Job description

When 5% of Indian households shop with us, it’s important to build data-backed, resilient systems to manage millions of orders every day. We’ve done this – with zero downtime! 😎 Sounds impossible? Well, that’s the kind of Engineering muscle that has helped Meesho become the e-commerce giant that it is today. We value speed over perfection, and see failures as opportunities to become better. We’ve taken steps to inculcate a strong ‘Founder’s Mindset’ across our engineering teams, making us grow and move fast. We place special emphasis on the continuous growth of each team member - and we do this with regular 1-1s and open communication. Tech Culture We have a unique tech culture where engineers are seen as problem solvers. The engineering org is divided into multiple pods and each pod is aligned to a particular business theme.

Being a consumer app, these systems have SLAs of ~10ms ● Our distributed scheduler tracks more than 50 million shipments periodically fromdifferent partners and does async processing involving RDBMS. ● We use an in-house video streaming platform to support a wide variety of devices and networks. ### What You’ll Do - Design and implement **scalable and fault-tolerant data pipelines** (batch and streaming) using frameworks like **Apache Spark**, **Flink**, and **Kafka**. - Lead the **design and development of data platforms and reusable frameworks** that serve multiple teams and use cases. - Build and optimize **data models and schemas** to support large-scale **operational and analytical** workloads. - **Deeply understand Apache Spark internals** and be capable of modifying or extending the **open-source Spark codebase** as needed. - Develop **streaming solutions** using tools like **Apache Flink**, **Spark Structured Streaming**. - Drive initiatives that **abstract infrastructure complexity**, enabling **ML, analytics, and product teams** to build faster on the platform. - Champion a **platform-building mindset** focused on **reusability**, **extensibility**, and **developer self-service**. - Ensure **data quality, consistency, and governance** through validation frameworks, observability tooling, and access controls. - Optimize infrastructure for **cost, latency, performance**, and **scalability** in **modern cloud-native environments**. - **Mentor and guide junior engineers**, contribute to architecture reviews, and uphold high engineering standards. - Collaborate cross-functionally with product, ML, and data teams to align technical solutions with business needs. ### What We’re Looking For - **5-8 years** of professional experience in software/data engineering with a focus on **distributed data systems**. - Strong programming skills in **Java**, **Scala**, or **Python**, and expertise in **SQL**. - At least **2 years of hands-on experience** with big data systems including **Apache Kafka**, **Apache Spark/EMR/Dataproc**, **Hive**, **Delta Lake**, **Presto/Trino**, **Airflow**, and **data lineage tools** (e.g., Datahb,Marquez, OpenLineage). - Experience implementing and **tuning Spark/Delta Lake/Presto** at **terabyte-scale** or beyond. - Strong understanding of **Apache Spark internals** (Catalyst, Tungsten, shuffle, etc.) with experience customizing or contributing to open-source code. - Familiarity and worked with modern open-source and cloud-native data stack components such as: - **Apache Iceberg**, **Hudi**, or **Delta Lake** - **Trino/Presto**, **DuckDB**, or **ClickHouse,Pinot ,Druid** - **Airflow**, **Dagster**, or **Prefect** - **DBT**, **Great Expectations**, **DataHub**, or **OpenMetadata** - **Kubernetes**, **Terraform**, **Docker** - Strong **analytical and problem-solving skills**, with the ability to debug complex issues in large-scale systems. - Exposure to **data security, privacy, observability**, and **compliance** frameworks is a plus. ### Good to Have - Contributions to open-source projects in the **big data ecosystem** (e.g., Spark, Kafka, Hive, Airflow) - Hands-on **data modeling** experience and exposure to **end-to-end data pipeline development** - Familiarity with **OLAP data cubes** and BI/reporting tools such as **Tableau, Power BI, Superset, or Looker** - Working knowledge of tools and technologies like **ELK Stack (Elasticsearch, Logstash, Kibana)**, **Redis**, and **MySQL** - Exposure to backend technologies including **RxJava**, **Spring Boot**, and **Microservices architecture**
