Software Engineer In Test

Intro....

MRJ have partnered exclusively with a hyper growth SaaS company embarking on an exciting new AI first journey.

We're working with the CTO to spin out a new 'AI first' team from scratch (Product Lead, Engineers, QA) focussed on building and launching high-impact and groundbreaking AI products & features that will a) take the company to new levels and b) take the market by storm.

"As a founding SDET within this new AI venture, you'll join a high-performing engineering team that is being build from scratch to create innovative AI and LLM products from the ground up. We move fast, build lean, and iterate quickly. If you love solving real problems, experimenting, and shipping impactful products, this one’s for you."

Day-to-day you will.....

• Develop and maintain automated tests and frameworks to ensure comprehensive test coverage of the web apps and APIs.
• Execute automated tests and analyse results to identify defects and ensure product quality.
• Collaborate within the product and development team to understand how features should be tested.
• Work with the development team and AI platform team to troubleshoot and resolve issues promptly.
• Stay updated with the latest industry trends and best practices in software testing and quality assurance.
• Identify opportunities for process improvements and contribute to the enhancement of testing practices, testability, tools, code health and maintainability in collaboration with the wider Quality community.
• Foster a collaborative environment by working closely within cross-functional teams to ensure high-quality software delivery.
• Automate performance and stress testing of the team’s applications.

And it is expected that you will offer:

• Experience with programming/scripting languages (e.g., Javascript & TypeScript).
• Hands on experience automating tests with modern testing tools and frameworks, such as Cypress or Playwright and Postman/Newman.
• Experience working in a fast moving agile environment.
• Experience automating performance and load tests using tools like K6, JMeter or Gatling.
• Experience testing AI driven software where results are often probabilistic rather than deterministic.
