If you thrive in a collaborative environment that values openness, innovation, and high standards, we’d love to hear from you.

Primary Responsibilities:

• Data & Reporting Ownership: Take ownership of a multi-tenant reporting architecture (currently 16 pools with individual tenant databases, over 3000 tenants), ensuring stability, accuracy, and high performance for millions of processed records.
• Migration Strategy: Architect and execute the long-term migration of legacy reporting systems (MSSQL/SSRS) into our modern core infrastructure (NodeJS/Aurora MySQL/AWS) with the potential to introduce Quicksights, Redshift or other technology.
• Data Pipelines & ETL: Build, maintain, and scale robust ETL processes, data replication processes, and data sync engines utilizing batch processing and parallel execution chains.
• Database Optimization: Identify and address performance bottlenecks using advanced database performance strategies like index optimization, denormalized columns, and rollup tables.
• API Development: Design and build data-intensive, scalable REST APIs that power core SaaS reporting features without relying on excessive external API calls.
• Cross-functional Collaboration: Collaborate closely with Product to translate reporting requirements into technical implementation plans. Work with Frontend Engineers to ensure smooth delivery of data visualizations.
• Code Quality: Participate in code reviews, write automated integration/unit tests, and ensure backend code and data models follow modern best practices.

Skills & Competencies:

• Database Performance: Proven ability to manage massive data volumes (millions of records). Strong understanding of indexing, stored procedures, denormalization strategies, and creating rollup tables for reporting.
• Advanced SQL & MySQL: Deep expertise in MySQL and writing highly performant, direct SQL code. Must be comfortable with advanced concepts including complex Joins, Subqueries, Dynamic SQL, and Common Table Expressions (CTEs).
• ETL & Data Sync: Extensive experience building ETL processes, data replication, and high-volume data synchronization engines.
• AWS Cloud Ecosystem: Experience working with AWS cloud services, specifically Aurora Serverless, DynamoDB, Lambda, and SQS.
• NodeJS & JavaScript: Proficiency with NodeJS (Express/Fastify), JavaScript (ES6+), and asynchronous programming patterns.
• ORM Experience: Experience working with modern ORMs (like Sequelize) while knowing when to bypass them for raw SQL performance.
• System Migration: Demonstrated experience modernizing legacy databases or migrating complex architectures into modern cloud ecosystems.
• Detailed-Oriented: A strong sense of ownership for data integrity, code reliability, and accuracy in a product environment.
• Communication: Excellent verbal and written communication skills to collaborate effectively across engineering and product teams.
• User first: A deep empathy for the user and a desire to learn about how they use Commerce7.

Minimum Qualifications:

• 5+ years of experience in backend software engineering with a direct focus on database architecture, data processing, ETL, and reporting systems.
• Strong proficiency in JavaScript (ES6+) and NodeJS (Express, Fastify, AWS Lambda).
• Advanced hands-on experience with MySQL, modern ORMs (e.g., Sequelize), and writing optimized raw SQL.
• Direct experience working with AWS cloud services (Aurora Serverless, DynamoDB, SQS).
• Demonstrated track record of executing database migrations or legacy system modernizations (experience with MSSQL, SSRS, or PowerShell is a strong advantage).
