About Kasada

Join us in stopping bad bots, for good! Kasada protects millions of online users everyday. Founded to stop automated bot attacks, we believe the internet should be a safe place for everyone. Bad bots are highly destructive. They take over accounts, steal content, overload systems and infrastructure and cause billions of dollars in damages every year. Seeking to restore trust in the internet, Kasada stops bots at the very first request including those that have never been seen before.

We’ve grown from a few friends working out of a shipping container under the Sydney Harbour Bridge to now operating globally, we’re spread across the world protecting some of the most well-known brands on the face of the earth.

We’re an innately curious team that’s not afraid to bring bold ideas to create better ways of solving problems. We’re looking for people who are passionate about solving some of the most difficult and pressing cybersecurity issues, while having fun doing it!

You will be the founding member of the Data Science team that we’re bootstrapping. You will work closely with one of our Product Managers who has a background in cybersecurity and a PhD in adversarial ML. You get to learn the domain from our many experienced security analysts, researchers and engineers working on both the detection and data systems side. This is a startup environment, so having high agency and a bias towards an iterative approach will help you thrive. This is not another GenAI thing!

In terms of existing tech stack: it is all AWS. Our data environment is Kafka, Fink, S3, Athena, Clickhouse. Most production applications, including detection systems are written in NodeJS. Notebooks are written in Jupyter with SageMaker tooling.

Collaborate closely with engineers, researchers, and product managers to operationalise models and integrate them into Kasada’s platform

Design experiments to rigorously evaluate detection effectiveness and resilience against attacker adaptation

Stay on the cutting edge of adversarial ML and cybersecurity, translating research into practical defence capabilities

Communicate insights and outcomes clearly, ensuring technical and business stakeholders can act on findings

What You’ll Bring

4–6+ years in data science with exposure to a variety of problem domains

Production experience with unlabelled data, unsupervised learning or anomaly detection

You are strong in sampling, inference, uncertainty quantification and are comfortable with high volume time series data

Fluency with Python, ML libraries and SQL

Strong experience with transforming data in AWS environments and productionizing notebooks/pipelines

Excellent problem-solving and analytical skills, with attention to detail.

Strong communication and collaboration skills — able to influence, teach, and align diverse stakeholders
