Long Description

Day-to-Day Responsibilities

• You and your value stream will be responsible for the full development lifecycle of product and tech roadmap projects and production incidents support.
• You will be working in an agile environment, using Scrum.
• You are expected to work with team OKRs, KPIs and exercise an agile mindset, with a focus on continuous improvement and short feedback loops.
• You will own quality end-to-end - from design and code review all the way through to deployment and production monitoring - with no handoffs to a separate QA team.
• You will design, build, and maintain automated test frameworks and test suites across all levels of the testing pyramid: unit tests, component tests, integration tests, and end-to-end tests.
• You will actively participate in code reviews, sprint planning, and architectural discussions, bringing a quality and risk perspective to every conversation.
• You will think adversarially: challenge happy-path assumptions, probe edge cases, simulate failure scenarios, and surface defects before they ever reach production.
• You will implement and own quality gates in the CI/CD pipeline, ensuring automated checks are part of every merge and every release.
• You will be building and deploying the applications using automated pipelines, so you are expected to have knowledge of Jenkins or any other CI/CD tool along with DevOps work experience.

Who Are We Looking For

We are looking for a Software Development Engineer in Test (SDET) - a fully hands-on engineer who treats quality as an engineering discipline, not a phase at the end of development. People who can drive positive change, step up and show what's next - people with passion, can-do attitude and a hunger to learn and grow:

• At least 3 years of relevant work experience of Agile testing in Scrum in complex environments.
• Strong software engineering skills - you can write, review, refactor, and debug code at the same standard expected of a software engineer.
• Strong experience working in a DevOps environment.
• A genuine testing mindset: you think in failure modes, edge cases, and adversarial scenarios - you actively look for what can go wrong, not just whether the happy path works.
• Proven experience applying the testing pyramid in practice: unit, component, integration, and end-to-end tests - understanding when and why to use each level.
• Strong hands-on experience in using at least one tool for:
• API Testing: XML/JSON, Postman, REST API
• Test Automation: Deep understanding of Test Framework Design
• Programming / scripting languages: Java (primary), SQL
• CI/CD: Jenkins, GitLab
• Non-Functional / Performance Testing: Security, Performance (Jmeter / Gatling / Locust)
• Test reporting and defect tracking: Jira & Confluence
• Hands-on experience of the testing lifecycle, testing pyramid spread across different test environments, functional & technical testing, performance testing, and regression testing.
• Strong knowledge of SQL and Databases (Oracle / SQL Developer).
• Strong knowledge of Linux and CLI.
• Experience in the financial industry and/or e-commerce business is an advantage.
• Google Cloud, Kubernetes, Docker, and Kafka knowledge is an advantage.
• ISTQB / T-MAP certification is an advantage, but is not a substitute for hands-on engineering and automation experience.
