Principal FirmwareMiddleware Engineer

1. Architectural Definition & Design 

• Fabric Firmware Architecture: Architect and specify the low-level firmware running on internal microcontrollers within the UALink Switch ASIC. 

• Hardware-Software Co-Design: Collaborate heavily with ASIC design logic design (RTL) and verification teams to define hardware-software interfaces registers scratchpads and memory maps. 

• Protocol Implementation: Define the firmware stack to support UALink physical link and transport layers managing credits routing tables and flow control. 

2. Initialization Boot & Fabric Management 

• Link Initialization & Training: Design deterministic fast link-training state machines to bring up ultra-high-speed die-to-die and chassis-to-chassis UALink connections. 

• Topology Discovery & Routing: Architect efficient algorithms for runtime topology discovery dynamic routing and credit management to prevent fabric congestion. 

• Platform Orchestration: Lead the design of SDKs and APIs that expose switch functionality to baseboard management controllers (BMCs) using OpenBMC and Redfish APIs. 

3. Performance RAS & Security 

• Latency & Bandwidth Optimization: Fine-tune bare-metal execution paths to guarantee deterministic low latency for collective communication primitives (e.g. All-Reduce All-to-All). 

• Advanced RAS (Reliability Availability Serviceability): Design robust error-handling telemetry and fault-isolation micro-architectures (e.g. link degradation fallback FEC and error containment). 

• Security & Root of Trust: Implement secure boot cryptographic firmware authentication and runtime attestation to ensure fabric integrity. 

Qualifications :

Education & Experience 

• Degree: Bachelors or Masters/Ph.D. in Computer Engineering Electrical Engineering Computer Science or a related discipline. 

• Experience: 15 years of hands-on experience in embedded systems server platform architecture or low-level silicon firmware development. 

Technical Skill Set 

• Language Masteries: Expert-level proficiency in C for bare-metal and RTOS environments (e.g. ThreadX FreeRTOS Zephyr) and Python for hardware automation and modeling. 

• Protocol Expertise: Deep technical understanding of high-speed scale-up/scale-out interconnect protocols (UALink NVLink CXL or PCIe Gen5/Gen6). 

• Network Switching Concepts: Comprehensive knowledge of credit-based flow control packet routing physical layer (PHY) equalization and SerDes management. 

• Tooling: Strong familiarity with hardware debuggers (JTAG Lauterbach Lauterbach/TRACE32) and lab equipment (Oscilloscopes PCIe/Protocol Analyzers).
