Adverity is seeking a Quality Engineer to own quality signals for a product pod, combining technical testing expertise with curiosity about how software fails.

Key responsibilities include: - Design and maintain automated test coverage across unit, integration, and end-to-end tests as part of the shared codebase - Build and maintain tooling for fast, reliable feedback including CI pipelines, test environments, synthetic data, and monitoring hooks - Identify gaps in test coverage before they become incidents and make data-driven cases for closing them - Surface risk clearly to enable confident shipping decisions - Bring user perspective into planning conversations, flagging edge cases and failure modes early - Lead root-cause analysis on production issues within the pod's quality domain, focusing on systemic fixes - Track quality trends (flakiness, escaped defects, time-to-detect) and feed into prioritization - Pair with engineers on testing strategy to spread testing skills across the pod - Build features and fix bugs alongside the team This is a full-time, hybrid role based in Sofia with an expectation to be in the office three times per week. Requirements: - Proven experience in a quality or test engineering role on a product engineering team, or equivalent software engineering experience with strong testing focus - Track record of building automated test coverage in production codebases - Experience building or maintaining CI/CD pipelines and test infrastructure (GitHub Actions, Jenkins, CircleCI) - Experience leading or contributing to root-cause analysis on production incidents - Solid coding ability in Python, strong enough to write production code rather than just test scripts - Ability to design test strategy for features from scratch, knowing what to automate versus explore manually - Working knowledge of testing types relevant to the product (API, load/performance, data pipeline testing) - Familiarity with monitoring and observability tools (Datadog, Grafana) to build signal into dashboards
