AI Tester

DeepLight AI is a specialist AI and data consultancy with extensive experience implementing intelligent enterprise systems across multiple industries, with particular depth in financial services and banking. Our team combines deep expertise in data science, statistical modeling, AI/ML technologies, workflow automation, and systems integration with a practical understanding of complex business operations. At DeepLight, we don't believe in "off-the-shelf" fixes. We deliver tailored AI solutions designed to integrate seamlessly into existing enterprise architectures, ensuring that innovation is both scalable and secure. From building robust data foundations to deploying sophisticated AI platforms, we empower our clients to lead in an increasingly automated world. The AI Tester is a specialized, senior-level quality engineering position within the Testing work pillar. This role is responsible for driving end-to-end quality assurance, test automation strategy, and advanced validation frameworks across complex web interfaces, microservice APIs, and cutting-edge, AI-driven systems. Operating at the intersection of traditional software testing and advanced machine learning engineering, this position focuses heavily on validating distributed backend architectures, streaming data workflows, and Generative AI/LLM outputs to ensure exceptional systemic reliability, accuracy, and performance. Your responsibilities as the AI Tester include: Designing, building, and maintaining scalable, robust end-to-end automation frameworks from scratch, utilizing Playwright as the primary automation engine across web interfaces. Authoring and executing comprehensive API testing suites to validate distributed microservices, ensuring strict data integrity, state consistency, and schema compliance. Designing validation strategies for asynchronous, event-driven data architectures, tracking messages and auditing system behaviors across Kafka-based streaming pipelines. Establishing specialized testing methodologies to evaluate Generative AI and Large Language Model (LLM) outputs, assessing models for hallucination, bias, semantic accuracy, and safety constraints. Managing, curating, and version baseline prompt validation datasets and ground-truth test collections to ensure consistent benchmarking of AI system performance. Partnering closely with AI research engineers, product owners, and DevOps squads to integrate automated testing gates directly into modern CI/CD deployment pipelines. As an AI consultancy, our greatest asset is the expertise of our people. While technical mastery is the foundation of what we do, the ability to bridge the gap between complex data science and actionable business value is what defines your success with Deeplight. We're looking for individuals who are not only world-class in their fields of specialism, but also compelling communicators and persuasive advocates for their own skills. You will be the face of our firm, tasked with building trust, articulating the "why" behind your technical decisions, and effectively "selling" your vision to high-level stakeholders. If you thrive on the challenge of presenting cutting-edge solutions as much as you do on building them, you will fit right in.
