As a Senior AQA/SDET Engineer you will be responsible for building and maintaining automated testing solutions for APIs, integrations, and data pipelines, ensuring the accuracy and integrity of large-scale data flows, and contributing to the evolution of automation frameworks and QA practices.

Responsibilities:

— Design, develop, and maintain automated tests for backend services and data-processing systems in the financial market data domain.
— Build API, integration, and data validation test coverage using C#/.NET automation.
— Validate correctness, completeness, and consistency of historical market data across APIs, databases, files, scheduled jobs, and downstream consumers.
— Automate regression checks for data pipelines, including data ingestion, transformation, storage, caching, and delivery.
— Create reliable test coverage for edge cases related to market dates, historical prices, corporate actions, missing data, delayed data, and incorrect calculations.
— Integrate automated tests into CI/CD pipelines and improve test reporting, stability, and execution reliability.
— Analyze failed tests and production-like issues using logs, monitoring tools, API responses, database queries, and configuration.
— Collaborate with developers to improve testability, observability, and reliability of backend/data services.
— Maintain test documentation, automation coverage notes, and clear defect reports.

Requirements:

— 5-8+ years of AQA/SDET experience testing complex backend, API, data-heavy, or distributed systems.
— 3+ years of hands-on test automation experience with C#/.NET.
— Strong experience designing automation strategy, not only writing individual tests.
— Proven experience building or improving automated test frameworks, CI/CD test stages, reporting, and quality gates.
— Strong API and backend test automation experience.
— Solid SQL and PostgreSQL experience, including advanced queries, data validation, and investigation of data inconsistencies.
— Experience testing data pipelines, scheduled/background jobs, file processing, caching logic, and service-to-service integrations.
— Ability to independently investigate production-like issues using logs, metrics, monitoring dashboards, API responses, database state, and service configuration.
— Strong test design skills: regression strategy, risk-based coverage, boundary cases, negative scenarios, data-driven tests, and clear defect reporting.
— Experience mentoring other QA/AQA/SDET engineers or improving team-level QA practices.
— Understanding of backend architecture, environment-based configuration, service health checks, and deployment validation.
— Experience working in Scrum or another Agile delivery process.
— Languages: Ukrainian native/fluent and English Intermediate or higher.

Nice to Have:

— Experience with financial systems, trading platforms, market data, historical data, or time-series data.
— Experience with ReportPortal, FluentAssertions, NUnit, or desktop UI automation.
— Ability to read or debug C++, Go, or Python code.
— Experience with time-series databases, Kubernetes/Nomad, Grafana, Prometheus, VictoriaMetrics, Elasticsearch, or Kibana.

What do you expect the new hire to accomplish in their first 90 days?

— Become familiar with the financial market data domain and the team’s backend/data-processing workflows.
— Become productive in the existing C#/.NET test automation framework.
— Understand the key historical data flows and the main quality risks around data correctness, completeness, and availability.
— Add automated coverage for critical API, integration, and data validation scenarios.
— Improve regression coverage and contribute to more reliable release validation for the team.
