Senior Software Developer, Security Automation(Global Security)

RBC • Toronto, ON

About The Position

We are looking for a Senior Software Developer to join our Security Automation team, responsible for engineering and scaling our SOAR platform. This is a development-first role — you will design, build, test, and deploy automation software that powers security operations across the enterprise. The ideal candidate writes production-quality Python, thinks in APIs and data contracts, and treats infrastructure-as-code as a default.

Requirements

• 5+ years of professional software development experience in Python
• Strong understanding of REST API design and consumption (authentication patterns, HTTP methods, status codes, payload serialization)
• Experience with Git workflows, code review practices, and CI/CD tooling (Jenkins, GitHub Actions, GitLab CI, or equivalent)
• Familiarity with testing frameworks (pytest, unittest) and writing unit/integration tests as part of the development lifecycle
• Working knowledge of Docker, Linux, and command-line tooling
• Experience with data formats and protocols: JSON, YAML, XML, webhooks, message queues

Nice To Haves

• Prior experience with Cortex XSOAR (Demisto), Splunk SOAR, or similar orchestration platforms
• Familiarity with security concepts: incident response workflows, MITRE ATT&CK, threat intelligence, vulnerability management
• Experience with demisto-sdk or XSOAR content development framework
• Experience with big data technologies — data lakes, distributed processing frameworks (Spark, Hadoop), or large-scale data pipelines (Kafka, Airflow) for ingesting and correlating high-volume security telemetry
• Exposure to AI/ML concepts — working with LLMs, building AI-assisted workflows, prompt engineering, or integrating AI models into automation pipelines for tasks such as alert triage, anomaly detection, or natural language-driven investigation
• Exposure to databases (SQL/NoSQL) and data pipeline tools
• Background in building integrations with enterprise tools (ServiceNow, Jira, SIEM platforms, identity providers)

Responsibilities

• Design and develop automation playbooks, scripts, and orchestration workflows in Python following software engineering best practices (modularity, error handling, logging, testability)
• Write clean, maintainable, and well-tested code that adheres to team coding standards and passes peer review
• Build reusable automation libraries and frameworks that reduce duplication and accelerate future development
• Develop custom integrations in Python connecting XSOAR to internal platforms, REST/GraphQL APIs, databases, and third-party security tools
• Implement robust API client patterns — authentication, retry logic, pagination, rate-limiting, and schema validation
• Own the data contracts between systems; design normalized data models for cross-platform incident and telemetry flows
• Build and maintain CI/CD pipelines for XSOAR content delivery (linting, unit testing, integration testing, automated deployment)
• Manage version control workflows in Git — branching strategies, pull request reviews, and release management for automation content
• Containerize integrations using Docker; manage development and staging environments for pre-production validation
• Administer the XSOAR platform — upgrades, performance tuning, high-availability configuration, and monitoring
• Implement observability: structured logging, health checks, alerting on playbook failures, and execution metrics
• Design scalable patterns for incident classification, enrichment pipelines, and response orchestration
• Participate in Agile ceremonies (sprint planning, standups, retrospectives); estimate and deliver work within committed timelines
• Partner with SOC analysts and detection engineers to gather requirements and validate automation outcomes
• Produce technical documentation for integrations, runbooks for operational handoff, and knowledge transfer for the broader team

Benefits

• bonuses
• flexible benefits
• competitive compensation
• commissions
• stock where applicable
• Leaders who support your development through coaching and managing opportunities
• Support from a dynamic, collaborative, progressive, and high performing team, as well as world-class tools and training
• Ability to make a difference and lasting impact
• Work in a dynamic, collaborative, progressive, and high-performing team
• A world-class training program in financial services
• Opportunities to do challenging work
