Backend Data Engineer

Join a SaaS/technology and information industry client team that is developing an AI-based tool to support B2B sales!

RESPONSIBILITIES

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, multisource orchestration, and infrastructure that doesn’t wake anyone up at 3 AM.

REQUIREMENTS

Must have:

• 3-6 years backend engineering experience

• Experience building data pipelines or ETL systems in production

• Experience in working with AWS or GCP Cloud

• 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+) - our customers and team speak both

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

WHAT DO WE OFFER ON THIS PROJECT?

• Cooperation based on a B2B contract

• 100% remote work 

• The support of a dedicated mentor. In the relationship, we focus on direct communication. When you join speedapp, you will be put in touch with a dedicated mentor who will make sure that you enjoy working with us and with the client

• Events and integration meetings, as well as participation in various initiatives, e.g., sports

• Access to the benefits offering (medical care, life insurance, Multisport card).
