Job description

About Qunnect:

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

Job Description:

As a Software Engineer at Qunnect, you'll play a crucial role in developing software solutions that enable the operation and optimization of quantum networking systems. You'll collaborate closely with our team of physicists and hardware engineers to develop early-stage products into industry-grade quantum networking devices, integrating them into our software control plane. You will help build, operate, and monitor reliable, metropolitan-scale quantum networks on fiber testbeds worldwide—including our own in New York City—and support deployment of our networking suite at customer and partner facilities.

This is a full-time, on-site, mid-level role in a fast-paced and multidisciplinary R&D setting.

Key Responsibilities:

• Design and develop production-quality software for managing and monitoring quantum networking systems and devices.
• Build and operate distributed systems that coordinate networked devices across multiple sites, including telemetry pipelines, event-driven messaging, and state synchronization.
• Maintain and evolve internal tooling, CI/CD pipelines, and test infrastructure to support high-quality, maintainable software.
• Deploy, maintain, and support software systems used by internal teams and external customers operating these devices.
• Collaborate closely with physicists, hardware engineers, and manufacturing teams on R&D across multiple product lifecycles.
• Help improve system reliability, observability, and performance across our software stack.

Required Qualifications:

• Bachelor's or Master's degree in Computer Science or a related field.
• 3+ years of full stack software engineering experience.
• Strong proficiency in Python and modern web technologies (JS/React).
• Experience in building features end to end: iterate on the specs, define the data model, design and implement the backend APIs, build the frontend components.
• Understanding of DevOps best practices and CI/CD pipelines.
• Strong communication skills and a collaborative mindset.
• Familiarity with Linux development environments, Git, and modern software development workflows.
• Proficiency in leveraging modern digital tools to streamline workflows.

Preferred Qualifications:

• Experience building user-facing web applications with authentication, authorization, and role-based access control.
• Experience with data analysis for evaluating system performance, experimental results, or operational metrics.
• Familiarity with networking protocols, networked applications, and cybersecurity best practices.
• Experience with containerization (Docker, Kubernetes, or similar).
• Experience applying machine learning techniques to operational data, time-series forecasting, or anomaly detection.

Job Type:

Full-time

Compensation:

$130k - $175k per year
