We are looking for a Staff Database Engineer to join our team and work on designing, modeling and optimizing OLTP related database technologies (RDMBS and NoSQL); and dive deeper with Application Architects and DBAs to build applications (with tens of millions of active accounts transacting with more than 1000+ tps). Additionally, you'll be working on Data Warehouse solutions (leveraging AWS Redshift, Databricks and others) to build the performant data movement pipelines across OLTP and OLAP and give complete End-to-End coverage of data lifecycle. However, your primary responsibility will remain OLTP focused RDBMS and NoSQL database solutions.

This is NOT a Data Warehouse (or BI/Analytics/ML&AI) focused lead role so please keep this in mind before applying.

Essential functions

Design and development of various data models associated with Relational DBs (MS SQL Server, PostgreSQL, or similar) and NoSQL DBs (Cassandra, Cosmos DB, Dynamo DB or similar)
Ensuring database features and capabilities are incorporated into data model designs to optimize performance, resiliency, and scalability (with tens of millions of active accounts transacting with more than 1000+ tps)
Working closely with other technology leaders to design and develop enterprise-wide data strategy for data modeling, data pipelines, and data integrations across various environments and technology stacks
Developing performant data movement pipelines using real-time event data streams (Apache Kafka, Azure Event Hub, AWS Kinesis, Azure Databricks etc.)
Designing and implementing performant cloud data warehouse platforms (Redshift, Azure Databricks, SQL DW, Snowflake, or similar)
Delivering and presenting proofs of concept to of key technology components to project stakeholders and internal technology leaders
Developing the data architecture and governance models for systems of engagement and provides the framework for integrating source systems with the transactional databases and/or data warehouses; Ensuring data architectural designs are consistent, maintainable, flexible, extensible and cost effective
Ensuring data security and privacy standards are implemented including- role based security, encryption, tokenization, and obfuscation
Performing problem-solving of application issues and production errors, including high level critical production issues that require immediate attention
Work with other technology leaders on setting database standards and best practices for designing and architecting cloud-based data and reporting applications

Qualifications

Minimum 8 years of overall software development experience
Minimum 6 years of hands-on experience in database engineering (RDMBS and NoSQL)
Bachelor's degree in Computer science, Computer Engineering or related field
Experience with RDMBS (primarily MS SQL Server); proficiency with advanced SQL concepts (T-SQL, PL/SQL, etc.) that processes millions of transactions daily with very high processing rates to support mission critical databases
Good understanding of SQL engine internals to help design and tune databases to get the optimal performance
Development experience with NoSQL DBs (Cassandra, Cosmos DB, Dynamo DB or similar); and associated data modeling
Experience in designing, developing, and deploying cloud-based solutions which leverage cloud provided platforms (Azure / AWS)
Development experience with cloud-based data warehouse platform (Azure Databricks, Azure Synapse, AWS Redshift, Snowflake, etc.)
Knowledge of data structures and algorithms and excellent programming skills (.NET, C#, Python and/or Java)
Demonstrated expertise in performance tuning in various DB environments with large volume and velocity of data
Experience working in a Dev/Ops environment with tools such as Azure Dev Ops, Microsoft Visual Studio Team Services, Chef, Puppet or Terraform
Experience in handling structured and semi structured data forms like JSON/XML and normalization of data structures
Understanding of OLTP and OLAP applications

Would be a plus
