Senior Full-Stack Engineer
The Problem
Sales teams spend hours digging through news, LinkedIn, and databases looking for the right moment to reach out. A company just raised funding. A VP just changed jobs. A competitor just expanded into a new market. These signals exist – but finding them manually doesn't scale.
ZYNT surfaces buying signals automatically. We process thousands of sources, extract what matters, and deliver actionable intelligence in real-time.
The challenge: Building the product that turns AI output into action. Real-time dashboards. Self-service configuration. Multi-tenant architecture that works for enterprises. Intelligence is only valuable if people can act on it – and bad UX means signals get buried.
What You'll Build
You'll own the product experience – from database to dashboard.
In your first month:
- Walk through the codebase with the CPTO
- Join a customer call – understand how they actually use signals
- Ship your first improvement to the signal dashboard
In your first quarter:
- Own the signal experience end-to-end (dashboard, filtering, detail views)
- Build self-service configuration – let customers set up their own monitored entities
- Ship the events monitoring interface
- Implement customer onboarding flow
Where we're heading: We want ZYNT to become the default way B2B teams discover opportunities – a platform that sales, marketing, and leadership all rely on daily. You'll help us get there by making complex intelligence feel simple.
The Stack
- Frontend: Next.js 15, React, TypeScript
- Styling: Tailwind CSS, shadcn/ui, Figma
- Backend: Node.js, PostgreSQL, Prisma, REST APIs
- Auth: Clerk (multi-tenant, organization-scoped)
Who You Are
Must have:
- 2-5 years full-stack experience (portfolio matters more than years)
- Strong Next.js/React and TypeScript
- Node.js backend experience – you can build APIs, not just consume them
- Above-average CSS/UI skills – you can take Figma to production with precision
- Eye for design and UX – you notice when something feels off
- Experience shipping complete features end-to-end (not just "contributing to")
- Fluent Polish and English (C1+)
The attitude:
- Your first question is "How will the customer use this?"
- You take features from DB schema → API → UI → production
- You ship MVP, iterate on feedback, don't gold-plate
- You make product decisions, not just implement them
Nice to have:
- Multi-tenant SaaS experience
- Startup or 0→1 background
- Animation/micro-interactions (Framer Motion)
- Enterprise features (RBAC, audit logs)
- Data visualization experience
