Node.JS Backend Engineer

Node.js Engineering at Tessian

Our Node.js team are building a scalable infrastructure for processing email traffic in real-time. You'll be a software engineer with a strong interest in developing backend services in Node.js, looking to start a fresh challenge in 2019. Our stack includes core Node.js, Docker, AWS/Azure, and Postgres, amongst others and you'll be helping to build a new generation of dependable AI-based enterprise security.

Unlike most Node.js roles we're using this technology to execute some pretty low-level concepts and we're drilling down to fundamentals. This isn't an Express app or a full-stack web role; we're building a core, high-performance backend to support Tessian's cybersecurity platform. You'll make a big impact in a small team, with opportunities to drive our future technology, mentor other developers and solve business-critical issues.

You'll be a great thinker and have the ability to plan, question, suggest and explain - skills we value as highly as your ability to write solid, dependable code. As part of our team, you'll be collaborating with our Data Scientists who are building new machine learning threat models, architecting our application to scale with our growing client base, diagnosing critical issues and contributing to planning and architecture discussions.

We believe in regular and continuous development and seek to create opportunities for all team members. We have regular cross-discipline tech talks and we encourage multi-disciplinary development. Dealing with massive datasets at scale requires ingenuity and strong analytical skills, and we build quickly, following both agile and continuous delivery paradigms. You'll have a degree of autonomy to work on your various projects, and be a part of our regular round tables to bounce ideas around. We believe in continuous career development and will look to create opportunities for you to evolve both personally and professionally.
