About the Team and RoleeBay's Site Network Engineering team designs and engineers the production fabrics connecting eBay's server fleet across data centers, POPs, and other properties. We run 100% SONiC-based open networking in production across six switch vendor families on multiple merchant silicon families. Zero availability-impacting fabric incidents every year since the SONiC transition began.You will establish SONiC platform engineering as an in-house function — this is a greenfield mandate, not a backfill. You own the full stack from ASIC layer through production deployment, with direct influence on architecture, release quality, and vendor strategy. A near-term goal is converging to a single SONiC release across all six vendor families; this role is central to that.What You'll Do- Drive end-to-end platform enablement for new switch hardware (transceivers/CMIS, optics qualification and tuning, thermal/PSU/fan/watchdog/sensors, EEPROM, LED/CPLD/FPGA as required).
- Lead ASIC SDK + SAI integration: vendor SDK integration/customization, SAI behavior tuning/modeling, syncd adaptations, dataplane correctness, performance, and stability.
- Design production reliability across the stack: warm/fast reboot correctness, upgrade safety, and high availability under load (hitless patterns where applicable).
- Debug and resolve complex issues across kernel/drivers → SDK/firmware → SONiC services (SWSS/orchagent, Redis DBs, containers), with strong bias for reproducibility and root-cause closure.
- Deliver features on real hardware and meet scale/performance targets (buffers/QoS/queues/counters/telemetry, link/port behavior, failure handling).
- Define and operationalize release processes: gating, rollback strategy, known-issue management, and production-readiness standards.
- Serve as key technical interface with ASIC vendors and ODMs, driving escalations and influencing outcomes.
- Build CI/CD pipelines, automated testing (PTF, SpyTest or equivalent), hardware-in-the-loop validation, and regression coverage.
- Contribute to upstream SONiC when appropriate and define a responsible fork/upstream strategy.
- Mentor peers and contribute to team growth as we scale (people management not required).
- Enable or materially stabilize at least one ASIC/platform family with measurable improvements (reboot reliability, crash rate, performance baselines, scale targets).
- Deliver a repeatable ASIC SDK integration + qualification pipeline.
- Establish foundational processes (testing, CI/CD, release discipline, vendor engagement) so the capability scales smoothly.
- Strong Linux systems software development background with C/C++ and expert debugging skills (gdb, perf, strace, core dumps).
- Production experience programming switching ASICs via vendor SDKs and/or SAI — including integration, behavioral tuning, and performance/stability troubleshooting.
- Delivered SDK/SAI-based switching features on real hardware in a production or production-like environment.
- Working knowledge of SONiC internals or equivalent NOS (SAI/syncd, SWSS/orchagent, Redis DBs, container model) with ability to ramp quickly.
- Ability to lead ambiguous technical initiatives and drive cross-functional delivery across sites/time zones.
- Track record partnering with merchant silicon vendors, including escalation management and influencing outcomes.
- Direct upstream contributions to SONiC, SAI, FRR, or Linux kernel networking.
- Deep SAI behavioral expertise (ACL, QoS, buffers, ECMP, counters, telemetry).
- Optics qualification, tuning, and vendor-specific behavior across transceiver families.
