• High-Scale Distributed Engineering: Build and optimize resilient, scalable services operating under strict high-availability, low-latency, and strong data consistency requirements.
• Data-Driven & Cross-Functional Collaboration: Partner directly with Product Managers, Solution Architects, and engineering peers to design, refine, and deliver robust data-driven risk management capabilities.
• Risk Management & Technical Visibility: Proactively track technical risks and system issues, reporting progress and status clearly to stakeholders.
• Mentorship & Process Ownership: Mentor junior engineers, drive CI/CD best practices, and contribute to maturing development standards and team-wide Agile engineering practices.

Requirements

• API Architecture: Hands-on experience developing and integrating server-to-server APIs using REST and gRPC.
• Distributed Systems Mechanics: Proven background building, scaling, and operating large-scale distributed systems characterized by high availability, low latency, and strong data consistency.
• CI/CD & Engineering Culture: Demonstrated CI/CD mindset with experience in automated testing, continuous integration, and modern deployment pipelines.
• Communication & Leadership: Strong written and verbal English communication skills, with a proven ability to explain complex technical topics clearly to diverse audiences.

Nice to have

• Stream & In-Memory Computing: Hands-on experience with real-time stream processing and in-memory computing paradigms.
• Big Data Ecosystem: Exposure to Big Data processing frameworks and platforms such as Hadoop, Apache Spark, or MapReduce.
• Caching & High-Speed Data: Practical experience with Redis or other distributed caching layers for ultra-low latency data access.
• Financial & Risk Domain: Prior experience working on risk engines, fraud detection, or payment infrastructure in regulated financial environments.

We offer

• Opportunity to work on bleeding-edge projects
