* Develop and evolve the platform’s architecture with a focus on scalability, security, reliability, and operational maturity.
* Build and maintain automation for infrastructure provisioning, CI/CD pipelines, monitoring, and IAM.
* Define platform APIs and integration patterns to streamline adoption by internal development teams.
* Ensure compliance with frameworks and standards including ISO27001, SOC2, and DORA.
Technical Leadership & Strategy
* Manage and mentor a multidisciplinary team of cloud engineers and architects.
* Own the platform roadmap, aligning infrastructure goals with product and business strategies.
* Provide expert guidance through architecture reviews, mentoring, and code quality practices.
* Drive engineering best practices around deployment, testing, observability, and security.
* Continuously evaluate and adopt emerging technologies and patterns to improve platform reliability and velocity.
Collaboration & Delivery
* Partner with engineering leaders and product managers to deliver core infrastructure capabilities.
* Collaborate closely with security, compliance, and operations teams to ensure audit readiness and policy alignment.
* Work with development teams to ensure platform services are reliable, well-documented, and easy to integrate at scale.
What You’ll Bring
* Proven leadership in platform engineering within fintech, SaaS, or regulated environments.
* Deep experience delivering production-grade Kubernetes-based platforms on AWS.
* Strong grasp of cloud-native architecture, including high availability, security, and cost-efficiency.
* Familiarity with event-driven system design and microservice patterns.
* Proficient with infrastructure as code (e.g., Terraform, CloudFormation) and CI/CD tooling.
* Hands-on experience with container orchestration (Kubernetes).
* Knowledge of service mesh architectures, API gateways, and secure service-to-service communication.
* Strong experience with observability tools like OpenTelemetry, Prometheus, Grafana, and Datadog.
* Expertise in IAM and authentication protocols such as OAuth2, OIDC, and SAML.
* Solid coding/scripting skills (e.g., Python, Go, TypeScript).
* Excellent leadership, communication, and mentoring abilities.
* Comfortable working in a fast-paced, mission-driven, and collaborative environment.
