Job description

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, 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: Mentor a high‑performing team of engineers, serving as the architectural guide and making sound decisions under real‑world constraints of time, resources, and quantum uncertainty.
• Scale the “Brain”: Drive development of software that allows experimentalists to write experiments in Python and compile them to our proprietary hardware.
• Process Pragmatist: Shape how the team works by building workflows that help engineers move faster, eliminating overhead.
• Cross‑Functional Collaboration: Work closely with physicists, FPGA designers, and hardware engineers to ensure 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.

We provide a comprehensive benefits package:

• Hybrid Flexibility: 3 days in office, 2 days remote.
• Time to Recharge: 30 days paid vacation per year plus 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).
• Global Mobility: Relocation package and full visa sponsorship for international hires and families moving to the Netherlands.

About Qblox

At Qblox, we operate at the frontier of the quantum revolution, delivering advanced control stack technologies essential for building scalable Quantum Computers. Since 2019, Qblox has grown to 180+ minds. With headquarters in Delft, Netherlands, and a second office in Boston, USA, our team pushes the boundaries of quantum technology to support experimentalists worldwide.

We celebrate equality and diversity, welcoming talented individuals to make a real difference. Our active Diversity & Inclusion and Culture Committees enrich our workplace with a rich variety of backgrounds, cultures, perspectives, and skills.

Enough About Us, What About You?

• The Track Record: 7+ years in software engineering, with at least 2 years leading a team (formally or as a strong tech lead).
• Python Mastery: Deep Python expertise and a solid grasp of software design fundamentals (SOLID, design patterns).
• A “People‑First” Mindset: Enjoy seeing others succeed, running effective 1‑on‑1s, providing tough but fair feedback, and helping junior engineers level up.
• Architectural Vision: Navigate trade‑offs of compiler design, ASTs, or intermediate representations (IRs). Experience with LLVM or MLIR is a huge plus.
• Scientific Curiosity: Not requiring a PhD in Physics, but excited to learn. Experience with the quantum/scientific Python ecosystem (Qiskit, NumPy, SciPy) is a great head start.
