Software Engineering Team Lead

About the Role

At Qblox, we don’t just build software; we build the engine that drives the Quantum Revolution. We are looking for a Software Engineering Team Lead to spearhead the development of the Qblox Cluster—our modular control platform that orchestrates 100+ qubit systems with nanosecond precision.

As we scale toward 1,000+ qubits and beyond, the complexity of our software stack grows exponentially. You will lead the team responsible for this orchestration, sitting at the intersection of high-level Python interfaces and low-latency quantum assembly (Q1ASM).

What You’ll Actually Do

• Lead with Technical Credibility: You’ll mentor a high-performing team of engineers, but you won't just be a "people manager." You’ll be the architectural guide, making sound decisions under the real-world constraints of time, resources, and quantum uncertainty.

• Scale the "Brain": Drive the development of the software that allows experimentalists to write experiments in Python and compile them down to our proprietary hardware.

• Process Pragmatist: You’ll have the autonomy to shape how the team works. We hate red tape—you’ll be responsible for building workflows that actually help engineers move faster, not create overhead.

• Cross-Functional Collaboration: You’ll work closely with physicists, FPGA designers, and hardware engineers to ensure our software and hardware are a seamless, high-performance unit.

Why Join Qblox?

Join a unique, hyper-growth environment where you will help bring world-changing deep-tech to the market. We offer a high-curiosity, high-performance culture where you will collaborate alongside a passionate, interdisciplinary team of top-tier scientists and engineers.

To support our team, we offer a highly attractive and comprehensive benefits package:

• Hybrid Flexibility: A healthy work-life balance with 3 days in the office and 2 days remote.

• Time to Recharge: 30 days of paid vacation per year on top of national holidays

• Future Security: Highly competitive base salary with a generous 14% employer contribution to your pension.

• Skin in the Game: Company equity (Stock Appreciation Rights) so you can share in our long-term success.

• Global Mobility: We provide a relocation package and full visa sponsorship for international hires and their families moving to the Netherlands.

About Qblox

At Qblox, we operate at the frontier of the quantum revolution, delivering the advanced control stack technologies essential for building scalable Quantum Computers. This rapidly growing field is set to impact society on a global scale. Since 2019, Qblox has grown into a dynamic company of 180+ innovative minds. With our headquarters in Delft, Netherlands, and our second office in Boston, USA, our dedicated team of physicists, engineers, and developers pushes the boundaries of quantum technology to support experimentalists across the globe.

We celebrate equality and diversity. As an exponentially growing scale-up, we welcome talented individuals who share our enthusiasm to make a real difference. Our active Diversity & Inclusion and Culture Committees work continuously to enrich our workplace, ensuring we build a team that represents a rich variety of backgrounds, cultures, perspectives, and skills.

Enough about us, what about you?

In order to really enjoy this role, we expect you will have a background encompassing the following:

• The Track Record: 7+ years in software engineering, with at least 2 years of experience leading a team (either formally or as a strong tech lead).

• Python Mastery: You have deep Python expertise and a solid grasp of software design fundamentals (SOLID, design patterns). You know when to apply them—and more importantly, when to keep things simple.

• A "People-First" Mindset: You enjoy seeing others succeed. You’ve run effective 1-on-1s, provided tough but fair feedback, and helped junior engineers level up.

• Architectural Vision: You can navigate the trade-offs of compiler design, ASTs, or intermediate representations (IRs). If you have experience with LLVM or MLIR, that’s a huge plus.

• Scientific Curiosity: You don’t need a PhD in Physics, but you should be excited to learn. Experience with the quantum/scientific Python ecosystem (Qiskit, NumPy, SciPy) is a great head start.
