Technical Architect

Technical 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.

The Technical 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.
