Electrical Engineer III Communications

Electrical Engineer III – Communications (OTTO Engineering)

• Lead full‑cycle development, driving design, bring‑up, HW/SW integration, factory support, validation, and customer support.
• Own component selection, specifying and evaluating components for performance, reliability, and manufacturability.
• Design digital systems, architect interface logic, sensors, peripherals, microprocessors, memory, and connectivity.
• Develop audio circuitry, working with A/D and D/A converters, audio power amps, op‑amps, and signal‑chain components.
• Engineer advanced analog circuits: filters, FETs, linear/switch‑mode power supplies, battery monitoring, and charging.
• Validate product performance through test, analysis, and documentation to meet customer and regulatory requirements.
• Support existing products by implementing updates, troubleshooting issues, and assisting factory and field teams.
• Create production‑ready documentation: schematics (Altium), BOMs, ECNs, test plans, and specifications.
• Guide PCB design, providing direction on routing, high‑speed interfaces, impedance control, power distribution, and EMC compliance.
• Perform hands‑on troubleshooting using oscilloscopes, DMMs, and lab equipment.
• Define and execute testing: performance, reliability, EMC, and failure‑analysis.
• Establish production test requirements: board‑level and end‑of‑line test strategies and equipment selection.
• Collaborate cross‑functionally with Sales, Quality, Mechanical, Firmware, and Manufacturing Engineering.
• Drive design reviews, participate in DFMEAs to ensure robust, high‑quality designs.
• Ensure regulatory compliance by coordinating with test labs and agencies.
• Support project planning, defining timelines and ensuring adherence to schedules.
• Take on evolving challenges, contributing to additional engineering tasks as projects grow and shift.

• Experience with digital, analog, and audio circuit design.
• Proficiency in interfaces such as SDIO, IC, SPI, RS‑232, UART, JTAG, and serial/parallel connections.
• Knowledge of GPS, accelerometers, IMUs, speakers, microphones.
• Familiarity with Bluetooth, USB, and related protocols.
• Experience with schematic/layout tools;
  Altium preferred.
• Strong technical depth, initiative, and ability to work independently or in a team with minimal supervision.
