Sterling's Strategic Technologies Group is responsible for learning and becoming subject matter experts in new and emerging technologies. Our team uses this expertise to broaden the portfolio of products and solutions that the company sells, delivers, and manages. Our engineers work on a range of AI-integrated systems, from production RAG platforms and LLM orchestration layers to digital human solutions and intelligent automation pipelines. We are looking for a Backend ML Engineer who is interested in taking AI/ML systems from prototype to production, designing inference APIs, building retrieval and orchestration pipelines, integrating large language models, and operating ML infrastructure at scale. If you thrive in a collaborative, client-focused environment and enjoy shipping AI features that real users depend on, we'd love to have you on our team., * Build, test, and maintain production ML services - inference APIs, retrieval pipelines, orchestration layers, and guardrail/evaluation components. * Design scalable RESTful and streaming APIs that serve ML model outputs reliably under real-world load. * Integrate and tune LLMs, embedding models, and rerankers; evaluate trade-offs across hosted (Anthropic, OpenAI, Vertex) and self-hosted (HF, vLLM) options on cost, latency, and quality. * Build ingestion and chunking pipelines for unstructured data (PDFs, HTML, transcripts) and maintain vector store schemas for multi-tenant or multi-domain retrieval. * Implement evaluation harnesses to measure retrieval quality, generation faithfulness, and end-to-end answer correctness; close the loop from evals back into pipeline improvements. * Containerize and deploy ML workloads with Docker and Kubernetes; manage GPU/CPU resource allocation and model versioning. * Optimize database queries, vector search performance, and caching strategies (including LLM prompt caching) to reduce latency and cost. * Implement CI/CD pipelines for ML services and instrument monitoring for both system metrics (latency, error rate) and ML-specific metrics (retrieval quality, hallucination rate, drift) * Collaborate with frontend engineers, ML researchers, and product analysts to translate model capabilities into shipped features. * Document backend and ML infrastructure, including model cards, evaluation results, and architectural decisions * Travel - must be willing to travel 25% and periodically up to 50%. ## Related Videos - [The Resilience of the World Wide Web](https://www.wearedevelopers.com/videos/1281-the-resilience-of-the-world-wide-web) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Photonic Computing: Programming a New Class of AI Accelerators (incl.
