Senior Fullstack Developer (Freelance, Remote)

Senior Fullstack Developer

Company Overview

SPACE44 builds and operates software systems for companies that need technology to work reliably in real, day-to-day operations.

We work as long-term engineering partners, embedding experienced engineers into client environments and taking responsibility for execution, stability, and ongoing improvement of production systems. Our work goes beyond traditional staffing or project delivery — we operate the systems we help build.

SPACE44 is a remote-first company. We value clear ownership, practical problem-solving, and engineers who are comfortable running real systems in production.

Who We Are Looking For

We are looking for a Senior Fullstack Developer to join a client project building and maintaining enterprise web applications.

What You'll Do

• Design, build, and maintain backend services and REST APIs using Node.js
• Develop and maintain frontend applications using React and TypeScript
• Own features across the full stack — from database schema to UI interaction
• Work with relational and/or document databases (PostgreSQL or MongoDB)
• Integrate frontend components with backend services and third-party APIs
• Write clean, well-documented, and testable code across both layers
• Conduct code reviews and provide constructive feedback to peers
• Participate in Agile/Scrum processes including sprint planning and daily standups
• Communicate proactively with team members and client stakeholders
• Log time accurately and maintain clear documentation of work progress
