Job description

Join Full Stack House as a full-stack engineer to help build a modern sports tournament platform (Tournee) and CRM applications on Open Mercato. The position is remote with flexible hours. Both projects already have working code to learn from, and you'll be mentored by a tech lead with 15+ years of experience who cares deeply about code quality and process — protected main branch, PR-based development, CI/CD, and automated tests on every merge.

What you'll do

• Develop Tournee — a SaaS platform for sports tournament organization, with a React Native web + mobile app and a NestJS backend exposing a GraphQL API.
• Build CRM applications on Open Mercato that help businesses manage customer relationships and streamline their workflows.
• Work across the stack — from React / React Native frontends to NestJS backends, GraphQL APIs, and PostgreSQL databases.
• Write maintainable, tested code following modern best practices — automated tests, code reviews, and CI/CD pipelines.
• Collaborate closely with the tech lead and other engineers to design features that deliver great user experiences.

What we're looking for

• Experience with JavaScript and TypeScript.
• Experience in front-end or back-end development (Node.js, NestJS, or similar frameworks).
• Willingness to work across the full stack — you needn't be an expert in both, but be comfortable (or eager to learn) on either when needed.
• Experience with SQL databases (PostgreSQL preferred).
• Experience with git and pull-request-based development.
• Experience writing automated tests.

Nice to have

• React or React Native experience.
• Infrastructure-as-Code experience (Terraform).
