Senior🎓
Top SchoolRichard Carback is a mission-driven cryptographer and serial entrepreneur with 11+ years building privacy-preserving systems, voting technologies, and post-quantum communication protocols. As co-founder and technical leader at multiple startups (including XX Network, Lexumo, Elixxir, and now Postquant Labs), he combines hands-on cryptographic systems engineering with product leadership across React, Python, and Go stacks. His work spans applied research in election privacy, LLVM-based vulnerability analysis, and large-scale distributed messaging, reflecting a rare blend of academic rigor (Ph.D. in Computer Science) and shipping-first startup execution. He has repeatedly moved from founding CTO roles into focused contributor and consulting positions, demonstrating an ability to hire and scale teams then return to deep technical work. Based in Everett, Massachusetts, he’s quietly bridged military, academic, and commercial projects to deliver auditable privacy technology with real-world deployments.
