Senior QA Engineers, Nicosia

Trading technology is evolving fast. Bullettech is built to stay ahead of it.

Founded in 2020 and headquartered in Nicosia, Cyprus, we develop high-performance trading software used by professionals across the US markets. Our flagship product, the Nova Trading System, delivers the speed, precision, and reliability that modern trading demands — and we are just getting started.

Beyond trading, we are building next-generation reporting and back-office solutions that bring structure and clarity to complex financial data.

The Opportunity

We are looking for two Senior QA Engineers (manual + automation) to test and validate our high‑end US Equity Trading platform, covering both backend systems (OMS & Market Data) and our desktop frontend application. You will work closely with Developers and Product Owners to ensure reliability, performance, and correctness in a distributed, event‑driven, real‑time environment.

Role Summary

• Design and execute comprehensive test strategies across backend services (OMS, Market Data) and the desktop frontend application, ensuring every release meets the highest quality bar.
• Develop and maintain automated regression suites while performing targeted manual exploratory testing.
• Help define and enforce quality standards for a real‑time trading platform.

Key Responsibilities

• Analyse requirements and user stories to derive clear, meaningful test cases and scenarios.
• Design, execute, and document manual functional, integration, and regression tests across backend services (order lifecycle, routing, execution flows, market data feeds, APIs) and the desktop frontend (order entry, book fetching, layout persistence, pop menu routing, user workflows).
• Develop and maintain automated tests (API, integration, and UI where applicable) as part of CI/CD pipelines.
• Validate the correct handling of order states, failures, edge cases, and exception scenarios.
• Test system behavior under load alongside developers and DevOps to identify performance and stability issues.
• Create and maintain test data sets, including realistic trading and market data scenarios.
• Log, track, and verify defects, working closely with developers to reproduce and debug issues.
• Contribute to improving test frameworks, tooling, and processes for both backend and frontend.
• Collaborate with Product Owners and stakeholders to clarify acceptance criteria and sign off on releases.
• Participate in release validation and post‑release checks in test and production‑like environments.

What You'll Bring

• 3+ years of experience in software testing / QA, with a mix of manual and automation testing.
• Proven experience testing complex backend systems (APIs, services, message‑based or event‑driven architectures).
• Hands-on experience with test automation frameworks and tools for API testing, integration tests, or UI automation.
• Solid understanding of software testing types and practices: functional, regression, integration, system, and exploratory testing.
• Experience working in agile teams (Scrum/Kanban), including working from user stories and acceptance criteria.
• The ability to read and understand technical specifications, logs, and API contracts.
• Comfortable working closely with Developers.
• Sharp attention to detail, systematic thinking, and a proactive attitude towards quality.
• Strong written and verbal communication skills in English.

What We Offer

• Test and validate a high‑end electronic trading platform operating in live markets, where your work has a direct and measurable impact on reliability, performance, and user confidence
• Collaborate closely with skilled C++ Engineers and Product Owners in a fast‑moving, technically demanding environment where quality is taken seriously and great work is noticed.
• Agile delivery, short decision chains, and a low-politics culture. We remove the noise so you can focus on what matters.
• You will have the room to influence tools, processes, and quality standards as we grow.
• A competitive compensation package and clear path into a Senior/Lead QA or QA Automation specialist role as Bullettech grows. The people who join now will shape how quality is defined here.
• On-site, remote, or hybrid — we trust our people to deliver and support them in doing so.
