Sr. Software Engineer, SCADA

About Enurgen

Enurgen is building DUET, a generational platform for utility-scale solar that turns raw fleet telemetry into recovered revenue. We close the gap between what conventional monitoring can see and what it can diagnose, and across a portfolio it adds up to a lot.

At our core is DUET (DUal-sided Energy Tracer), a 3D, physics-based energy yield model spun out of SUNLAB at the University of Ottawa and built on 10+ years of R&D. The DUET Platform runs per-timestep model-vs-field comparisons across the full 30-year asset lifetime, from design through construction to operations, automating detection, prioritization, and reporting at the component level. An AI agent on top enriches the analysis with context and patterns across portfolios.

The software engineering work

This is the work closest to the equipment: on-prem software that keeps running when the WAN doesn't, ingesting OPC UA and MQTT/Sparkplug B straight from site SCADA infrastructure. Plant operators lean on it hardest in the moments the cloud isn't reachable, so it has to be right and it has to be there.

This is a software engineering role. You'll be writing the software that talks to SCADA systems, not configuring them.

What you'll do

• Own the collector's protocol adapters (OPC UA and MQTT/Sparkplug B today) and add new connection kinds as we push further into on-site collection
• Harden the parts operators depend on: the alarm engine, local rollups, and idempotent ingest that survives a network partition
• Help shape how we collect data on-site as latency requirements push us closer to the equipment. This is a direction we're actively exploring, not a fixed roadmap
• Extend loss attribution and issue detection workflows with our R&D team, from the data collection side
• Work directly with customer OT and controls teams when the problem benefits from it

What we're looking for

Required

• 5+ years building production software, ideally systems, embedded, or industrial
• Strong systems thinker. AI changed the leverage, so you architect solutions before reaching for code
• Strong Go, or deep systems experience in a comparable language and the appetite to make Go your home
• Hands-on experience with industrial protocols: OPC UA, Modbus, DNP3, or MQTT/Sparkplug B
• Track record of building greenfield software in a startup-shaped environment: small team, fast iteration, real customers
• Strong written and verbal communication, including with non-engineering stakeholders

Strong pluses

Any one of these moves you up the list:

• SCADA or data collection experience in renewables. Wind counts fully; the concepts transfer
• OLAP / time-series database experience. We run ClickHouse at the edge and in the cloud
• OT security frameworks: NERC CIP, IEC 62443
• Ignition or a comparable SCADA platform
• Performance-sensitive or low-latency systems work

Not required

• A solar background specifically. Wind and other renewables transfer directly. You'll pick up plant physics; we don't expect you to walk in with it.
• Front-end experience. Useful, not required.

How we work

• Small, fast increments. Getting something real in front of operators usually beats polishing it longer in isolation.
• Tight feedback loops. We learn from short experiments with real customers, not speculative roadmaps.
• Focus over breadth. Fewer things, done well.
• Engineers paired with coding agents. AI is part of how we write code, debug, document, and analyze data. It's built into the workflow, not bolted on the side.
• High-touch and Slack-driven. Threads carry the work async, huddles when priorities move fast. No meetings to fill calendars.
• Small enough that nobody hides. Everyone ships to production, and everyone talks to customers.
• Engineering and R&D at the same table. The decisions are sharper for it.

Location

Remote or hybrid. Office in Ottawa, Ontario, Canada. Openness to occasional travel is a nice to have.
