## About the Role

* Bachelor's degree in Computer Science or a related field, and a minimum of 5 years of experience writing low-level, high-performance C++ code.
 * Solid knowledge of VM and compiler runtime design and implementation; familiarity with JVM internals is highly desirable.
 * Demonstrated ability to independently lead and deliver complex technical projects on time, managing competing priorities and technical uncertainty.
 * Experience mentoring engineers and contributing to a team's technical culture and practices.
 * Strong proficiency with low-level programming concepts - memory management, pointers, concurrency, and multithreading.
 * Experience using debuggers, profilers, and performance analysis tools to investigate and resolve complex problems.
 * Understanding of hardware architectures (e.g. x86, ARM), operating system internals (e.g. Linux, macOS), and languages such as Java or Rust is an advantage.

## Description

* Design, develop, maintain, and optimize high-performance, low-level C++ code for system-critical JVM runtime components and distributed client-server communication using gRPC, HTTP/2, or HTTP, ensuring minimal overhead, robustness, and reliability at scale.
 * Lead the delivery of complex technical projects - from design through production - taking ownership of outcomes and navigating ambiguity under real time and resource constraints.
 * Contribute to the technical direction of the team: participate in design discussions, challenge and pressure-test technical approaches, and ensure robust solutions through constructive peer review.
 * Collaborate across teams - represent the team's technical interests in cross-team initiatives and contribute as a peer in design and direction discussions with partner engineering groups.
 * Mentor junior engineers, sharing expertise through reviews, pairing, and practical guidance that raises the quality bar across the team.
 * Explore and adopt AI-first workflows - proactively identifying where AI tools can enhance productivity, code quality, and development processes, and helping teammates adopt effective practices.
 * Perform detailed debugging, profiling, and root-cause analysis of complex software issues.
 * Develop comprehensive tests to ensure high quality and demonstrate performance improvements.
