Essential Functions:

System Design & Documentation
• Lead the design, development, and testing of embedded systems, from initial concept through production.
• Create comprehensive project documentation, including system architecture, block diagrams, firmware state diagrams, and product descriptions in accordance with ISO standards and company policies.
• Perform feasibility studies, design and construct specialized test jigs/fixtures, and interface with suppliers as needed.

Hardware Design & Development
• Design and develop high-speed mixed-signal (analog and digital) circuits, including:
o Microprocessors, DSPs, FPGAs, memory, and clocking circuits.
o Communication interfaces such as Ethernet, UART, USB, I2S, I2C, and SPI.
o Analog and digital audio systems.
o Low-voltage switch-mode power supplies (SMPS).
• Perform circuit simulation using LTSpice or equivalent tools.
• Create complete schematic packages, including BOMs, layout instructions, and all necessary manufacturing files for PCBs and PCBAs.
• Apply best practices for high-speed PCB layout, design for EMC (EN55032, EN61000), design for safety (EN62368), and design for reliability (thermal management).

Firmware & Software Development
• Develop, test, and debug robust, real-time embedded firmware in C/C++ for microcontrollers and DSPs.
• Write low-level drivers and APIs for peripherals and communication protocols.
• Implement and optimize firmware to ensure seamless hardware/software integration and meet system performance requirements.
• Utilize version control systems (e.g., Git) for firmware development.

Integration, Testing & Validation
• Perform hands-on board bring-up and debug new hardware prototypes, identifying and resolving issues at the hardware-software interface.
• Assemble and modify electrical prototypes and systems using hand tools and measuring instruments to correct functional deviations.
• Set up and operate test equipment (oscilloscopes, logic analyzers, etc.) to evaluate system performance and validate designs against specifications.
• Verify second-source component compatibility through comprehensive testing.
• Document test procedures, specifications, and results.

Collaboration & Support
• Participate in hardware and firmware design reviews to ensure project goals, timelines, and budgets are met.
• Collaborate with mechanical, software, and manufacturing engineers to bring new products from concept to production.
• Provide technical assistance and problem resolution for engineering challenges encountered throughout the product lifecycle.
• Train technicians on technical aspects of new designs and products.

Essential Tasks:

• Provide support for customer problems/complaints.   This could be in-house, telephone, on site, etc.
• Collaborate with electrical engineers and other personnel to identify, define, and solve development problems.
• Analyze and interpret test information to resolve design-related problems.
• Prepare project cost and work-time estimates.
• Draw or modify diagrams and write engineering specifications to clarify design details and functional criteria of experimental            electronics units.
• Review the work of others within the team and coach as necessary. 
• Review existing electrical engineering criteria to identify necessary revisions, deletions, or amendments to outdated material.
• Plan method and sequence of operations for developing and testing experimental electronic and electrical equipment.
• Proficiency in the use of electronic test equipment, comprehensive understanding of electronic circuitry theory.
• Comprehensive understanding of mechanical PCB design for audio and power circuitry.
• Interface with internal and/or contract manufacturers to resolve any production or test issues.
