Role
Who you are
- 5 or more years of experience in platform, infrastructure, or DevOps engineering, with a track record of owning systems end-to-end in production
- Hands-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
- Strong Kubernetes and GitOps experience (ArgoCD or comparable), and comfort operating across multiple environments (dev, gov, prod)
- Solid CI/CD background: Jenkins pipeline design and administration, build infrastructure, and runner/agent fleet management (GitHub Actions runners or equivalent)
- Experience with artifact and package management systems (Artifactory, Xray, or similar) and source control platform administration (GitHub Enterprise)
- Working knowledge of infrastructure-as-code (Terraform) and cloud platforms (AWS/EKS)
- Experience 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
- Familiarity with LLMOps practices: model versioning, evaluation harnesses, and usage/cost observability across API-based and self-hosted models
- Track record of setting technical direction, driving cross-team initiatives, and mentoring other engineers; this role has significant scope and minimal day-to-day oversight
- Clear, proactive communicator who can explain infrastructure trade-offs to both engineers and non-technical stakeholders
- Experience operating LLM/AI-assisted developer tooling at scale (Claude Code, Copilot, or similar) inside an enterprise is preferred
- Familiarity with Okta/OIDC and enterprise auth patterns for internal platforms is preferred
- Experience with engineering productivity metrics tooling (LinearB or similar) and AI-based code review tooling (Qodo or similar) is preferred
- Experience with vector databases and RAG pipelines (e.g. Milvus, Pinecone, pgvector, or similar) in a production setting is preferred
- Exposure to model fine-tuning or lightweight training pipelines (LoRA/QLoRA or similar) for domain-specific model adaptation is preferred
What the job involves
- We’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
- As a Senior 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
- Work 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
- Lead 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
- Design 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
- Evaluate 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
- Set 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
- Partner cross-functionally: work directly with security, DevEx, and product engineering teams consuming the gateway to translate their needs into platform capabilities
- Host 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
- Support 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
- Track 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
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.
