Senior full-stack software engineer

mabl is on a mission to empower software teams with an AI-powered low-code test automation platform that streamlines testing across web, mobile, API, accessibility, and performance. We enable everyone from global enterprises to fast-growing startups to integrate application testing into their development pipelines, accelerating their testing and boosting release cycles, regardless of technical experience.

In 2024, mabl was awarded its 5th AI Breakthrough Award, cementing its position as the #1 AI-powered testing platform in the world. While we continue to grow with the pace of technology, we also believe strongly in the value of culture (our most recent internal survey shows that 92% of our employees feel supported by the flexibility of their work, and 97% believe their manager genuinely cares about their wellbeing.)

To continue delivering on our mission of transforming the testing space, we’re looking for people to join our team of leaders, experts, innovators, and community builders. Our core values are: drive, authenticity, support, and insight; these are the foundation of our culture and a key part of what it means to be a mabler.
