Summary
👤
Senior🎓
Top SchoolMoinak Ghosh is a Principal Engineer with over two decades of systems and performance engineering experience, currently driving core platform work at Rubrik after roles at AWS, Goldman Sachs, Sun Microsystems and networking startups. He brings deep expertise in Unix internals, parallel/vector computing, performance optimization and systems programming across Solaris, Linux and networking stacks. His career includes founding contributions to OpenSolaris live media (BeleniX), a PKI and SSL management engine for Cisco appliances, and production-grade R&D like the Pcompress parallel deduplication engine. Comfortable in low-level code and high-level system design, he has repeatedly delivered inventive fixes and tools—from AWK bug patches to interposer libraries that backport glibc vector optimizations. Based in the Bay Area, he pairs rare historical perspective (from 8-bit BBC Micro to modern cloud platforms) with hands-on implementation skills across C/C++, assembly, Java, Python and PL/SQL. Notably, his early competitive wins and longstanding open-source work reflect a blend of curiosity-driven engineering and practical product impact.
