Applications Engineer - Fiber Optics

FOC Acquisitions•Sterling, MA
•$95,000 - $105,000

About The Position

Connexis Group is seeking an Applications Engineer specializing in fiber optics. This customer-facing technical-commercial role converts customer problems and early-stage opportunities into technically viable, manufacturable, and commercially attractive fiber-optic solutions. Working alongside the Inside Sales team, the engineer engages with customer engineering and R&D teams to understand applications, define requirements, assess feasibility, and move opportunities toward prototype, RFQ, qualification, and production. The role serves as a technical bridge between customers and internal engineering and manufacturing teams.

Requirements

  • Bachelor’s degree in engineering, physics, optics, photonics, or a related technical discipline, or equivalent practical experience.
  • Technical experience with optical fibers and fiber assemblies; fused fiber bundles and light guides; illumination systems and optical coupling; optical power handling; laser- and LED-based systems; numerical aperture, wavelength, and transmission; medical-device illumination and imaging; sensors, spectroscopy, and semiconductor optical systems; industrial photonics; and optical component integration.
  • Ability to communicate directly with customer engineers, R&D teams, and technical decision-makers.
  • Ability to make practical technical judgments in early-stage situations with incomplete requirements.
  • Understanding of the relationship between design choices, manufacturing capability, cost, and scalability.
  • Strong written communication, organization, and sense of urgency.

Nice To Haves

  • Experience in medical devices, semiconductor equipment, sensing, spectroscopy, industrial optics, or similar markets is highly desirable.

Responsibilities

  • Participate in customer discovery and technical meetings with the Inside Sales Lead.
  • Understand customer applications, system architecture, performance requirements, environmental conditions, interfaces, volumes, and qualification requirements.
  • Ask technical questions to determine whether opportunities fit current or adjacent capabilities.
  • Help customers turn early concepts or incomplete specifications into actionable technical requirements.
  • Evaluate technical fit and identify applicable products, fiber types, optical configurations, and manufacturing platforms.
  • Recommend preliminary technical approaches and identify customization or development needs.
  • Evaluate optical performance considerations, including wavelength, numerical aperture, transmission, coupling, geometry, power handling, and environmental requirements.
  • Identify technical risks and missing information, coordinating complex reviews with plant engineering and operations.
  • Convert technical discussions into complete, quotable requirements and RFQs.
  • Develop or review technical assumptions supporting quotations and coordinate drawings, specifications, or preliminary designs as needed.
  • Coordinate prototypes, samples, and development builds, and help establish technical success criteria.
  • Support testing, qualification, failure analysis, and iterative design adjustments through production approval.
  • Partner with the Inside Sales Lead throughout the opportunity lifecycle and participate in targeted customer and prospect discussions.
  • Provide timely technical responses to maintain commercial momentum and help overcome 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 performance, manufacturability, cost, and scalability.
  • Document repeatable applications, technical solutions, lessons learned, and reference designs.
  • Identify product-platform opportunities that can be leveraged across multiple customers and markets.
  • Provide customer and market feedback to inform product and process development.
