Software Engineer III– AI Systems

Position Summary...We’re seeking a Software Engineer to design and build AI-first systems with a focus on agentic AI, high performance data/compute frameworks, and scalable, production-grade services. You’ll work across model-driven features and platform layers—integrating LLMs/agents, orchestrating pipelines with Ray, accelerating data science workloads with RAPIDS, and delivering robust APIs and services that power high-impact AI applications at scale.
The ideal candidate blends strong software engineering fundamentals with practical ML systems exposure and a passion for performance, reliability, and developer experience.

What you'll do...Key Responsibilities  AI Systems & Agentic Workflows 

• Build agentic AI services (planning, tool use, retrieval, feedback loops) and integrate them with internal systems and APIs. 

• Implement orchestration, memory, tooling, evaluation, and guardrails for agentic workflows. 

• Collaborate with DS/MLE partners to productionize models (LLMs, GNNs, embedding services) behind stable APIs and SDKs. 

Accelerated Compute & Data Pipelines 

• Develop GPU‑accelerated pipelines using RAPIDS (cuDF/cuML/cuGraph) and optimize end‑to‑end performance. 

• Use Ray (or similar) for distributed compute, batch/stream processing, and scalable workflow orchestration. 

• Profile and optimize bottlenecks across CPU/GPU, memory, and I/O layers; implement caching, vectorization, and async patterns. 

Service & Platform Engineering 

• Design and maintain reliable microservices for training/inference, vector indexing, and real-time decisioning. 

• Implement observability (tracing/metrics/logging), fault tolerance, auto-scaling, and cost-aware execution. 

• Create internal SDKs/CLIs to streamline developer workflows, testing, and reproducibility. 

Quality, Security & MLOps Integration 

• Establish CI/CD for AI services (unit/integration/e2e tests, canaries, blue/green, rollback). 

• Integrate with feature stores, vector databases, artifact registries, and model catalogs. 

• Enforce security, privacy, and compliance (data minimization, PII handling, governance, auditability). 

Collaboration & Influence 

• Partner with product, platform, and DS/MLE teams to align requirements, SLAs, and success metrics. 

• Document systems thoroughly; contribute to design reviews and engineering best practices. 

• Mentor peers on AI systems patterns, distributed compute, and performance engineering. 

Minimum Qualifications 

• Bachelor’s/Master’s in CS, Engineering, or equivalent industry experience. 

• 4+ years building production backend or platform services (preferably in AI/ML contexts). 

• Proficiency in:  

• Languages: Python (primary), plus one of Go/Java/C++ for performance services. 

• Distributed frameworks: Ray, Spark, or Dask. 

• Accelerated compute: RAPIDS (cuDF/cuML/cuGraph) and GPU-aware programming concepts (streams, memory). 

• Service frameworks: FastAPI/Flask (Python), K8s (Kubernetes) and containerization (Docker). 

• Strong foundations in data structures/algorithms, concurrency, networking, and systems design. 

Preferred Qualifications 

• Production experience with agent frameworks (e.g., LangGraph-style planners, tool-use patterns, retrieval and memory components). 

• Experience with vector databases (e.g., FAISS, Milvus, pgvector, Pinecone) and feature stores. 

• Familiarity with LLM and embedding services, prompt/tooling patterns, and evaluation harnesses. 

• Hands-on with Kubernetes, autoscaling (HPA/KEDA), and GPU scheduling/operators. 

• Performance profiling: PyTorch profiler, Nsight, line-profiler, Ray dashboard. 

• Experience with vLLM, Triton Inference Server, ONNX Runtime, or TensorRT for high‑throughput inference. 

Soft Skills & Leadership 

• Pragmatic problem solver with a bias for measurable outcomes (latency, throughput, reliability). 

• Excellent communicator able to translate between research goals and production constraints. 

• Drives clarity in ambiguous problem spaces; mentors others and uplifts engineering standards.
