Staff / Senior Staff Engineer, AI Products

Role Description

We’re looking for a Staff or Senior Staff engineer to help build the next generation of security products at Aegis. This is a highly technical role with a path to significant leadership. You won’t walk in and inherit an organization because of your title. You’ll start by owning hard problems, shipping, setting technical direction, and making the engineers around you better. As you prove that you can lead the product and the people building it, the scope can grow quickly.

If you’re a Staff or Senior Staff engineer who wants to build a team—or an engineering manager who wants to get closer to the technology before taking on much larger leadership scope—this role is designed for that trajectory.

Your Mission:

• Build security systems that can make good decisions from incomplete and noisy information.
• Work on problems like:
  • Turning large volumes of noisy security data into high-confidence detections.
  • Influencing/Participating in model creation to build the best product.
  • Understanding what “normal” looks like when it is different for every user and organization.
  • Moving new detection ideas from prototype to reliable production systems.
  • Measuring whether the systems we build are actually correct.

The systems you build will operate in environments where false positives have consequences and latency, precision, reliability, and customer trust all matter. You’ll work across detection systems, distributed infrastructure, product surfaces, and AI inference—and you’ll be expected to understand the full path from raw data to a customer-visible decision.

Qualifications

• Have operated at Staff-level technical scope, or have equivalent experience leading technically complex systems and teams.
• Have built production systems where false positives, correctness, reliability, or risk mattered.
• Can move between architecture and implementation without treating either as someone else’s job.
• Are comfortable making decisions with incomplete information and updating them quickly as you learn.
• Can prioritize across multiple important problems instead of treating every request as equally urgent.
• Communicate technical decisions clearly in writing.
• Make other engineers more effective, whether or not you have formally managed them.
• Want significantly more responsibility than your current environment can give you.
• Most importantly, you are excited by the problems themselves.

Requirements

• Experience in one or more of:
  • Security detection, fraud, abuse, or other adversarial systems.
  • Behavioral or anomaly detection.
  • Data-intensive distributed systems.
  • LLMs used in production decision-making.
  • Building evaluation systems and labeled datasets for ML or AI products.
  • Enterprise security products or integrations.
  • Taking an early product from a small number of users to broad production adoption.
  • Building or leading engineering teams in an early-stage company.

Benefits

• You’ll work on problems at the intersection of AI and security.
• You’ll build systems that make real decisions.
• You’ll have unusual ownership.
• You’ll work with people who have built defensive systems at massive scale.
• You’ll move quickly.

Company Description

We’re small, technical, and ambitious. You’ll have a lot of autonomy and a corresponding amount of responsibility. We care about measurable outcomes more than ceremony, clear thinking more than hierarchy, and people who can learn quickly more than people who already know every answer.

We expect senior engineers to write code, write down their decisions, talk to customers, challenge assumptions, and leave both the system and the team better than they found them.

If your current role feels too narrow, too slow, or too far removed from the problems that matter—and you want to see how much scope you can earn in a fast-growing AI-native security company—we should talk.
