Founding Frontend Engineer
Build the interfaces healthcare teams use every day. Real-time dashboards, workflow management, and a design system that makes complex operations feel simple.
What you’ll do
- ▸Build the admin dashboard — the command center where healthcare teams manage patient engagement at population scale
- ▸Create real-time interfaces — live conversation monitoring, campaign progress, team workqueues that update instantly
- ▸Design data-dense experiences — analytics dashboards, patient timelines, performance metrics that surface insights without overwhelming users
- ▸Own the design system — components, patterns, and documentation that accelerate product development across all Rivvi products
- ▸Build for accessibility — WCAG 2.1 AA compliance for healthcare professionals who spend hours in the product daily
- ▸Shape product direction — you'll influence what we build, not just how we build it
Requirements
- ▸5+ years frontend engineering (or 3+ years with MS in CS)
- ▸TypeScript expertise — strict mode, proper typing, building for long-term maintainability
- ▸Next.js 13+ experience — App Router, Server Components, streaming patterns
- ▸Strong CSS fundamentals — Tailwind, responsive design, understanding layout and performance
- ▸UX sensibility — you simplify complex workflows and sweat the details that make products feel great
- ▸Comfort with AI tooling — you use Cursor, Copilot, or Claude daily to move faster
Nice to have
- ▸Healthcare, fintech, or B2B SaaS dashboard experience
- ▸Real-time features (WebSocket, SSE, optimistic updates)
- ▸Data visualization (Recharts, D3.js, or custom charting)
- ▸Design system creation and component library architecture
- ▸Testing experience (Vitest, Playwright, Testing Library)
Why this role matters
Healthcare teams spend their days in our product. The dashboard you build is how care managers see their population, track their campaigns, and know what needs attention. Good UX isn't a nice-to-have — it's the difference between a tool people tolerate and one they love.
We're processing 2M+ patient interactions through interfaces that need to feel fast, clear, and reliable. As a founding engineer, you'll shape what "good" looks like and build the systems that make it possible.
What you'll own
The admin dashboard. This is the product healthcare teams live in. Campaign management, patient engagement tracking, real-time monitoring, team workqueues. You'll own the experience end-to-end — not just implementing designs, but shaping what we build.
Real-time interfaces. When a conversation happens, teams see it live. Transcripts streaming in real-time, status updates flowing through, escalations appearing the moment they're triggered. You'll build interfaces that make real-time feel natural.
Data visualization. Healthcare generates mountains of data. Your job is to surface what matters: adherence trends, campaign performance, patient engagement patterns. Dense information, clear presentation.
The design system. We're building multiple products from shared primitives. You'll create the component library, establish patterns, and write documentation that makes the whole team faster.
What we're building
Rivvi is conversational AI infrastructure for healthcare. We handle the complexity — AI orchestration, data reconciliation, workflow automation — so healthcare teams can focus on patients.
The frontend challenge is translating that complexity into interfaces that feel simple. A care manager with 10,000 patients should open their dashboard and immediately know what needs attention. A pharmacist should see their refill queue and process it without friction. The product should get out of the way and let people do their jobs.
What success looks like
- Healthcare teams describe the product as "fast" and "simple" despite the underlying complexity
- New features ship weekly with consistent patterns and accessibility baked in
- The design system accelerates development — new surfaces come together in days, not weeks
- Engineers across the team build confidently on foundations you create
The team
We're a small, senior team in Kendall Square. You'll work directly with the founders and have real input on product decisions. No layers of approval. No months-long design cycles. Build something, ship it, learn from real users, iterate.
