QA Engineer

at Tessian in London

(₤45000 - ₤65000 per year)


At CheckRecipient, we have the ambitious goal of protecting enterprise networks against new and intelligent cyber threats, making it impossible for sensitive information to end up in the wrong hands.

Through advanced machine learning and natural language processing (NLP), CheckRecipient prevents breaches in real-time, outsmarting traditional rule-based, admin-intensive approaches which can only report a breach after it has occurred.

Founded by a team of Imperial College engineers, we’re backed by some of the world’s leading technology investors. We work with international clients in the financial, legal and professional services sectors who trust us to find the most intelligent ways to keep their data secure.

We’ve recently closed a fundraising round of $2.7m led by Accel and LocalGlobe and we are looking to work with the brightest minds to help us accomplish our goal and help us defend our clients against the biggest cybersecurity problems.
