About The Position

Join Nomura's Global Markets IT team at the forefront of transformational change in capital markets technology. Our group maintains mission-critical infrastructure for OMS/EMS, Pricing, and Position Marking across listed derivatives trading operations. This is not a conventional testing role—you'll be building the quality infrastructure that powers real-time trading systems used by sales, trading desks, compliance, middle office teams, and external clients worldwide. This is a highly demanding, fast-paced role in an environment that has fundamentally transformed how the bank builds software, pivoting to modern architecture patterns, cloud-native infrastructure, and continuous delivery practices. You'll be at the intersection of financial markets and engineering excellence, where downtime is measured in millions and quality is non-negotiable.

Requirements

Programming proficiency: Strong command of Python, Java, C#, or JavaScript/TypeScript—you write production-quality code, not just test scripts
Testing expertise: Deep understanding of unit, integration, API, contract, and end-to-end testing trade-offs; experience with testing frameworks (pytest, JUnit, TestNG, Jest, Cypress)
DevOps & CI/CD: Hands-on experience with Docker, Kubernetes, Jenkins, GitHub Actions, or GitLab CI; comfortable with infrastructure-as-code
Understanding of order management systems (OMS), execution management systems (EMS), or FIX protocol
Familiarity with listed derivatives (options, futures), pricing models, or position-keeping concepts
Experience testing low-latency, high-throughput systems where performance and correctness are critical
Quality ownership: You see quality as a team responsibility, not a gatekeeper function
Velocity mindset: You thrive in fast-paced environments and enable rapid, safe deployments
Curiosity: You ask 'why' and dig into system behavior, architecture decisions, and trading workflows
Modern engineering practices: You're excited about cloud-native architecture, microservices, event-driven systems, and observability
Bachelor's or Master's degree in Computer Science, Engineering, or related field
0–3 years of professional experience in software development, SDET, or quality engineering roles
Demonstrable coding ability through personal projects, open-source contributions, or internships
Strong problem-solving skills and ability to learn complex domain concepts quickly
Excellent communication skills—you'll be working across technology, trading, and business teams
