Type:
Full-time

Location:

About the Role

SaaS Universe is a white-label, multi-tenant SaaS platform that lets agencies launch and resell their own AI-powered SaaS business. The platform covers modules for Agencies, Sub-Accounts, Finance (billing, invoices, subscriptions), Ops Hub, Platform Operations, and an embedded AI-driven QA Console.

We're hiring a senior developer to take ongoing ownership of the application: maintaining code quality, hardening security around multi-tenant data isolation, extending features, and managing releases.

Responsibilities
- Own the day-to-day technical health of the platform: bug fixes, performance, and uptime.
- Maintain and extend multi-tenant architecture — agency/sub-account hierarchies, roles and permissions, and strict data isolation between tenants.
- Build and maintain billing/finance features (subscriptions, invoices, expenses) with a payment provider such as Stripe.
- Integrate and maintain AI/LLM-powered features (streaming responses,



AI composer components) within the QA Console and other modules.
- Manage the Supabase backend: database schema, Row-Level Security policies, Auth, and Edge Functions.
- Work efficiently inside an AI-assisted development workflow — review, refactor, and harden AI-generated output for production.
- Manage deployments, environments (test/production), and domain/infrastructure configuration.
- Write and maintain tests; support the existing QA process.
- Communicate clearly on progress, risks, and technical tradeoffs.

Must-Have Requirements
- 4+ years qualified full-stack development experience.
- Strong React + TypeScript skills; comfortable reading and refactoring AI-generated codebases.
- Hands-on experience with Supabase (or equivalent Postgres + Auth + RLS backend).
- Experience building or maintaining multi-tenant SaaS applications, including data isolation and role-based access control.
