Senior Staff Software Engineer - AI/ML Inference Engineering

Company DescriptionIt all started when engineer Fred Luddy wrote code that automated a tedious task for his coworker, Phyllis. She cried tears of joy. That moment inspired Fred to build a company that could do that for everyone—freeing people from busywork so they could focus on meaningful work. Today, ServiceNow is the AI control tower for business reinvention. Our ServiceNow AI platform brings together any AI, any data, and any workflow— helping 85% of the Fortune 500 work smarter, faster, and better.

You will own the end-to-end inference lifecycle—from onboarding cutting-edge models to deploying optimized inference engines in production across multiple backends on Kubernetes infrastructure. You'll also architect the intelligent gateway layer using Envoy and ext_proc to enforce access control, provide observability, and enable advanced request routing. This role combines deep technical expertise in GPU compute, LLM APIs, inference frameworks, containerization, orchestration, and API gateway architecture with a bias toward pragmatic engineering and measurable performance impact. QualificationsTo be successful in this role you have:Expertise in Go or Python, OOP, Design Patterns, time and space-efficient algorithmsModel-serving and runtime experience, such as vLLM, TensorRT-LLM, Triton Inference Server.Exposure to LLM APIs or ML-serving systems, or a clear ability to ramp up quicklyExperience building new products that use challenging algorithmsExpertise in coding efficient, object-oriented, modularized and quality softwareKnowledge of core AI/ML techniques and algorithmsKnowledge of unit testing, profiling, and code tuningAI skills Artificial intelligence strategy is a critical skill at Experienced proficiency for IC5 — it applies to how you build and to what you build. Confident use of AI coding assistants such as GitHub Copilot or Cursor, paired with the critical eye to review AI-generated code as rigorously as any other — catching logic errors, security anti-patterns, and missed edge cases rather than treating model output as production-ready. AI-assisted debugging and trace analysis, and a clear understanding of the data privacy rules governing what goes into a prompt.Mandatory minimum 8+ years of Backend software engineering experience 4+ years of designing and operating distributed systems Bachelor’s degree in computer science, software engineering, or a closely related technical field required.A master’s degree may offset up to one year of the experience minimum. Equivalent practical experience is considered where technical depth is clearly demonstrable.Desired skills:Deploy, scale, and operate services in production Kubernetes environments, including Helm-based deployments and CI/CD pipelines that make releases repeatable and safe to roll back. Own observability for what you build — meaningful metrics, useful logs, real tracing, and alerts that fire on customer impact rather than on noise. Debug and resolve production incidents independently, participate in on-call, run root-cause analysis, and operate against defined service level objectives.
