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, automating complex processes and supporting teams from beginners to experts across diverse architectures.
Classiq is trusted by Fortune 500 leaders and global governments. We accelerate the quantum era with a platform that transforms bold quantum ideas into working applications.
We're seeking a Senior Software Engineer with a strong software engineering background to develop Classiq's quantum execution platform. Our execution layer runs quantum circuits and orchestrates hybrid quantum-classical algorithms across quantum hardware and simulators. You’ll build the infrastructure and abstractions that coordinate these workloads and make a rapidly evolving ecosystem of quantum computing systems, each with different capabilities, constraints, and interfaces, reliable, efficient, and usable at scale.
What you'll do
- Build systems that plan, orchestrate, and manage quantum workloads across multiple hardware providers, simulators, and cloud environments.
- Develop a deep understanding of quantum applications and backend capabilities to optimize execution performance and enable new execution capabilities.
- Maintain high standards of software quality, reliability, and engineering excellence.
- Collaborate with Product Managers, Infrastructure, other core teams and quantum experts to deliver robust production software.
Who you are
- 8+ years of experience developing complex production software systems.
- B.Sc. or higher in Computer Science, Software Engineering, Physics, or a related technical field.
- Strong hands-on experience with Python.
- Experience designing scalable backend systems, distributed systems, or workflow orchestration platforms.
- Strong architectural thinking and the ability to identify clean abstractions, reason about system tradeoffs, and turn complex technical requirements into maintainable software.
- Demonstrated ability to take complex, technical problems from exploration and design through implementation and production ownership.
- Passion for solving challenging problems at the intersection of software engineering and complex technical domains.
Bonus Points
- Prior familiarity with quantum computing.
Skills Required
- B.s.C in Math/Physics/Computer Science/Engineering
- At least 5 years of professional software engineering experience
- Strong algorithmic thinking
- Solid systems engineering background
- Proven ability to dive fast into unfamiliar code
- Strong debugging skills in complex systems
