Proficiency using standard electronic lab instrumentation and diagnostic equipment
Ability to perform precision component replacement and repair on PCB assemblies
Ability to read and interpret schematics, technical drawings, bills of material, and engineering documentation
Strong technical problem-solving skills with the ability to work independently and manage multiple priorities
Strong written and verbal communication skills
Ability to read, write, and communicate effectively in English
Ability to interpret technical documents, schematics, and written instructions
Ability to clearly document technical findings and communicate with cross-functional team members

Nice To Haves

Experience supporting prototype development within medical device, regulated manufacturing, or other high-reliability product development environments
Experience supporting failure analysis, component evaluation, and laboratory test setup activities
Familiarity with engineering change processes, technical documentation requirements, and quality-driven product development environments
Prior experience providing technical guidance or support to junior technicians

Responsibilities

Perform advanced troubleshooting, repair, testing, and validation of electronic assemblies, printed circuit boards, subassemblies, and prototype systems using schematics, technical documentation, and electronic test equipment.
Perform precision hand soldering and rework of surface-mount (SMT) and through-hole components, including micro-pitch devices such as QFN, QFP, BGA, and 0201/01005 passive components.
Use microscopes, magnifying tools and precision equipment to ensure accurate component placement and high-precision quality soldering results.
Build, modify, rework, and assemble electronic prototypes, cables, fixtures, and test setups to support engineering development and verification activities.
Conduct board-level diagnostics and failure analysis using oscilloscopes, multimeters, logic analyzers, signal generators, and other laboratory instrumentation.
Support prototype bring-up, debug activities, and engineering design modifications through component replacement, soldering, rework, and technical evaluation.
Interpret schematics, wiring diagrams, assembly drawings, bills of material, and engineering instructions to execute technical assignments accurately and efficiently.
Partner closely with engineers to support product development activities, including prototype builds, testing, troubleshooting, and issue resolution.
Assist with evaluation of components, materials, and assemblies during development and failure investigation activities.
Document technical observations, test results, prototype changes, and repair activities in accordance with engineering procedures and quality requirements.
Maintain laboratory equipment, tools, and workspaces to ensure safe, organized, and efficient operation of the electronics lab environment.
Identify opportunities to improve lab processes, test methods, fixture setup, and technician workflows to support efficiency and reliability.
Provide technical guidance and support to less experienced technicians as needed.
