Are you ready to play a key role in shaping the digital foundation of next-generation quantum photonic hardware?

At Sparrow Quantum we are dedicated to pushing the boundaries of light-matter interfaces for quantum technology by becoming the world’s leading supplier of state-of-the-art photonic quantum chip technology.

To support our advanced production and R&D efforts, we’re taking automation, control, data acquisition, and analysis to the next level. We’re looking for a talented Senior Embedded Software Developer to lead this journey and become a key driver in implementing state-of-the-art automation and control across our R&D lab facilities and the quantum photonic modules we develop.

The ideal candidate will bring experience in embedded software development, hardware interfacing, system control, and/or mathematical optimisation, and is motivated by solving real-world challenges through elegant, high-performance engineering.

What you'll do:

• Lead the development of software for automation, real-time control, and data gathering across Sparrow Quantum in collaboration with our R&D and production teams.
• Implement optimisation algorithm for stabilisation with motion control and signal processing using real-time detector feedback.
• Develop robust software architectures and user interfaces for integrating photonic chips with full-system equipment.
• Setting up an ecosystem around software development, hardware automation, and controls, including development roadmap and incorporations of best practices across the company.

In brief, we offer a unique opportunity for a talented senior software developer to collaborate with world-leading professionals in the field of quantum photonics.

What we're looking for

• Ph.D. or MS degree in a relevant field.
• Programming languages: Python, C-suite(C/C++), Rust (optional).
• Strong results as software/numerical lead of successful (scientific) hardware/software projects.
• Experience with real-time optimisation algorithms, signal processing, and detector feedback systems.
• Software architecture and experience with Digital Twin modeling and AI integration for predictive system behaviour and optimisation.
• Knowledge of photonics, electronics, solid state, and laser physics is a strong advantage.

Additionally, we expect you to thrive in a collaborative work environment and are inspired by the chance to contribute to groundbreaking advancements in quantum computing and information exchange. It's essential that the opportunity to develop quantum technology for commercial purposes

align with your professional aspirations.

Who you are

• Adaptability: You can thrive in a fast-paced, ever-changing work environment and are willing to learn new skills and approaches. As a member of our flock of Sparrows, you'll have the opportunity to work across various fields, including materials, photonics, and quantum, which will keep your work diverse and engaging.

• Creativity: You can think outside the box and generate innovative ideas and solutions.

• End-user focus: You can understand and anticipate end-user needs and deliver solutions that exceed their expectations.

• Self-starting team player: You can be a great collaborator in a team setting but also have the initiative and motivation to take on tasks independently.

About Sparrow Quantum

SparrowQuantum is a Danish quantum technology company dedicated to advancing light-matter interfaces for quantum technologies. The company is widely recognised as a leader in single-photon sources, demonstrating the world's highest light-matter coupling efficiency.

Our first product is an on-chip single-photon source with unparalleled specs; it provides long strings of more than 100 single photons of near-unity quality and a coupling efficiency higher than 98%, leading to more than 20 million high-quality single photons per second in an optical fiber that the customer can directly deploy for, e.g., multi-photon quantum simulations or quantum key distribution experiments.  

We work with GaAS/InAS quantum dots embedded in planar structures and operated at cryogenic temperatures. This unique and patented technology results from over two decades of pioneering research by founder Peter Lodahl and his HybridQuantum Networks Hy-Q Center of Excellence at the prestigious Niels BohrInstitute (NBI) in Copenhagen, Denmark
