About Q-Block Computing: Q-Block Computing builds quantum systems that operate in the real world. The company develops quantum timing, quantum-secure communications, and quantum computing platforms engineered for the performance, reliability, and environmental resilience that mission-critical applications demand - systems designed to be deployed, maintained, and trusted by operators who cannot afford ambiguity about whether the technology works.

The long-term vision is deeper than any single platform. Q-Block is pursuing a mission to decode Nature's foundational model - to build instruments of sufficient precision and coherence that they become tools for understanding the physical universe at its most fundamental level. Commercialization and science reinforce each other by design.

About this role: The Executive Assistant is the operational backbone of Q-Block's leadership team. The role keeps calendars, travel, correspondence, and meetings running cleanly across a company that moves quickly and engages with government, industry, and international partners at a high cadence. Done well, it makes the rest of the leadership team measurably more effective.

The successful candidate is organized, discreet, and genuinely proactive - someone who anticipates what leadership will need before being asked, handles sensitive information with complete professionalism, and carries themselves with ease in front of senior government officials, defense industry executives, and technical staff alike. This is a role for someone who takes pride in running a tight operation and finds satisfaction in being the quiet reason things work.

• Exceptional organizational skills and attention to detail; demonstrated ability to manage multiple concurrent priorities with minimal supervision.
