- Mentor engineers, conduct design reviews, and contribute to engineering excellence across teams.
- Collaborate with cross-functional teams; follow Agile/Scrum workflows (tickets, sprints, reviews).
SKILLS
Must have
- Proven experience designing and implementing secure, scalable backend architectures using AWS services (S3, Lambda, DynamoDB, ECS, EC2, etc.).
- Strong proficiency in Python development and object-oriented design principles.
- Hands-on experience with Infrastructure-as-Code tools such as AWS CDK (TypeScript/Python) or Terraform.
- Deep understanding of Docker, containerized development, and microservice deployment patterns.
- Expertise in building REST APIs, microservices, and event-driven architectures.
- Advanced knowledge of relational and non-relational databases, schema design, and query optimization.
- Experience designing ETL/ELT pipelines, data modeling, and implementing data quality frameworks.
- Familiarity with workflow orchestration tools like Argo Workflows.
- Strong capability in CI/CD automation, GitLab, testing frameworks, and enforcing code quality standards.
- Ability to translate complex business requirements into scalable technical solutions.
- Collaborative experience working with frontend, data, QA, and product teams in cross-functional environments.
Nice to have
• Knowledge of EKS (Kubernetes) and container orchestration. • Experience with search engines (e.g., OpenSearch). • Designing ETL pipelines using Athena, OpenSearch, or Redshift. • Exposure to Snowflake, data warehouses, Parquet file processing, and schema evolution. • Familiarity with monitoring and observability tools (Grafana, Tableau, OpenSearch Dashboards).
