Node.JS Backend Engineer

About Tessian

Tessian, formerly CheckRecipient, was founded in 2013 to solve the problem of highly sensitive emails being sent to the wrong people. 

Tessian is on a mission to transform the way enterprises secure their communication channels. We build advanced machine intelligence to help organisations protect their communications and filter out threats without them having to define what a threat looks like.

Position

As a member of Tessian's (formerly CheckRecipient) backend-engineering team, you'll be part of a growing division building a dependable infrastructure for processing email traffic in real-time.

First and foremost, we're looking for NodeJS, but you'll also have a keen eye on good developer practices and the wider software technology stack.

You'll be a great thinker, as well as a coder, and you'll have the ability to plan, question, suggest and explain - skills we value as highly as your ability to code! We also place great stock in Agile working, our daily standups, and two 2-hour sessions of Deep Work (no interruptions!).

As part of our team, you'll be working across the board; collaborating with our data scientists who are building new machine learning threat models, architecting our application to scale with our growing client base, diagnosing issues and helping out new team members.

Our technology stack includes Haraka (an open source email server), Docker, AWS/Azure, Postgres and more - you'll be helping to build a new generation of AI-based enterprise security.

Your qualification

• Good knowledge of NodeJS: you know your Promises from your callbacks and you can configure a package.json in your sleep!
• Understanding of how open-source projects work (existing projects or contributions are a plus - please do send us links in your cover letter!) 
• Knowledge of the basics of Docker and why containerisation is useful
• Able to apply software best-practices in application security, including issue tracking, testing, code reviews and more
• Interested in email technologies, protocols, problems and threats
• Willing to learn, build and contribute
