What you’ll bring

• 2+ years of hands-on experience in full-stack development.
• Proven expertise with React (hooks, component architecture, state management) and modern JavaScript/TypeScript.
• Solid experience building RESTful services in Node.js with Express (or similar).
• Familiarity with AWS fundamentals (EC2, Lambda, load balancing, caching layers).
• Comfortable with Git, GitHub and automated CI/CD pipelines (e.g., GitHub Actions).
• Self-motivated, proactive and enthusiastic about learning new technologies and sharing knowledge with the team.
• Clear, concise communication skills—vital for an all-remote environment.

Nice-to-haves

• Experience with infrastructure-as-code (Terraform, CloudFormation, CDK).
• Exposure to containerisation (Docker, ECS, EKS) or serverless architecture patterns.
• Prior work in health-tech or other regulated domains.
