Artemis is building the future of AI-driven defense - helping companies detect and defend themselves effectively in an era where AI is fighting AI on the cyber battlefield.

We're backed by First Round Capital, Brightmind, and a group of the cybersecurity industry's most prominent Operators.

Our founders, Shachar (ex-Palo Alto Networks, AWS, Demisto) and Dan (ex-Abnormal Security, Twitter) have previously built, launched, and scaled cybersecurity products loved and trusted by tens of thousands of customers, and have the customer, technology, and security know-hows to deliver this vision.

Our exceptionally strong team includes software engineers, AI researchers, security engineers, and product designers hailing from Google, Abnormal AI, Wiz, Meta, AWS, CERN, SentinelOne, and more.

We are growing our team and looking for passionate builders to join us and support our expanding customer base.

We're looking for a Senior Security Analyst to join Apollo, the managed detection and response service Artemis delivers on top of its platform, as one of its founding analysts. Apollo analysts are the senior security minds our customers count on: the people who determine what a threat really is, what it means for that business, and what happens next. You will be one of the few who establish how that work gets done before the team scales.

The Artemis platform is built to give you the strongest possible starting position. Detections are written for each customer's environment, cases arrive with the investigation done and the evidence assembled, response actions come staged and impact-checked, and the platform already holds a living picture of every user, device, account, and AI agent in the environment. The routine work that fills most analysts' days is handled, which means your day is spent on the work that actually calls for an expert.

You will lead investigations across cloud, identity, endpoint, and SaaS, own the decision on the cases you take, guide customers through what matters and why, and carry incidents from first signal to a clean resolution. Because you work across the full range of environments we protect, you will build fluency in modern attacker tradecraft far faster than a single environment allows. And your reach extends well past the case. You sit with the engineers building the platform, so what you learn in one investigation can ship into the product and go on protecting every customer we defend.

What We Offer

~2 min read

✓Join early enough to shape it. A founding analyst leaves fingerprints on all of it: how the service is designed, the standards the team holds, and what customers receive. The way you work a case becomes the standard the analysts who follow you learn from.

✓Make a real world impact. Every case you work and every call you make protects a real company and the people who depend on it. You are not working theoretical security problems, you are on the front lines of active defense, with customers who rely on the quality of your judgement.

✓Range you cannot get anywhere else. You work across the full set of environments we protect and the full spectrum of attacker behavior we see, so a quarter here builds experience that years inside one environment cannot.

✓Be challenged to be better than ever before. Our team includes some of the smartest and most driven people in the world. We guarantee you will learn more in 1 year here than 10 years in another place.

✓Push the boundaries of technology. The platform handles the detection, investigation, and prioritization that consume most analysts' days, so your time goes to judgement, response, and the customer. You will help define what an AI-native SOC actually looks like.

✓Innovative culture. We obsess about customers, move fast with high quality, and value open communication, mentorship and learning. You will have the autonomy to drive investigations, shape the platform, and own outcomes, not just follow a runbook.
