[Remote] Database Engineering Intern – PostgreSQL & Microservices

🌍 Remote, USA 🎯 Full-time 🕐 Posted Recently

Job Description

Note: The job is a remote job and is open to candidates in USA. Marketeq Talent is building a backend system designed to evolve from a modular monolith into a microservices architecture. The internship focuses on analyzing, documenting, and restructuring database architecture while providing hands-on experience in real-world system design and data architecture.

Analyze the existing database schemas used by the NestJS backend and Strapi CMS
Document table ownership by backend module (logical microservice boundaries)
Define and document which backend modules own which tables, which modules/services are allowed to read or write specific data, and future target databases for each logical domain
Help restructure tables within the existing databases to align with microservices architecture without breaking existing code
Assist in designing safe migration strategies, including:
Incremental migrations
Temporary compatibility layers (e.g., views or aliases where appropriate)
Rollback considerations
Build developer-facing database documentation, including:
Schema dictionaries
ER diagrams
Naming conventions
Data lifecycle and retention rules
Collaborate with backend engineers to map:
Tables → modules
Modules → future microservices
Help establish internal standards so future schema changes follow a clear, documented process
