Let’s create value together!

We’re collaborating with a leading company in financial crime prevention and fraud detection. Their platform empowers businesses to assess risk in real time, processing millions of data points per second to detect and prevent fraudulent activity on a global scale.

Currently, we are in the migration phase, modernizing the API infrastructure to ensure seamless compatibility between legacy and new systems. After this phase, we’ll move into platform enhancement, focusing on performance optimization, feature expansion, and system scalability.
 

You’ll join a highly skilled team working on real-world challenges with high-load systems, modern cloud-native solutions, and advanced communication protocols. This is an excellent opportunity for someone eager to grow fast and gain hands-on experience with cutting-edge technologies in a demanding but rewarding environment.
 

Project Highlights:

• Current focus: Migration and modernization of legacy API infrastructure.
• Next phase: Platform enhancement, scalability improvements, and feature development.
• Load profile: High throughput, real-time fraud detection.
• Team: Back-End, Front-end Developers, Solution Architect, Project Manager.
• Methodology: Agile (Scrum)/Kanban, 1-week sprints, daily stand-ups, regular demos.
• Tooling: Slack, Jira, Google Meet.
   

What You’ll Do:

• Take ownership of the backend domain, driving technical vision and architecture decisions.
• Design and implement scalable, cloud-native Kotlin-based microservices.
• Collaborate with Solution Architect on system design and long-term scalability strategies.
• Partner with stakeholders and product owners to align priorities, plan roadmaps, and deliver business value.
• Lead full-cycle delivery of fixed-price projects from kickoff to final delivery.
   

What We’re Looking For:

• Strong expertise with Kotlin and Spring Boot in production environments.
• Deep knowledge of microservices architecture, API development, and cloud platforms.
• Advanced understanding of Kafka (including Kafka Connect), gRPC, and Protobuf for real-time, high-throughput systems.
• Experience optimizing data layers with PostgreSQL, Yugabyte, and jOOQ.
• Hands-on experience with Kubernetes, AWS, GCP, and containerized environments.
• Strong architectural mindset with ability to balance technical depth and business needs.
• Excellent communication and stakeholder management skills.
• Passion for mentoring and developing engineering talent.
