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

You’ll be joining a small, senior team operating at the intersection of hardware, software, music, and AI, with a proven track record of shipping devices at scale and a significant installed user base.

The company is emerging from a period of stability, but with major next‑generation products planned for 2026, and this role will be central to shaping the technical direction and execution of those devices.
