Senior Backend/Data 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 – 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
