Full job description

Inclusion without Exception:

Tata Consultancy Services (TCS) is an equal opportunity employer, and embraces diversity in race, nationality, ethnicity, gender, age, physical ability, neurodiversity, and sexual orientation, to create a workforce that reflects the societies we operate in. Our continued commitment to Culture and Diversity is reflected in our people stories across our workforce and implemented through equitable workplace policies and processes.

Tata Consultancy Services (BSE: 532540, NSE: TCS) is the technology partner of choice for industry-leading organizations worldwide. Since its inception in 1968, TCS has upheld the highest standards of innovation, engineering excellence and customer service.

It has set an aspiration to become the world's largest AI-led technology services company and is enabling its clients to transform themselves across the full AI stack, from infrastructure to intelligence.

Rooted in the heritage of the Tata Group, TCS is focused on creating long term value for its clients, its investors, its employees, and the community at large. With a highly skilled workforce spread across 56 countries and 194 service delivery centers across the world, the company has been recognized as a top employer in six continents. With the ability to rapidly apply and scale new technologies, the company has built long term partnerships with its clients. Many of these relationships have endured into decades and navigated every technology cycle, from mainframes in the 1970s to artificial intelligence today.

Job Summary:

Security Hardening: Implement and enforce AD security best practices (e.g., securing LDAP channels, disabling legacy protocols like NTLM, and managing privileged accounts).

Migration/Upgrades: Proven experience with AD migrations (e.g., functional level upgrades, domain consolidations) or Windows Server upgrades.

Monitor AD health: Oversee domain controllers, replication, and DNS integration to prevent outages.

Execute production changes: Apply patches, promote domain controllers, and adjust configurations following strict change control processes, primarily scheduled during nights and weekends to minimize business impact.

Troubleshoot platform issues: Resolve replication delays, authentication failures, or Group Policy conflicts using tools like Repadmin or DCdiag.

Support IAM and teams: Provide runbooks, guidance, and hands-on help when IAM or other support teams encounter AD-related issues.

Ensure compliance: Align AD operations with regulatory standards (e.g., internal policies) and audit requirements.

Automate routines: Use PowerShell or scripting to streamline tasks like log analysis or system checks.

Collaborate cross-functionally: Work with cybersecurity, networking, and other teams to support business needs.

Document processes: Maintain technical guides and share knowledge with the IPEM team.

On-call duties: Participate in rotations, including nights and weekends, for urgent incidents.

Required Experience: Active Directory operations (replication, domain controller management, Group Policy infrastructure).

Hands-on experience with AD troubleshooting and monitoring tools.

Scripting proficiency (PowerShell preferred) for automation.

Familiarity with PAM, Zero Trust principles, and CIS benchmarks.

Skills & Mindset:

Adaptable: Shift priorities smoothly in a dynamic setting.

Detail-oriented: Ensure accuracy in system configurations, compliance checks, and following processes and procedures.

Collaborative: Build relationships across teams and communicate clearly.

Proactive: Identify risks and propose solutions."

Salary Range - CA$ 90,000 - CA$ 120,000 Per Year
