Unify Technologies - Senior Software Engineer - Java

Job Title : Senior Software Engineer - Core Java (Distributed Systems)

Employment Type : Full-time

Experience Level : 4- 11 years

About The Project

Were building a high-performance distributed backend system designed for scale, reliability, and low latency. This is a non-microservices architecture, and we do not use Spring Boot. Instead, we rely on solid Core Java engineering and proven architectural patterns to deliver robust solutions.

If youre passionate about solving complex problems with clean, efficient code-and prefer working outside the typical microservices/Spring Boot paradigm-this is the role for you.

Key Responsibilities

• Design, develop, and maintain backend components using Core Java
• Build scalable and fault-tolerant systems in a distributed architecture
• Optimize performance, memory usage, and throughput
• Collaborate with cross-functional teams to deliver high-quality software
• Participate in architectural discussions, code reviews, and debugging
  
  

• Strong hands-on experience with Core Java (Java 8+)
• Deep understanding of multithreading, concurrency, collections, and JVM internals
• Experience working on distributed systems or large-scale backend platforms
  
  

• Experience with C++ : Native module integration or performance-critical components
• Experience with Big Data technologies : Hadoop, Spark, Kafka, etc.
  
  

• This project does not use microservices
• This project does not use Spring Boot
• We focus on lean, efficient architecture and Core Java fundamentals
  
  

• Familiarity with messaging systems (Kafka, RabbitMQ)
• Exposure to performance profiling and memory optimization
• Experience with CI/CD tools and Git
  
  

• Work on cutting-edge distributed systems with real-world impact
• Be part of a lean, agile team that values deep technical expertise
• Influence architecture and engineering decisions
• Competitive compensation and career growth
