Lead Fullstack Engineer

Tessian protects every business’s mission by securing the human layer 💫

We're building intelligent security that works for human beings as they are , not how security policies would like them to be. Using machine learning technology, Tessian automatically predicts and eliminates advanced threats on email caused by human error - like data exfiltration, accidental data loss, business email compromise and phishing attacks - with minimal disruption to employees' workflow. As a result, employees are empowered to do their best work, without security getting in their way. You can read more about Human Layer Security here .

Tessian has raised a $74m Series C led by renowned security investors, March Capital (Crowdstrike, Knowbe4), with follow-on from Sequoia, Accel, Balderton, Latitude, Okta, Sozo, Citi & Schroder Adveq, to further our mission to secure the human layer.

Founded in 2013, Tessian is backed by world-class venture capital investors, has hubs in London, San Francisco, Boston, and Austin, and London, and is one of the Top-3 2021 Best Places to Work for Women .

At Tessian, we're building the world’s first Human Layer Security platform. We’re making a difference by providing automatic, real-time protection against threats such as social engineering, human error, & data exfiltration, for people all  around the world.

We're looking for backend engineers to build out our platform, drive our ability to scale, and grow with us as a company. You’ll stop criminal threats and prevent embarrassing mistakes for millions of people.

Our high-volume, low-latency backend systems power the whole product. From deploying data science models in production to integrating with our front end, you'll be involved in projects that span all aspects of the business. Our mission critical product and high volumes of data mean you will have many challenging problems to solve.

You’ll be surrounded by incredibly smart, talented and friendly colleagues. Engineers at Tessian love to learn from each other and pull together as a team to succeed. We all have a say in what we build and how we build it and you will be empowered - and encouraged - to have an opinion.

We know that we do our best work and have the most fun as a diverse team that represents our users and the world we live in. We work hard to develop our incredible Tessians and ensure that the Engineering team is a fantastic place to work for every gender, ethnicity, age, race, sexual orientation and educational background. We also seek diversity of experience:some of our engineers have been building distributed backend systems in Python for years, and some have learned the ins and outs of their tech stack and language on the job.
