How does a Security Engineer typically collaborate with other IT teams within an organization?

Security Engineers work closely with various IT teams such as network administrators, software developers, and system administrators to ensure security protocols are integrated at every level. This collaboration often involves conducting security assessments, reviewing code for vulnerabilities, and assisting with incident response. Regular meetings and cross-functional projects are common, as Security Engineers provide guidance on best practices and help teams understand potential threats. Effective communication and teamwork are key, as security is a shared responsibility across the organization.

What Is a Security Engineer?

A service provider is responsible for delivering professional quality services on behalf of a business or organization. The types of services vary depending on the businesses they work with. Many companies partner with experts in the local community to perform functions on their behalf rather than developing the expertise in-house. A service provider performs the services based on a written legal agreement and charges fees for their work.

What are Security Engineers?

Security Engineers are professionals responsible for designing, implementing, and maintaining systems and protocols to protect an organization’s computer networks and data. They analyze security measures, identify vulnerabilities, respond to incidents, and ensure compliance with security standards. Their work helps prevent unauthorized access, data breaches, and cyber attacks, making them essential to an organization's overall IT security. Security Engineers often collaborate with IT teams, management, and other stakeholders to build a robust security infrastructure.

What are the key skills and qualifications needed to thrive as a Security Engineer, and why are they important?

To thrive as a Security Engineer, you need expertise in information security principles, network architecture, vulnerability assessment, and commonly a degree in computer science or a related field. Familiarity with tools like SIEM systems, firewalls, intrusion detection/prevention systems, and certifications such as CISSP or CEH are typically required. Strong problem-solving skills, attention to detail, and effective communication set outstanding Security Engineers apart. These competencies are essential to proactively protect organizations from cyber threats, ensure compliance, and minimize security risks.

Job description

Position Summary: 

League is looking for a Principal Security Engineer to serve as the senior technical leader within our Security Engineering organization. This role entails designing and driving security architecture across a rapidly AI-native engineering environment, in close partnership with Product Security and Security Operations.

Product Security owns day-to-day security reviews and vulnerability management; Security Operations owns detection and response. This role sets technical direction and design for the organization's most complex and novel systems, including AI/agentic architectures, and serves as the connective tissue that makes the broader security function more effective.

The right person for this role doesn't wait for a ticket. They show up in design conversations, ask the right question at the right moment, and leave engineering and security colleagues alike more capable than they found them - all while being a strategic cross-functional partner that people enjoy collaborating with.

What you'll be doing: 

  • Design and implement security architecture and controls across encryption/key management, IAM, and core infrastructure
  • Set technical direction and design for the organization's most complex and novel systems - including AI/agentic architectures, major platform changes, and novel integrations
  • Partner proactively with engineering and product teams on secure-by-default design, embedding security capability directly into their workflows
  • Provide technical mentorship to Security Software Engineering and to individuals within Product Security and Security Operations, raising technical capability across the broader security function
  • Serve as senior technical escalation point and design advisor to Product Security and Security Operations on complex technical questions, without owning execution of their programs
  • Set direction and design for security automation initiatives, partnering with Security Software Engineering, who owns implementation and build
  • Translate technical risk into business terms for leadership, customers, and compliance stakeholders

What you'll bring to the team: 

  • 8+ years in security engineering, with demonstrated depth in at least two of: encryption/key management, IAM, cloud security architecture, application security
  • Direct, hands-on experience securing AI-integrated systems including LLM applications, coding agents, or MCP-style tool integrations; not just familiarity with the concepts
  • Experience operating in a regulated environment (HIPAA, HITRUST, SOC 2, PIPEDA, or equivalent), including translating compliance requirements into engineering practice
  • Experience collaborating within a broader security organization (partnering with product/application security and security operations functions) rather than as a sole practitioner owning every function end-to-end
  • Able to strategically influence across peer functions and ensure alignment to overall Security objectives
  • Track record of influencing engineering decisions and behaviour without formal authority over the teams involved
