Frontend Developer (React)

full-time CheckRecipient London

The Role

We’re looking for a Frontend Developer to help us rethink the CheckRecipient dashboard. We are building an Enterprise dashboard that sits on top of our machine learning platform that our clients can use to configure our various products as well as query the threats we’ve detected. You should be comfortable with Javascript, SQL and a frontend framework (ideally React). If youre also able to use a little python to plug our frontend into our backend thats a huge plus!

Youll get to work on designing and developing a brilliant and complex React app from scratch.


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.

Were delighted to announce that CheckRecipient has been selected to join the Microsoft Accelerator. The programme, which will begin in October, will provide us with unprecedented access to top Microsoft partners and customers, powerful business connections, and world-leading technical knowledge.

Engineering At CheckRecipient

Dealing with massive datasets at scale requires ingenuity and strong analytical skills. Our agnostic approach to problem solving means we favour hiring engineers who pride themselves on the ability to learn new skills, their comfort with the unknown and their willingness to experiment.

At CheckRecipient you’ll be growing your skill-set on an ongoing basis; regular and continuous development is something we believe in and as an employee we will seek to create opportunities for you to evolve.

We build quickly and follow both agile and continuous delivery paradigms. As a member of the CheckRecipient engineering team, you will have the autonomy to work on your own projects, and be part of our regular round tables to bounce ideas around as a team on how to tackle our biggest challenges. We believe in Deep Work and ensure our Engineers have the option of two 2-hour uninterrupted sessions a day with no external distractions.
