Job description

Responsibilities

• Build and Operate AI Middleware: Implement, and manage Model Context Protocol (MCP) servers, gateways, and API wrappers that securely expose enterprise systems, tools, and data for AI agent consumption.
• Build and Govern Agentic Workflows: Deploy and extend agentic AI platforms (e.g., LangGraph, LangChain) to deliver resilient orchestration, enforcing governance, tracing, audit logs, and human-in-the-loop controls.
• Develop Enterprise Data & Context Pipelines: Build scalable pipelines for parsing, cleaning, embedding, and storing structured and unstructured enterprise data (text, code, multimedia) to enable retrieval-augmented generation and domain‑specific agent knowledge.
• Productize and Optimize AI Services: Translate prototypes into production‑grade microservices (Python/TypeScript, Kubernetes, CI/CD), optimizing for latency, throughput, resilience, and token/cost efficiency.
• Ensure Security, Compliance, and Reliability: Engineer AI middleware and workflows that meet enterprise standards for safety, governance, compliance, and fault tolerance, with built‑in monitoring, telemetry, and automated evaluation harnesses.
• Partner multi‑functionally with architects, platform teams, and product owners to deliver business‑aligned AI solutions, while staying at the forefront of emerging LLM and middleware trends.

Qualifications

• 6+ years of software engineering experience, including approximately 2 years working on ML, data, or LLM‑focused systems.
• Proficiency in Python or TypeScript (ideally both) with strong software‑engineering fundamentals (testing, design patterns, observability, performance tuning).
• Practical knowledge of ML/GenAI concepts: embeddings, vector search, prompt engineering, fine‑tuning, and evaluation metrics.
• Solid understanding of workflow orchestration frameworks for LLM/GenAI pipelines.
• Hands‑on experience with data‑pipeline tooling and batch/stream ETL.
• Solid understanding of cloud platforms (AWS preferred), containerization (Docker, Kubernetes), and infrastructure‑as‑code (Terraform, CDK).
• Excellent communication skills and a proven ability to collaborate across teams in a fast‑paced environment.

Domain Expertise

• LLM tooling: LangChain, LangGraph, LlamaIndex, Hugging Face Transformers, OpenAI or Anthropic APIs
• Data stores: Postgres, DynamoDB, Redis, and vector databases such as Pinecone, Weaviate, FAISS
• Observability: distributed tracing, metrics dashboards, cost monitoring for token‑based services
• Security & Responsible AI: PII redaction, content‑safety filters, bias evaluation

Bonus

• Proficiency in Go
• Experience with multimodal or edge inference
• Contributions to GenAI open‑source projects
