Software Development Engineer in Test

Samba is a media intelligence company. We know what the world is watching, reading, and thinking about — in real time, at scale, across every screen. Our data exists with the consent of over a billion people, organized into the most complete picture of consumer attention ever built. The biggest brands in the world use that picture to make smarter decisions. We think it’s the most interesting data asset on the planet, because it’s the most culturally relevant.  Based in the beautiful city of Porto, you’ll be part of our collaborative Engineering & Development teams, working closely with your peers and decision-makers to maintain and develop our global services and products.   As an SDET, you are a developer with a passion for quality. You won't just find bugs; you will build the tools and systems to prevent them. You will design and implement the custom testing tools and test cases required to validate new features before they ever hit production.   You will be an integral part of the development cycle, responsible for white-box testing and code reviews, aiming to improve the codebase and ensure seamless production releases.   Working within an agile team, you’ll encounter exciting technical challenges and a culture where you’ll always have your voice heard. You'll be working with colleagues from around the world, in a truly worldwide company. If you have a thirst for knowledge and are just as pedantic about clean code as we are, then read on! WHAT YOU'LL DO

Full-Stack Testing: Write and execute test cases (unit, integration, and stress tests) ensuring backend and frontend components are production-ready.

White-Box Exploration: Dive into the application code to understand how features work under the hood, allowing you to design more effective tests.

Tooling & Innovation: Develop and evolve internal tools and utilities needed to test complex new features or code changes.

Automation Development: Write and maintain automated test scripts to cover new features, helping us move away from manual verification.

Debug & Investigate: Identify the root cause of failures by analyzing logs and stack traces, reporting bugs with high-quality technical detail.

Feature Collaboration: Participate in Scrum ceremonies, asking the "what if" questions during refinement to help the team spot edge cases early.

Testbed Support: Assist in maintaining our testing environments.

Code Quality: Participate in code reviews to ensure changes are maintainable and that error handling is robust.

Continuous Learning: Work closely with Senior SDETs and Developers to learn how to architect scalable test suites and manage CI/CD pipelines

WHO YOU ARE

The Foundation: You hold a degree in Software Engineering, Computer Science, or have a similar technical background. You have a solid grasp of Object-Oriented Programming (OOP) and modern software architecture.

Technical Curiosity: You are a natural problem-solver who enjoys deconstructing complex systems to see how they work (and how they might break).

The "Puzzle Solver" Mindset: You aren't satisfied with knowing that something broke; you have the technical curiosity to find out why it broke and how to prevent it from happening again.

Agile Mindset: You thrive in a collaborative environment. You understand that "Agile" isn't just a set of meetings, but a mindset of continuous improvement, flexibility, and delivering value in iterative cycles.

Language Agnostic: While we primarily use .NET/C# (and knowing it well is a major plus!), we value core engineering principles above all. If you are proficient in another language (like Java, Python, or C++) and are eager to learn our stack, we want to hear from you.

Scripting Skills: You are comfortable working in a terminal and have experience with (or a strong interest in) scripting languages like PowerShell or Bash to automate repetitive tasks.

Git Fluent: You are comfortable with version control (Git) and understand the workflow of branches and pull requests.

Great Communicator: You have strong conversational English skills (written and spoken) and enjoy working in a multicultural environment.

Quality Advocate: You believe quality is a collective responsibility and are "pedantic" about clean, maintainable code.

Previous experience in a Software Developer or QA Engineer role (including internships or significant academic projects) is considered an advantage.
