Job description

Senior Software Engineer (Java)

We’re looking for a Senior Software Engineer with a strong Java background and real experience building distributed systems. You understand concurrent programming at a deep level, you’ve worked on data flow or streaming infrastructure, and you know how systems behave when the load is real and the data keeps moving. You’ll be working on a platform used by thousands of organizations worldwide to move and manage critical data — the kind of work where your engineering foundations genuinely matter.

What You’ll Do:

• Design and develop backend components in Java for a large-scale distributed data flow platform.
• Write concurrent, high-throughput code that performs reliably under production conditions.
• Contribute to the design and improvement of stream processing and data ingestion pipelines.
• Collaborate with cross-functional teams to understand requirements and deliver scalable solutions.
• Participate in code reviews and help maintain high standards of engineering quality across the codebase.
• Investigate and resolve performance, reliability, and correctness issues in distributed system components.

What We Are Looking For:

• 5+ years of experience in IT roles.
• 3+ years of experience with Java as a primary programming language.
• Solid background in distributed systems design and operation.
• Strong understanding of concurrent programming concepts and patterns.
• Experience with data flow, stream processing, or data pipeline infrastructure.
• Open source contribution experience is a plus.
• Advanced proficiency in English.

Benefits:

• Remote Work.
• Excellent compensation in USD or your local currency if preferred.
• Hardware and software setup for you to work from home.
• Flexible hours: create your own schedule.
• Paid parental leaves, vacations, and national holidays.
• Innovative and multicultural work environment: collaborate and learn from the global Top 1% of talent.
• Supportive environment with mentorship, promotions, skill development, and diverse growth opportunities.
