Jobs at Classiq

Design the visual language, UI, UX, and interaction patterns for Classiq’s SaaS quantum developer platform. Create polished interfaces for complex technical workflows, develop iconography and visual systems, translate quantum concepts into intuitive experiences, and help evolve the product’s design language. Collaborate with designers, product managers, and engineers in a high-autonomy environment.

Develop and enhance the execution product for quantum computing by creating new functionalities, debugging complex systems, and collaborating with teams.

Design and implement software infrastructure, APIs, and workflows to enable fault-tolerant quantum computing. Collaborate with researchers and engineers to productionize algorithms, integrate simulation/decoding/resource estimation, and build scalable, well-tested systems supporting customer-facing demos and platform capabilities.

The Senior Sales Account Executive at Classiq Technologies will manage the full sales cycle, engage with enterprise clients in quantum computing, and build strategic partnerships, driving revenue growth in an emerging market.

Lead research and development of quantum error correction and fault-tolerant techniques, design and evaluate codes, decoders, and logical qubit architectures, build prototypes and resource estimates, and collaborate with engineers and hardware partners to integrate validated approaches into scalable software.

Lead day-to-day operations of a new on-site quantum computing center: onboard, train, and support platform users; provide first-line technical troubleshooting; implement quantum applications with local customers; manage user, license and hardware access; represent the center to visitors and partners; and help stand up space, equipment, and workflows as an early founding hire.

Lead technical pre-sales with European customers: qualify opportunities, run technical discovery, deliver demos and POCs, advise on quantum algorithm adoption, and relay field feedback to product.

As a Senior Software Engineer, you will design and maintain production systems, write high-quality code, improve performance, and collaborate with various teams on software features.

The role involves developing clear narratives for a technical quantum software platform, working with product, engineering, and sales teams to communicate value and facilitate product adoption.

Lead teams in software development at Classiq Technologies, focusing on Python and TypeScript. Mentor engineers, define architecture, improve CI/CD processes, and leverage AI tools to enhance workflows.

Define technical direction for a quantum compilation stack: evaluate research, translate advances into product specs and shipped compiler/language/library capabilities, collaborate across research and engineering, produce benchmarks, documentation, and engage in external research or hardware experiments.

Develop production-grade components of a quantum compiler and high-level language (Qmod). Implement and optimize quantum synthesis algorithms, resource estimation, debugging tools, and ensure correctness and performance for real quantum algorithms in collaboration with product and algorithm teams.

Design and implement the Qmod language and compiler pipeline, develop quantum synthesis algorithms and resource estimation, optimize circuits for qubit/depth/gate constraints, build debugging tools and compiler passes, and collaborate with product and algorithm teams to deliver production-ready quantum compiler capabilities.

Lead and deliver complex quantum and enterprise IT projects in Seoul. Own full project lifecycle: planning, scheduling, risk mitigation, resource allocation, stakeholder alignment, reporting, technical demos, acceptance, and deployment. Coordinate local, regional, R&D, product, partners, and customers while ensuring contractual commitments, project governance, and continuous improvement.

Lead product strategy for enterprise deployment, security, and administration of Classiq's platform across cloud multi-tenant, dedicated/on-prem, and white-labeled modes. Define requirements for multi-region data residency, security/policy per tenant, versioning/upgrade strategy, and end-to-end account and user management. Coordinate engineering, security, sales, and customer success to deliver shippable solutions.

Lead end-to-end product for an agentic natural-language-to-quantum-program experience: define roadmap, plugin/dev-tools integration, internal harness, eval metrics, user discovery, and cross-functional delivery sequencing.
