About the role

Software Engineer focused on detection systems at Doppel, a backend/ops role building AI-native social engineering defense platforms at scale. Owns end-to-end delivery from requirements to released production services, with emphasis on high-throughput ingestion, enrichment, scoring, alerting pipelines, APIs, dashboards, threat-linking infrastructure, and automation.

Responsibilities

  • Hands-on experience building production backend services or full-stack features (or equivalent). Proven record of shipping end-to-end: design → implementation → testing → monitoring → oncall.
  • Strong mastery of at least one backend language (Python, Go, Java, or Node) and comfort with web APIs, async processing, and service frameworks.
  • Solid system design skills: experience architecting scalable, fault-tolerant systems (sharding, caching, queueing, idempotency, backpressure).
  • Experience building and operating large data pipelines (batch or streaming), working with warehouses or OLAP systems for analytics, and designing efficient schemas for scale.
  • Deep practical experience with backend concerns: databases (SQL + NoSQL), caching, message queues, rate limiting, retries, and cost/latency tradeoffs.
  • Strong observability, debugging and incident response skills: structured logging, tracing, dashboards, SLOs/alerts, and the ability to triage and fix production issues.
  • Product ownership and excellent cross-functional communication — you’ll collaborate with Operations, Customer Success, Sales, to deliver measurable outcomes.
  • As part of our Toronto team, you’ll:
  • - Work on a wide range of asks that protect billions of people from digital impersonation
  • - Have complete end to end ownership - from directly collecting customer requirements to continuously iterating on shipped releases.
  • - Mentor junior engineers, make key product decisions, and foster a high-performing team culture
