Job Description / Skills Required

Tessian

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.

Data Engineering at Tessian

As a high-growth scale-up, our email datasets are growing at an exponential rate. This is a great as it allows us to train best-in-class machine learning models to prevent previously unpreventable data breaches, however we're at the scale where our current data pipelines aren't where we want them to be: this is why we’re looking to bring another Data Engineer into the Tessian family.

You will sit in our Data Engineering team and work day-to-day with our Data Scientists to build out infrastructure and pipelines, empowering teams to iterate quickly on terabytes of data. You'll be hugely impactful in this high-leverage role and we strongly believe that if we can query all of our data, in near real-time, and using scalable systems, then we can deliver limitless value to our clients through the data breaches we prevent.
Some interesting projects we’re working on:

Building an Ingestion system to process Insights from different models using Kafka and Spark
Designing the next generation data-lake setting ourselves up to handle massive future scale
Creating a framework allowing us to standardise how we deploy all our ML models to production

We'd love to meet someone who:

Is a highly-skilled developer who understands software engineering best practices (git, CI/CD, testing, reviewing, etc) and infrastructure as code principles.
Has experience working with distributed data systems such as Spark
Has designed and deployed data pipelines and ETL systems for data-at-scale
Has a deep knowledge of the AWS ecosystem and have managed AWS production environments
Has experience with scheduling systems like Airflow
Ideally has been involved in machine learning infrastructure projects from automated training through to deployment
Has an ability to break down ambiguous problems into concrete, manageable components and think through optimal solutions
Enjoys “getting their hands dirty” by digging into complex operations
Takes a high degree of ownership over their workIs a clear communicator with professional presence
Has strong listening skills; open to input from other team members and departments

On a day-to-day basis you'll get to

Build systems to efficiently handle our ever increasing volume of data
Design and implement data pipelines as well as owning the vision of what our systems could achieve in the future
Work with Data Scientists to train, version, test, deploy and monitor our machine learning models in production
Design systems to expose data to our product and engineering teams in a performant way
