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.
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.
Client-side Engineering at Tessian
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 are looking for C# engineers to help build out our integration offerings supporting our next stage of growth, 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.
In Client-side Integrations we hope to demonstrate to our clients that enterprise software can be done differently. We aim for a minimal-disruption approach to tackling email-based threats and we need our software - and our developers working on our client-side integrations - to enable this. Most enterprise clients access their emails via Microsoft Outlook, so our Outlook add-in is a key integration, and the developer in this role will be working on the product at the very heart of our company. 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 Windows desktop and services for years, and some have learned the ins and outs of their tech stack and language on the job.
As a Tessian Client-side Engineer you will:
Design and build reliable client-side systems that operate in a multitude of customer environments.
Monitor and support our deployments to 100,000s (scaling to millions) of users worldwide
Work closely with our other product teams to support and provide input on new features
Tackle the challenges that come with processing highly sensitive data
Value security, stability and good architecture over box-ticking
Make your mark on ambitious projects
Have a passion for creating software that truly provides value to its users
Our Client-side tech stack includes
