Solutions Architect

Solutions Architect to design, build, and lead the architecture of cutting-edge fintech solutions using modern cloud platforms, with a strong emphasis on security, scalability, and performance. The ideal candidate will have significant hands-on experience with ReactJS, Java Spring Boot, AWS, and Azure Cloud, as well as a strong background in networking, secure coding practices, integrations, and system debugging.

Solutions Architect will be responsible for defining the technical architecture across cloud platforms, ensuring adherence to security best practices (e.g., OWASP Top 10) and integrating complex systems with modern API-driven and cloud-native approaches. They will also mentor the engineering team, conduct code reviews, and ensure that the architecture supports both functional and non-functional requirements.

Key Responsibilities:

1. Architectural Design & Leadership:
   - Define the system and application architecture for large-scale, cloud-native fintech solutions using ReactJS (front-end) and Java Spring Boot (back-end).
   - Design highly available, scalable, and secure solutions using AWS and Azure cloud platforms, ensuring optimal use of cloud services.
   - Ensure architecture is secure by design, addressing security vulnerabilities like the OWASP Top 10 and applying public/private key encryption principles.
   - Provide hands-on architectural leadership and mentoring to the development teams, ensuring adherence to architectural standards and best practices.
2. Cloud Architecture & Infrastructure:
   - Design and manage cloud infrastructure on AWS and Azure, including EC2, S3, Lambda, RDS, Azure VMs, AKS (Azure Kubernetes Service), and cloud-native services.
   - Implement secure, scalable networking solutions across hybrid cloud environments, including VPCs, VPNs, firewalls, load balancing, and DNS management.
   - Ensure cloud deployments are optimized for cost, performance, and reliability, and implement monitoring solutions using CloudWatch, Azure Monitor, or equivalent.
3. Code Review & Quality Assurance:
   - Lead in-depth code reviews to ensure adherence to best coding practices, performance optimizations, and security guidelines.
   - Provide expert guidance on refactoring, optimization, and debugging to improve code quality across ReactJS and Java Spring Boot stacks.
   - Enforce best practices for secure coding and system design to mitigate potential security risks and vulnerabilities.
4. Security & Encryption:
   - Implement strong security measures, including public/private key encryption, data encryption at rest and in transit, secure authentication protocols (OAuth, JWT, etc.), and token management.
   - Design and implement secure communication protocols between microservices and external systems using SSL/TLS.
   - Ensure the platform adheres to regulatory standards in fintech, such as PCI DSS, GDPR, and OWASP guidelines.
5. Systems Integration:
   - Design and implement seamless integrations between internal microservices and external systems, such as payment gateways, identity providers, and third-party APIs.
   - Build highly efficient, scalable, and secure RESTful APIs and ensure their reliability under heavy workloads.
   - Integrate cloud services across AWS and Azure for multi-cloud or hybrid-cloud environments and ensure smooth data flow between these systems.
6. Debugging & Problem Resolution:
   - Serve as a technical expert in identifying and resolving complex bugs and performance issues, both in development and production environments.
   - Utilize deep knowledge in networking, cloud platforms, and microservices architecture to troubleshoot system bottlenecks, latency issues, and failures.
   - Implement logging, monitoring, and alerting systems to detect and diagnose issues proactively.
7. Networking & Cloud Security:
   - Architect secure and efficient cloud networking infrastructures, including virtual private networks (VPNs), firewalls, and load balancers.
   - Manage IAM (Identity and Access Management) roles, permissions, and policies on AWS and Azure to ensure least-privileged access.
   - Apply OWASP Top 10 security controls across all application layers, ensuring security by design.
8. Continuous Improvement & Collaboration:
   - Collaborate with DevOps and cloud teams to automate infrastructure, CI/CD pipelines, and deployment strategies on AWS and Azure using tools like Terraform, Ansible, and Jenkins.
   - Drive continuous improvement efforts in technical design, performance, security, and reliability, introducing new technologies and solutions where appropriate.
   - Communicate complex architectural concepts and designs to stakeholders, including product managers, business leaders, and technical teams.
