Job Description

We are building a next-generation, AI-first financial services platform on Microsoft’s ecosystem—where identity, endpoint, messaging, and AI interaction layers are unified under a Zero Trust security model

3. Secure Messaging & Collaboration (Exchange Online)


  • Configure mail flow rules and transport policies

  • Support anti-phishing protections (SPF, DKIM, DMARC)

  • Assist with Data Loss Prevention (DLP)

  • Ensure secure and auditable communications

4. Microsoft 365 Security, Compliance & Copilot Governance


  • Support Microsoft Defender and Secure Score initiatives

  • Assist with Microsoft Purview (retention, classification)

  • Help govern Microsoft Copilot usage within compliance boundaries

  • Contribute to AI-safe data access and governance

5. API & Automation Layer (Microsoft Graph)


  • Assist with secure Graph API interactions

  • Support identity-aware automation workflows

  • Ensure API authentication, authorization, and auditability

6. Data Protection


  • Support encryption standards (TLS 1.2+, encryption at rest)

  • Maintain secure authentication and identity token practices

  • Ensure zero exposure of sensitive data

7. User Experience (Security-First Design)


  • Help design friction-aware security workflows

  • Support intuitive onboarding and secure collaboration

  • Balance usability with strict policy enforcement

What We’re Looking For

Core Technical Foundations


  • Basic understanding of:

  • Awareness of:
