As AI reshapes how organizations build, operate, and innovate, the responsibility to protect them becomes more critical than ever. When you join SentinelOne, your work helps protect global enterprises, critical infrastructure, and the technologies shaping tomorrow. If you are motivated by meaningful challenges and want your impact to be real, measurable, and global, you will find purpose here.\nAbout Us \nSentinelOne is a company at the intersection of AI and security, pioneering a new operating model for cybersecurity. Our AI-native platform unifies protection across endpoint, cloud, identity, data, and AI systems to deliver autonomous detection and response with clarity and speed. By combining real-time analytics, intelligent automation, and a unified data foundation, we reduce noise, simplify complexity, and empower security teams to focus on what truly matters.\nOur teams are builders, problem-solvers, and innovators committed to shaping the future of security. If you are excited to solve hard problems alongside talented, mission-driven people, we invite you to help us build a safer future for humanity.\nWhat Are We Looking For?\nWe’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.\nAs a Staff AI Platform Engineer, Infrastructure Services, you will be tasked with taking ownership of our AI Gateway infrastructure (built on Kong AI Gateway), the system that authenticates, routes, rate-limits, and monitors AI coding assistant traffic org-wide, while also being fluent enough across our broader platform stack to design solutions that span the two. This is a high-autonomy, high-scope role: you will set technical direction for AI infrastructure, drive incident response and reliability work, and partner closely with the engineers who own our CI/CD, GitOps, and artifact systems rather than working in isolation from them.\nWhat Will You Do?\nPrimary responsibilities include:\nWork on the AI Gateway platform: architect, harden, and scale our Kong AI Gateway deployment (Konnect Hybrid on KCP/EKS), including auth (Okta/OIDC), consumer tiers and budgets, rate limiting, semantic caching, and observability.\nLead reliability and incident response: drive root-cause analysis and remediation for gateway issues (timeouts, latency, capacity, failover) and build the monitoring/alerting needed to catch them before users do.\nDesign across the platform, not just the gateway: work fluently with our CI/CD (Jenkins, JPAAS), GitOps and Kubernetes deployment tooling (ArgoCD across dev/gov/prod), artifact management (Artifactory/Xray), GitHub Enterprise administration, and GitHub Actions runner fleet, so that AI infrastructure decisions account for how the rest of the platform actually works.\nEvaluate and roll out AI developer tooling: run structured pilots and adoption efforts for tools like AI-assisted PR review (Qodo) and engineering metrics platforms (LinearB), and make clear build-vs-buy recommendations.\nSet technical direction and mentor: define architecture and standards for AI infrastructure, review designs across the team, and raise the bar for other engineers working in this space.\nPartner cross-functionally: work directly with security, DevEx, and product engineering teams consuming the gateway to translate their needs into platform capabilities.\nHost and serve local models: stand up and operate self-hosted/open-weight model serving infrastructure (e.g. vLLM, NVIDIA Triton/NIM, TGI, Ollama) for workloads where routing to an external provider isn't the right fit, including GPU capacity planning, autoscaling, and cost/performance tuning.\nSupport the broader model lifecycle: help build LLMOps practices such as model versioning, evaluation, and safe rollout, plus supporting infrastructure for retrieval-augmented generation (vector stores, embedding pipelines) as use cases mature.\nTrack usage and cost: build observability into token usage, latency, and spend across both API-based and self-hosted models so the business can see what AI infrastructure actually costs.\nWhat Skills and Knowledge Will You Bring?\nIdeal candidates will have:\n8 or more years of experience in platform, infrastructure, or DevOps engineering, with a track record of owning systems end-to-end in production.\nHands-on experience with API gateway technologies (Kong, Envoy, Apigee, or similar); direct experience with AI/LLM gateway patterns (rate limiting, semantic caching, prompt/response observability) is a strong plus.\nStrong Kubernetes and GitOps experience (ArgoCD or comparable), and comfort operating across multiple environments (dev, gov, prod).\nSolid CI/CD background: Jenkins pipeline design and administration, build infrastructure, and runner/agent fleet management (GitHub Actions runners or equivalent).\nExperience with artifact and package management systems (Artifactory, Xray, or similar) and source control platform administration (GitHub Enterprise).\nWorking knowledge of infrastructure-as-code (Terraform) and cloud platforms (AWS/EKS).\nExperience deploying and operating self-hosted LLM inference stacks (vLLM, NVIDIA Triton/NIM, TGI, Ollama, or similar) and GPU-backed infrastructure, including Kubernetes GPU scheduling and autoscaling.\nFamiliarity with LLMOps practices: model versioning, evaluation harnesses, and usage/cost observability across API-based and self-hosted models.\nTrack record of setting technical direction, driving cross-team initiatives, and mentoring other engineers; this role has significant scope and minimal day-to-day oversight.\nClear, proactive communicator who can explain infrastructure trade-offs to both engineers and non-technical stakeholders.\nExperience operating LLM/AI-assisted developer tooling at scale (Claude Code, Copilot, or similar) inside an enterprise is preferred.\nFamiliarity with Okta/OIDC and enterprise auth patterns for internal platforms is preferred.\nExperience with engineering productivity metrics tooling (LinearB or similar) and AI-based code review tooling (Qodo or similar) is preferred.\nExperience with vector databases and RAG pipelines (e.g. Milvus, Pinecone, pgvector, or similar) in a production setting is preferred.\nExposure to model fine-tuning or lightweight training pipelines (LoRA/QLoRA or similar) for domain-specific model adaptation is preferred.\nWhy SentinelOne?\nAI is redefining how the world operates and rewriting the rules of security in real time, and SentinelOne was built for this moment. From day one, we architected an AI-native platform designed to operate at machine speed, not as an add-on to legacy systems but as the foundation itself. If you want to build where innovation and impact move together, this is that place.\nWe invest in our Sentinels with comprehensive, competitive benefits designed to support you and your family:\nEquity & Rewards\nRestricted Stock Units (RSUs)\nEmployee Stock Purchase Plan (ESPP)\nTime Off & Wellbeing\nFlexible time off\nPaid company holidays and paid sick time\nGender-neutral parental leave\nGrandparent leave\nInsurance & Financial Security\nMedical, dental, and vision coverage\n401(k) retirement plan with company match\nLife and disability insurance\nHealth and dependent care FSA\nVoluntary benefits (hospital, accident, critical illness)\nEmployee Assistance Program (EAP)\nARAG pre-paid legal\nNationwide pet insurance\nCancer Care program\nGlobal business travel medical insurance\nWork Perks & Flexibility\nHome office allowance\nMobile phone reimbursement\nWellness & Lifestyle\nWellness coach\nWellness/gym reimbursement\nFertility coverage\nAdoption & surrogacy reimbursement\nThis U.S. role has a base pay range that will vary based on the location of the candidate. For some locations, a different pay range may apply. If so, this range will be provided to you during the recruiting process. You can also reach out to the recruiter with any questions.\nBase Salary Range\n$156,000—$215,000 USD\nSentinelOne is proud to be an Equal Employment Opportunity and Affirmative Action employer.
