Senior Software Engineer (CALC engine) in United States at Jobgether

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 decision intelligence platform, focusing on the design and optimization of a complex Java-based calculation engine that powers large-scale, multi-dimensional analytics. You will work on a system where correctness, precision, and low-latency performance are equally critical, contributing directly to the execution of enterprise decision automation. The position involves close collaboration with product and engineering teams to translate complex modeling requirements into efficient, executable systems. You will help shape the evolution of a proprietary calculation language that is dynamically compiled into runtime execution structures. This is a deeply technical, backend-focused role ideal for engineers who enjoy working on engine-level systems and solving performance-critical challenges. The environment is fast-moving, highly collaborative, and centered on building reliable, high-scale computation systems used by global enterprises.

In this role, you will design, implement, and optimize core components of a high-performance calculation engine, ensuring accuracy, efficiency, and scalability across complex computational workloads.

• Design and implement high-performance, low-latency Java-based calculation engine components
• Work on the core multi-dimensional OLAP engine responsible for complex enterprise computations
• Collaborate with product teams to translate modeling and system requirements into executable technical designs
• Develop and refine runtime execution logic for a dynamically compiled modeling language
• Optimize JVM performance, including memory management, threading, and garbage collection behavior
• Ensure correctness-first implementation practices while balancing system performance and scalability
• Communicate complex technical concepts clearly across engineering and product stakeholders
• Contribute to the evolution of internal language design and engine architecture
• Participate in code reviews and enforce high engineering standards across core systems
• Support continuous improvement of system reliability, latency, and computational efficiency

This role requires deep expertise in backend engineering and performance-critical systems, particularly within Java-based architectures, compilers, or database-like engines.

• Strong backend software engineering experience with deep expertise in Java
• Advanced understanding of JVM internals, including threading, memory allocation, and garbage collection
• Experience building or optimizing low-latency, high-performance systems
• Strong knowledge in at least one of the following: compiler design, database engines, or front-office trading systems
• Experience designing or working with programming or domain-specific languages is highly valued
• Strong analytical and problem-solving skills with a correctness-first mindset
• Ability to work on complex, highly technical systems with performance constraints
• Experience using modern developer tools, including AI-assisted engineering tools (e.g., Claude Code) is a plus
• Nice to have: experience with Spring, multi-dimensional modeling, Lambda architecture, or planning systems
• Strong communication skills and ability to collaborate in cross-functional engineering environments

• Competitive annual compensation up to $230,000
• Equity participation with meaningful long-term value potential
• Comprehensive medical, dental, and vision insurance coverage
• 401(k) retirement plan
• Flexible paid time off policy
• Generous parental leave programs
• Hybrid and flexible working environment
• Access to stocked office kitchens with snacks and beverages (for onsite days)
• Global, distributed engineering organization with international teams
• Opportunity to work on cutting-edge decision intelligence and AI-driven systems
• Inclusive workplace with strong focus on engineering excellence and innovation
