Senior Backend/Data Engineer

Remote (CET ±4h)B2B Contract18-23k 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 – RSS feeds, Google News, LinkedIn, job boards, event calendars – and deliver actionable intelligence to sales teams in real-time.

The technical challenge: Building reliable data infrastructure at scale. Web scraping that doesn't break. Pipelines that handle thousands of sources without drowning. Data quality that catches garbage before it hits production. Multi-source orchestration that actually works.

What You'll Own

You'll own our data infrastructure – the foundation that feeds everything else.

In your first month:

  • Walk through the codebase and data architecture with the CPTO
  • Understand our source expansion roadmap and current bottlenecks
  • Ship your first improvement to data acquisition or pipeline reliability

In your first quarter:

  • Own source expansion end-to-end (new data sources, integrations, scraping)
  • Build robust data pipelines with proper error handling and monitoring
  • Improve data quality systems – catch bad data before it pollutes signals
  • Scale background job infrastructure for growing volume

Where we're heading: We want ZYNT to monitor everything relevant – events, job changes, company news, market shifts. You'll build the plumbing that makes this possible: scraping at scale, multi-source orchestration, and infrastructure that doesn't wake anyone up at 3 AM.

The Stack

  • Languages: TypeScript (primary), Python
  • Data: PostgreSQL, pgvector, data pipelines
  • Infrastructure: Cloud (AWS/GCP), Trigger.dev
  • Observability: Structured logging, error tracking

Who You Are

Must have:

  • 3-6 years backend engineering experience
  • Experience building data pipelines or ETL systems in production
  • Web scraping experience (you know why it's harder than it looks)
  • TypeScript and/or Python fluency
  • PostgreSQL proficiency – you can write efficient queries and design schemas
  • Fluent Polish and English (C1+)

The attitude:

  • You build systems that don't need babysitting
  • You think about edge cases before they become incidents
  • "It works on my machine" is not acceptable to you
  • You enjoy making infrastructure invisible (when it works, nobody notices)

Nice to have:

  • Startup or 0→1 experience
  • Background job systems (Trigger.dev, Redis, Celery, or similar)
  • API integrations with third-party services
  • DevOps basics (CI/CD, containers, monitoring)
  • Multi-tenant SaaS background
  • Experience with data quality or validation systems

Why Join Now

You'd be one of our first engineering hires.

  • Early-stage, real ownership: Small team, big problems, no bureaucracy
  • Shape everything: Architecture, processes, culture – it's all being built
  • Customers using the product daily: We're past the "will anyone use this" phase
  • Visible impact: Your work directly enables everything else

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: 18-23k 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 with data systems, our challenges
  3. Practical task – real problem, reasonable scope
  4. Founders conversation – culture, vision, your questions
