In this role, you will be building and maintaining a high‑performance internal product and platform centred on Apache Pulsar. You need to design and deliver core messaging services, secure authentication/authorization integrations, service-to-service connectivity patterns, and reliable deployment and operations. This role is hands-on and cross‑functional. You will work across C++, Java, Go, and Node.js. Partner with identity, infrastructure, and application teams to set high standards for performance, reliability, and maintainability. You’ll have a large impact on the success of the entire organization.

What You'll Do:-

• Bachelor’s degree, or higher, in Computer Science or a related technical field

• 3-5 years of building backend/platform software with modern C++ (C++17 and above)

• Built services using messaging/streaming systems (Kafka, RabbitMQ etc)

• Strong knowledge of CI/CD pipelines, Docker and Kubernetes.

• Provide timely support for production issues.

What We're Looking For:-

• Build and operate core messaging capabilities on Apache Pulsar and related technologies.

• Develop a C++-based internal product and shared libraries with emphasis on performance, resilience, and clean interfaces.

• Define and implement cross-language integrations and SDKs (C++, Java, Go, Node.js); establish versioned APIs and schema governance (e.g., AsyncAPI/OpenAPI, Avro/Protobuf).

• Improve Linux-based development and operational workflows: builds (CMake/Bazel), packaging, containerization, and performance tuning.

• Automate deployments and releases with CI/CD and infrastructure-as-code (e.g., GitHub Actions/Jenkins, Docker, Kubernetes, Terraform/Ansible).

• Document designs, review code, mentor peers, and collaborate closely with stakeholders.

Desired Attributes:-

• Strong understanding of concurrency, networking, memory, and performance.

• Hands-on experience with Apache Pulsar or similar messaging/streaming systems (Kafka, RabbitMQ, NATS), including pub/sub, partitions, ordering, idempotency, and delivery semantics.

• Comfortable working across languages (C++, Java, Go, Node.js) and designing cross-language APIs/SDKs.

• Strong Linux fundamentals for development, debugging, and operations; scripting proficiency (Bash/Python).

• Experience with CI/CD, containers (Docker), and Kubernetes fundamentals; sound understanding of secure deployment practices.

• Clear communication, ownership mentality, and ability to drive work from design through production.
