(*Note: This is a requirement for one of Uplers' client - Medblocks)What do you need for this opportunity?Must have skills required:Kafka, Snowflake, CI/CD Pipeline, ETL/ELT pipelines, PostgreSQL, BackendMedblocks is Looking for:
As a Principal Engineer at Medblocks, you will be the primary architect of our data infrastructure, designing and implementing the foundation that powers our entire healthcare platform. This is a high-ownership role where you’ll make critical decisions about data architecture, security, and performance that will scale with us for years to come.
Key responsibilities include:
- Architecting and implementing complex PostgreSQL database schemas that handle millions of healthcare records with sub-second query performance
- Writing and optimizing advanced PostgreSQL features including RLS (Row-Level Security) policies, stored procedures, triggers, and custom functions
- Building reliable, real-time data pipelines using CDC (Change Data Capture) and event-driven architectures to sync data across multiple systems
- Designing and implementing database performance monitoring, query optimization, and debugging strategies
- Creating data integration patterns that map between our core PostgreSQL database and external systems (data warehouses, analytics platforms, third-party APIs)
- Establishing database CI/CD practices including migration strategies, testing frameworks, and zero-downtime deployment patterns
- Mentoring team members on database best practices and reviewing critical database design decisions
- Documenting complex data models and creating technical specifications that other engineers can follow
Qualities We Value:
- Deep technical curiosity: You read PostgreSQL release notes for fun and have opinions about indexing strategies
- Systems thinking: You understand how database decisions impact the entire application stack
- Ownership mentality: You’ve been the person others turn to when the database is on fire at 2 AM
- Teaching ability: You can explain why denormalization might be the right choice to both junior engineers and senior architects
- Pragmatism: You know when to use triggers vs application logic, when to normalize vs denormalize
Requirements:
- 5+ years of production database engineering experience, with at least 3 years focused on PostgreSQL
- Proven experience designing complex relational data models (50+ tables) that have scaled in production
- Deep PostgreSQL expertise including:
- Advanced SQL (CTEs, window functions, recursive queries)
- PL/pgSQL programming for procedures and triggers
- Performance tuning (query plans, indexing strategies, vacuum configuration)
- Security implementations (RLS, role-based access)
- Experience building data pipelines and ETL/ELT processes at scale
- Hands-on experience with data integration patterns (CDC, event streaming, batch processing)
- Strong DevOps skills including:
- Database migration tools and strategies
- CI/CD pipeline implementation
- Infrastructure as Code (Terraform, Ansible)
- Containerization and orchestration
- Experience with monitoring and debugging production database issues
- Track record of working in high-autonomy environments where you owned technical decisions
Nice to haves:
- Experience with data warehouse technologies (Snowflake, BigQuery, Redshift, Apache Iceberg)
- Knowledge of event streaming platforms (Kafka, Debezium, Apache Pulsar)
- Familiarity with dbt, Apache Airflow, or similar data orchestration tools
- Experience with time-series data or audit log patterns
- Contributions to PostgreSQL extensions or database-related open source projects
- Experience with multi-tenant database architectures
- Background in regulated industries requiring data compliance
