Technical Lead – Embedded Systems & PCIe

Location – Bangalore / Pune / Kolkata / Indore

We are looking for a hands-on Technical Lead / Architect to drive PCIe and CXL engineering for AI infrastructure: accelerators, NVMe SSDs, retimers, PCIe switches and AI server platforms. You will own host-side drivers or device-side firmware, link bring-up, debug and validation on customer programs, write and debug code yourself, and lead a team of engineers.

Key Responsibilities

• Develop and debug PCIe/CXL host drivers in the Linux kernel, or device-side endpoint firmware (bare-metal or RTOS on ARM/RISC-V cores).
• Bring up PCIe Gen5/Gen6 links on new platforms: link training (LTSSM), equalization, enumeration, BAR and resource allocation, MSI-X and DMA.
• Root-cause link, error (AER/DPC), hot-plug and performance issues across hardware, firmware and OS layers.
• Build and run PCIe/CXL validation: compliance, interoperability, stress, error injection and telemetry, automated in Python.
• Integrate accelerators, NVMe SSDs, SmartNICs/DPUs, PCIe switches and retimers into AI server platforms.
• Work directly with customer silicon, hardware and validation teams; lead design reviews and technical customer discussions.
• Own technical delivery for the team and mentor engineers.

Qualifications

Education

• Bachelor’s or master’s degree in computer engineering or computer science, Electronics, Electrical, (or equivalent experience).

Experience

• 8 to 14 years in embedded systems software.
• At least 4 years of hands-on PCIe work on a shipped product or silicon program.

Must-Have Technical Skills

• Strong C programming, with hands-on coding.
• PCIe protocol depth: TLP/DLLP, LTSSM, configuration space, BARs, MSI/MSI-X, AER.
• Either Linux kernel PCIe driver development or firmware development for a PCIe device/endpoint.
• Lab debug with PCIe protocol analyzers/exercisers, JTAG, and kernel or firmware traces.
• Python for test automation.

Good-to-Have Technical Skills

• CXL 2.0/3.x (CXL.io, CXL.mem), memory expansion and pooling.
• PCIe Gen6 (PAM4, FLIT mode), retimers and PCIe switches.
• NVMe, SR-IOV, IOMMU/ATS, peer-to-peer DMA, GPUDirect.
• Server platform PCIe: UEFI/BIOS initialization, ACPI, BMC/OpenBMC.
• PCI-SIG or CXL compliance testing.
• GPU or custom AI accelerator integration.
