About Role

This is a high-impact, hands-on engineering role owning the core data systems that power our

analytics, AI, and automation stack.

You’ll work closely with the CTO and Engineering Leads and independently manage large,

high-throughput data pipelines that process millions of events.

Responsibilities :

• Build and maintain high-throughput, real-time data pipelines using Kafka/Pulsar with Spark,
  
  
  

Flink, and distributed compute engines.

• Design fault-tolerant systems with zero-data-loss principles — checkpointing, replay logic,
  
  
  

DLQs, deduplication, and back-pressure handling.

• Implement data observability — quality checks, SLA alerts, anomaly detection, lineage, and
  
  
  

metadata insights.

• Design and manage Iceberg-based lakehouse tables (Polaris/Gravitino catalogs, schema
  
  
  

evolution, compaction).

• Build fast OLAP layers using ClickHouse / StarRocks.
• Model data across bronze → silver → gold layers for downstream teams.
• Migrate and modernize legacy pipelines into scalable, distributed workflows.
• Orchestrate ETL workloads using Airflow, DBT, Dagster, SQLMesh.
• Optimize SQL transformations and distributed execution across Trino/Spark.
• Ensure strict security and governance across all data layers — access control, encryption,
  
  
  

auditability.

• Collaborate with backend, analytics, and platform teams for seamless data delivery.
  
  
  

Core Technical Skills

• Extremely strong SQL — window functions, query planning, optimization.
• High comfort working with distributed & parallel workloads.
• Hands-on experience with some-many of these technologies : Apache Spark, Apache Flink,
  
  
  

Trino, Apache Kafka, Apache Pulsar, Apache Beam

• Advanced experience in Python (preferred) or Java (strong fundamentals).
• Strong understanding of Parquet, Apache Iceberg, and Iceberg REST catalogs (Polaris /
  
  
  

Gravitino).

• Experience with OLAP databases — ClickHouse / StarRocks.
• Experience with semantic layers — Cube.js or similar.
• Strong experience building pipelines with Airflow, DBT, Dagster, SQLMesh.
  
  
  

• Solid understanding of data structures & algorithms — sorting, searching, memory models.
• Strong grasp of OLTP vs OLAP, indexing, query execution, and storage formats.
• Ability to debug distributed systems end-to-end (compute, storage, network, orchestration).
• Familiarity with cloud environments, containerization (Docker), and monitoring.
• Experience with large-scale data — high throughput, billions of rows, large parallel workloads.
• Awareness of cost optimization in compute & storage.
  
  
  

• Experience with emerging stream processors — Dagster, RisingWave, Arroyo.
• Kubernetes, Terraform, or cloud-native big-data stacks.
  
  
  

• Strong ownership — takes systems from design → build → monitor.
• Self-driven, independent, and comfortable making technical decisions.
• High attention to reliability, data accuracy, and operational excellence.
• Naturally grows into broader technical responsibility as the platform scales.
  
  
  

• High-trust, no-politics culture — we value communication, ownership, and accountability
• Collaborative, ego-free team — building together is in our DNA
• Learning-first environment — mentorship, peer reviews, and exposure to real business impact
• Modern stack + autonomy — your voice shapes how we build
• VC-funded & scaling fast — 250+ strong, building from India for the world
