Senior Quantum Software Engineer Jobs in Washington

Job Number: R0244207 Quantum Scientist and Error Correction Specialist The Opportunity : Are you driven by the challenge of pushing quantum technology to its next frontier? Do you thrive at the intersection of deep science, creative engineering, and mission-focused innovation? If you're excited to turn groundbreaking theory into practical capability, we have an opportunity that aligns with your passion. As a Quantum Error Correction (QEC) Scientist, you will help shape the architecture of novel quantum computing architectures. You'll collaborate closely with theoretical and experimental physicists, engineers, and cross-disciplinary innovators to design the next generation of fault-tolerant quantum systems. In this role, you will guide the development of QEC concepts and protocols tailored to the selected architecture, optimize resource requirements, and advance the efficiency of error-corrected quantum operations. Your work will include designing syndrome-extraction strategies, analyzing logical-gate fault-tolerance, developing error mapping approaches, and creating rigorous logical-level verification and validation methodologies. This is your chance to help turn the promise of quantum computing into real-world capability, and to be part of a team helping to redefine what's possible. What You'll Work On: * Develop and optimize fault-tolerant protocols compatible under realistic architectural constraints.
* Analyze and improve qubit connectivity in a reconfigurable architecture and exploit transversal and blockwise operations to improve performance and reduce computational time.
* Design logical-gate implementations such as Clifford & non-Clifford and teleportation-based gates in a highly modular architecture.
* Compare magic-state preparation methods, magic-state scheduling, and inventory management.
* Collaborate with atomic and solid-state physicists to determine implementation constraints and resource optimization pathways.
* Map QEC scheduling constraints onto architectural layout, minimizing noisy operations, and reducing QEC's temporal overhead.
* Co-design logical decoder requirements with embedded firmware and control-electronics teams supporting fast, low-latency operations.
* Contribute to the logical-level Verification and Validation (V&V) pipeline.
* Collaborate with modeling and simulation experts to integrate noise models into QEC protocols and determine fault-tolerance requirements and logical-level performance.
* Collaborate with software developers to integrate QEC models and decoders into Booz Allen's quantum software stack.
* Support business development consistent with mission - aligned efforts.
* Mentor junior scientists and coordinate with academic and industry partners Join us. The world can't wait. You Have: * 5+ years of experience in quantum fault-tolerance theory, decoders, and stabilizer formalism
* Experience in simulation tools including Python, Julia, QEC frameworks, and tensor-network libraries
* Experience with peer-reviewed research in quantum error correction
* Ability to collaborate with experimental teams to facilitate physical implementation
* Top Secret clearance
* Doctorate degree Quantum Information Science, Physics, Electrical Engineering, Computer Science, or Applied Mathematics Nice If You Have: * Experience with noise modeling and designing QEC protocols for hardware-constrained architectures
* Experience with qLDPC codes and corresponding decoders
* Experience with reconfigurable qubit architectures
* Experience with quantum networking, photon-mediated entanglement, and heralding systems
* Experience with quantum characterization, verification, and validation (QCVV) techniques
* Experience facilitating milestone demonstration events Clearance: Applicants selected will be subject to a security investigation and may need to meet eligibility requirements for access to classified information; Top Secret clearance is required.
