Job description

Senior QA Engineer

Quality Guard · API + UI + E2E · Performance & Security · AI in Test Automation

At CO3, we are standing up a new engineering team to take technical ownership of a live, active logistics platform integrated into our ecosystem. We need a Senior QA Engineer who is tired of being a passive "ticket-closer" and wants to act as a true Quality Guard — someone who deeply understands existing platform behaviour, prevents bugs before they hit production, and leads quality strategy through system modernization and unification.

Why this role?

• Real Platform Evolution: Take ownership of a live production platform—understanding its current integration layer, maintaining production reliability, and modernizing the stack into CO3’s core architecture.
• Genuine Ownership: Integrations, cloud infrastructure, engineering standards, and the unification strategy are yours to participate in and execute.
• Scale & Ecosystem Variety: Hundreds of active integrations across the logistics ecosystem, handling high throughput and complex data feeds.
• Beyond Basic CRUD Apps: Test complex, high-throughput systems—Kafka streams, telematics feeds, ETL pipelines, and batch file transfers—deeply intertwined with heavy, non-trivial domain logic that actively processes and transforms this data.
• True Autonomy & Scope: Drive quality end-to-end across API, UI, performance, security, and data integrity rather than sitting in a narrow testing silo.

Your mission

• Deconstruct & Guard: Deeply understand existing platform behaviours, edge cases, and data flows to prevent regressions during ongoing maintenance and unification.
• Automate Across the Stack: Build and maintain robust automated test suites (API, UI, E2E) using modern frameworks like Playwright and Karate.
• Verify Complex Data Pipelines: Test diverse integration flows—REST APIs, Kafka streams, ETL batches, and file-based data processing—ensuring end-to-end data integrity.
• Performance & Security: Treat performance and security testing as first-class citizens, verifying system resilience under high logistics data volumes.
• Adopt AI in QA: Integrate AI tooling into test generation, maintenance, and edge-case analysis to accelerate QA workflows.
• Embed Quality Upstream: Collaborate closely with Tech Leads and Devs before code is even deployed to ensure testability and architectural quality ("shift-left" mindset).

What's in it for you

• True Product Ownership: One evolving logistics platform with long-term vision—no body-leasing or agency setup, with a candid, "No-BS" culture.
• High Technical Impact: Your quality strategy directly ensures the reliability of European logistics data streams.
• Modern Stack & AI-Native Culture: Kafka, cloud infrastructure, event-driven architecture, high data volumes and AI integrated into daily workflows.
• Flexibility: Remote-first across Poland with an optional Wrocław office setup (Powstańców Śląskich).
