Roaming Manager Jobs in California (NOW HIRING)

Job Summary:
Nile is a company that delivers Connectivity as a Service for enterprise campuses, focusing on improving the reliability of their access point platform. The Wireless Reliability Engineer will be responsible for ensuring the reliability of the platform through automation, validation, and chaos engineering, primarily in pre-production environments.
Responsibilities:
• Design and evolve the automation, validation, and chaos frameworks that exercise our APs in CI/CD and in the lab.
• Drive deep L1–L7 investigations when complex wireless issues appear and convert those learnings into durable tests and platform changes.
• Partner closely with firmware, cloud SRE, and security to ensure reliability is engineered in, not bolted on.
• Architect Python-based automation scripts that integrate into CI/CD to validate AP firmware, drivers, and wireless features at scale.
• Continuously increase automated coverage of functional, performance, and longevity tests for Wi‑Fi features (11ax/11be), roaming, QoS, and management-plane behavior.
• Define test strategy and guardrails: what must be covered on every change, on nightly runs, and on long‑running stress suites.
• Design and run chaos and stress scenarios against Wi‑Fi and datapath stacks: RF impairments, load patterns, roaming storms, congestion, and failure injections.
• Characterize and harden the system under realistic client and traffic mixes using tools like IxChariot/IxANVL, Spirent, or Alethea (or equivalent).
• Turn intermittent or “rare” failures into reproducible automated tests that block regressions.
• Validate 802.1X, WPA3, and Zero Trust campus behavior, including onboarding flows, policy enforcement, and failure/attack scenarios.
• Work with security engineering to translate threat models into repeatable test plans and automation (e.g., auth storms, misbehaving supplicants, rogue AP/client scenarios).
• Use silicon‑level telemetry and debug hooks on Qualcomm (or similar) AP SoCs to understand RF performance, power, and error behavior under load.
• Collaborate with silicon/firmware teams to correlate lab findings with driver/firmware changes and influence roadmap and design decisions.
• Lead deep technical investigations across L1–L7 when Nile or customer scenarios expose weird or hard‑to‑reproduce behavior.
• Produce clear RCAs that tie symptoms to root cause and result in concrete fixes in firmware, cloud controllers, or test systems.
• Feed every critical RCA back into automation, metrics, or specifications so the same class of issue does not recur.
• Work day‑to‑day with AP firmware, wireless systems, cloud SRE, security, and product teams.
• Engage with selected high‑severity production incidents when deep wireless expertise is needed and then codify those learnings back into tests.
Qualifications:
Required:
• Experience: ~5+ years in one or more of: wireless systems engineering, AP or client firmware validation, Wi‑Fi performance/reliability, or SRE for networking systems.
• Wireless proficiency: Hands‑on work with 802.11ac/ax (11ax required; 11be familiarity a plus).
• Comfortable reading and interpreting packet captures (e.g., Wireshark) and RF measurements; you know what a “clean” RF environment looks like and how to recognize common impairments.
• Strong Python skills building test frameworks, harnesses, or tooling (not just one‑off scripts).
• Experience integrating tests into CI/CD pipelines (GitLab CI, Jenkins, etc.).
• Proven track record debugging complex multi‑component systems (AP + clients + backbone + cloud).
• Ability to design experiments, isolate variables, and turn qualitative “it seems flaky” reports into measurable hypotheses.
• Working knowledge of 802.1X, EAP, WPA2/WPA3, and robust onboarding flows.
• Comfort validating security behavior (e.g., PMF, key management, misconfigurations, and downgrade/failure scenarios).
Preferred:
• Deep familiarity with 11be/EHT, OFDMA, MU‑MIMO, and multi‑band/multi‑link operation.
• Handson experience with Qualcomm or similar Wi‑Fi SoC platforms and corresponding debug/telemetry interfaces.
• Experience with one or more Wi‑Fi test tools/stacks: Ixia, IxChariot, IxANVL, Spirent, Alethea, or similar.
• RF impairers, channel emulators, or shielded chambers.
• Prior work in SRE‑style roles for networking/wireless services: SLIs/SLOs, error budgets, on‑call, and incident management.
• Experience using AI‑assisted development tools (Cursor, Copilot, etc.) as part of your daily workflow.
