Dear,

We are looking for Embedded Software Engineer with USB/Bluetooth Audio.

Location - Gurgaon

Exp Range - 4 to 9 Yrs.

About the role

Develop firmware for an automotive Bluetooth audio connectivity device built on an ARM Cortex-M MCU and a Bluetooth audio SoC. Hires will be split between USB / MCU firmware and Bluetooth audio firmware, but everyone works across the stack.

What you will do

- Implement USB composite device firmware: USB Audio Class, HID and vendor-specific endpoints; low-latency DMA / I2S audio paths.
- Develop Bluetooth audio source functionality on a vendor SDK: A2DP / AVRCP, LE Audio (LC3), pairing and connection management, volume and metadata sync.
- Implement fail-protected firmware update (A/B images, rollback), power / thermal monitoring, diagnostics, fault logging.
- Debug with JTAG / SWD, logic analyzers, USB analyzers and Bluetooth sniffers; run headset interoperability testing.
- Work to automotive practices: MISRA C, static analysis,



unit and on-target tests, code review, CI.

What we are looking for

- 5 to 9 years embedded C on ARM Cortex-M.
- Hands-on experience in at least one of: USB device stacks (composite / UAC / HID / DFU) or Bluetooth audio firmware ( Infineon AIROC or similar).
- Working knowledge of Bluetooth Classic audio profiles and LE Audio concepts.
- Experience with DMA-driven audio / I2S pipelines, bootloaders, and firmware-update mechanisms.
- RTOS or bare-metal design, GCC toolchains, Git; Bachelor's / Master's in Electronics or Computer Engineering.

Nice to have

- Automotive background (MISRA, ASPICE); secure boot / signed images; audio DSP basics; Bluetooth SIG qualification.
