Job Description
At Datadog were building an AI Platform that powers ML and LLM features across our observability and security products. The Serving team plays a mission-critical role in this platform: ensuring that trained models can be reliably deployed and served at scale in production across multiple data centers and compute environments.
Our goal is to enable self-serve performant and observable model inference workflows. This includes building Ray-based serving infrastructure deploying inference endpoints on both CPU and GPU supporting rollback strategies and enabling shadow traffic A/B testing and continuous improvement of deployed models.
Were looking for a Senior Software Engineer to lead the design and development of our high-scale model serving systems. This role will work across infrastructure observability and ML engineering domains to deliver production-ready inference capabilities used by applied scientists and product teams across Datadog.
At Datadog we place value in our office culture - the relationships that it builds the creativity it brings to the table and the collaboration of being together. We operate as a hybrid workplace to ensure our employees can create a work-life harmony that best fits them.
What Youll Do:
- Architect and build systems for serving ML and LLM models across all data centers with strong SLAs observability and reliability.
- Design and optimize Ray-based inference infrastructure to handle both low- and high-throughput workloads.
- Enable applied scientists to deploy and test models via self-service tools CI/CD pipelines and rollback mechanisms.
- Implement A/B testing and shadow deployment capabilities to evaluate new model versions in production.
- Collaborate with platform teams to improve GPU provisioning traffic routing and runtime performance.
- Instrument inference workflows with rich telemetry (latency token counts errors) to drive performance and safety analysis.
Who You Are:
- You have 6 years of backend or infrastructure engineering experience including 2 years working on ML/AI platforms.
- You have experience building distributed systems ideally in model serving realtime inference or large-scale APIs.
- You are proficient in Python Go or another systems language and understand performance tuning in high-throughput environments.
- You are familiar with Ray or other inference-serving frameworks (e.g. TorchServe Triton BentoML).
- Youve worked with GPUs and understand how to build infrastructure that supports heterogeneous compute workloads.
- Bonus points: experience with AI observability rollback strategies or in-house deployment proxies.
Datadog values people from all walks of life. We understand not everyone will meet all the above qualifications on day one. Thats okay. If youre passionate about technology and want to grow your skills we encourage you to apply.
Benefits and Growth:
- New hire stock equity (RSUs) and employee stock purchase plan (ESPP)
