Fullstack developer
A fast-growing SaaS team is looking for a senior full-stack developer to help scale their platform and ensure long-term stability. The role spans the fullstack from infrastructure and backend systems to modern frontend development. The developer will contribute to new features, improve system resilience, and mentor teammates while helping to shape architecture and streamline engineering practices.
Ideal candidates have strong experience with TypeScript and Go (including frameworks like Express), PostgreSQL, RabbitMQ, and Neo4j. On the frontend, they should be comfortable with React, Redux, RxJS, and WebSockets. Familiarity with AWS, Kubernetes, GitOps workflows, and DevOps tooling is essential. Excellent communication and a collaborative mindset are key, along with several years of hands-on experience in similar roles.
Experience in smaller product teams, AI-assisted development, or graph-based data modeling is a plus.
This team embraces an AI-native development philosophy—pairing modern tools with clean, maintainable code, lean documentation, and a focus on developer productivity through thoughtful automation and collaboration.
