Senior Software Engineer (CALC engine)

This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Senior Software Engineer (CALC engine) in the United States.

This role sits at the core of a high-performance, Java-based calculation engine powering advanced decision intelligence systems used by global enterprises. You will work on a complex multi-dimensional OLAP engine where correctness, precision, and performance are equally critical. The position involves designing and optimizing low-latency computation systems that dynamically compile modeling languages into efficient runtime execution. You will collaborate closely with product and engineering teams to translate complex design decisions into robust, production-ready implementations. This is a highly technical environment where deep systems thinking, performance tuning, and architectural rigor are essential. You will contribute directly to the evolution of an AI-driven platform enabling large-scale automated decision-making.

• Design and implement high-performance, low-latency calculation engine components within a complex Java-based OLAP and decision modeling system.
• Collaborate with product teams to translate functional and technical design decisions into executable, production-grade engineering solutions.
• Optimize runtime performance, memory management, and JVM behavior to ensure correctness and scalability of computation-heavy workloads.
• Contribute to the development and evolution of a domain-specific modeling language and its dynamic compilation into runtime execution structures.
• Ensure system correctness and quality by applying rigorous engineering standards and advocating for a “correctness-first” approach across the codebase.
• Communicate complex technical concepts clearly to cross-functional stakeholders, including engineering peers and product leadership.

Requirements:

• Strong experience in backend software engineering with a focus on high-performance or systems-level development.
• Advanced proficiency in Core Java, including multithreading, garbage collection tuning, memory allocation, and low-latency optimization.
• Deep understanding of JVM internals and performance characteristics in production environments.
• Experience in at least one of the following domains: database engine development, compiler design, or low-latency financial systems.
• Demonstrated ability to design or work with programming languages, modeling systems, or complex execution engines.
• Strong analytical and problem-solving skills with a focus on precision, scalability, and system correctness.
• Nice to have: experience with Spring, multi-dimensional modeling, Lambda architecture, or prior exposure to planning systems and AI-assisted development tools.

Benefits:

• Competitive salary with equity and stock options
• Comprehensive medical, dental, and vision insurance
• 401(k) retirement savings plan
• Flexible paid time off and strong work-life balance culture
• Generous parental leave policies
• Flexible hybrid/remote working environment
• Access to office amenities including snacks and beverages when onsite
• Career growth opportunities within a global engineering organization
