Lead IAM Developer (One Identity Manager) – Investment Banking

Rate: £650 per day (Inside IR35)

Location: London (City) – Fully Remote

Duration: Initial 6-month contract with long-term pipeline / high potential to extend

The Opportunity

We are seeking a high-calibre Lead Analyst/Developer to spearhead the evolution and support of a global Identity & Access Management (IAM) platform within a tier-one investment banking environment. You will lead the technical delivery for the One Identity Manager (Quest) platform, acting as the primary subject matter expert for complex change projects and expert-level (L3) production support.

This is a "cradle-to-grave" delivery role where you will bridge the gap between business requirements and technical execution, ensuring the bank’s identity lifecycle remains secure, compliant, and highly automated.

The Role:

Technical Leadership: Lead the analysis, design, and development of workflows, provisioning processes, and connectors specifically within the One Identity Manager

ecosystem.

End-to-End Delivery: Own the pipeline of small-to-large change items—from requirements capture and technical documentation to packaging, deployment, and release planning.

Systems Integration: Architect and configure seamless integrations between One Identity and core infrastructure including Active Directory, Azure AD, and SAP.

Governance & Compliance: Implement and refine Role-Based Access Control (RBAC), automated provisioning/de-provisioning, and strict compliance rules to meet rigorous regulatory standards.

Mentorship: Act as a technical escalation point for L2 support teams, providing knowledge transfer and high-level diagnostic skills for complex production issues.

Your Profile:

IAM Specialist: A proven track record of implementing and managing One Identity Manager (Quest) in complex, large-scale environments (Investment Banking experience is highly desirable).

Technical Toolkit: Proficiency in SQL, VB.Net, and PowerShell

is essential for custom development and automation.

OIM Expertise: Deep hands-on experience with OIM Designer, Object Browser, Transport, and Data Importer.

Infrastructure Knowledge: Strong understanding of Active Directory architecture, MS-SQL Server, and LDAP.

Communication: Ability to manage the expectations of senior stakeholders and translate business needs into robust technical designs.

Why Apply? This role offers the chance to operate at a lead level within one of the world’s most respected financial institutions. You will handle a high-impact workstream where your design decisions directly influence the security posture of the bank's global operations.
