Lightsynq Technologies Inc Optics and packaging engineer Brighton, MA · Full time Company website

Apply for Optics and packaging engineer

Position Background:

Lightsynq is a deep-tech startup focused on building quantum interconnects capable of linking quantum systems. For example, these interconnects enable distributed, modular architectures for quantum computers, allowing them to surpass scaling limitations inherent in monolithic approaches. Our approach uses quantum memories based on color centers in diamond, a technology with critical enabling capabilities such as heralding and in-memory computing. Crucially, Lightsynq’s interconnects do not require disruptive redesigns of existing quantum hardware. They are designed to be compatible with quantum devices across various platforms, from atoms, ions, and photons to superconducting circuits with optical interfaces. This allows us to accelerate the quantum industry's timeline to commercial impact without having to pick a winning approach while the race is still heating up.

To support this effort, Lightsynq has developed a number of key enabling components, one of which is low-loss optical fiber-to-chip packaging that is compatible with cryogenic environments and other challenging conditions. Lightsynq is hiring an optics and packaging engineer to accelerate deployment of this technology, for both our internal efforts and to help provide this enabling capability to the quantum and classical photonics communities.

Responsibilities

In this job you will work with a leading team of quantum optics and photonics experts to package and deploy novel integrated photonic devices in cryogenic environments. You will:

• Build on Lightsynq’s established process to standardize, test, and optimize tools and techniques for low-loss, cryo-compatible optical packaging to help bring this capability to customers across industry, the public sector, and academia.
• Develop processes and metrics to evaluate and monitor process yields and bottlenecks.
• Collaborate with research and business development teams to develop new packaging capabilities and mature them into standard processes.

What we are looking for:

• Bachelors degree in engineering, physics, optics, or related field + 3 years of industry experience developing and deploying photonic devices in an industry setting or a PhD in engineering, physics, optics, or related field.
• Hands on experience performing nanofabrication or optical packaging tasks
• Hands on experience working with fiber optics or integrated photonic devices
• Experience using CAD software to develop hardware prototypes and systems

You'd be a great fit with:

• Bachelors degree in engineering, physics, optics or related field + 5 years of industry experience developing and deploying photonic devices in an industry setting or a PhD in engineering, physics, optics, or related field + 2 years of industry experience developing and deploying photonic devices in an industry setting. Experience working in OSAT (Outsourced Semiconductor Assembly & Test) or adjacent industry a plus.
• Hands on experience with fiber packaging, packaging process development, photonic design, high precision fiber alignment, or optical adhesive dispensing.
• Demonstrated track record of testing and deploying novel integrated photonic devices in cryogenic or otherwise exotic environments

A Note on Qualifications:

We know that no candidate will tick every box perfectly—and we value potential, creativity, and diverse experiences over a perfect checklist. If you’re excited about our quantum interconnect technology and feel that you bring many, even if not all, of the qualifications, we encourage you to apply.

Benefits:

• Lightsynq offers a variety of benefits, including competitive compensation, healthcare, dental, and vision insurance, retirement plan, as well as paid time off.
