What you'll be doing:

  • Technical Leadership:
    • Design and implement production-scale AI agent systems and orchestration frameworks (LangGraph, LangChain, similar architectures)
    • Lead architecture for multi-agent systems handling complex business workflows
    • Optimize deployment strategies using both LLMs and SLMs based on use case requirements
    • Build natural language-configurable business process automation frameworks
    • Implement multi-modal AI systems for document understanding (tables, charts, layouts)
  • AI/ML Implementation & Optimization:
    • Deploy and optimize LLMs/SLMs in production with fine-tuning techniques (LoRA, QLoRA, DPO)
    • Implement quantization strategies (INT8, INT4) and model distillation for edge deployment
    • Build evaluation frameworks including LLM-as-judge systems and regression testing
    • Design streaming architectures for real-time LLM responses (SSE, WebSockets)
    • Create semantic caching and embedding-based retrieval systems
    • Develop GraphRAG and long-context handling strategies (100k+ tokens)
  • System Architecture & Engineering:
    • Design scalable microservices with comprehensive observability (LangSmith, Arize, custom telemetry)
    • Build secure multi-tenant systems with prompt injection prevention and output validation
    • Implement cost optimization through intelligent model routing and fallback strategies
    • Develop document processing pipelines with OCR and layout understanding
    • Create event-driven architectures for real-time shipment tracking and exception handling
  • Data & Infrastructure:
    • Build data pipelines for training data curation, synthetic generation, and PII masking
    • Implement RLHF/RLAIF feedback loops for continuous improvement
    • Design experiment tracking and model registry systems (MLflow, DVC)
    • Optimize inference costs through batch processing and spot instance utilization
    • Establish model governance, audit trails, and compliance frameworks

Qualifications

  • 8+ years software engineering, 3+ years in production AI/ML systems
  • Expertise in Python, PyTorch/JAX, and AI frameworks (LangChain, Transformers, PEFT)
  • Experience with LLMs (GPT-4, Claude, Gemini) and SLMs (Phi, Llama, Mistral)
  • Hands-on experience with:
    • Fine-tuning techniques (LoRA, QLoRA, DPO, RLHF)
    • Model optimization (quantization, distillation, pruning)
    • Vector databases and RAG architectures
    • Streaming systems and real-time processing
    • Security measures (prompt injection prevention, jailbreak detection)
  • Strong background in distributed systems, Kubernetes, and cloud platforms

Requirements

  • Experience with document intelligence and multi-modal AI systems (nice to have)
  • Understanding of supply chain operations, EDI/API integrations (nice to have)
  • Knowledge of token economics and consumption-based pricing models (nice to have)
  • Familiarity with enterprise compliance requirements (GDPR, CCPA, SOC2) (nice to have)

Benefits

  • Competitive compensation with stock options
  • Outstanding benefits and a collaborative culture for all employees
  • 5 global recharge days, in addition to generous PTO and standard holidays
  • Parental leave for all parents
  • Annual wellness stipend and volunteer days
  • Medical benefits start on the first day of employment (for India)
  • 36 PTO days (Sick, Casual, and Earned), 5 recharge days, 2 volunteer days (for India)
  • Home Office setups and Technology reimbursement (for India)
  • Mental Wellness support and guidance (for India)
  • Ongoing learning & development opportunities (Professional development program, Toast Master club, etc.) (for India)
