Company mission
To give the advantage to those who secure our future.
Role
Who you are
- We’re looking for people who are relentlessly curious and committed to continuous learning
- Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes
- At least 6 years of experience in Python, Node.js, or a comparable language
- Experience with macOS and Windows Endpoint Security
- Proficiency in OS architecture and internals
- Strong customer orientation - you take ownership of customer problems and can diagnose and fix issues on the fly in real-world conditions
- Business and product awareness - genuine interest in the roadmap, the market, and the customers we serve, and the judgment to weigh technical decisions against business impact
- Accountability and growth mindset - you own your outcomes, hold yourself to a high bar, and actively invest in your own and the team's growth
- Excellent problem-solving skills and attention to detail
- Proficiency in browser extension development (Chrome, Firefox, etc.) - Advantage
What the job involves
- As a Staff Endpoint Software Engineer, you'll build the lightweight security components that power our Generative AI Security platform - the core sensors and enforcement mechanisms that operate across endpoints, browsers, and production workloads to deliver real-time, adaptive protection. But building the technology is only half the job
- We're looking for an engineer who understands why we're building it: someone fluent in our product, our roadmap, and the real GenAI risks our customers face every day - and who treats a customer problem as their own until it's solved
- You'll own your work end-to-end, engage directly with the realities of how customers deploy and rely on our sensors, and diagnose and fix issues on the fly when it matters. You'll collaborate with expert engineers on high-impact GenAI security challenges while growing your expertise and your influence on where the product goes next
- Build and optimize sensor components for minimal system footprint - high performance, low resource consumption, and maximum reliability across diverse customer environments
- Evolve our Agentic AI capabilities by helping design adaptive policy logic, improving decision engines, and expanding coverage across platforms - grounded in real customer use cases and roadmap priorities
- Build endpoint and browser security components and integrate them into the platform for real-time GenAI threat detection and data protection (prompt injection, sensitive-data leakage, shadow AI, and more)
- Own customer-facing technical problems end-to-end - investigate production issues, reproduce and fix them quickly under real-world pressure, and follow through until the customer is unblocked
- Translate business and roadmap context into engineering decisions - understand what customers need, where the product is heading, and why, so your technical choices move the business forward
- Collaborate across security engineering, QA, product, and customer-facing teams to hit customer and business goals - not just ship code
- Stay current with GenAI and platform security and fold relevant advances into our sensors, agents, and extensions
Our take
Cybercriminals are now leveraging the power of automation to make the current threat landscape too advanced for a lot of traditional antivirus software. SentinelOne is a cybersecurity company that matches this automation with machine learning-focused software designed to help businesses defend against online attacks.
The company has expanded beyond endpoint security into a broader AI-powered cybersecurity platform spanning endpoint, cloud, identity, and IT operations. This gives SentinelOne access to a larger enterprise market, although it also it also places the company in direct competitions with established cybersecurity leaders, including its biggest rival, CrowdStrike.
As cyberattacks become increasingly automated, the company is expanding its capabilities beyond detection to include AI-driven threat response, helping security teams contain attacks more quickly. While it still trails larger rival CrowdStrike in scale, SentinelOne is investing in platform expansion and automation to compete for enterprises looking to consolidate their cybersecurity into a single solution.
