Job Description

Senior Test Analyst – Trading Systems, API, Protocol Testing

Esprow

• Contribute to QA testing efforts of Esprow’s products, with a primary focus on FIX Protocol, trading APIs, and multi-protocol financial systems. • Perform functional, integration, regression, system, and certification testing of trading platforms, web services, and messaging-based systems. • Analyse business and functional specifications of trading systems or matching engines and derive structured test scenarios, validation logic, and detailed test cases directly from them. • Design comprehensive validation strategies across order types, time-in-force rules, trading phases, matching priorities, and negative scenarios to ensure full coverage of exchange and matching engine behaviour. • Create detailed, comprehensive, and well-structured test plans, test cases, and test scenarios aligned with business and technical requirements. • Analyse business and functional requirements to ensure complete test coverage and validate expected system behaviour, including trade lifecycle and post-trade processing. • Analyse test results, logs, message structures, protocol flows, and FIX sessions to ensure software quality and recommend preventive and corrective actions. • Liaise with Project Managers and Development teams to clarify requirements and resolve issues prior to client releases (without acting as a traditional requirements-gathering Business Analyst). • Support client implementation and integration testing activities where required. • Contribute to automation initiatives for API and protocol-level testing where applicable. • Stay up to date with new testing tools, API testing methodologies, and best practices in protocol validation.

Job Requirements

  • 3+ years of experience in QA testing within financial technology, capital markets, or trading system environments.
  • Proven experience working with exchange platforms, matching engines, or electronic trading systems.
  • Experience deriving structured test scenarios and test cases directly from functional specifications of trading systems (e.g., order types, time-in-force, trading phases, matching logic) is strongly preferred.
  • Strong understanding of exchange microstructure, trading workflows, order lifecycle, and matching engine behaviour.
  • Solid understanding of FIX Protocol and/or trading APIs.
  • Practical experience in API and protocol testing using industry-standard tools or frameworks.
  • Strong knowledge of HTTP/HTTPS, RESTful services, JSON/XML, status codes, and API validation techniques.
  • Experience creating and maintaining test plans, test strategies, regression coverage, and release validation documentation.
  • Strong analytical skills with the ability to interpret complex trading rules and translate them into effective validation scenarios.
  • Good understanding of Software Development Life Cycle (SDLC).
  • Fluent English speaking and writing skills.
  • Exceptional attention to detail — ensuring that no trading rule, protocol nuance, or edge case is overlooked.

Benefits

  • Full time position (mix of onsite and remote).
  • Competitive package.
  • Career path in a technology company with many talented people.
  • Opportunity to take more responsibility and gain professional experience in financial markets.
