SSummary

As a Custom Software Engineer Lead, a typical day involves creating tailored software solutions by designing, coding, and improving various components within systems or applications. The role requires working with contemporary development frameworks and following agile methodologies to ensure the delivery of scalable and efficient software that meets unique business requirements. Collaboration with team members and adapting to evolving project needs are integral parts of the daily workflow, fostering innovation and continuous improvement in software products.

Roles & Responsibilities

• Design and implement multi-agent orchestration pipelines using LangGraph state

machines — conditional routing, self-healing retry loops, and supervisor / sub-agent

hierarchies

• Engineer retrieval-augmented generation (RAG) systems: chunking, embedding

pipelines, vector search, re-ranking, and token-budget management

• Model knowledge graphs (entities, relationships, ontologies) and build hybrid

retrieval that fuses graph traversal with vector similarity

• Govern prompts through a versioned prompt registry implement multi-model

routing by task/stage with fallback strategies

• Build LLM evaluation harnesses — golden datasets, automated scoring, regression

gates, and hallucination/grounding checks

• Implement guardrails: schema-constrained (structured/JSON) output, validation,

self-correction, and safety filtering

• Serve and optimize on-prem LLMs via vLLM alongside cloud OpenAI-compatible

APIs — batching, streaming, context-window management

• Instrument the AI stack for observability — token usage, latency percentiles, cost

attribution, and trace/provenance logging

• Integrate agentic interoperability protocols (A2A, MCP) and connect agents to

enterprise tools via REST/GraphQL

Professional & Technical Skills

Must To Have Skills

Core AI & LLM

• Python 3.10+ — production async code, FastAPI,

output, self-healing retry loops

• Agent frameworks — LangGraph / LangChain (state machines, tool calling,

orchestration)

• Model serving — vLLM, TGI, or OpenAI-compatible inference APIs (streaming,

batching)

Evaluation & Reliability

• LLM evaluation — eval datasets, automated scoring, regression testing,

hallucination/grounding metrics

• Guardrails — output validation, schema enforcement, safety filtering

Nice-to-Have Skills

• -Ontology modeling — taxonomies and relationship schemas for domain knowledge
• -Dual-tier agent memory — Redis (L1) + mem0 (L2), semantic recall, context
• consolidation

• DAG workflow compilation — topological sorting, cycle detection, parallel execution

(Ray)

• A2A / MCP / AG-UI — emerging agentic interoperability protocols
• Fine-tuning / LoRA / quantization — model adaptation and optimization
• RAG architecture — chunking strategies, re-ranking, context assembly, grounding
• Vector databases — Qdrant, Pinecone, or Weaviate embedding pipelines and

semantic search

• Embeddings — sentence-transformers or equivalent similarity tuning
• Knowledge graphs — Neo4j / Cypher, entity-relationship modeling, graph traversal
• 7-8 years professional software engineering experience, with 3+ years building LLM,

agent, or ML systems in production ,5+ years on Python .

• Strong async Python and hands-on experience with an agent framework

(LangGraph, LangChain, or equivalent)

• Demonstrated experience with RAG, vector search, or knowledge-graph retrieval
• Track record of taking AI features from prototype to grounded, evaluated,

production-ready systems

• Fluent communication

Additional Information
