About The Position

We are seeking a visionary Principal Security Engineer - Temporary to architect the next generation of Identity at Achieve. In the evolving Fintech landscape, Identity is no longer just a perimeter—it is our primary security fabric. You will move us beyond static governance into a world of Continuous Adaptive Trust, where identity is dynamic, risk-aware, and invisible to the end-user. As a senior technical leader within the Information Security Engineering team, you will design and build scalable systems that secure our most critical assets: our people, our customers, and our sprawling ecosystem of non-human workloads. You aren't just managing tools; you are engineering a trust platform that enables a fast-moving, cloud-native financial enterprise. This is a temporary assignment that we expect will go on for approximately one year.

• 5+ years focused on identity and access management.
• Proven experience in designing and implementing enterprise-scale Identity solutions.
• Drive security automation and "Builder" Mentality by architecting and implementing automation-first solutions (e.g., scripts, APIs, Infrastructure as Code) to eliminate reliance on manual governance processes and ensure security policy is enforced at scale and embedded into developer workflows.
• Hands-on experience with leading IAM platforms and technologies, such as: Identity Federation: Azure AD/Entra, Okta, Ping Identity, ADFS IGA (Identity Governance and Administration): SailPoint, Saviynt, Oracle Identity Manager PAM (Privileged Access Management): CyberArk, Delinea, BeyondTrust Directory Services: Active Directory, Azure Active Directory, LDAP
• Deep knowledge of IAM principles, best practices, and security models.
• Proficiency in scripting languages (e.g., PowerShell, Python) for automation and integration.
• Understanding of network security, operating systems, and database concepts.
• Familiarity with API security and microservices architecture.
• Deep mastery of identity protocols and standards: IODC, OAuth 2.0, SAML, and SCIM, with a specific focus on mTLS and JWT security.
• Expert-level experience with cloud-native IAM (AWS IAM, Azure Entra ID, GCP Cloud IAM) and managing identity in distributed microservices architectures.
• Strong experience with Terraform and container orchestration (Kubernetes).
• Excellent analytical and problem-solving skills.
• Strong communication (written and verbal) and interpersonal skills.
• Ability to work independently and as part of a collaborative team.
• Strong project management and organizational skills.
• Proven ability to strategically influence and expertly negotiate with stakeholders across all organizational levels.

Nice To Haves

• Master's degree is a plus.
• Fintech/High-Growth Experience: Experience working in regulated environments where speed and compliance must coexist.

• CISM (Certified Information Security Manager)
• Relevant vendor certifications (e.g., Microsoft Certified: Identity and Access Administrator Associate/Expert, Okta Certified Professional/Administrator/Consultant).

Responsibilities

• Transition the enterprise from static, role-based access to a Risk-Based Authorization model that evaluates signals (device posture, behavior, location) in real-time.
• Enhance the enterprise Identity strategy, roadmap, and architecture in alignment with business goals and security policies.
• Design and architect comprehensive Identity solutions, including identity lifecycle management, non-human lifecycle management, authentication (MFA, SSO, passwordless), authorization, access governance, and Privileged Access Management (PAM).
• Evaluate and select appropriate Identity technologies and platforms.
• Create and maintain detailed architectural documentation for Identity solutions.
• Lead the strategy and architecture for comprehensive Identity and Access Management (IAM) solutions, explicitly managing User Identities, Workload & Machine Identities (including Service Mesh, Kubernetes, Lambda, and APIs), and other non-human identities across on-premises and cloud environments to govern access rights and privileges.
• Lead the implementation and integration of Identity solutions across various on-premises and cloud environments (e.g., Azure AD, AWS, GCP, Okta, Entra).
• Integrate Identity systems with enterprise applications, platforms, and services using standard protocols (SAML, OAuth, OpenID Connect, SCIM).
• Design and implement strategies to secure non-human machine identities, service accounts, APIs, and automation, utilizing Zero Standing Privilege principles and engineering "Just-in-Time" (JIT) access workflows to eliminate persistent administrative overhead, reduce the blast radius of potential compromises, and enforce strict, least-privilege, and Zero Trust security principles.
• Develop and configure identity provisioning and de-provisioning workflows.
• Partner with the SOC to build ITDR capabilities that detect and automatically neutralize identity-based attacks, such as session hijacking, token theft, and MFA fatigue.
• Act as a "Security Partner" for engineering teams to foster secure development practices.
• Drive successful adoption by collaborating with diverse stakeholders (business units, technology teams, application developers) and translating complex cryptographic and identity concepts into clear business value for product owners and executive leadership.
• Provide technical leadership and guidance, championing and delivering self-service Identity APIs and SDKs to enable developers to build secure products with minimal friction (Developer Experience - DevEx).
• Provide technical leadership, mentorship and guidance to Identity Engineers and other team members.
