Overview

TalentEdge Technology are looking to hire a Senior Embedded Engineering Leader to take ownership of the firmware stack for a next-generation, AI-enhanced connected music hardware platform.

This role is hands-on and deeply technical, suited to an engineer who enjoys working across the full embedded stack, from low-level hardware bring-up through to cloud-connected features and who places a premium on robustness and real-world reliability.

What You’ll Be Working On:

• Ownership and evolution of the embedded firmware stack for connected consumer hardware
• Firmware development in C/C++ on NXP i.MX RT (480MHz Cortex-M7) platforms
• Design and implementation of critical systems, including Over-the-air update infrastructure, Bluetooth audio (A2DP / AVRCP), Wi-Fi connectivity and device provisioning, Bootloaders and persistent state management, Audio DSP integration
• Ensuring production-grade stability, performance, and fault tolerance
• Close collaboration with mobile, web, backend, and hardware teams to deliver cohesive end-to-end experiences
• Supporting device certification and production readiness, including FCC / CE compliance
• Providing technical leadership, architectural direction, and high-quality code review within the embedded domain

What We’re Looking For:

Essential experience:

• Senior-level embedded firmware experience, ideally in consumer electronics (Audio would be even better)
• Strong C & C++ skills on resource-constrained systems
• Experience with FreeRTOS or comparable RTOS environments
• Hands-on work with Bluetooth and Wi-Fi stacks
• Familiarity with embedded build systems such as CMake
• A strong engineering mindset around reliability, resilience, and real-world failure modes

Desirable experience:

• Audio, DSP, or media-related systems is HUGELY desirable
• Shipping hardware products at scale
• OTA update systems and secure firmware pipelines
• Certification processes (FCC, CE, or similar)

Why This Role
