Algo Developer (Java / Data Structures / High-Performance)

About the project
We’re working with a US-based FinTech company that builds large-scale systems for monitoring financial and crypto markets, detecting manipulation, fraud, and compliance risks. The product handles huge volumes of data, high-load systems, and complex business logic, so the team is looking for strong engineers.

It’s a long-term, stable cooperation: the client has been partnering with us for several years, and 20+ of our specialists already work within their teams.

Requirements

• Strong Java expertise (5+ years), recent hands-on
• Excellent data structures & algorithms
• Experience manipulating large data sets in memory (performance- and memory-critical code)
• Solid multithreading / concurrency
• English B2+ (comfortable communicating with the client team)

Nice to have

• High-load / high-throughput systems
• Kafka or similar streaming
• Redis or other in-memory stores

What you’ll do

• Design and build algorithm-heavy components processing large in-memory data sets
• Optimize for speed, memory footprint, and correctness under load
• Pick the right data structures and approaches for each problem
• Keep code well-tested and reliable
