.  
• High proficiency in written and spoken English.  
• Good verbal communication and good interpersonal skills.  

What will be considered as a bonus:   

• Django framework experience or other Python web framework. 
• Proficient knowledge of and passion for the Linux operating system (Ubuntu, Debian, CentOS).  
• Experience with Kubernetes and any of the container runtimes.  

We have more than cookies: 

• Flexible working environment – we have offices in Belgrade and Ljubljana.   
• Private healthcare  
• Gifts for your special days  
• “Healthy” Friday – not always healthy snacks on Fridays  
• 25 vacation days  

Here’s the thing: We come to work every day to face exciting and challenging creative problems. And we come armed with an extremely Agile mindset and a bundle of opportunities for career growth and personal development plans.

We come and go relaxed and happy as we know United Cloud has our back, making sure our work and private life are in a perfect balance. Our team is made of smart people, ambitious enough to make the change and brave enough to move boundaries. There is always room for more individuals like that, so send us your CV.
