Project Engineer

Location: Los Angeles, CA or Chicago, IL

Reports to: Vice President of Engineering

Zentro is one of the largest independent internet service providers focused exclusively on multi‑dwelling units (MDUs) in the United States. Following our recent merger with BAI Connect, Zentro now serves over 100,000 subscribers across key markets including Chicago, Los Angeles, and Detroit. We specialize in delivering bulk internet and managed Wi‑Fi solutions purpose‑built for apartment communities, high‑rises, and mixed‑use developments. Our fully owned network infrastructure, resident‑first support model, and tailored technology stack enable us to offer a refreshingly different alternative to legacy providers—one rooted in simplicity, reliability, and satisfaction.

The Project Engineer is responsible for designing, standardizing, and delivering network projects that are deployable, supportable, and scalable. This role serves as the critical bridge between initial sales requirements and long‑term operational stability, ensuring that every deployment is transitioned cleanly to the Network Operations Center (NOC). You enable execution by creating the blueprint for success—ensuring our network is built once, supported forever, and scaled without heroics.

• Design & Engineering: Own the high‑level and detailed designs for site topology (POP, access, backhaul), IP addressing, and VLAN schemes.
• Set the Standard: Create and maintain the "Gold Standard" for physical and logical builds—from which routers we use to how cables are labeled in the rack.
• Enable the Field: Support our installers by providing clear configuration files, Bill of Materials (BOM), and design clarifications.
• The "Clean Handoff": Ensure every project is 100% ready for the NOC. This means monitoring is active, documentation is stored, and management access is verified before you sign off.
• Risk Mitigation: Proactively identify Line of Sight (LOS), power, or capacity risks before the first piece of hardware is ordered.

• Ownership: High‑level and detailed network designs (MDF/IDF/POP, access, backhaul).
• Tasks: Translate expansion requirements into deployable designs; validate Line of Sight (LOS), throughput, and redundancy; manage IP addressing and VLAN design.
• Deliverables: Network diagrams, IP plans, and design approval sign‑offs.

• Ownership: Physical and logical build standards and Bill of Materials (BOM) accuracy.
• Tasks: Define approved hardware/software (routers, radios, power, racks); enforce standards during project life cycles; manage exceptions to prevent "snowflake" configurations.
• Deliverables: Standards documentation, approved hardware lists, and validated BOMs for procurement.

• Ownership: Engineering readiness and "as‑built" validation.
• Tasks: Ensure equipment is configured and staged; provide design clarification to field installers; resolve technical roadblocks during deployment.
• Deliverables: Configuration files, updated "as‑built" diagrams, and build validation sign‑offs.

• Ownership: The engineering side of operational readiness.
• Tasks: Ensure monitoring and management access are enabled before project close; conduct formal handoff walkthroughs with the NOC team.
• Deliverables: Completed handoff checklists and task NOC acceptance sign‑off.

• Ownership: Engineering risk visibility and scalability.
• Tasks: Identify capacity, power, and LOS risks early; review post‑mortems to improve standards; recommend automation to reduce operational burden.
• Deliverables: Risk logs, design adjustments, and version‑controlled standards updates.

• Sales Engineering: To clarify requirements.
• Field Ops: To support deployment and validate physical builds.

• Fixed Wireless: Strong understanding of RF fundamentals, Link Budgets, and wireless backhaul technologies.
• Network Depth: Proficiency in Layer 2/3 networking, specifically OSPF, Ethernet, and VLAN management.
• Tools of the Trade: Experience with GIS‑based planning tools…
