Job Description:

Role Summary:

The Security Automation & Orchestration team builds automation that connects and enhances security capabilities across Security Operations. Working across technologies such as SIEM, endpoint security, cloud security, perimeter security, email security, cryptographic security, and other security platforms, the team develops solutions using Splunk SOAR, Python, APIs, and related technologies. Our automation helps monitor the health and configuration of security platforms, process and action security intelligence, identify gaps in security coverage, generate alerts and tickets, collect operational metrics, and remove repetitive manual work. Rather than owning a single security product, the team works across the Security Operations technology ecosystem, partnering with platform and operations teams to improve efficiency, reliability, consistency, and scale.

What will you do?

In Splunk SOAR, the successful candidate will design, develop, test and maintain complex automation solutions and playbooks using Python, integrating security platforms, APIs and enterprise systems to automate security and operational processes.
Within the Ansible Automation Platform, design and develop reusable automation workflows and components using YAML to support activities such as account provisioning, certificate management and the deployment and configuration of new systems.
Act as a senior technical escalation point for the automation platforms, troubleshooting complex application, integration, API, authentication and workflow issues and providing technical guidance during incident resolution.
Provide technical leadership and mentorship to junior and intermediate engineers, including code reviews, troubleshooting assistance, solution design guidance and the promotion of development and automation best practices.
Meet with stakeholders to translate business and security requirements into technical designs and automation solutions, identifying opportunities to simplify processes, reduce manual effort and improve reliability.
Lead the technical design and implementation of automation solutions supporting security initiatives and enterprise-level projects, including proof-of-concept/proof-of-technology activities, evaluation of new capabilities, integration with existing technologies and transition into production.
Establish and promote development standards and engineering practices for security automation, including source control, code quality, testing, error handling, logging, documentation, reusable components and maintainability.
Identify and lead continuous improvement opportunities across security platforms and operational processes, including addressing technical debt, improving automation reliability and reducing repetitive manual work.
Own solutions throughout their lifecycle, including design, development, testing, implementation, production support, maintenance and eventual retirement or replacement.
Lead the transition and operationalization of project deliverables into BAU, including defining support models, operational procedures, monitoring, RACI documentation, knowledge transfer and technical readiness for teams assuming ongoing support responsibilities.
Develop and maintain cyber security playbooks, technical documentation, procedures and knowledge-base articles supporting Incident Management, CSIRT and security operations.
Provide technical consultation and influence solution direction across projects involving security automation and supported security platforms, identifying architectural, operational and integration risks early in the development lifecycle.
Participate in the team's 24x7 on-call support rotation and serve as an escalation resource during major incidents, providing advanced troubleshooting, technical consultation, root-cause analysis and recommendations to prevent recurrence.
Collaborate with infrastructure, application, security and architecture teams to develop scalable and supportable integrations between security platforms and enterprise systems.
Drive automation maturity within the team by identifying opportunities for reusable frameworks, common libraries and standardized integration patterns rather than developing one-off solutions.

What you need to succeed?

5+ years of Python development experience, with demonstrated experience designing, developing, testing and supporting production-level automation and integrations.
An Information Technology university degree/college diploma in a related discipline, or equivalent combination of education and 7+ years of relevant Information Technology experience.
5+ years of experience within Cyber Security, Security Engineering, Platform Engineering, DevOps or a related technical discipline.
Strong experience developing and integrating solutions using REST APIs, JSON, authentication mechanisms and enterprise systems, with the ability to independently troubleshoot complex integration issues.

Strong understanding of software development practices, including source control (Git), code reviews, testing, error handling, logging, debugging and maintainable software design.
Demonstrated ability to act as a technical escalation point, independently diagnosing complex problems and providing technical direction during production incidents and major incident situations.

Professional designation in IT or Cyber Security, such as CISSP, CISM, CISA, GIAC, AWS or CompTIA Security+, is preferred.

Preferred skills:

Experience with SOAR tools (Splunk SOAR, Cortex XSOAR, etc)
Development experience 5+ years (Python, YAML, etc)
Experience with Ansible development.
Experience planning, researching, and developing security policies, standards, and procedures.
Knowledge of one or more: end-point detection and response, intrusion detection, crypto technologies, certificate management, email security, web content filtering technologies, cloud security.
Knowledge of Security Information and Event Management platforms including log types.
Experience with Windows and Linux based operating systems.
Experience in deploying enterprise level technology via managed projects.
Knowledge of networking technologies, firewalls, web application firewalls and intrusion prevention systems.
Knowledge of cloud technologies.
Knowledge of disaster recovery, technologies, and methods.
Strong communicator spoken and written with the ability to communicate technical issues to peers and management.

Must be able to satisfactorily complete applicable background checks prior to the start date and during employment, in accordance with Sun Life’s policies and practices.

What’s in it for you:

We’re honoured to be recognized as a 2026 Best Workplaces in Canada by Great Place to Work® Canada.
We are thrilled to be recognized by Excellence Canada with their top-level certification, the Canada Order of Excellence for Mental Health at Work®, for prioritizing employee well-being, fostering a positive work culture, and achieving excellence in mental health.
