Full Job Posting

Key Responsibilities

  • AI/ML Engineering & Delivery
  • Design, build, and deploy production AI systems including RAG pipelines, agentic workflows, multi-model orchestration, and intelligent automation
  • Integrate large language model (LLM) APIs and AI/ML services into enterprise applications (GCP Vertex AI)
  • Implement and optimize prompt engineering strategies, fine-tuning pipelines, embeddings, and vector search solutions
  • Build and maintain AI orchestration workflows using frameworks such as LangChain, Semantic Kernel, AutoGen, CrewAI, or LlamaIndex
  • Develop custom AI agents, tools, and autonomous workflows that solve real business problems
  • Establish evaluation frameworks for AI systems — measuring accuracy, latency, cost, hallucination rates, and business outcomes
  • Full Stack Development & Integration
  • Build end-to-end AI-powered applications spanning frontend, backend, APIs, and data layers
  • Develop robust backend services using Python (FastAPI/Django) or Node.js to support AI workloads
  • Implement and optimize RESTful APIs, GraphQL endpoints, and event-driven integrations for AI services
  • Build modern frontend interfaces for AI-powered features using React, Angular, or Vue.js with TypeScript
  • Write clean, well-tested, production-ready code with a focus on maintainability and operational excellence
  • MLOps & AI Infrastructure
  • Design and implement MLOps/LLMOps pipelines for reliable model deployment, versioning, and lifecycle management
  • Configure and manage cloud-native AI infrastructure (AWS, GCP) including model serving, orchestration, and auto-scaling
  • Implement observability for AI systems — monitoring model drift, token costs, latency, throughput, and quality metrics
  • Build and maintain CI/CD pipelines for AI model deployment, automated testing, and continuous evaluation
  • Design for resilience: failover strategies, fallback models, circuit breakers, and graceful degradation
  • AI-Augmented Development
  • Leverage AI coding assistants (GitHub Copilot, Cursor, Claude, etc.) to dramatically accelerate development workflows
  • Use AI tools for code generation, refactoring, test writing, documentation, and code review
  • Develop and maintain custom AI-powered developer tools, automations, and internal platforms
  • Establish guardrails, security practices, and governance for responsible AI usage in engineering
  • Technical Documentation & Mentorship
  • Influence engineering culture by evangelizing AI-first development practices across teams
  • Train and upskill team members on effective use of AI tools, LLM integration patterns, and ML best practices
  • Contribute to internal knowledge bases, tech talks, and communities of practice
  • Partner with product, design, and data science teams to identify and deliver AI-driven opportunities
  • Participate in architecture reviews and design discussions, ensuring AI solutions are production-ready from day one

Required Qualifications

  • Experience: 8+ years of professional software engineering experience, with 2+ years focused on AI/ML solution development and delivery
  • Education: Bachelor's degree in Computer Science, Software Engineering, AI/ML, or related field (or equivalent experience)
  • AI/ML Expertise:
  • Strong understanding of large language model architectures, capabilities, and limitations
  • Proven track record building and deploying production AI systems (RAG, agents, fine-tuning, embeddings, vector search)
  • Proficiency with AI orchestration frameworks (LangChain, Semantic Kernel, AutoGen, CrewAI, LlamaIndex)
  • Hands-on experience with major LLM providers and platforms (OpenAI, Anthropic, Google Vertex AI, AWS Bedrock)
  • Solid understanding of prompt engineering, evaluation methodologies, and AI safety/guardrails
  • Programming: Expert-level proficiency in Python; strong skills in at least one additional language (Java, TypeScript/Node.js, C#/.NET)
  • Cloud & Infrastructure: Hands-on experience deploying and operating AI workloads on cloud platforms (AWS, GCP, or Azure), containerization (Docker, Kubernetes), and CI/CD tooling (Jenkins, GitHub Actions)
  • Data: Proficiency with SQL and NoSQL databases, vector databases (Pinecone, Weaviate, pgvector, ChromaDB), and data pipeline tools
  • API Development: Proven track record building production APIs (REST, GraphQL, gRPC) and event-driven integrations
  • AI Tools Proficiency: Advanced daily usage of AI coding assistants with demonstrated impact on productivity and code quality
  • Testing: Strong testing practices for AI systems including model evaluation, integration testing, and automated quality checks
  • Communication: Excellent written and verbal communication skills with ability to explain complex AI concepts to diverse audiences
  • -
  • 8+ years of professional software engineering experience, with 2+ years focused on AI/ML solution development and delivery

Preferred Qualifications

  • Experience building enterprise AI platforms serving multiple product teams
  • Familiarity with custom model training, fine-tuning (LoRA, QLoRA), and RLHF techniques
  • Experience with agent-based AI architectures and autonomous multi-step workflows
  • Knowledge of AI security concerns (prompt injection, data leakage, model poisoning) and mitigation strategies
  • Experience in regulated industries (insurance, finance, healthcare) with security and compliance requirements
  • Contributions to open-source AI/ML projects or published technical content
  • Cloud certifications (AWS Solutions Architect, GCP Professional Cloud Architect, or equivalent)
  • Experience with real-time inference, streaming responses, and low-latency AI serving architectures
