Design and build rendering infrastructure to run GPU-accelerated, physically-based sensor simulation at cluster scale. Integrate the renderer with AV stacks and ML training, ensure deterministic execution and timing fidelity, optimize GPU memory and throughput, implement multi-world execution and asset delivery, reduce cold-starts, and maintain profiling, testing, and cross-team collaboration.

Lead architecture and implementation of AI-security products, define technical direction, drive cross-team initiatives, design secure scalable backend systems, and address systemic risks while remaining hands-on in coding, prototyping, and debugging.

As a Staff Software Engineer on the Inference team, you'll lead architecture and optimization for Kubernetes-native AI workloads, enhancing performance and reliability across services.

Develop and execute software test plans, cases, and suites across complex systems. Build automated testing frameworks, validate APIs and integrations, integrate tests into CI/CD pipelines, isolate defects, perform root cause analysis, document findings, and collaborate with software engineers on corrective actions and quality improvements.

Design and build large-scale, highly available Responsible AI cloud services. Lead architecture, development, release, and production readiness. Collaborate with engineers, scientists, and product managers to integrate Responsible AI features across Azure AI and related services, drive DevOps practices, and improve performance, observability, and reliability.

Design, develop, and maintain scalable Java backend software, APIs, and automation for an enterprise cloud platform. Collaborate with architects, product managers, and engineers to define requirements, improve performance, resolve technical challenges, and deliver high-quality solutions. Apply modern engineering and AI-enabled development practices, participate in design and code reviews, understand end-to-end systems, mentor junior engineers, and contribute to technical innovation.

The Functional Safety Software Engineer will develop technical safety requirements, lead software safety specification, and perform analyses to comply with ISO 26262, focusing on autonomous vehicles.

Build and maintain an agentic platform that transforms high-stakes medical and legal casework into structured context. Work across the full stack: agent architectures, eval frameworks, data ingestion/indexing, and user-facing tooling. Ship workflows, design reliability-focused evals and guardrails, iterate with user feedback, and set patterns for AI-native development in a healthcare context.
