Alberta is becoming one of Canada’s fastest-growing data center markets, and ROHL Global Networks is building the fiber that connects it. We own and operate a long-haul fiber optic network across the province, and we’re expanding it to serve the large data center operators and carriers moving in. Our customers come to us for dark fiber (IRU), lit wavelengths and Layer 2 Ethernet transport.

We’re a pure transport network: no internet service, no IP transit, no peering, so this role is about optical and transport design, start to finish. We’re looking for a Senior Optical Network Engineer to own the design of everything that lights our fiber: This is a chance to shape a network while it grows, not just maintain one. You’ll take customer demand and route plans and turn them into designs that get built and stay up, including link budgets, channel plans, rack elevations, power and BOMs, handed off so cleanly that deployment and operations can run with them.

And as the network scales, you’ll be the go-to expert supporting our Network Operations team. As our Senior Optical Network Engineer, you’ll be the design authority for how our fiber comes to life. You’ll own the architecture of our optical and Layer 2 transport layers, from the first link budget to the final handoff, and make sure every route and customer circuit is built to perform, built to last, and easy for our operations team to support.

You’ll work closely with deployment, operations, outside plant, sales and our vendors, and you’ll have real influence over the standards and reference designs that shape the network as it grows. Design our optical transport network Design DWDM systems for regional and long-haul routes, including ROADM/FOADM node architecture, amplifier placement (EDFA, and Raman where justified), and fixed and flexible-grid channel plans. Engineer point-to-point and multi-site DCI using coherent pluggables (100G–400G+) and compact DCI platforms, including IP-over-DWDM where it lowers cost per bit.





Build link budgets and OSNR/reach analysis covering span loss, chromatic dispersion, PMD, nonlinear penalties, and aging and repair margins, using vendor planning tools and fiber characterization data (OTDR, CD/PMD). Design the Carrier Ethernet service layer (MEF E-Line / E-LAN) that delivers Layer 2 circuits to data center customers. Shape the customer experience Define service SLAs (latency, availability, jitter) and the monitoring that proves we’re meeting them.

Turn designs into buildable sites Produce rack elevations, power budgets (-48 VDC and AC), heat loads, fiber patching/ODF layouts and cross-connect schedules for PoPs, huts and colocation sites, including our Acheson facility. Deliver site-ready design packages, BOMs and method of procedure (MOP) documents for deployment teams and contractors. Translate customer demand and traffic forecasts into capacity plans and staged upgrade paths.

Evaluate vendor platforms and optics, run lab and field trials, and provide technical input to RFx and commercial negotiations. Define network standards, reference designs and naming/inventory conventions, and keep design records current in the inventory system. Support acceptance testing and turn-up, serve as Tier 3 escalation for design-related faults, and back up the operations team during incidents and planned maintenance.

A bachelor’s degree in Electrical, Telecommunications or Computer Engineering, or equivalent hands‑on experience. 694.1 grid, OSNR, chromatic dispersion, PMD, amplifier gain/tilt and span engineering. Comfort reading and applying fiber characterization data (OTDR traces,



loss and CD/PMD reports) and working with OSP teams on route and diversity constraints. A track record of producing complete design packages, including drawings, rack elevations, power and heat calculations, BOMs and MOPs.

Robust written communication and the confidence to explain and defend a design to operations, finance, customers and vendors. A valid driver’s license and willingness to travel regularly (approximately 20% of the time) to PoPs, huts and data centers along the network, balanced with office‑based design work. Availability for occasional after‑hours support during maintenance windows, cutovers and incidents.

The ability to work in equipment rooms and meet site access and safety requirements, including laser safety, ESD and landlord inductions.

Experience with open and disaggregated optical networking, including open line systems, alien wavelengths, OpenROADM or TIP. Familiarity with colocation and carrier‑neutral data center environments, including meet‑me rooms, cross‑connect ordering and landlord standards.

Experience with network automation and telemetry, such as NETCONF/YANG, gNMI, or Python or Ansible for design and config generation. Exposure to planning tools, including vendor planning software, GIS/route tools, or inventory/OSS systems. L3 VPN, BGP or SRv6 design experience (helpful for working with customers' IP teams) Competitive wages, commensurate with experience An annual performance bonus based on individual objectives and overall company performance A comprehensive benefits plan including dental, vision and extended health for you and your family Company vehicle or vehicle allowance for site travel On‑call stipend for scheduled maintenance windows Paid vendor certifications, plus ongoing training and professional development opportunities On‑Site in Acheson / Edmonton, AB – with travel to PoPs, huts and data center sites along the network (approx.
