Senior Full-Stack Engineer with Frontend Expertise

Prishtine, Kosovo

About Serus

Serus is a digital privacy platform operated by ANON AI Labs Inc. The position is part of ANON AI Labs and is centered mainly on developing and enhancing Serus.

The platform monitors the open web, data brokers, and breach sources to identify where personal information is exposed, and then supports users in having that information removed. A key challenge is presenting highly complex intelligence in a way that feels simple, clear, and reliable, which is reflected largely through the user interface.

The team is small and holds a high standard, placing equal importance on the way products are built and on their final functionality.

About the position

The company is seeking an engineer whose main strength is frontend development, while also being comfortable contributing on the backend. Most of the work will focus on the React application, creating dashboards, workflows, and data visualizations that make complicated exposure data understandable and actionable for users, while also delivering full features across the stack when needed.

This is a role with end-to-end ownership. The person in this position will help shape the UX, challenge weak patterns, and pay close attention to details such as empty states, loading states, motion, accessibility, and i18n that distinguish a refined product from an average one.

What you'll be doing

Create dashboard features and detailed views around complex user-facing data
Develop interactive visualizations along with graph-based and flow-based interfaces
Build advanced forms, multi-step processes, and guided user journeys throughout the product
Work on interfaces that handle real-time and streaming experiences
Maintain a shared design system and component library used across the web application and internal tools
Deliver full-stack functionality from end to end, including API endpoints, data models, and background jobs whenever a feature requires them

Requirements

Several years of experience building production React applications with TypeScript
Strong judgment in component architecture, with a preference for composition over prop-heavy patterns, CSS over JS when appropriate, and avoiding unnecessary abstractions
Solid command of TanStack Query/Router or closely comparable alternatives
Ability to build demanding product elements such as tables, forms, drag-and-drop interactions, and data visualizations while keeping the experience fast
Previous backend delivery experience, including endpoints, a relational database, and an ORM, with confidence working in that area
Strong design and UX sense, with attention to spacing, empty states, and transitions
Ability to write clean, readable code and participate effectively in direct code review
Comfort working asynchronously within a small team

Our stack: React 19 + TypeScript, Vite, TanStack Router/Query/Form/Table, Tailwind + shadcn/Radix, Zustand, Framer Motion, Recharts, React Flow, Storybook. Backend: Hono, Drizzle + Postgres, Zod, Trigger.dev, Clerk, Stripe, Vercel AI SDK. Turborepo + pnpm monorepo, deployed on Fly.io and Cloudflare Pages.

It is not necessary to know every part of the stack from the first day, but strong depth in React/TypeScript and the ability to reason within a typed full-stack codebase are expected.

Nice to haves

Experience working in a monorepo environment with Turborepo, pnpm workspaces, or similar tools
Experience with data visualization or graph layout using tools such as D3, ELK, dagre, or React Flow
Experience building real-time UI with websockets, streaming, or optimistic updates
Experience creating AI-powered product capabilities such as chat, streaming, or tool use
Experience with i18n at scale, accessibility, or component development driven by Storybook
Reverse engineering experience
Interest in privacy, security, or OSINT

About the team

The team is small, senior, and operates with minimal process. People are expected to take ownership of features from start to finish and have meaningful input into how the product is built. Quality standards are strict: the team prefers reuse before creating something new, favors platform capabilities before adding extra JavaScript, and keeps changes focused on a single purpose.

Our values

Quality is essential, and craftsmanship matters just as much as delivery
Reuse before building and keep solutions straightforward
Take ownership of work from beginning to end
Communicate directly, kindly, and asynchronously
