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 Desktop (C#/.Net) 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 desktop 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.
