Role Mandate
We are soliciting applications for a
Senior AI Prompt Engineering Lead
to architect, govern, and optimize high-fidelity Large Language Model (LLM) systems. This role is positioned at the intersection of
Agentic AI
and
Hiring Automation
, requiring a sophisticated approach to building systems that recruit, evaluate, and interact with human talent autonomously.
This is not a content generation role; it is a
systems engineering role
. You will be responsible for designing the cognitive architecture of our platform, utilizing frameworks such as LangChain and LangGraph to build deterministic, scalable, and reasoning-capable agents for production environments.
Core Responsibilities
1. Advanced Prompt Architecture & Cognitive Modeling
Strategic Design:
Engineer production-grade prompt infrastructures for complex workflows, including candidate evaluation, resume parsing, interview automation, and autonomous stakeholder communication.
Methodology Implementation:
Deploy advanced prompting paradigms—including Chain-of-Thought (CoT), Tree-of-Thought, Self-Consistency, and Instruction Hierarchies—to ensure high-precision reasoning.
Constraint Engineering:
Architect robust guardrails and instruction-following protocols to maintain system safety, prevent jailbreaks, and ensure strict adherence to hiring rubrics.
2. Agentic AI & Workflow Orchestration
System Construction:
Build and manage stateful, multi-agent workflows using
LangGraph
and
LangChain
.
Decision Logic:
Design complex, multi-step decision trees that incorporate human-in-the-loop (HITL) checkpoints, autonomous error recovery, and conditional branching.
Operational Efficiency:




Optimize execution paths for latency and token cost without compromising the depth of analysis or system reliability.
3. RAG & Knowledge-Grounded Systems
Pipeline Engineering:
Architect Retrieval-Augmented Generation (RAG) pipelines that ensure high-fidelity context injection, minimizing hallucinations through rigorous source attribution.
Vector Strategy:
Manage integration with vector databases (Pinecone, Weaviate, Chroma) and implement advanced retrieval strategies such as semantic re-ranking, query expansion, and context compression.
4. Governance, Evaluation & Optimization
Quality Assurance:
Define and implement automated evaluation frameworks (LLM-as-a-Judge) to conduct regression testing on prompts and measure output drift.
Model Selection:
Make strategic decisions regarding model routing (GPT-4 vs. Claude vs. Gemini) and determine the viability of PEFT/LoRA fine-tuning versus context-window optimization.
Standardization:
Establish strict documentation standards for prompt versioning and reproducibility to ensure enterprise-grade compliance.
Candidate Profile
Technical Prerequisites:
Deep Proficiency:
Extensive hands-on experience with
LangChain
and
LangGraph
is non-negotiable.
LLM Fluency:
Mastery of prompt engineering for frontier models (GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro).
Production Experience:
A proven track record of deploying independent AI applications, specifically within
HR Tech,



Recruitment Automation, or Workflow Orchestration
.
Architectural Vision:
Ability to conceptualize and build end-to-end AI systems, moving beyond isolated prompts to integrated cognitive architectures.
Preferred Qualifications:
Academic Pedigree:
B.Tech/M.Tech from top-tier institutes (IITs, IIITs, BITS, or equivalent global institutions) is highly preferred.
Startup DNA:
Experience operating in high-velocity, product-first environments where ownership and autonomy are paramount.
Desirable Skills (Bonus):
Experience with OpenAI Assistants API and Function Calling.
Familiarity with LLM observability platforms (LangSmith, Weights & Biases, PromptLayer).
Expertise in adversarial prompting and security hardening for LLMs.
Application Process
Interested candidates are invited to submit their qualified profile and a brief portfolio of relevant AI/Agentic projects. Please highlight specific instances where you have engineered complex reasoning flows or automated decision-making systems.
Your Experience:
Bachelor's or Master's degree in Computer Science, AI, or related discipline.
Proven experience leading AI projects, particularly in prompt engineering.
Strong portfolio or case studies showcasing your work in AI and recruitment automation.
Understanding of user-centered design principles and how to apply them in AI settings.
Experience collaborating with cross-functional teams to deliver successful AI applications.
