Senior Full-Stack Developer (Backend-Focused - Technical Team Lead)

We are building InfoLoom, a scalable SaaS platform that helps retailers manage products, catalogs, storefronts, customer inquiries, quotes and online sales from one platform. It will support shared product information, retailer-specific content, supplier data and multiple retailer websites.

We are looking for a hands-on Senior Full-Stack Developer with a strong backend focus to help build core platform features and guide day-to-day engineering work. You will turn requirements into reliable software, work across backend and frontend features, review code, support other developers and help maintain quality, security and performance. This is an engineering leadership role, not a purely managerial position.

Key Responsibilities:

• Lead implementation of secure, maintainable backend modules and REST APIs using Node.js, TypeScript and NestJS.
• Design PostgreSQL schemas, relationships, constraints, indexes, migrations and efficient queries.
• Implement multi-tenant data isolation using server-controlled tenant context, authorization rules, PostgreSQL RLS and tenant-aware database constraints.
• Build the catalog and PIM foundation for global products, retailer-owned products, variants, attributes, brands, categories and retailer catalog overlays.
• Build reliable data pipelines for CSV, XLSX, JSON, XML, APIs and SFTP sources.
• Implement ingestion stages from raw data and observations through validation, normalization, matching, review and catalog publication.
• Develop background workflows, retries, idempotency, transactional outbox processing and scheduled jobs.
• Integrate external services and business systems through secure APIs and webhooks.
• Work with search, caching, object storage and API-driven retailer storefronts.
• Build authentication, authorization, RBAC and platform administration features.
• Collaborate with frontend developers on React/Next.js interfaces, API contracts and integration issues.
• Establish coding standards, review pull requests, mentor developers and help break work into deliverable milestones.
• Write and maintain unit, integration, API and end-to-end tests.
• Investigate application, database, integration and data-processing problems.

During the first development period, you will help deliver:

• Development environment, API foundation, database migrations and CI/CD.
• Trusted tenant context and automated cross-tenant isolation tests.
• Vendor, source, product, variant, attribute and category foundations.
• One complete ingestion path from source data to validated PIM records.
• Tenant catalog selection, retailer overrides, catalog projection and public API.
• Clear API, database, workflow and testing conventions for the engineering team.
