Senior Execution Engineer leading capital maintenance and operational projects across Enbridge’s Prairie Region pipeline network. Providing engineering leadership, contractor coordination, and safe project delivery.
About the role
- Senior Corporate Engineer II responsible for the architecture of security-critical platforms at Instacart. Collaborating with engineering teams to enhance identity and access management infrastructure.
Responsibilities
- Own the architecture, security, and day-to-day operations of our enterprise Okta tenant, including delivery of Okta Identity Governance (OIG), lifecycle management, SCIM provisioning, SSO integrations (SAML/OIDC), MFA, risk-based policies, and device trust.
- Design and maintain Infrastructure-as-Code for identity and access using Terraform, building reusable modules, guardrails, and automated workflows integrated with HRIS and ITSM systems to achieve least-privilege and timely provisioning/deprovisioning.
- Architect, operate, and continuously improve Instacart’s office network infrastructure (firewalls, routing/switching, wireless) across SF, NYC, and Toronto; drive zero-trust segmentation, observability, capacity planning, and vendor/partner management.
- Lead and participate in incident response for identity and network events, drive rapid mitigation and root-cause analysis, and implement durable remediations through post-incident reviews and change management.
- Standardize and execute certificate and key lifecycles for SAML/TLS across SaaS applications; eliminate manual toil with scripting and robust runbooks that increase reliability and auditability.
- Partner with Security and Compliance to meet controls and audit needs (e.g., access reviews, evidence collection), improve access risk management, and unlock license savings via automated revocation and right-sizing.
- Mentor teammates, elevate documentation and operational excellence, and help shape the roadmap by prioritizing high-impact work in a rapidly evolving environment.
Requirements
- 7+ years of experience in corporate IT engineering or a related field with a focus on identity and access management (IAM) and enterprise networking.
- 3+ years of hands-on administration of Okta in production (1,000+ users), including SSO integrations (SAML/OIDC), SCIM provisioning, MFA, and policy design.
- 2+ years implementing identity governance and automation using Okta Workflows, Okta Identity Governance (OIG), or an equivalent IGA platform.
- Proficiency with Infrastructure-as-Code and automation: Terraform (required) and at least one scripting language (Python, Bash, or PowerShell).
- Demonstrated experience planning and executing certificate rotations and key management for SAML/TLS across multiple SaaS applications.
- Hands-on experience operating and troubleshooting office network infrastructure (switching, routing, wireless, firewalls) and VPN/zero-trust access using technologies such as Cisco/Meraki, Aruba, and Palo Alto.
- Proven track record leading critical incidents and executing structured change management, including authoring runbooks and conducting post-incident reviews.
- Working knowledge of endpoint management and device trust (e.g., Jamf, Kandji, Intune) and integrating device posture into access controls.
- Bachelor’s degree in Computer Science, Engineering, Information Systems, or equivalent practical experience.
Benefits
- Competitive salary
- New hire equity grant
- Annual refresh grants
- Flex First remote work policy
