About the Role :

We are seeking a Senior AWS Developer to design and build scalable, secure, and enterprise-grade platforms on AWS. The role goes beyond coding - you will set the technical foundation for user management, API frameworks, data persistence, and security, while leading a team of developers. Our platforms will host advanced use cases, including AI, but your primary responsibility will be ensuring that the underlying cloud architecture is robust, compliant, and future-proof.

Key Responsibilities :

Platform Architecture & Development :

- Architect and implement scalable backend services using AWS (Lambda, ECS/EKS, API Gateway, Step Functions, DynamoDB, RDS, S3, etc.).

- Design and manage API frameworks (REST, GraphQL, or OData) with versioning, throttling, and access control.

- Build and optimise multi-tenant user management systems with fine-grained access control (IAM, Cognito, SSO/SAML).

- Ensure database reliability and performance (DynamoDB, Aurora, caching layers).

- Implement monitoring, logging, and auditing (CloudWatch, X-Ray).

Security & Compliance :

- Enforce secure coding and deployment practices (IAM roles, Secrets Manager, encryption, VPC design).

- Implement data governance and compliance controls (GDPR, SOC2, HIPAA as applicable).

- Drive best practices for API security, authentication, authorisation, and auditability.

- Proactively identify vulnerabilities and ensure platforms meet enterprise security standards.

Team Leadership :

- Lead and mentor a team of AWS developers, enforcing best practices in scalability, performance, and security.

- Define and maintain coding standards, architecture guidelines, and CI/CD pipelines.

- Review system designs and code to ensure they meet long-term platform scalability goals.

Collaboration & Delivery :

- Partner with product managers, architects, and customer teams to align solutions with business needs.

- Translate high-level requirements into scalable, modular architectures.

- Drive cost optimisation strategies across compute, storage, and networking.

Qualifications :

- Bachelor's or Master's degree in Computer Science, Engineering, or equivalent.

- 5+ years in AWS cloud engineering and backend development, with a proven track record of building secure, scalable platforms.

- Strong expertise in user authentication & authorization frameworks (Cognito, SAML, OAuth2, IAM).

- Deep knowledge of API design and management, including API Gateway, throttling, and observability.

- Strong skills in database design & scaling (SQL & NoSQL).

- Hands-on programming experience in Python, Node.js, or Java.

- Familiarity with IaC (Terraform/CloudFormation) and DevOps pipelines (CodePipeline, GitHub Actions, Jenkins).

- Strong understanding of enterprise security best practices in cloud environments.

- Proven experience in team leadership and mentoring developers.

Nice to Have :

- Experience with multi-cloud integration and enterprise systems (e.g., SAP, Salesforce).

- Knowledge of event-driven architectures and messaging systems (SNS, SQS, Kafka).

- Familiarity with AI/ML workloads on AWS (SageMaker, Bedrock) as consumers of the platform.
