Strong Middle / Senior Automation Test Engineer (Python)

About the Position

ELEKS Quality Assurance Office is looking for a Strong Middle / Senior Automation Test Engineer (Python) in Kyiv, and Western Ukraine.

About the Project

Our client is a US-based leading national services and online solutions provider to community and regional banks and credit unions.

Responsibilities

• Strengthen and extend our automated regression framework so the team can trust the results on every nightly run - assess the current state, propose a path forward, and execute.
• Push testing left: when a nightly regression catches a defect, drive a unit or integration test to catch the same class of problem on the next build.
• Build and maintain unit, integration, and end-to-end tests across our stack - Python test framework, C# APIs running in Azure, SQL and MongoDB.
• Own the quality of the numbers, not just the code - build golden-master and tolerance-based tests for the financial calculations at the heart of BASIS and AtlasOne, where a basis point of drift in a projection is a defect that needs to be caught.
• Own the CI/CD quality gates - decide what blocks a merge, what blocks a release, and how flaky tests get quarantined rather than ignored.
• Treat performance as a quality attribute - stand up performance regression coverage for calc-heavy paths so we catch slowdowns the same week they’re introduced, not the quarter a client notices.
• Close the loop with production - work alongside the team to monitor Azure alerts, logs, and traces; investigate escaped defects from production support tickets; and feed what you find back into the right test layer.
• Develop, document, and execute functional and regression tests across both the established BASIS desktop client and the growing web-based experience that is replacing it; help us continually improve how we automate testing across both applications as the platform evolves.
• Use AI tools like Claude Code to expand coverage, generate test scaffolding, and continuously sharpen our QA process.
• Help raise the floor on what “tested” means across the team - partner with developers on testable design, review test code in PRs, and share what you learn so quality becomes a shared discipline.
• Diagnose application issues using browser dev tools (Chrome, Edge) and database tooling (SQL, MongoDB).
• Manage story and bug tickets from creation through closure.
• Collaborate with business analysts and developers to refine requirements before they become defects.
• Participate in Agile ceremonies - standups, planning, grooming, retros - but expect those to feel more like working conversations than process for its own sake. We’re a tight-knit team that values people who reach out, ask questions, and enjoy collaborating.
• Serve as second-level support for internal user questions and issues.

Requirements

• 4+ years of software quality assurance experience.
• Strong coding skills in Python, with the judgment to recognize test code that needs work and the skill to improve it.
• Experience designing automated test frameworks, not just writing tests inside someone else’s framework.
• Proven experience testing RESTful web services and web applications in a cloud environment (Azure preferred).
• Comfort working across the test pyramid - unit, integration, and end-to-end - and a clear opinion on where each layer earns its keep.
• Comfort reasoning about numerical correctness - tolerances, golden masters, and regression of calculated outputs, not just HTTP 200s.
• Working knowledge of CI/CD pipelines (Azure DevOps or similar) and a point of view on what belongs in pre-merge vs. nightly vs. release gates.
• Awareness of security and compliance considerations in financial software - authorization testing, dependency scanning, and careful handling of sensitive data in test environments.
• A habit of measuring quality - escape rate, flake rate, coverage trends - and using those numbers to drive decisions.
• Familiarity with Selenium WebDriver, Postman, or equivalent tools (BDD/Gherkin/Cucumber is a plus).
• Genuine curiosity about AI-assisted development tools and a track record (or strong desire) to apply them to QA work.
• Excellent communication - you’ll push back on developers, ask hard questions in grooming, and explain quality tradeoffs to business stakeholders.
• A quality mindset that goes beyond test execution - you care about where a bug should have been caught, not just that it was caught.
• Bachelor’s degree in Computer Science, Mathematics, Business, or related discipline.
• Intermediate high level of English.

Nice to Have

• Experience modernizing or evolving an existing automated test framework.
• Experience with Playwright or modern web E2E tooling (we’re open to evolving past Selenium).
• Experience with contract testing (Pact or similar) for API surfaces shared between clients.
• Experience testing calculation engines, pricing engines, or risk models where numerical accuracy is the product.
• Familiarity with the business model of a community bank or credit union.
• Financial solutions or financial analysis background.
• Experience with Claude Code, Copilot, or similar AI development tools applied to testing.

We Offer

• Close cooperation with a customer.
• Challenging tasks.
• Competence development.
• Ability to influence project technologies.
• Team of professionals.
• Dynamic environment with low level of bureaucracy.
