IAM Lead

My client is building out a new IAM capability and is looking for a hands-on technologist to take ownership of it. This isn’t a people management role, it’s an individual contributor position for someone who combines deep technical expertise with strong judgement and the ability to influence across teams.

What does this mean?

You’ll act as the firm’s Identity and Access Management SME, responsible for designing and delivering secure authentication and authorisation solutions across a complex, high-performance global trading environment. You’ll set direction, make key design decisions, and work directly with engineering and security teams to bring them to life.

To be considered, you’ll need to show that you’ve led the design and deployment of IAM platforms within a Microsoft ecosystem (Active Directory, Entra ID, ADFS, ADCS) in a fast-moving, large-scale environment such as big tech or financial services.

What you’ll do:

• Lead the design, deployment, and evolution of IAM platforms across the Microsoft ecosystem (Active Directory, Entra ID, ADFS, ADCS).

• Drive the adoption of modern authentication standards, including passwordless solutions (FIDO2, YubiKeys, Windows Hello, Passkeys).

• Partner with infrastructure and application teams to integrate IAM services seamlessly into business-critical platforms.

• Contribute to strategic projects such as secure remote access from employee-owned devices and certificate lifecycle management.

• Act as an IAM subject matter expert, advising on best practices and influencing security architecture decisions across the firm.

What they’re looking for:

• 7–10 years of IAM engineering experience, ideally in financial services or complex enterprise technology environments.

• Deep knowledge of authentication protocols (Kerberos, PKI, OIDC, FIDO2) and Microsoft identity technologies.

• Strong design and integration skills, with the ability to balance technical depth with strategic vision.

• Excellent communication skills and the ability to influence stakeholders and collaborate across engineering, security, and business teams.

This is a rare opportunity to build and own IAM within one of the most sophisticated technology environments in finance. You’ll have visibility, autonomy, and the chance to shape how identity and access management evolves across the organisation.
