## Job description

At Classiq Technologies, we’re shaping the future of quantum computing.

Our mission is to make quantum computing practical and impactful by bridging the gap between hardware and real-world applications. Our platform enables developers and enterprises to design, optimize, and deploy quantum algorithms at scale, supporting teams from early exploration to production-ready quantum solutions across diverse hardware architectures.

Classiq is trusted by Fortune 500 leaders, leading research institutions, and global governments. We accelerate the quantum era by transforming advanced quantum theory into scalable, usable technology.

Quantum error correction and fault-tolerant quantum computing are central to the future of the industry and a strategic focus area at Classiq. Our R&D organization develops the technologies, software infrastructure, and workflows that will enable the transition from noisy quantum devices to practical logical quantum computing.

We are seeking a Quantum Software Engineer to help build the software foundation for Classiq’s fault-tolerant quantum computing capabilities.

As a Quantum Software Engineer, you will design and develop the software infrastructure, APIs, and workflows that enable fault-tolerant quantum computing within the Classiq platform.

Working closely with quantum error correction researchers and GPU engineers, you will transform advanced research and prototypes into scalable, maintainable, and production-ready software. You will play a key role in shaping the architecture of systems that support logical quantum computing and future fault-tolerant workflows.

### What you'll do

- Design and implement software infrastructure for fault-tolerant computing workflows

- Develop APIs, libraries, and internal frameworks that support quantum error correction and logical computing capabilities

- Collaborate with researchers and engineers to transform algorithms and prototypes into production-quality software

- Build scalable, maintainable, and well-tested systems

- Contribute to architecture, design, and technical decision-making across multiple components of the platform

- Integrate simulation, decoding, resource estimation, and execution workflows into the broader Classiq ecosystem

- Contribute to end-to-end demonstrations and customer-facing solutions

- Work closely with R&D, engineering, and product teams to deliver new capabilities

### Who you are

- 5+ years of software engineering experience

- Strong software development skills in Python

- Experience designing and building production-quality software systems

- Strong understanding of software architecture, APIs, testing, and maintainability

- Experience working with complex technical systems and large codebases

- Strong problem-solving and debugging skills

- Ability to independently lead technical projects from design through delivery

- Excellent communication and collaboration skills

### Bonus points

- Experience with scientific computing or simulation software

- Experience building SDKs, developer platforms, or technical products

- Experience with cloud-native systems and scalable infrastructure

- Experience working closely with research teams

- Familiarity with quantum computing concepts

- Experience with Python performance optimization

**Live in Classiq’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role.

We remove it as soon as it disappears at source.
