The role:
As a Senior Software Engineer, Fullstack, you will be involved in the whole cycle of product development on the web. You will own the B2B platform with authenticated dashboards, complex permissions, subscription flows, regional behavior, and several server-side integrations. Everything you release will reach 500 million of our users, which requires solid focus on the end user experience and usability.
What you’ll do:
- Own features across Vue components, Nuxt pages, layouts, middleware, Vuex modules, and server routes.
- Build operational workflows such as onboarding, account administration, member management, messaging, webhooks, analytics, billing, and verified-business products.
- Design maintainable state and data flows across a large collection of namespaced Vuex modules.
- Integrate multiple REST services, including region-specific endpoints, authentication, CRM, analytics, telecom, and payment providers.
- Maintain authentication flows including OTP, 2FA, trusted devices, secure sessions, permissions, and subscription-based feature access.
- Develop responsive, accessible interfaces with Vuetify and the existing SCSS architecture.
- Write unit, integration, and browser-level tests for critical workflows.
- Diagnose production issues involving browser behavior, APIs, state, permissions, and third-party services.
- Preserve and extend CSP, cookie, CORS, CSRF, and XSS protections.
- Improve the codebase incrementally, particularly JavaScript-to-TypeScript adoption, component decomposition, test coverage, and legacy Vue patterns.
- Mentor engineers, review designs and pull requests, and help establish practical frontend engineering standards.
- Collaborate with product, design, backend, security, QA, and infrastructure teams.
What you bring in:
- 5+ years of web engineering experience, or equivalent demonstrated ability.
- Strong production experience with Vue 3, including Composition API, component lifecycle, composables, reactivity, and reusable component design.
- Production experience with Nuxt 3, including file-based routing, layouts, route middleware, runtime configuration, SSR/client boundaries, and Nitro/H3 server routes.
- Advanced JavaScript and TypeScript skills, including typing asynchronous APIs.
- Experience with complex client-side state management using Vuex, Pinia, Redux, or an equivalent library.
- Strong understanding of HTTP, REST APIs, Axios or Fetch, interceptors, error handling, authentication, token refresh, and multi-service integration.
- Experience building data-heavy B2B interfaces: forms, tables, filtering, pagination, dialogs, file uploads, bulk operations, and multi-step workflows.
- Strong CSS skills, including responsive design, SCSS, Flexbox, Grid, and working within an established component system such as Vuetify.
- Practical web security knowledge covering secure cookies, CSP, CORS, CSRF, XSS, secrets, input validation, and safe third-party script integration.
- Experience testing Vue applications using Vitest/Jest, Vue Test Utils, DOM test environments, and API mocking.
- Ability to independently debug issues spanning the browser, frontend state, server routes, external APIs, and deployment configuration.
- Evidence of technical leadership through mentoring, architectural decisions, code reviews, incident handling, or ownership of major product areas.
- Clear written and verbal communication with both engineering and non-engineering stakeholders.
It would be great if you also have:
- Vuetify 3 and Vuelidate.
- Firebase Hosting and Firebase Cloud Functions on Node.js.
- Internationalized applications using Vue I18n or a similar framework.
- Multi-region, multi-tenant, role-based, or subscription-gated SaaS platforms.
- Payment or subscription systems, particularly Chargebee.
- CRM and customer-platform integrations such as Salesforce, Zoho, CleverTap, GTM, or Vitally.
- Telecom or communications APIs.
- Browser automation with Playwright or Cypress.
- Accessibility testing and WCAG implementation.
- Frontend performance profiling, bundle analysis, caching, and code splitting.
- Experience modernizing a mixed Options API/Composition API and JavaScript/TypeScript codebase without disruptive rewrites.
