Head of Software Development

Permanent employee, Full-time · Delft

Your mission
Our Mission

Qblox is a deep tech scaleup whose mission it is to accelerate our customers in the worldwide race towards building scalable quantum computers by providing them with the world's best quantum control stacks.

Qblox develops control stacks that combine unrivaled noise and drift performance, a low-latency arbitrary control flow and scalability up to 1000s of qubits. The control stack generates the analog pulses (DC to 18 GHz) needed for the control and readout of qubits. These analog signals are generated from 1000s of parallel channels and driven by our proprietary sequence processor technology. Our products are used by R&D teams globally to accelerate the development of operational quantum computers and quantum networks. The technology we are developing is compatible with a broad range of qubit technologies (superconducting, spin, NV-centres, cold atoms).

To control so many qubits, we developed a modular system that can be synchronized. This system is packed with high-end FPGAss that are synchronized with nanosecond precision, high-speed digital interfaces to multi-gigasample dataconverters and ultra low-noise and low drift analog (RF) circuits. The FPGAs contain among other things our proprietary sequence processors that generate the pulses to control the quantum hardware.

To interface with our equipment, we develop a software stack consisting of low-level drivers, compilers and assemblers written in C/C++ and higher-level tools written in Python. The current software department consists of around 20 engineers divided into three teams; Embedded Software, Application Software (Quantify) and the Test & Automation team. In the coming years, we aim to significantly grow the department to focus on the development of new software products.

Your Mission

As the Head of Software, you will take charge of building the department that is executing our software roadmap, ensuring that our development efforts align with our company's strategic objectives. As a key leader within our R&D organization, you will be responsible for the entire software development lifecycle, ensuring that our products are not only delivered fast and efficiently but also have performance that exceeds industry standards. Next to this, you will lead the Test & Automation team, which is responsible for building the infrastructure needed to effectively test our products. Your daily tasks will involve managing the software department's teams, budget, and implementing process improvements in alignment with the teams that allow our organization to grow further.

In this position, collaboration will be key as you work closely with other department heads and your team to coordinate activities and foster synergy across teams.

As part of your responsibilities, you'll have the opportunity to expand our software department by establishing new teams and nurturing existing ones. Your leadership will be instrumental in defining and implementing engineering processes to drive efficiency and innovation. You have strong people management skills, with the ability to create a working environment in which team members feel challenged, motivated, and develop and grow further. You lead by example, giving people the feeling and freedom to take ownership and accountability. You have a growth mindset that can adapt easily to our dynamic and fast growing company and you help the people in your department do the same. You are used to working with Agile frameworks and have experience in leading Agile transformation.

Moreover, you'll have responsibility for the department's budget, requiring strategic financial management to support our objectives effectively.

Reporting directly to the CTO, you'll play a pivotal role in shaping our company's technological vision and driving us towards continued success in the market. If you're ready to lead, innovate, and make a significant impact, we invite you to join us on this exciting journey.
