Electrical Engineer III Communications

Electrical Engineer III – Communications (OTTO Engineering) Responsibilities 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. Qualifications 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. #J-18808-Ljbffr OTTO Engineering, Inc.
