Role description

We are a compact, high-performing IT team driving a fintech startup focused mainly on automating highway toll payments and e-vignette sales. Our backend squad maintains a robust infrastructure handling high-volume transactions and integrations with banking systems and highway operators.

We value autonomy, technical excellence, and a proactive approach to system reliability.

As a Java Developer, you will play a key role in scaling our core products. You will work on expanding our microservices ecosystem while ensuring the stability of our central application. This role requires navigating between maintaining high-availability systems and designing new, scalable features in the cloud. You will be directly involved in the full development lifecycle - from estimating tasks to deployment and monitoring.

What You'll Do

• designing and developing scalable microservices using Java and Spring Boot,
• maintaining and optimizing the core application based on JEE,
• collaborating closely with Front-end Developers, the Product Owner, DevOps, and ICT teams to deliver high-quality solutions,
• integrating with external APIs (Banks, Highway Operators, Partners),
• writing unit and integration tests to ensure system stability,
• participating in technical analysis and estimation of new functionalities.
  
  

What We're Looking For

• min. 3 years of commercial experience in Java development,
• strong knowledge of Java 11+, Spring Boot,
• experience with Apache Kafka or other message brokers (we use it heavily for async processes),
• proficiency in SQL (PostgreSQL or similar) and ORM frameworks (Hibernate/JPA),
• practical knowledge of AWS services and containerization (Docker, Kubernetes/EKS),
• ability to estimate tasks realistically and work in a team focused on delivery,
• very good command of English (min. B2 for documentation and reading technical specs).
  
  

Nice To Have

• knowledge of Agile methodologies,
• experience with relational databases storing large datasets, including query optimization and database performance tuning techniques,
• experience working with containers and cloud services (Docker, Kubernetes, AWS).

• flexible working hours,
• independence and responsibility for assigned tasks,
• cooperation and participation in unique projects,
• opportunities for professional development,
• friendly working atmosphere, team support, no dress code,
• access to modern tools and technologies.
