About the Role

We are looking for an SDE-2 Frontend-leaning Full-Stack Engineer to build the interface of CRM Opportunities, the deal and pipeline engine at the heart of our CRM. Opportunities is the system of record for every revenue motion our customers run, from lead conversion to closed-won, and the pipeline board is where our customers spend their working day.

This role is frontend-first. The hard problems here are interface problems: a drag-and-drop pipeline board that stays smooth with thousands of cards on screen, optimistic updates that roll back cleanly when a write fails, deal detail views assembled from arbitrary customer-defined custom fields, filters and saved views that hold up under real use, and keeping all of it coherent as several people move deals in the same pipeline at once.

You will own frontend features end-to-end in Vue.js, and you will go into the backend as the work requires — extending an API, shaping a response so the client does not have to over-fetch, adding an endpoint that serves the view you are building. You do not need to be a backend specialist; you do need to be unafraid of the server side. Senior engineers own the broader architecture and are there for design guidance and review.

What You Will Do
- Own frontend features across Opportunities in Vue.js — the pipeline board, deal detail views, stage and pipeline configuration, filters and saved views, bulk actions, and reporting surfaces.
- Build interactions that have to feel instant: drag-and-drop stage moves, inline edits, optimistic updates with clean rollback and clear error states when a write fails.
- Make large pipelines fast in the browser — virtualized and windowed lists, pagination and lazy loading, render and re-render cost, bundle size, and time to first meaningful paint on a board with thousands of deals.
- Design and maintain client-side state and data-fetching patterns (Pinia/Vuex, caching, invalidation) so the UI stays consistent without redundant round-trips.
- Handle concurrency in the interface: live updates when a teammate moves a deal, stale-data detection, and sensible conflict resolution.
- Render dynamic, customer-defined schemas — custom fields, custom objects, and per-workspace configuration — without special-casing every variation.
- Build reusable, well-composed components, and contribute to the shared design system rather than growing one-off UI.
- Extend the backend where your feature needs it: adding or reshaping NestJS API endpoints, trimming over-fetching, and adjusting payloads for the view you are building.
- Write tests that matter — component and unit tests, plus end-to-end coverage of the flows customers cannot afford to have broken.
- Instrument the frontend: error tracking, real-user performance monitoring, and the event data needed to see how a feature is actually used.
- Care about accessibility, keyboard support, responsive layout, and cross-browser behavior as part of shipping.
- Take part in on-call for the surfaces you own, debug production issues, and contribute to postmortems; write clear design docs and participate in design and code review.

What You Will Need
- 3+ years building and shipping production frontend applications.
- Strong JavaScript/TypeScript fundamentals, and depth in a component framework — Vue preferred, React fine if you are willing to work in Vue.
- Real experience with complex, stateful interfaces — not just forms and CRUD screens.
- Practical grasp of frontend performance: rendering cost, long lists, network waterfalls, bundle size, and how to profile rather than guess.
- Comfortable consuming and debugging REST APIs, and confident enough in a backend codebase (Node.js/NestJS or similar) to make the change your feature needs.
- Solid CSS and layout skills, and an eye for whether a build matches the design.
- Experience shipping and supporting features you wrote — design through deploy.

Preferred Qualifications
- Built a board, kanban, table, grid, or calendar interface with drag-and-drop and large data volumes.
- Exposure to CRM, sales, pipeline, or workflow products; experience with dynamic or schema-driven UI.
- Worked on real-time or collaborative interfaces (WebSockets, polling, optimistic concurrency); multi-tenant SaaS.
- Familiarity with Vue 3, Pinia, Vite, and end-to-end testing (Playwright or Cypress); backend experience with Node.js/NestJS and MongoDB.
- Product instincts and a portfolio or GitHub of shipped work.

Tech Skill Set: Vue.js (Vue 3, Pinia, Vite), TypeScript, modern CSS — backed by Node.js (NestJS) APIs, MongoDB, and Redis, running on a distributed microservices architecture over Istio service mesh.

The company is an Equal Opportunity Employer.
