The project:


Our client is building an AI-powered B2B SaaS platform that helps recurring service companies recover lost revenue and eliminate billing errors.
 

The product automatically reads contracts, compares them with billing data, and guides finance teams to invoice accurately — without spreadsheets or manual checks.
 

The platform is ISO 27001, SOC 2 Type II, and GDPR compliant.

Current stage: MVP refinement and scaling.
 

You will work directly with the CTO and take ownership of the frontend direction as the product evolves.

- Comfortable building real product workflows (tables, filters, roles, statuses, dashboards)

- Experience working with PostgreSQL or relational databases

- Understanding of performance optimization (rendering behavior, lazy loading, bundle size awareness)

- Experience refactoring and improving early-stage/MVP codebases

- Comfortable working in cloud environments (GCP is a plus)

- Ability to understand and collaborate around Python-based data processing (deep Python experience not required)

Soft Skills:
