About the Role
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
EMBARK ON YOUR SPACE44 JOURNEY WITH A FEW SIMPLE STEPS
1. Hireflix Chat (20 min): Share how you work and what matters most to you
2. HR Sync (45 min): Connect your experience with our goals
3. Code Challenge: Complete a 1-2 hour coding session
4. Psychometric Insight: Take a 1-hour assessment exploring your strengths and working style
WORKING MODEL AND BENEFITS
- Flexible Work Schedule: Enjoy a non-linear workday designed to enhance productivity and maintain a harmonious work-life balance, with core hours for team collaboration
- Professional Growth: Access training opportunities to boost your career prospects
- Innovative Projects and Tools: Engage in cutting-edge projects using the latest tools and technologies within a progressive remote work environment
- Competitive Income: Receive competitive compensation with regular performance reviews and potential raises every six months
- Global Team Dynamics: Collaborate with a diverse, international team that values openness and teamwork
- Fully Remote Environment: Work from anywhere with normal business hours and flexibility, no on-call rotation
- Gradual Onboarding: Start with a planned transition as you get up to speed with our systems and processes
