Senior Sales Engineer (Canada)

Location: remote in Canada. Vancouver-based, or Toronto or elsewhere on Eastern Time, preferred.
About the roleD3 Security, headquartered in Vancouver, builds Morpheus AI: an AI SOC platform that investigates and responds to every alert across a customer's SIEM, EDR, identity and cloud tools. As a Senior Sales Engineer reporting to the Sales Director, you'll own the technical side of our deals and run the proofs of concept (POCs) that win them, often head to head against other AI SOC vendors.
What you'll do
Run discovery and turn the customer's needs into POC success criteria they sign off.
Set up POC environments: connect SIEM, EDR, identity and ticketing tools, map fields and get live alerts flowing.
Tune Morpheus AI triage rules, playbooks and response actions to the customer's data and SOC process.
Measure AI verdicts against analyst decisions, and report accuracy, false-positive reduction and speed.
Deliver demos and technical deep dives to SOC teams, engineers and CISOs.
Answer security, AI governance and data residency questions, in writing when needed.
Work closely with the VP of Product and the product team: share what customers need, bring back gaps with a clear root cause and customer impact, and help shape new features.
Share what you learn with the SE team.
