JJA.CO; Atlanta (GA); Hybrid; USD 140,000 - 200,000; Full time

Job summary

JJA.CO in Atlanta, GA is seeking a lead hardware engineer to own hardware across our underground wireless IoT devices. This hands-on leader will drive from requirements, through schematic and layout, to bring-up and mass production, while shaping system-level firmware architecture.

You'll work with an international hardware partner and our contract manufacturer, inherit a UK-based team, and grow a U.S. devices team to 3–5 engineers over the next year, ensuring rugged operation in harsh

Qualifications

• 7-10+ years of hands-on hardware design experience in Altium or equivalent, including board bring-up firmware.

Responsibilities

• Review schematic capture, PCB layout, component selection, thermal design and ruggedization for new designs and revisions
• Lead hardware bring-up, debug and validation through EVT/DVT/PVT
• Own the development-to-manufacturing handoff, through NPI and production line qualification at our contract manufacturer
• Manage outsourced mechanical and enclosure design partners
• Work with product management to define hardware, firmware and system-level requirements for new underground wireless IoT products
• Turn product and business requirements into architecture decisions that balance cost, power budget, reliability and ruggedization
• Work with the cloud software team on how devices send data, raise alarms and present data
• Evaluate RTOS-vs-bare-metal trade-offs for each device family based on power, reliability and startup-time requirements
• Guide firmware architecture for code reuse and portability, including MCU family selection, peripheral sets and pinout conventions across product families
• Review firmware at the hardware/firmware boundary: bootloaders, low-level drivers, power management and state machines, and timing-critical paths
• Set power budgets and startup reliability targets for battery-backed devices that wake, measure, sleep and alarm asynchronously
• Help set up the system-level test strategy and infrastructure for functional, environmental, reliability and end-to-end testing
• Provide L3/L4 technical support to the customer delivery team on field deployments
• Lead the hardware function technically and help guide firmware decisions with firmware engineering
