Principal AI Architect, Agent Systems

Lead the architecture for FourKites’ AI agents, from models and context management to evaluation. Build the platform behind AI-powered supply chain digital workers.

विवरण

  • Own the architecture for FourKites AI agents, covering execution, context, models, and evaluation.
  • Set the agent reference architecture for loops, tool use, state, checkpoints, retries, recovery, safeguards, permissions, and human handoffs.
  • Design durable, multi-step workflows that cross context windows and recover from tool, carrier API, and model failures.
  • Choose the right approach for each problem, from frontier or open-weight models to fine-tuned encoders or conventional code.
  • Manage model routing, per-task costs, and latency targets across the agent fleet.
  • Connect agents to Kafka, microservices, Postgres, customer APIs, and MCP servers.
  • Define context-window standards for prompts, tools, retrieved content, memory, and prior turns within token limits.
  • Create shared tools for retrieval, context compaction, summarization, sub-agent isolation, prompt caching, and persistent memory.
  • Investigate context failures and turn solutions into reusable execution patterns.
  • Develop offline evaluation systems using production traces, code-based checks, calibrated LLM-as-judge grading, and CI regression suites.
  • Develop online evaluation with production scoring, quality measures, drift monitoring, shadow and A/B releases, feedback signals, and quality alerts.
  • Link evaluation measures to outcomes such as tracking accuracy, automated exception resolution, and appointment fill rates.
  • Review designs and pull requests, document architecture and operating playbooks, and mentor staff and senior engineers.
  • Follow model and tooling developments, run experiments, and recommend whether to build, buy, or wait.
  • Work with Product, Solutions, and Customer Success to turn field issues into platform improvements.

आवश्यकताएँ

  • Have architected and operated an LLM agent system serving real users and production traffic, including tool calls, multi-step workflows, failure handling, and escalation to people.
  • Have owned an LLM agent system after launch, managing incidents, cost, and latency.
  • Bring deep machine learning knowledge, including attention, positional encodings, encoder and decoder architectures, tokenization, and KV caches.
  • Have trained or fine-tuned encoder models, such as BERT-family models, sentence embeddings, bi-encoders, and cross-encoder re-rankers.
  • Understand contrastive training, distillation, and quantization.
  • Have managed token budgets and built retrieval and memory for agents.
  • Have used context compaction and sub-agents, and measured quality as context windows fill.
  • Have built agent execution layers with loops, tool dispatch, state and checkpoints, interruption and recovery, sandboxing and permissions, safeguards, and model routing.
  • Be fluent in MCP, structured outputs, and streaming.
  • Have built offline and online evaluation suites covering datasets, graders, LLM-as-judge calibration, CI regression gates, production scoring, trace sampling, drift monitoring, shadow deployments, and feedback loops.
  • Bring 10+ years of software or machine learning systems experience, including 3+ years building with LLMs.
  • Have strong, hands-on Python skills.
  • Be comfortable reading and reviewing Java or TypeScript services.
  • Have production experience with AWS or GCP, containers, Kubernetes, and event-driven systems.
  • Communicate effectively in writing and in conversation.
  • Preferred: experience in supply chain, logistics, or transportation.
  • Preferred: experience with Document AI, OCR, layout models, and extracting data from bills of lading, invoices, and proof-of-delivery documents.
  • Preferred: experience building voice or email agents that act for a business.
  • Preferred: experience with agent security, including prompt-injection defense, tool permissions, and tenant data isolation.
  • Preferred: experience with Claude, GPT, Gemini, open-weight models, and model-serving stacks.
  • Preferred: publications, talks, or open-source contributions on agents, retrieval, or evaluation.
