ML Feature Engineer

About Abnormal Security

Users and companies are constantly under attack but Abnormal Security's team and patented, ML-first approach is redefining email security for the next generation. Our incredible team needs your help to keep ahead of the evolving threats facing the world. We tackle critical challenges using novel approaches and modern technologies that help make the world a safer place.

Call us Abnormal, but tackling impossible problems takes partnership with customers. By listening to what they want we can build them what they need to stop adversarial cybercrime. It also means our customers love what we build for them because it solves the problems that matter to them! And, of course, it is beautiful to look at and easy to use and administer!


But it's not just our products; we are Abnormal too.


We've combined some of the best talent in the world with serially successful & passionate leadership, which gives us the ability to tackle complex challenges, build incredible things, and experiment and iterate quickly! Then, we empower our people to take ownership of complex end-to-end problems in a culture that supports and rewards them.

Come see what's so great about being Abnormal!


We're hiring a Feature Engineer who will help us improve the foundations of our core "detection engine."

In this role you will:

  • Build new (and improve existing) productionized features and rules at the core of our ability to detect potential threats
  • Perform data driven analysis of historical data to suggest and validate features & rules (and track their impact on efficacy)
  • Debug & remediate problems with our detection efficacy (reduction of FNs/FPs)
  • Help create sustainable systems and methods to improve detection efficacy in an ever-evolving threat landscape

Team & Work Summary:

Our Detection Engineering team powers the core functionality our customers rely on to identify and stop the complex and adversarial, often socially-engineered, email-based attacks ravaging their businesses.

It is home to ~40 world-class engineers with broad experiences spanning across household name "big tech" companies, bleeding edge security companies, AdTech teams, Trust & Safety orgs, and everywhere in between. Who, working collaboratively and iteratively, have created a completely novel & disruptive "ML-first" product that continues to exceed what customers even thought was possible from their "email security" provider.

The Feature Engineer on this team will primarily be responsible for improving the detection product by designing high impact features and rules and features to catch more attacks.

This is NOT a Research, Data Science, Threat Intel, or other "theory-driven" team. You'll build systems to solve real problems for real customers.


To qualify, you'll need:

  • 1+ year of experience building complex ML-related systems in production
  • To be conversant with Python
  • Experience with PySpark or Spark
  • Strong software fundamentals - Ability to write high-quality, well-tested code
  • The ability to understand existing systems and quickly build & iterate on top of them
  • To work with other stakeholders to identify and build tools & processes to increase overall process efficiency

Why Abnormal?

We're on a serious mission to "protect the internet" and we're adamant that building a great team will help us build a great product AND a great company! In addition to ensuring our compensation packages and benefits remain compelling to the caliber of talent we hire - we also seek to provide both clear career and personal growth opportunities. We've built a diverse and inclusive team that values the contributions and voice of all team members. Let's chat about our team and opportunities - we'd love to show you just how GREAT being "Abnormal" can be!
