Senior System Performance Engineer Full Time

Pre Deployment Activities: Conduct site surveys and CW testing to capture accurate RF, structural, and environmental details. Validate and refine iBwave designs based on real world constraints and customer discussions. Support design review, ensuring compliance with RF standards, coverage objectives, and product capabilities. Documentation & Engineering Coordination: Produce and maintain critical project documentation, including: Fiber Logical Diagrams, Rack Diagrams / Rack Elevations, Sector & PCI Mapping, CellHub Cascading Diagrams, As Built Designs. Ensure clear handoff of materials from survey through commissioning and closeout. Drive consistency and efficiency by developing engineering templates, standards, and workflows. Deployment & Commissioning Support: Provide construction and integration support to ensure systems are built and turned up according to design. Perform configuration reviews, parameter audits, and commissioning validation. Support FE/DET with on site or remote troubleshooting during installation and integration. Post Deployment Services: Conduct RF walk testing, throughput testing, and coverage validation after installation. Evaluate network KPIs to ensure performance meets expectations for reliability, coverage, and capacity. Perform troubleshooting and optimization to resolve performance gaps or design to field mismatches. Product, Process, and Cross Functional Feedback: Provide data driven performance feedback to PLM/PO for feature refinement, roadmap decisions, and design improvements. Collaborate with R&D and NPI on system behaviors identified during deployments or RF validation. Share best practices and participate in training/knowledge transfer sessions with FE, DET, and other engineering teams.
