We build self-serve infrastructure that empowers them to bring new models into production, adopt open source software and models, and expand what they can accomplish with machine learning at scale.\nWe work at the intersection of a rapidly evolving open source ecosystem and demanding production workloads. With active customer demand and growing modeling ambitions, we’re advancing the infrastructure behind today’s predictions while building the capabilities that enable the next generation of ML innovation.\nAbout the Role\nYou’ll help build the next generation of our ML serving platform, connecting request routing and online feature retrieval with model inference on CPU and GPU infrastructure. You’ll tackle challenging infrastructure problems involving latency, reliability, resource efficiency, and scale, and make those capabilities accessible through self-serve tools and workflows.\nWorking alongside experienced platform engineers, you’ll own defined projects from technical design and implementation through testing, rollout, and production support. You’ll partner directly with internal teams to understand emerging modeling requirements, remove adoption barriers, and turn advances in open source technology into measurable production improvements.\nYou’re excited about this opportunity because you will…\nEmpower modelers through self-serve infrastructure. Build tools, APIs, and workflows that help internal teams deploy, configure, validate, and operate models independently, accelerating ML adoption across business verticals.\nBring open source innovation into production. Evaluate and integrate evolving inference frameworks and enable open source models, translating promising capabilities into reliable, efficient services at scale.\nSolve demanding inference infrastructure problems. Improve the systems that route prediction requests, retrieve online features, and execute models on a platform serving tens of millions of predictions per second.\nHelp evolve our disaggregated serving architecture. Build modular components that allow routing, feature retrieval, and model execution to evolve and scale independently as workloads and modeling requirements change.\nImprove Kubernetes deployment and autoscaling. Help workloads respond to changing traffic while meeting latency and availability requirements and using CPU and GPU resources efficiently.\nMake adoption and rollout easier. Build integrations, validation, and migration tooling that help teams adopt new serving capabilities and our unified global platform with confidence.\nOwn performance and reliability in production. Use benchmarking, profiling, metrics, and tracing to identify bottlenecks; participate in on-call and improve automation and runbooks to make the platform easier to operate.\nWe’re excited about you because…\nYou have 2+ years of software engineering experience building and maintaining production services or infrastructure.\nYou have strong computer science fundamentals and proficiency in a backend or systems programming language such as Java, Kotlin, Go, C++, or Python.\nYou understand distributed systems fundamentals, including concurrency, networking, timeouts, failure handling, and performance trade-offs.\nYou enjoy challenging infrastructure problems and can independently turn a defined problem into a technical design, tested implementation, and safe production rollout.\nYou have experience debugging production systems and using operational data to improve reliability, performance, or cost.\nYou care about the engineers using your platform and collaborate effectively with customers and partners to make complex infrastructure easier to adopt.\nYou hold a degree in Computer Science or a related field, or have equivalent practical experience.\nNice to Have\nExperience with ML inference infrastructure, online feature retrieval, or other latency-sensitive distributed services.\nExperience operating containerized workloads on Kubernetes, including deployment, resource management, or autoscaling.\nExperience building self-serve developer platforms, APIs, or automation that helps other engineers move faster.\nExperience integrating open source infrastructure or models and validating their behavior under production workloads.\nFamiliarity with CPU/GPU performance profiling, inference runtimes, or model deployment workflows.\nRelevant Technologies and Keywords\nOpen source inference runtimes and models, NVIDIA Triton, ONNX Runtime, Kubernetes, CPU/GPU inference, gRPC, online feature stores, distributed systems, performance profiling, autoscaling, and self-serve ML infrastructure.\nFamiliarity with every technology is not expected. We welcome engineers with strong backend and infrastructure fundamentals who are excited to learn the ML serving ecosystem.\nCompensation\nThe successful candidate’s starting pay will fall within the pay range listed below and is determined based on job-related factors including, but not limited to, skills, experience, qualifications, work location, and market conditions. Base salary is localized according to an employee’s work location. Ranges are market-dependent and may be modified in the future.\nIn addition to base salary, the compensation for this role includes opportunities for equity grants.
