Strong Middle / Senior Automation Test Engineer (Python) Job at ELEKS (Ternopil)

Job Description

Our client is a US-based leading national services and online solutions provider to community and regional banks and credit unions. We're looking for someone who pushes testing left rather than waits for tickets, who treats AI tools like Claude Code as a core part of how they work, and who sees a regression suite that has grown organically over time as an opportunity rather than a chore.

Job Responsibility

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
