Expert QA Engineer – Data Platform

Location

Bangalore, India

About Alegeus

Alegeus is the market leader in consumer-directed healthcare (CDH) solutions, powering millions of consumer benefit accounts including FSAs, HSAs, HRAs, dependent care and wellness programs through a modern SaaS and payments platform.

We are investing aggressively in modernization, API-first integration, real-time data access, and AI-enabled automation to redefine how consumers save and spend on healthcare. At this inflection point, we are transforming our platform, elevating engineering rigor, and building a next-generation product and engineering organization.

Role Summary

We are looking for an Expert QA Engineer to ensure the quality, reliability, and correctness of our next-generation Data Platform and Data-Driven APIs.

This role focuses on validating large-scale distributed data systems (Apache Spark), data pipelines, and data-serving platforms (APIs/microservices). You will operate at the intersection of data engineering and quality engineering, building automated frameworks and strategies that ensure data is accurate, complete, and trustworthy at scale.

This is not traditional QA. You will validate systems where failures are often silent—requiring strong analytical thinking, deep data validation skills, and a mindset that treats data correctness as a first-class concern.

Key Responsibilities

Data Platform Quality Engineering

Design and develop scalable data pipelines using Apache Spark (batch and streaming)
Build and maintain data platform layers: ingestion, transformation, and serving
Optimize Spark jobs for performance, cost, and reliability (partitioning, skew handling, memory tuning)
Implement data quality, observability, and lineage frameworks
Contribute to data architecture decisions (Lakehouse, data mesh, storage formats, partition strategies)
Define and enforce data contracts and schema evolution practices

Test Strategy & Automation

Design and implement end-to-end test strategies for ETL/ELT pipelines
Build and maintain automated data validation frameworks (SQL-based, programmatic, or custom tools)
Develop reusable utilities for data comparison, reconciliation, and anomaly detection
Integrate data validation into CI/CD pipelines for continuous quality checks

API & Data Serving Validation

Validate data exposed via APIs and microservices (Java/.NET/Node) for correctness and contract adherence
Perform integration testing across data pipelines and consuming services
Ensure low-latency and high-availability data serving layers meet functional and non-functional requirements

Data Quality, Observability & Monitoring

Define and enforce data quality rules (accuracy, completeness, timeliness, uniqueness)
Implement and leverage data observability tools to detect anomalies, drift, and failures
Validate pipeline reliability, including retry mechanisms and failure recovery
Collaborate in defining SLAs/SLOs for data availability and freshness

Performance & Edge Case Validation

Test pipelines and systems for performance at scale, including large data volumes and concurrency
Validate handling of edge cases such as:

Data skew and partition imbalance
Late-arriving or out-of-order data
Duplicate records and idempotency
Schema evolution and backward compatibility

Collaboration & Product Mindset

Work closely with data engineers, backend engineers, product managers, and analytics teams
Understand business meaning of data, not just structure
Translate business rules into testable validation logic
Participate in design discussions to prevent defects early (shift-left approach)

Required Qualifications (Hard Requirements)

8+ years of experience in QA / Quality Engineering, with strong focus on data platforms or data systems
Hands-on experience testing data pipelines (ETL/ELT) and distributed systems
Strong SQL skills and experience with large-scale data validation
Experience with Apache Spark or similar distributed data processing frameworks
Programming skills in Python / Java / Scala for test automation
Experience validating REST APIs and microservices
Deep understanding of:

Data validation techniques (reconciliation, aggregation checks, anomaly detection)
Data storage formats (Parquet, ORC, Avro)
Data modeling and schema evolution

Experience with cloud platforms (Azure/AWS/GCP)
Familiarity with CI/CD pipelines and test automation frameworks

Preferred Qualifications

Experience with Spark Structured Streaming and real-time data validation
Exposure to Lakehouse architecture (Delta Lake, Iceberg, Hudi)
Experience with data observability tools (e.g., Monte Carlo, Great Expectations, Deequ, etc.)
Understanding of event-driven systems (Kafka, Event Hubs)
Experience with performance and load testing for data systems
Familiarity with Kubernetes and containerized environments

What Success Looks Like

A successful QA engineer in this role will:

Ensure high data correctness and reliability across pipelines and APIs
Build automated validation systems that scale with data growth
Detect and prevent silent data failures and inconsistencies
Collaborate effectively to shift quality upstream into design and development
Improve confidence in data as a trusted product asset

Why join us

You will work on mission-critical data systems where correctness directly impacts financial and healthcare outcomes. This role offers the opportunity to define how data quality is engineered at scale, not just tested.

You will collaborate with strong engineering teams, work on modern data architecture, and help build a platform where data is treated as a product-not a byproduct.

Because We Care, We Offer

A flexible work environment
Competitive salaries, paid vacation, and holidays
Robust professional development programs
Comprehensive health, wellness, and financial packages
