About RMT
Resonance Micro Technologies (RMT) is an early-stage company pioneering wafer-scale production of high-performance micro-mirrors, micro-cavities, and precision micro-optics for the emerging quantum economy. As quantum computing, sensing, and precision timing move from laboratory demonstrations to deployed systems, demand is growing for manufacturable optical components that combine exceptional performance with scalable production. RMT's technology, developed through DARPA-supported research at Yale University, is designed to address this need by replacing hand-crafted optical manufacturing with robust wafer-scale processes for next-generation classical and quantum systems.
We are a small founding team at the beginning of this trajectory. This is an opportunity to join early, shape the company's technical direction, and help build a platform technology with meaningful impact across emerging photonics markets.
The Role
We are looking for a senior fabrication process engineer to take end-to-end ownership of our core microfabrication process. The role spans mastering the current research-grade process in our partner lab at Yale University, driving systematic process development and yield improvement, and leading transfer to external production and foundry partners. The position also offers opportunities to expand into laser spectroscopy, optical test and characterization, photonic system integration, and packaging.
By joining at this early stage, you will work closely with the co-founders to define the process roadmap, establish the process engineering function, and help build the team that will scale RMT's technology from lab demonstration to production readiness.
What You'll Do
- Take ownership of our core microfabrication process with a mandate to develop it from research-grade to production-ready.
- Define and execute a structured process development roadmap: design of experiments, metrology strategy, failure analysis, and yield improvement.
- Develop robust process flows and standard operating procedures that are transferable, reproducible, and auditable.
- Lead the transfer of mature processes to external production and foundry partners.
- Build and lead the process engineering team by recruiting, onboarding, and mentoring engineers and technicians.
- Develop and perform optical characterization and laser spectroscopy of fabricated devices, and drive feedback loops between characterization results and process development.
- Engage directly with customers and government program offices on technical requirements, capabilities, and process qualifications.
What We're Looking For (Required)
- Substantial hands-on experience in microfabrication and cleanroom processing, with a track record of owning a process from development through production transfer.
- Deep process development expertise in photolithography and reactive ion etching (RIE): recipe development, optimization, troubleshooting, and DOE-based process characterization.
- Demonstrated experience transferring lab-scale or pilot processes to external production or foundry partners.
- Experience building or leading a small fabrication or process engineering team.
- A rigorous, data-driven approach to process improvement and root-cause analysis.
- The ability to operate independently, prioritize effectively, and make sound technical decisions in a fast-moving early-stage environment.
Nice to Have
- Photonics background in free-space optics, integrated photonics, lasers, and Pound-Drever-Hall (PDH) locking.
- Experience with thin-film optical coating processes and low-loss optics.
- Wafer-level bonding and packaging experience.
- Experience engaging with defense or government program offices on process qualification or transition.
Education & Level
We are targeting candidates at the MS or PhD level, or engineers with equivalent depth of hands-on production process experience. Title, scope, and compensation will reflect experience, demonstrated capability, and the leadership expectations of this role.
Compensation & Equity
Salary range: $110,000 – $155,000 per year, commensurate with experience. Equity compensation is included and reflects the senior technical leadership scope of this position. RMT also offers a competitive benefits package; specific benefits and equity details will be discussed during the interview process.
Logistics & How to Apply
This is a full-time role based in New Haven, Connecticut, with regular on-site work expected due to the hands-on laboratory and manufacturing nature of the position. Some travel may be required to support foundry partners, customers, suppliers, or government program activities. Reporting structure, relocation support, and final title will be discussed with candidates during the interview process.
This position may require access to technology or technical data subject to U.S. export control regulations, including the International Traffic in Arms Regulations (ITAR) and the Export Administration Regulations (EAR). Employment will be conditioned, as applicable, on the candidate's ability to access such technology or technical data in compliance with U.S. law.
To apply, please email your resume to careers@resonancemicro.com. Candidates are welcome to include a brief note describing relevant cleanroom, microfabrication, process transfer, photonics, or team-building experience.
