You will work closely with stakeholders, designers, and fellow developers to deliver robust, scalable, and maintainable solutions using modern JavaScript frameworks and headless CMS platforms.

Responsibilities

• Architect and develop web solutions and applications using JavaScript (TypeScript, ES6+), decoupled/headless CMS platforms (with a focus on Sanity CMS), and modern frameworks (e.g., Next.js, React).
• Design and implement content models, schemas, and editorial workflows within decoupled CMS environments.
• Integrate headless CMS platforms with APIs and third-party services to deliver dynamic, composable digital experiences.
• Collaborate with cross-functional teams to translate business requirements into technical solutions.
• Communicate software design and architecture through technical diagrams, documentation, and presentations.
• Identify, manage, and balance non-functional requirements such as performance, security, usability, maintainability, and scalability.
• Mentor junior developers and contribute to the evolution of development practices and processes.
• Participate in code reviews, provide constructive feedback, and ensure adherence to best practices.
• Proactively identify and manage risks, dependencies, and changes in project scope.

• Minimum 5 years of professional experience in JavaScript development, with at least 2 years specializing in decoupled/headless CMS solutions (Sanity CMS experience strongly preferred).
• Proven experience building and deploying composable architectures and web applications using headless CMS platforms, Next.js, and related technologies.
• Strong understanding of decoupled CMS concepts, content modelling, and API integrations.
• Proficiency with modern development workflows, version control (Git), and CI/CD pipelines.
• Familiarity with AI-assisted development tools (e.g., Cursor AI, GitHub Copilot, etc.) to enhance development throughput, code quality, and overall capabilities.
• Excellent communication skills, both verbal and written, with the ability to explain complex technical concepts to diverse audiences.
• Bachelor’s degree in Computer Science or a related field, or equivalent experience demonstrated through personal projects, open source contributions, or proven advanced knowledge and skills via technical assessments.
• Ability to work collaboratively in a remote, distributed team environment.
• Commitment to inclusive, accessible, and sustainable software development practices.

• Ability to work a maximum of +/- 3 hours from EST.

• Guaranteed 100% remote work—forever.
• Comprehensive wellness support, including access to counselors, crisis support, nutritional coaching, and virtual healthcare.
• Ongoing professional development: training budgets, conferences, certifications, and in-house mentorship.
