Job Description

Curinos is looking for an experienced Senior Security Engineer to join our Information & Security team. Operating in an AWS-native environment with select on-premises workloads, this role drives and advances key security capabilities across cloud security posture management, vulnerability management, threat detection and detection engineering, application security, and incident response. The ideal candidate brings deep hands-on experience with modern cloud and security tooling, independent designs and implements solutions for new initiatives, and partners with engineering and operations teams to reduce risk across our hybrid environment. Working closely with Information Security, IT, and Engineering teams, this role sets priorities within its areas of responsibility, drives remediation to closure, mentors more junior team members, and serves as a subject-matter expert on security issues.

Responsibilities

Run day-to-day security operations and engineering activities across our cloud and hybrid environment, prioritizing work across competing risks based on severity, timelines, and dependencies, and partnering with Information Security, IT, and Engineering teams to identify, drive, and verify remediation while continuously improving detection and response capabilities
Monitor and respond to findings in AWS Security Hub and Amazon GuardDuty; tune and author detections to improve signal quality and reduce false positives, and define remediation standards that engineering teams can follow
Independently manage cloud security posture using our CNAPP platform, setting risk prioritization criteria, driving remediation with asset owners, and grouping recurring findings to identify root causes and recommend preventative measures
Drive the vulnerability management lifecycle using an enterprise platform, performing assessments, applying risk-based prioritization and SLAs, and driving findings to resolution across a mixed asset inventory; coordinate penetration tests and remediation of their results
Design and embed application security controls within development pipelines, partner with product and platform engineers to design remediation solutions, clearly communicate implications and timing of decisions, and recommend enhancements to code resiliency
Operate and improve endpoint and network detection and response tooling, develop and tune detections, lead telemetry and threat investigations end to end, and coordinate response
Lead investigation and response for security incidents, including high-severity events; lead root-cause analysis and drive post-incident corrective actions to completion across the relevant teams.
Define and report security posture metrics and KPIs; explain complex findings and their implications to technical peers, leaders, and stakeholders outside the team, and respond to targeted technical questions from external audiences such as auditors, clients, and vendors.
Independently automate security operations using scripting and infrastructure-as-code, developing reusable tooling that improves team efficiency and consistency.
Stay current with emerging threats, CVEs, and platform changes; evaluate new security tooling and methodologies through proofs-of-concept and recommend adoption where they reduce risk.
Work cross-functionally with engineering, information technology, and infrastructure teams to consult on security matters and champion secure-by-design practices.
Mentor and provide technical guidance on security matters to junior team members and advise engineering teams on secure design.

Key Skills

AWS cloud security: Deep hands-on expertise designing and operating AWS native security services such as Security Hub, GuardDuty, CloudTrail, IAM, and VPC, including detection tuning and guardrail design.
AWS cloud infrastructure: Strong working knowledge of AWS infrastructure and services, sufficient to assess architecture for security risk and design remediations.
CNAPP / cloud posture management: Hands-on proficiency in cloud posture management, identifying misconfigurations, prioritizing risk, driving remediation, and recommending preventative controls within a CNAPP platform.
Vulnerability management: Proficiency driving the vulnerability management lifecycle, including scanning, risk-based prioritization, SLA definition, and driving remediation to closure across a mixed aset inventory.
Endpoint and network threat detection: Hands-on experience operating and tuning endpoint and network detection tooling, including authoring detections, leading investigations, and coordinating response.
Application security tooling: Experience designing and integrating application security controls (software composition analysis, SAST, secure pipelines) into engineering workflows and partnering with developers on remediation.
Linux and Kubernetes: Solid hands-on experience securing Linux and Kubernetes environments, including hardening, monitoring, and leading remediation.
Security frameworks: Practical experience applying and helping mature NIST 800-53, CIS Benchmarks, and/or ISO 27001 controls, including supporting audits and assessment responses.
Security automation & IaC: Proficiency building automation and security-as-code (e.g., Terraform, Python) to operationalize and scale security controls.
Technical leadership: Ability to mentor junior team members and act as a domain subject-matter expert.

Salary Range: 100,000-110,000 CAD (plus Bonus)
