Security & Vulnerability Assessment

  • Conduct thorough vulnerability assessments for mobile and web applications prior to VAPT submissions.
    • Identify and mitigate potential security risks at various stages of the application lifecycle.
    • Collaborate with cybersecurity teams to embed security best practices into development and deployment processes.

  • Design and implement robust API authorisation frameworks, ensuring secure access control and data protection.
    • Leverage standards like OAuth 2.0, JWT, and mutual TLS authentication for secure API communications.
    • Integrate OKTA for centralised identity and access management, ensuring secure authentication across applications

Cloud-Native Solutions:

  • Architect and manage cloud-native applications using AWS services, including ECS,Lambda, RDS, and more.
  • Implement infrastructure automation, monitoring, and logging solutions to ensure smooth cloud operations.
  • Ensure cloud environments are secure, scalable, and adhere to compliance requirements

Collaboration & Technical Leadership:

  • Lead architecture discussions, balancing security, scalability, and integration needs.
  • Work closely with DevOps, software engineering, and security teams to integrate security into the development lifecycle, especially within CI/CD pipelines.
  • Conduct technical reviews, offer guidance on API security, cloud architecture and enterprise integrations

Stakeholder Engagement:

  • Collaborate with business and technology stakeholders to align cybersecurity,scalability, and integration goals with business objectives.
  • Present technical solutions, risk assessments, and integration plans to senior management.
  • Interface with vendors, partners, and security auditors to ensure external integrations meet compliance and security standards.


Requirements:

  • Degree in Computer Science or equivalent.
  • At least 8-10 years of experience in software architecture, application assessment, and cloud-native solutions.
  • Experience conducting vulnerability assessments and preparing systems for VAPT.
  • Hands-on experience in defining API authorisation frameworks with standards like OAuth 2.0 and JWT.
  • Proven experience working with identity management platforms, especially OKTA, for centralised authentication and secure access control.
  • Strong background in Salesforce integration, with the ability to design secure and scalable solutions for enterprise application integration.
  • Extensive knowledge of microservices architecture, containerisation technologies (e.g., Docker), and orchestration tools like AWS ECS or Kubernetes.
  • Experience in building and deploying cloud-native architectures using AWS services, including ECS, Lambda, RDS, and more.
  • Familiarity with DevOps practices and CI/CD pipelines, ensuring security and automation are integral to application development and deployment.
  • Excellent communication skills, with the ability to engage both technical and non-technical stakeholders.
  • Proven ability to lead technical discussions and drive decisions in complex, multi-system environments.
