Fullstack Engineer (Node.js / React.js)

We at Mria Labs are developing products for the Atlassian marketplace, and we are currently looking for a talented Node.js / React Engineer to join our team.

Core (must-have)

• 5+ years of professional TypeScript experience across frontend and backend
• 5+ years of React.js, with deep understanding of hooks, context, and component composition
• Strong TypeScript fundamentals (generics, decorators, reflect-metadata, strict mode)
• MobX experience
• TanStack React Query (or strong Redux-Toolkit Query / SWR background — server-state separation matters)
• Solid HTML/CSS, styled-components or another CSS-in-JS library
• Form-heavy app experience with Formik + Yup (or React Hook Form + Zod)
• Node.js (24.x) backend development
• SQL (MySQL dialect, TiDB) — schema design, query optimization, migrations
• Experience with an ORM/query-builder like Drizzle, Prisma, TypeORM, or Knex
• REST APIs and async/event-driven processing (message queues, scheduled jobs)
• Git, code review discipline, GitLab CI/CD pipelines
• Jest + React Testing Library; ability to write integration tests over mocks
• English — Intermediate (B1) or higher

Strongly preferred

• Atlassian Forge platform experience (forge/resolver, forge/sql, forge/kvs, forge/bridge, async events, scheduled triggers) — this is the single biggest differentiator
• Atlaskit / Atlassian Design System component library
• Jira REST API / Confluence API integrations
• Vite build pipeline
• IoC / Dependency Injection with InversifyJS
• Class-based DTO validation: class-validator + class-transformer
• Rich-text editor work with Lexical (or Slate/ProseMirror)
• Charting with Chart.js / react-chartjs-2
• Bulk import/export pipelines, XLSX/CSV parsing
• Sentry for error monitoring; SonarCloud for code quality
• Luxon (or date-fns) for timezone-aware date handling

Nice to have

• Experience building Rovo AI agents or other LLM-tool integrations (Atlassian AI platform)
• Drag-and-drop UX with atlaskit/pragmatic-drag-and-drop
• Pre-commit tooling: Husky, lint-staged, Knip (dead-code detection)
• Multi-tenant SaaS experience (workspace isolation, RBAC)
• CRM / sales-pipeline / lead-management domain knowledge

Responsibilities:

• Developing new user-facing features using React.js;
• Improving current functionality;
• Building reusable components and front-end libraries for future use;
• Translating designs and wireframes into high-quality code;
• Optimizing components for maximum performance across a vast array of web-capable devices and browsers;
• Collaborating with cross-functional teams to define, design, and ship new features;
