Applications Engineer - Hermetics

FOC Acquisitions; Sterling (MA); On-site; USD 90,000 - 130,000; Full time

Job summary

Connexis Group is seeking a skilled Applications Engineer for Hermetics to translate customer problems into viable, manufacturable fiber-optic solutions. You will work with Inside Sales and customer R&D teams to define requirements and move opportunities toward prototypes and production.

You will evaluate hermetic interfaces, propose configurations, and coordinate prototypes, tests, and qualification activities while balancing technical performance with manufacturability and cost.

Qualifications

• Bachelor’s degree in mechanical, electrical, materials or related engineering discipline, or equivalent practical experience.
• Technical experience with hermetic electrical feedthroughs, sealed connectors and headers, PCB seals and potted/hermetic assemblies, epoxy and/or glass-to-metal sealing technologies, electrical isolation and dielectric requirements, material compatibility and thermal expansion, fiber-optic feedthroughs, high-voltage and high-current feedthroughs, vacuum and pressure interfaces, leak-rate requirements and helium leak testing, temperature, pressure and environmental requirements, aerospace/defense, semiconductor, energy, cryogenic and industrial applications.
• Experience with hermetic packaging, electrical interconnects, vacuum systems, connectors, feedthroughs, sealing technologies or adjacent engineered components.
• Comfort communicating directly with customer engineers, R&D teams and technical decision-makers.
• Ability to make practical technical judgments in early-stage situations where requirements may be incomplete.
• Understanding of the relationship between design choices, manufacturing capability, cost and scalability.
• Strong written communication, organization and sense of urgency.
• Experience in aerospace/defense, semiconductor equipment, vacuum systems, energy, cryogenic or industrial applications is highly desirable.

Responsibilities

• Participate in customer discovery and technical meetings with the Inside Sales Lead.
• Understand the application, system interface, operating environment, pressure/vacuum conditions, electrical requirements, materials, geometry, volumes and qualification needs.
• Ask the technical questions required to determine fit and identify critical or missing requirements.
• Help customers translate early concepts or legacy designs into actionable requirements.
• Evaluate application fit across hermetic feedthroughs, connectors, headers, conductors, PCB seals and related sealed interfaces.
• Recommend preliminary product configurations, materials, sealing approaches and manufacturing methods.
• Evaluate factors such as voltage/current, insulation, leak rate, temperature, pressure, vacuum, material compatibility, thermal expansion and environmental exposure.
• Identify technical risks and coordinate more complex feasibility reviews with plant engineering, manufacturing and quality.
• Help convert technical discussions into complete, quotable requirements and RFQs.
• Develop or review technical assumptions supporting quotations and coordinate drawings, specifications or preliminary designs as required.
• Coordinate prototypes, samples and development builds and help establish technical success criteria.
• Support leak testing, electrical testing, environmental qualification, failure analysis and design iteration through production approval.
• Partner with the Inside Sales Lead throughout the opportunity lifecycle and participate in targeted customer and prospect discussions.
• Provide rapid technical responses that keep opportunities moving.
• Assist in overcoming technical objections during the quote-to-close process.
• Identify additional applications, programs and engineering contacts while engaging with customers.
• Work with manufacturing, quality and engineering to balance technical performance, manufacturability, cost and scalability.
• Document repeatable applications, technical solutions and design guidance.
• Help identify product-platform opportunities that can be reused across multiple customers and markets.
• Provide customer and market feedback to support new capability and process development.
