We are looking for a Senior Fullstack Software Developer (React, Node.js, TypeScript) to join our engineering team. In this role, you will be responsible for designing, developing, and delivering end-to-end features across the full stack, contributing to the creation of scalable, high-quality, and production-ready web applications.
If you are passionate about modern web development, product-focused engineering, and building robust systems that scale, this opportunity is for you.
What you will be doing
* Own and deliver features end to end, from data modelling and API design to user-facing interfaces.
* Design and implement scalable and maintainable systems using TypeScript across both backend and frontend.
* Build, maintain, and evolve backend services using Node.js, APIs, databases, and background workflows, with a strong focus on performance, reliability, and data integrity.
* Develop high-quality frontend experiences using React, optimising rendering performance, state management, and overall user experience.
* Collaborate closely with product, design, and AI-focused teams to integrate AI-powered capabilities into production systems.
* Translate product requirements and ambiguous problem statements into well-architected technical solutions.
* Define, implement, and uphold engineering standards, including testing strategies (unit, integration, end-to-end) and observability (logging, monitoring, analytics).
* Conduct code reviews and contribute to architectural decisions and critical feature designs.
* Identify bottlenecks, bugs, and technical debt, proposing and implementing effective solutions.
* Act as a product-minded engineer, collaborating with product and design to shape solutions and challenge assumptions when appropriate.
What we are looking for
* Bachelor's degree in Computer Science, Engineering, or a related field.
* Several years of hands‐on experience building and operating production-grade web applications and distributed systems.
* Strong, hands‐on experience across the full stack, including:
- Backend: Node.js, API design, relational and/or NoSQL databases
- Frontend: React, modern CSS, state management
* Deep expertise in TypeScript, with a strong focus on type safety, maintainability, and developer productivity.
* Proven ability to work autonomously and take ownership of complex features from concept to deployment.
* Strong product and UX sensibility, balancing quality with efficient delivery.
* Comfort working in fast‐paced, evolving environments and collaborating across engineering, product, and design teams.
* Curiosity and enthusiasm for AI‐assisted development workflows and modern web platforms.
* Full professional proficiency in English.
* Availability to start within 30 days (maximum notice period).
Plus (not required but valued)
* Experience with relational databases such as PostgreSQL.
* Familiarity with event‐driven or asynchronous architectures.
* Experience building platforms, marketplaces, or extensible application ecosystems.
* Knowledge of frontend architecture trade-offs (SSR vs SPA, performance optimisation, SEO).
* Exposure to DevOps practices and tooling (Docker, Kubernetes, monitoring/observability).
* Interest or experience in Web3, blockchain, or decentralised/sovereign web technologies.
Why join us?
* Build and ship end‐to‐end features with real product ownership.
* Work in a collaborative, high‐performing engineering team.
* Develop modern, scalable web platforms used in real‐world production environments.
* Continuous learning and professional growth opportunities.
* A culture that values quality, autonomy, and continuous improvement.
