Software Engineer, Back - end

Software Engineer, Back-end

As a Back-end Engineer on the Boulder Opal Scale Up team, you'll be at the forefront of building the software backbone that powers the future of quantum technology. You'll work side by side with brilliant engineers and researchers, designing and delivering scalable, high-performance systems that bring groundbreaking science into the real world.

From SDKs to cloud-based platforms, your work will shape the tools researchers and customers use every day. You'll not only develop world-class backend systems but also help translate cutting-edge research into production-ready solutions, bridging the gap between quantum experiments and reliable software.

Suppose you're excited about building robust systems, tackling complex problems, and exploring the edge where software meets quantum physics. In that case, this is your opportunity to make a real impact in one of the most exciting fields in technology today.

What you'll be doing:

• Build impactful systems: Design, develop, and optimize scalable backend applications in Python that power real-world quantum technology.
• Engineer for performance: Create high-efficiency service-to-service communication using modern protocols.
• Bridge science and engineering: Work hand-in-hand with researchers to translate cutting-edge research code into production-ready solutions, while sharing engineering best practices.
• Deliver end-to-end solutions: Partner with product, frontend, and infrastructure teams to ship integrated features used across Q-CTRL's products.
• Champion quality: Implement and enforce best practices for code quality, security, and operational excellence.
• Solve tough problems: Troubleshoot, optimize, and enhance system performance and reliability at scale.
• Shape reusable architectures: Develop product features that promote flexibility, reuse, and scalability across multiple business cases.
• Contribute broadly: Take on other responsibilities aligned with your skills and experience and grow into new ones with support and training.
• Other duties within the Employee's skills and experience, or with reasonable training.

Ideally you'll have:

• 5+ years of backend engineering experience with Python, Rust, C++, or similar.
• A track record of collaborating across research and engineering to solve hard technical challenges.
• Strong problem-solving skills and a proactive, ownership-driven mindset.
• Strong understanding of domain driven design, service oriented architecture, asynchronous processing, and software testing.
• Excellent communication and teamwork skills across agile, cross-functional groups.
• Experience designing, implementing, and maintaining efficient algorithms and statistical models.
