Senior Software Engineer - Data

We are looking for a Senior Software Engineer to join our Data Engineering Infrastructure team, which builds and operates the foundational platforms that power data ingestion, transformation, and analytics across the organization. You will design and develop high-performance, reliable, and scalable systems that enable data engineers, analysts, and ML practitioners to move, process, and govern data efficiently and securely.

Description

As a Senior Software Engineer in the Data Engineering Infrastructure team, you will design and build distributed systems and frameworks that automate the lifecycle of data - from ingestion to transformation to serving. You'll work at the intersection of software engineering, distributed data processing, and cloud infrastructure, helping to define the standards, abstractions, and tools that enable our data platform to operate at scale.

You will collaborate closely with teams across data engineering, analytics, ML, and platform engineering to deliver resilient infrastructure components such as data ingestion pipelines, metadata and schema management services, workflow orchestration, and monitoring frameworks. This is a hands-on role where you will influence architecture, write production-grade code, and drive engineering excellence across the data platform.","responsibilities":"Design, build, and maintain scalable data infrastructure and frameworks supporting batch and streaming workloads.

Experience integrating data platforms with MLOps and machine learning workflows

Active participation or contributions to relevant open-source data technologies or industry communities

Master's or Ph.D. degree in Computer Science, Data Engineering, or a related quantitative field

Minimum Qualifications

12+ years of experience in software engineering, with at least 5 years focused on data systems or platform infrastructure

Proven track record of leading design discussions, mentoring engineers, and driving cross-team technical initiatives

Strong programming skills in Java, Python; Scala - nice to have

Hands-on experience designing, developing, and operating high-performance backend services

Hands-on experience with distributed data frameworks such as Spark, Flink, or Kafka

Solid understanding of data modeling, storage formats (Parquet/Avro/ORC), and partitioning strategies

Experience with data governance, cataloging, and schema management systems (e.g., Hive Metastore, Glue, Iceberg, Delta Lake)

Experience working with cloud-based data platforms (AWS, GCP, or Azure)

Experience building data infrastructure frameworks, SDKs, or shared libraries used by multiple data teams

Familiarity with CI/CD, container orchestration (Kubernetes), and infrastructure-as-code tools (Terraform, CloudFormation)

Excellent problem-solving, debugging, and communication skills
