Primary Duties & Responsibilities

• Drive the electrical architecture of system circuit boards to meet customer specifications.
• Lead the design of high-density multi-layer PCBAs from initial concept to completion.
• Execute circuit designs that utilize a high degree of E/O and O/E functions.
• Create schematic drawings/BOMs and monitor PCB layouts.
• Perform electrical simulations and power analysis.
• Support customer reviews required to pass design development gates.
• Execute the integration of electronics, FPGAs and software/firmware supporting all phases of testing.
• Develop test specifications and bring up work instructions for designs
• Work with circuit layout subcontractors and board population subcontractors
• Collaborate with cross-functional teams consisting of optical, mechanical and system engineers.
• Participates in writing proposals, providing cost and schedule estimates in support of new business.
• Provide technical advice to less experienced electrical engineers.
• Oversee work assignments across a small team of hardware engineers.

Education & Experience

• Bachelor’s degree in electrical/electronic engineering with 15 years of circuit design experience or Master’s degree with 12 years' experience, or Ph.D. with 9 years' experience

Skills

• Proven expertise in designing high density multi-layer PCBAs. 
• Strong RF fundamentals and analog circuit design skills required.
• Strong background in circuit theory, control loops, high-speed DACs/ADCs, and mixed-signal design. 
• Design experience with switching power supplies, TEC controllers, laser diode drivers and photodetectors strongly desired.
• Experience with programmable logic devices and control system circuit design.
• Background in RF signal processing and/or optical fiber system design.
• Experience with RF circuit board design for isolation with high-speed small signals and decoupling of high-speed digital lines for A/D and D/A circuits.
• Mixed Signal and matched 50/100 ohm microstrip and strip line design practice. 
• Experience managing noise, jitter, crosstalk, signal integrity on PCB designs.
• Knowledge of circuit board thermal and EMI management.
• Use of schematic capture tools (Altium, Orcad) and simulators
• Familiar with PCB layout browsers (Altium, PADS, Xpedition).
• Experience with government defense design processes.
• Self-motivated, responsible, team player with leadership experience.
