About Qunnect

Qunnect is a dynamic, venture-backed startup in the heart of Brooklyn, NY. We build and deploy first-in-class hardware to transform existing telecommunication fiber infrastructure into quantum-secure networks for defense, intelligence, financial services, healthcare, and critical infrastructure.

Role Description

We're hiring a Characterization Engineer to take ownership of the end-to-end qualification process for our quantum devices. This role is ideal for someone with hands-on experience in quantum optics who thrives on precision testing, building robust experimental setups, and bridging the gap between R&D and product deployment. At Qunnect, our systems combine optics, atomic physics, and electronics. In this role, you’ll work at the intersection of these disciplines, collaborating closely with both our manufacturing and science teams to ensure every device meets the rigorous performance and quality standards demanded by real-world quantum networks.

This is an in-person role. As part of the role, you directly support installations and testing at select customer sites through occasional travel. You’ll help deploy Qunnect’s technologies into the global market with our specialized team turning quantum networking into a practical, deployed reality.

Tasks

• Lead the implementation of quality assurance/control processes of assembled optical devices
• Design and operate test setups for quantum devices
• Qualify new builds coming off our assembly line before deployment
• Develop and refine performance specs for each product line
• Create test procedures, automation scripts, and data analysis pipelines
• Identify performance drifts, degradation, or failure modes in both lab and deployed units
• Collaborate with hardware/software/manufacturing teams in product reviews to close loop between test results and production improvements
• Assist installation and service field engineering teams at customer sites.

Qualifications

• Detail oriented with strong clerical and organizational skills
• Strong mechanical aptitude and assembly skills
• Be a self-starter, who will work independently on a variety of daily tasks
• Openness to cross-training within the department to learn other skills and work processes
• Hands-on lab experience working with optics, quantum light sources, single-photon detectors, or time-tagging systems
• Experience with test instrumentation
• Comfort scripting in Python for data analysis and test automation
• Clear thinker, organized experimenter, and someone who gets satisfaction from proving something works, every time.

Preferred Qualifications

• M.Sc. (Ph.D. optional) in experimental AMO/Quantum optics, or related field.

Salary Range: $100,000-125,000, commensurate with experience.

Please note that we do not expect candidates to possess all the above qualifications, we are willing to train!

At Qunnect, we offer a stimulating and collaborative work environment, competitive compensation, and the opportunity to be at the forefront of networking innovation.
