We design and operate large-scale, resilient systems supporting real-time decision-making and data processing across thousands of services. As we expand our distributed computing and ML infrastructure capabilities, we are building a new team focused on GPU platforms and high-performance model serving technologies. As a Site Reliability Engineer in the GPU team, you will help design, operate, and scale the infrastructure powering machine learning training and inference workloads. You will work on technologies such as: Ray on Kubernetes Build and operate scalable Ray clusters running on Kubernetes. Develop reliable self-service distributed computing platforms for ML workloads. Improve provisioning, observability, reliability, and operational efficiency of ray-as-a-service environments. NVIDIA Triton Inference Server Operate and optimize large-scale inference platforms using Triton. Improve latency, throughput, scalability, and GPU utilization for deep learning inference workloads. You will collaborate closely with ML engineers, data scientists, and infrastructure teams to deliver reliable, production-grade ML platforms accelerating innovation across Criteo. Who You Are: 5+ years of experience in backend engineering, Site Reliability Engineering, or platform engineering roles focused on distributed systems. Strong experience with Kubernetes, including workload scheduling, dynamic provisioning, and custom controllers/operators. Hands-on experience running or optimizing GPU-based workloads in production, ideally for ML training or inference systems. Strong software engineering skills in C#, Python, Go, or similar languages, with a focus on building reliable distributed systems. Experience building or operating production-grade infrastructure with strong requirements around performance, scalability, and reliability. Strong interest in automation, observability, and designing systems that scale efficiently under high load. Bonus Points Experience with distributed ML frameworks such as Ray or similar systems. Familiarity with inference serving stacks such as NVIDIA Triton or TensorRT. Experience with GPU scheduling, resource management, or multi-tenant GPU platforms. Exposure to cloud-native GPU orchestration (GKE, EKS, or on-prem Kubernetes GPU clusters). We acknowledge that many candidates may not meet every single role requirement listed above.

Here's how to pick the right one and stand out in your application.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
