- Partial failures
- Retries, timeouts, and idempotency
- Horizontal scaling
- Experience with message brokers and async communication (Kafka, RabbitMQ, SQS, etc.)
- Understand consistency models, eventual consistency, and data replication
DevOps / Cloud
- Work in cloud environments (AWS / Azure / GCP)
- Containerize services using Docker
- Deploy using CI/CD pipelines
- Understand Kubernetes concepts (pods, services, autoscaling) or managed alternatives
- Collaborate with DevOps/SRE on observability, logging, and monitoring
Technical Leadership
- Act as technical owner for backend systems
- Mentor senior and mid-level engineers
- Set engineering standards and best practices
- Work closely with product and business stakeholders to translate requirements into technical designs
