Contracted Embedded Systems Design Team

Executive Summary

Sonexos is seeking to engage an experienced embedded systems development partner to lead the design and delivery of a high-performance embedded platform for synchronized audio measurement and real-time DSP processing. This platform will be deployed within a Tier One customer environment and must meet rigorous standards for precision, reliability, and integration flexibility.

This is a contracted B2B engagement and not an employment opportunity. The selected partner will be responsible for end-to-end hardware and low-level software development aligned to a detailed specification provided by Sonexos, under NDA.

Scope of Work

The embedded platform is defined by a detailed technical specification and includes the following responsibilities:

Hardware Development

• Zynq 7100-based custom board design and integration
• Peripheral integration (USB 2.0, Ethernet, A2B, CAN FD, I3C, analog audio interfaces)
• Power management for automotive and portable operation, including battery regulation
• Touch panel integration via eDP
• Software and Firmware Development
• FreeRTOS on ARM Cortex-A9 cores
• Low-latency DSP task coordination with (optional) HiFi5 DSP cores
• Custom audio routing and synchronization using programmable logic (ADSE)
• Configuration and diagnostic interfaces (Ethernet, USB, UART, JSON-based schemas)

System Integration & Testing

• Validation of synchronized multi-channel I/O
• Support for deterministic DSP streaming and real-time test & measurement
• Deployment of test scripts and measurement modes in line with automotive standards

Required Expertise

• Proven experience with AMD/Xilinx Zynq SoCs, especially Zynq 7000 series
• Advanced knowledge of embedded audio and real-time DSP systems
• Familiarity with A2B and CAN FD networks, automotive-grade interface design
• Strong grasp of FreeRTOS, programmable logic, and multi-domain clock synchronization
• Demonstrated ability to design for automotive environments (vibration, EMI, power stability)
• Previous engagements in automotive, audio, or precision measurement applications

Engagement Details

• Start Date: Q3 2025
• Location: Remote, with optional on-site integration phases (Europe/Asia-partners preferred)
• Duration: ~12 months, with possible extension
• Commercial Terms: Negotiable, milestone-based
• Confidentiality: NDA required prior to disclosure of full specification
• Deliverables: Hardware schematics + layouts, firmware, test validation reports, and build documentation
