• Define and enforce technical standards, design patterns, and best practices across development, security, and application architecture.
• Build and manage CI/CD pipelines to enable efficient and reliable software delivery.
• Drive observability practices using tools such as Datadog and Grafana to monitor application and infrastructure health.
• Collaborate with distributed teams and cross‑functional stakeholders to translate requirements into scalable, user‑centric solutions delivered on time.
• Design and manage AWS infrastructure to support highly available, low‑latency application workloads.

Must Have Skills

• Strong hands‑on experience with Golang/Python for backend development and JavaScript/TypeScript for frontend development, with solid proficiency in HTML5 and CSS for building responsive, user‑centric interfaces.
• Strong experience in API lifecycle management, including schema design, versioning, throttling and payload optimization.
• Proficiency in Angular for building responsive, scalable front‑end applications as part of a full stack development environment.
• Deep understanding of SOLID principles, dependency injection, and robust error handling patterns.
• Strong hands‑on experience with AWS services – AWS Lambda, SQS, SNS, EC2, S3, RDS, API Gateway, VPC, EKS, ECS, IAM, CloudWatch and cloud‑native application design.
• Strong experience with relational databases (e.g., PostgreSQL, MS SQL) and NoSQL databases (e.g., DynamoDB).
• Strong hands‑on experience with event‑driven architectures and message brokers (e.g., Kafka, RabbitMQ).
• Hands‑on experience building distributed systems on AWS and containerization using Docker.
• Hands‑on experience with CI/CD tools (e.g., Jenkins, GitLab CI).
• Experience with observability platforms such as Datadog, Prometheus, or equivalent.
• Strong understanding of cloud security best practices including IAM, encryption, vulnerability management, and compliance controls.

Qualifications

• 5+ years of full‑stack or software engineering experience, with at least 3+ years in full stack development.
• 3+ years of hands‑on experience building full‑stack applications, including backend development (Golang/Python, APIs, microservices) and frontend development using JavaScript/TypeScript frameworks, with strong experience integrating UI layers (e.g., Retool or similar low‑code platforms) with distributed, event‑driven systems on AWS and Kafka.

Nice to Have

• AWS certifications such as AWS Certified Solutions Architect – Associate, AWS Certified Developer, or equivalent.
