Wireless Network Engineer (Technology Specialist I) Digital and Technology Partners - Onsite

This is onsite 100% - 5 days a week

Location: Mount Sinai Hospital - 1468 Madison Ave

We are hiring a hands-on Wireless Network Engineer who can build and support enterprise wireless networks end to end. This is not a passive monitoring role and not a paper-design role. The right candidate has configured wireless controllers from scratch, deployed and tuned access points in real environments, troubleshoot client/device issues down to the RF and packet level, and used Ekahau to design, validate, and defend wireless designs in complex spaces.

• Configure and support Cisco wireless environments from the ground up, including controller setup, WLANs, policy mapping, tags/profiles, AP onboarding, and site deployment.
• Troubleshoot production wireless issues across the full stack: controller, AP, RF, authentication, DHCP, DNS, VLANs, switching, client devices, roaming, and application performance.
• Perform pre-deployment predictive designs and pre/post-validation surveys in Ekahau for offices, clinics, hospitals, and other complex environments.
• Interpret survey data and turn it into action: AP placement changes, power/channel tuning, antenna selection, cell sizing, capacity adjustments, and remediation plans.
• Validate coverage, capacity, roaming, voice/video readiness, and client experience after changes, upgrades, or new deployments.
• Support wireless upgrades, controller migrations, code updates, AP replacements, and incident response during maintenance windows and live outages.
• Work on-site when needed to troubleshoot, replace failed hardware, collect RF data, and verify user impact is actually resolved.
• Produce professional documentation: HLD/LLD notes, survey reports, MOPs, rollback plans, RCA documents, and concise leadership updates.
• Partner with LAN, security, server, telecom, and endpoint teams when wireless problems cross boundaries

Essential knowledge for this position

• Cisco enterprise wireless architecture, including modern controller-based deployments and day-to-day operational support.
• Wireless troubleshooting for real client problems: sticky clients, poor roaming, low RSSI/SNR, high retries, co-channel interference, adjacent-channel interference, DHCP/authentication failures, and application-specific complaints.
• Ekahau predictive design, active survey, passive survey, sidekick usage, report interpretation, and pre/post validation methodology.
  RF fundamentals and how they translate into real design decisions: attenuation, channel width, contention, basic rate impact, power balance, 2.4/5/6 GHz tradeoffs, voice design, and capacity planning.
• Supporting the wired side enough to isolate whether the issue is actually wireless, switching, PoE, uplink, NAC, or upstream services.
   

• Bachelor degree in Computer Science or a related discipline, or an equivalent combination of education and work experience. Masters degree preferred.
• Eight years of diverse work experience in IT with a minimum of six years experience in systems analysis and application program development, or an equivalent combination of education and work experience.

Specific Skills: 

• 5+ years of hands-on enterprise wireless engineering experience.
• Demonstrated experience configuring wireless controllers and enterprise APs from scratch rather than only inheriting existing environments.
• Strong hands-on troubleshooting background with production incidents involving controllers, APs, and client devices.
• Direct Ekahau experience for both design and validation surveys.
• Experience delivering survey findings in a professional report that includes findings, root cause, and recommended remediation.
• Solid understanding of switching, VLANs, PoE, DHCP, DNS, NAC/802.1X, and how they affect wireless outcomes.
• Able to explain technical findings clearly to engineers, managers, and non-technical stakeholders.
• Able to work on-site for surveys, deployments, troubleshooting, and hardware replacement as required.
   

Strongly Preferred: 

• Healthcare, campus, warehouse, manufacturing, or other high-density / high-complexity wireless environments.
• Experience with voice over Wi-Fi, location-based use cases, medical devices, or latency-sensitive applications.
• Experience with controller upgrades, large AP refreshes, and code migrations with minimal user impact.
• Relevant certifications such as CWNA/CWDP/CWAP, ECSE, or Cisco wireless certifications.
