Senior Full-Stack Engineer

Remote (CET ±4h)B2B Contract18-22k PLN net/month B2B

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

Why Join Now

You'd be one of our first engineering hires.

  • Early-stage, real ownership: Small team, big problems, no bureaucracy
  • Shape everything: Product direction, component architecture, user experience – it's all being built
  • Customers using the product daily: We're past the "will anyone use this" phase

How We Work

  • Ship daily. We deploy to production constantly
  • Founder-level ownership. You own outcomes, not tasks
  • Direct customer access. You'll hear what users need firsthand
  • Outcomes, not hours. We care what you ship, not when you're online

The Details

  • Compensation: 18-22k PLN net/month (B2B)
  • Equity: Discussed during process
  • Location: Remote, CET ±4 hours overlap required
  • Office: Optional access to Warsaw space

Interview Process

  1. Intro call – mutual fit check
  2. Technical conversation – your experience, our challenges
  3. Practical task – real problem, reasonable scope
  4. Founders conversation – culture, vision, your questions
