Key Responsibilities

- Design and build high-performance, stateless REST APIs using asynchronous and event-driven patterns for high-volume, low-latency interactions.

- Design decoupled microservices communicating through message queues, event buses, or streaming platforms such as Kafka, RabbitMQ, or Pulsar.

- Architect systems for high concurrency, large payloads, pagination, and version-secure message exchange using Protobuf, Avro, or JSON.

- Deploy and operate services on Kubernetes or ECS, applying Docker containerization, CI/CD automation, observability, and autoscaling.

- Design storage and caching strategies using PostgreSQL, Aurora, MySQL, Redis, Memcached, RocksDB, or DynamoDB, balancing latency, durability, and cost.

- Build backend services using Go or Rust, with Python for orchestration and automation; apply functional, concurrency, and idempotency principles.

- Develop load-testing and benchmarking approaches using Locust, k6, or JMeter; profile systems and optimize CPU, memory, I/O, and garbage collection.

- Establish design standards that improve resilience, observability, maintainability, and scalability.

- Create automated unit, integration,



and black-box testing for asynchronous flows, schema conformance, and payload validation.

- Own API lifecycle and contract management, including backward compatibility, schema versioning,

pagination, partial updates, and modular validation

Qualifications And Experience

- 8 – 11 years of experience designing, building, and operating distributed, asynchronous systems and production-grade applications.

- Strong expertise in REST, gRPC, microservices, message-driven systems, and event-driven architectures.

- Hands-on proficiency in Go, Rust, and/or Python, with experience deploying microservices on Kubernetes or ECS.

- Strong experience with PostgreSQL/Aurora, Redis, DynamoDB, or comparable low-latency storage and caching technologies.

- Working knowledge of Locust, k6, or JMeter, and observability tools such as Prometheus, Grafana, or OpenTelemetry.

- Strong understanding of Docker, CI/CD, DevOps practices, Terraform or other Infrastructure-as-Code tools, and functional, reactive, and concurrent programming.
