We’re looking for a motivated, highly talented engineer to join our AI Platform team. You’ll work with world-class engineers to design and enhance the AI models that power our security products. Learn how to build and scale the underlying system that hosts these models.

If you love solving hard problems, experimenting with the NLP model architectures, latest LLMs, eager to dive deep into the internals of the underlying systems, and ultimately make a real impact — this is your chance to jump in early and grow fast.

What You’ll Do

Build and ship the AI systems that power Nightfall’s Security products.

Work hands-on with Python to analyze data, experiment with new natural language or other model architectures, fine tune models, benchmark and monitor model accuracy, build automation for automated training and deployment, real-time inferencing, or designing agentic workflows.

Work hands-on with Go to build the microservices that ingest and process data at scale through the use of streaming infrastructure, distributed caching, and highly concurrent execution.

Collaborate across engineering and product to turn ideas into live AI features

Participate in the team's oncall rotation to help drive operational excellence

You’re a Great Fit If You:
