We are looking for a Senior Fullstack Developer to build and own customer-facing and internal products end to end. This is primarily a frontend-heavy role — you’ll spend most of your time deep in React, component architecture, and the widgets and apps that customers and agents actually touch — backed by solid Node.js skills to design and own the services those frontends depend on.

You will work in a small, autonomous product team alongside QA and a product owner, shipping features that go to production frequently. This is a hands-on engineering role with real ownership of design decisions, not a ticket-execution role.

Responsibility

- Design, build, and ship complex React UIs — component libraries, embeddable widgets, and full applications — with an eye for performance, accessibility, and reuse.
- Build and maintain embeddable, CDN-distributed widgets (ESM/IIFE) consumed by third-party or partner-facing pages.
- Work with micro-frontend patterns (Module Federation), where a product area is composed of independently built and deployed pieces.
- Author and publish internal npm component and data-provider libraries, with Storybook-driven development so components stay documented and reusable across teams.Design and build the Node.js services your features depend on (Express/Nest/Fastify, or Next.js API routes for lighter cases) — auth, data access, integration with external APIs — owned end to end: design, implementation, tests, shipping it.
- Contribute to architecture discussions and help set technical direction, especially on the frontend/widget side.
- Review peers' code with substance, and raise the quality bar on testing, observability, and maintainability.
- Mentor mid-level and junior engineers,



and work with product/QA to break requirements into deliverable increments, flagging risk early

What we're looking for

REQUIRED

- 5+ years of professional software development experience, with deep, demonstrable expertise in React — this is the core of the role.
- React: strong command of hooks, component architecture, state management, performance optimization, and micro-frontend patterns for composing large applications across teams.
- Solid JavaScript/TypeScript fundamentals — async patterns, module design, error handling, performance.
- Experience shipping embeddable widgets or component libraries consumed outside your own app — CDN-distributed, npm-published, or both.
- Comfortable across UI ecosystems (shadcn/Radix, MUI, Mantine, or similar) and component-driven development with Storybook.
- Solid Node.js proficiency — comfortable designing and building a real service (Express/Nest/Fastify), not just wiring route handlers: request/response, auth, and integrating external APIs (moderate depth).
- Working database skills — can design a reasonable schema and write efficient queries (PostgreSQL/MySQL/MongoDB); deep indexing/optimisation work is not the focus.
- Working exposure to Docker/containers, message queues or event-driven patterns (Kafka, RabbitMQ, SQS), and basic observability tooling — enough to deploy, debug via logs and metrics, and reason about these day to day; deep platform/infra engineering such as Kubernetes administration or distributed-systems design at scale is not expected (moderate depth).
- Practical testing habits, Git-based workflows, code review, and CI/CD.
- Clear written and spoken English, and comfort working with distributed teams across time zones.
