Platform 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

Tessian is looking for skillful Platform engineers (or Linux Systems Administrators interested in making the leap) to with us on our predominantly Cloud deployments. You should be experienced with (and excited by!) ideas like infrastructure as code and "cattle not pets", and be prepared to design, develop and support the various offerings of our system. Because of the sensitive nature of our work flexibility is a must. We deploy to AWS today, but may want to extend to other cloud offerings in the future.

We are extensively using Docker to manage our application code, so this role gives a chance to build on modern software deployment techniques, and we use a range of cloud services to orchestrate, secure and manage our application stack. You'll be investigating and proposing microservices architectures and coming up with new ways to deploy and scale Tessian's platform.

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. 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.

This role may involve, at times, client side visits.

Some of the technologies we’re working with include Node.js, C#, Python, Postgres, MongoDB, Spark, and our current cloud stack revolves around AWS, Docker (on ECS), Ansible and Terraform.

We'd love to meet someone who

• Is a great problem solver who takes pride in their work
• Enjoys building scalable and resilient systems
• Has strong experience managing a range of production applications in a distributed and highly available cloud services environment (AWS preferable)
• Has experience with containerization (Docker) and high level container orchestration systems (e.g. ECS/Kubernetes/Swarm)
• Has experience with automation and configuration management tools (e.g. Ansible, Terraform, and Puppet)
• Has a deep understanding of Linux operating system and administration skills, and shell-scripting skills
• Has a deep understanding of server/network security concepts and implementations
• Has created and worked with microservice infrastructures
• Ideally has some programming knowledge, preferably Python, Node.js, Javascript, or Go
• Ideally has some experience deploying solutions to enterprise clients
