About the role

Join Equitable Bank as a Senior Backend Engineer, designing innovative backend solutions for Fraud Engineering. Ensuring reliability and security in the banking experience for Canadian customers.

Responsibilities

Design and implement backend services and agentic workflows that:
Implement agentic task flows (tool use, orchestration, and workflow state) for back-office automation where the final decision remains human-owned
Build evaluation harnesses (runners, suites, regression gates) to validate correctness boundaries for non-deterministic systems
Strengthen cross-system lifecycle guarantees (handoff, session, termination, retries) using backend events/APIs rather than fragile UI triggers
Build/maintain knowledge ingestion pipelines that transform content into searchable indexes and support freshness + traceability
Implement production-grade observability (signals, traces, failure classification) so AI outcomes and integrations are explainable in incidents
Contribute to release readiness via trunk-based discipline, tagging, and evidence-driven release workflows
Own services end to end:
Service design, API contracts, and workflow state model
Test strategy (unit/integration/e2e) and evaluation suites for AI flows
Deployment and production support, including after-hours readiness in partnership with central teams

Strong backend engineering fundamentals (service design, distributed systems, async workflows).
Experience designing systems where correctness is enforced through contracts, tests, and runtime guarantees rather than tribal knowledge.
Practical experience with at least one of: agent orchestration, workflow engines, tool-calling systems, or evaluation frameworks for LLM/agent behavior.
Ability to reason about failure modes across system boundaries (vendor + internal) and build deterministic lifecycle handling.
Production mindset: observability, incident response, and operational readiness. **Comfort operating under data privacy constraints and consent-based integrations.
