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. This is a hands-on delivery role with ownership across the fullstack, from backend APIs and data layers to responsive frontend interfaces. You will work as part of a distributed team with clear accountability for end-to-end feature delivery.

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

Requirements
  • 8+ years of professional experience in fullstack development

  • Strong backend experience with Node.js in production environments

  • Expert-level React.js with a track record of complex frontend delivery

  • Strong proficiency in JavaScript (ES6+) and TypeScript across frontend and backend

  • Hands-on experience with PostgreSQL or MongoDB

  • Solid understanding of REST API design and integration patterns

  • Solid CSS skills including SCSS/SASS

  • Experience with state management (Redux or Context API)

  • Proficiency with Git version control

  • Track record of reliable, consistent delivery in remote teams

  • Strong ownership mentality — you deliver what you commit to

  • Comfortable with structured processes and daily reporting

  • Business-fluent English (written and verbal)

Nice to Have
  • Next.js

  • AWS or cloud platform experience

  • CI/CD pipelines

  • Docker

  • Jest or React Testing Library
