The posting, as Artemis wrote it

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

Our platform brings a new approach to the $100B security operations market, building a live model of each customer's environment and using AI agents to detect, investigate, hunt, and respond to threats at machine speed. Just one year after our founding, Artemis is one of the fastest-growing cybersecurity companies of all time, with customers including multiple Fortune 500 companies, Global 2000 enterprises, and AI innovators like Cursor.

We have raised $70M from Felicis, First Round Capital, Theory Ventures, Two Sigma Ventures, Lockstep VC and Brightmind. We are also backed by some of the most prominent operators in cybersecurity, including the CEO of Crowdstrike, the former CEO and CTO of Splunk, and the founders of Abnormal AI and Demisto.

Artemis's founders have built and scaled security products used by tens of thousands of customers. Shachar Hirshberg (CEO) led Amazon GuardDuty, the world's largest cloud detection product, was an early employee at Demisto, the company that invented the SOAR category, was an engineering leader at Palo Alto Networks, and holds an MBA from Harvard. Dan Shiebler (CTO) led all AI and machine learning at Abnormal AI, the pioneer of behavior-based detection, spent five years building analytics using machine learning and vector databases at Twitter, and holds a PhD in machine learning from Oxford.

Our team of software engineers, AI researchers, security engineers, and product designers comes from Google, Meta, AWS, Wiz, CrowdStrike, SentinelOne, Abnormal AI, Perplexity, Bridgewater, Mercor, CERN, and more.

We're growing fast and looking for builders who want to help us serve our rapidly expanding customer base.

Job Overview

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 fi

Compensation

We offer a competitive compensation of $120,000-$160,000 per year, and a top-of-market equity component. A variety of factors are considered when determining the compensation, including a candidate’s professional experience. Final offer amounts may vary from the amounts listed.

Why Work at Artemis?

• 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.
