Senior AI Full Stack Engineer

About the role

We are looking for a Senior AI Full Stack Engineer to design, build, and ship production-grade AI-powered applications at the intersection of modern web engineering and generative AI/agentic systems. As an AI-native engineer, you will instinctively use LLM APIs, RAG pipelines, multi-agent orchestration, and vector databases as core building blocks while owning the complete product surface—from a performant React/Next.js front end through a scalable FastAPI or Node.js back end to cloud-deployed, observable production systems.

You will collaborate with AI Architects, data scientists, product managers, and UX designers to deliver AI-driven features for connected vehicle platforms, in-vehicle infotainment (IVI), manufacturing intelligence, and internal enterprise tools at scale.

Responsibilities

• Design and build end-to-end AI-powered product features, owning the full stack from React/Next.js UI through FastAPI/Node.js backend services to cloud infrastructure and LLM integrations.
• Architect and implement LLM integration layers, connecting to OpenAI, Anthropic Claude, Google Gemini, Meta Llama, or other foundation models via APIs, fine-tuned endpoints, or on-device inference.
• Build production-grade RAG (Retrieval-Augmented Generation) pipelines, including document ingestion, chunking strategies, embedding generation, vector store management, and orchestrated retrieval for accurate, low-hallucination AI responses.
• Develop multi-agent and agentic workflow systems using frameworks such as LangChain, LangGraph, CrewAI, or AutoGen, designing agent memory, tool use, planning loops, and goal decomposition.
• Engineer prompt engineering strategies, guardrails, and context management systems to optimize LLM output for latency, cost, and quality at scale.
• Build and maintain scalable microservices and event-driven backend architectures (Kafka, Redis, async queues) to handle high-throughput AI workloads and long-running agent tasks.
• Design responsive, performant front-end experiences that elegantly surface AI capabilities, including real-time streaming responses (WebSocket/SSE), conversational UIs, AI-assisted dashboards, and multi-modal interfaces.
• Establish observability and monitoring frameworks for AI production systems, including model performance tracking, hallucination detection, token cost monitoring, latency profiling, and bias alerting.
• Implement responsible AI controls at the application layer, such as input/output guardrails, content filtering, PII redaction, rate limiting, and audit logging for regulatory compliance.
• Integrate AI features into automotive-domain applications, including connected vehicle dashboards, IVI systems, manufacturing quality intelligence platforms, and supply chain optimization tools.
• Collaborate with AI Architects to translate architecture blueprints into production code and provide engineering feedback to improve architectural decisions.
• Champion engineering excellence through code reviews, automated testing (unit, integration, AI evaluation), CI/CD pipelines, and documentation for AI-enabled features.

Requirements

• Bachelor’s degree in Computer Science, Software Engineering, or a related technical field; Master’s degree a plus.
• 7+ years of professional full stack engineering experience, with at least 2+ years building and shipping production AI/LLM-integrated features.
• Proven track record delivering AI-powered products to real users at scale (prototypes do not count).
• Expert-level proficiency in React and Next.js (App Router, SSR, SSG, streaming); TypeScript required.
• Experience building real-time AI interfaces, including streaming LLM responses via WebSocket or Server-Sent Events (SSE), conversational chat UIs, and multi-modal content displays.
• Strong command of modern CSS, state management (Zustand, Redux Toolkit, or Jotai), and UI component libraries.
• Strong Python backend development using FastAPI (preferred) or equivalent; experience building async, high-throughput REST and streaming APIs.
• Solid understanding of microservices design patterns, including event-driven architecture, message queues (Kafka, Redis Pub/Sub, Celery/Taskiq), and fault-tolerant distributed systems.
• Database proficiency: PostgreSQL, MongoDB, and Redis for caching and session management.
• Hands-on production experience integrating LLM APIs: OpenAI GPT-4o, Anthropic Claude, Google Gemini, Meta Llama, or Mistral.
• Deep expertise in RAG architecture: document processing, embedding models, chunking strategies, semantic search, and vector databases (Pinecone, Weaviate, Chroma, pgvector, Qdrant).
• Experience with agentic AI frameworks: LangChain, LangGraph, LlamaIndex, CrewAI, AutoGen, or OpenAI Agents SDK.
• Strong prompt engineering and context engineering skills; experience designing multi-turn conversations, tool-calling workflows, and structured LLM output parsing.
• Experience implementing LLM guardrails, hallucination mitigation, and output validation for production systems.
• Strong experience with at least one major cloud platform: AWS, Azure, or GCP; familiarity with managed AI/ML services (AWS Bedrock, Azure OpenAI Service, Vertex AI).
• Containerization and orchestration: Docker and Kubernetes; experience with Helm charts and cloud-native deployments.
• CI/CD pipelines for AI-enabled products: automated testing, model evaluation gates, and zero-downtime deployments.
• AI observability tooling: LangSmith, Weights & Biases, Helicone, or Arize for LLM tracing, cost tracking, and quality monitoring.
• General observability: OpenTelemetry, Prometheus, Grafana, or Datadog for distributed tracing, metrics, and alerting.

Benefits

• Great medical and dental benefits.
• Company-matched 401K retirement savings.
• Annual bonus program.
• Educational assistance.
• Relaxed dress code.
• PASATalks speaker summits.
• Leadership and mentorship programs.
• High5 reward recognition program.
• Onsite happy hours.
• Additional benefits and perks found within the ‘Our Culture’ section.
