Who We Are

Established in 2015, ClickPost is Asia's largest Logistics Intelligence Platform, working with companies such as Walmart, Nykaa, Meesho, Adidas etc. to help them improve post purchase customer experience.

We have been profitable for the past 5 years and are backed by some of the biggest investors around and are growing 2x year on year.

We are one of the rare startups working at cutting edge technology, with enormous scales and a brand name that is well respected in Indian Saas and e-commerce world. Our core values of transparency, continuous learning, ownership, and speed have fostered a dynamic culture. With several ex-startup founders on the team, we've created a workplace that’s both engaging and rich with learning opportunities.

About the Role:

You’ll own the end-to-end lifecycle of AI voice agents, designing and optimizing prompt flows that drive real customer conversations across multiple use cases.
This role sits at the intersection of product, AI, and operations; where you’ll continuously refine agent behavior using data, evaluation frameworks, and real-world feedback. If you enjoy solving for clarity, control, and scale in AI systems, this is where you build and ship impact fast.

Key Responsibilities:

Own and drive the end-to-end lifecycle of AI Voice Agents at ClickPost - from prompt design and flow creation to deployment, evaluation, and continuous optimization.
Design, refine, and optimize prompt flows for multiple agent use cases (NDR, Order Confirmation, NPR, NPS, Inbound Support), ensuring clarity, brevity, tone alignment, and objective completion.
Build and enforce behavioral guardrails for agents, including tone control, hallucination prevention, fallback handling, and edge-case management (e.g., emotional users, repetitive intents, interruptions).
Define and implement a modular evaluation framework for AI agents across:
Pre-call (prompt quality, edge-case readiness)
Live-call (response accuracy, sentiment handling)
Post-call (intent fulfilment, outcome tracking)
Leverage “LLM as a Judge” frameworks and transcript analysis to automate evaluation and continuously improve agent performance.
Analyze call logs, transcripts, and performance metrics to identify failure points (e.g., STT errors, drop-offs, misalignment) and drive prompt-level improvements.
Own and maintain a centralized prompt library, documentation, and version-controlled playbooks for all agents.
Develop new AI agent use cases and flows (e.g., NPR, NPS, inbound support), including prompt design for edge cases and real-world scenarios.
Enable multilingual capabilities for agents (Tier 2/3 languages), including prompt localization, validation, and mid-call language switching.
Collaborate closely with Product, Engineering, Data, and Operations teams to integrate prompt logic into production systems and improve overall system performance.
Support client-specific customizations by adapting agent tone, behavior, and flows based on brand requirements (D2C, enterprise, luxury, etc.).
Continuously explore and experiment with new LLM models, prompting techniques, and AI capabilities to improve agent quality and efficiency.
Contribute to building organization-wide frameworks for designing, scaling, and monitoring AI agent products across use cases.

Skills & Qualifications:

2–5 years of experience in prompt engineering, AI product development, conversational AI, or related roles in a SaaS / tech environment.
Strong understanding of LLMs, prompt design techniques, and context engineering for generating reliable and high-quality outputs.
Experience working with AI tools, voice agents, chatbots, or automation workflows in real-world use cases.
Strong analytical and problem-solving skills; ability to evaluate model outputs, identify gaps, and iteratively improve performance.
Comfortable working with technical concepts like APIs, webhooks, logs, transcripts, and evaluation metrics (coding not mandatory but preferred).
Strong written and verbal communication skills with high attention to detail and clarity.
Ability to work in a fast-paced, ambiguous environment with high ownership and end-to-end responsibility.

Nice to Have:

Experience working on voice-based AI agents or conversational AI systems.
Familiarity with evaluation frameworks, LLM-based grading (“LLM as a judge”), or automated testing systems.
Exposure to multilingual AI systems or regional language adaptation.
Experience in building AI-driven workflows, automation tools, or internal productivity systems.
Prior experience in logistics, e-commerce, or customer experience domains.

What You’ll Learn:

How to build and scale production-grade AI voice agents across multiple real-world use cases.
How to design robust prompt systems with guardrails, evaluation layers, and continuous optimization loops.
How to translate complex business workflows into AI-driven conversational experiences.
How to build organization-wide frameworks for AI product development, evaluation, and monitoring.
How to work closely with enterprise clients and build highly personalized, high-impact AI solutions.

What You Can Expect:

Culture:

We value velocity in all things we do. You would be expected to move fast, experiment and be updated with the newest technologies
