Backend Develoepr

Role & Responsibilities

As a Senior GenAI Engineer you will own the AI layer of our product — building the features that make Zenskar intelligent. This is not a research role and not a prompt-engineering role. You will build production AI systems that enterprise clients depend on, which means reliability, observability, and rigorous evals matter as much as the AI capability itself. You own the full vertical — the model, the pipeline, and the UI.

• Build and own CS Copilot — a real-time assistant for customer success teams, spanning STT pipelines, live transcription, and LLM-powered suggestions
• Build LLM-powered document understanding features — extracting structured, reliable data from unstructured enterprise documents
• Own AI feature UIs end-to-end — you build the interface, not just the model integration layer
• Design and maintain an eval framework — define what 'working' means for each AI feature and catch regressions before users do
• Drive model selection and integration decisions — choosing the right provider and approach for each use case, managing latency and cost
• Own AI platform reliability — observability, fallback behaviour, and graceful degradation when models fail
• Work closely with product, customer success, and the full-stack engineer — AI features only matter if they are usable and trusted by real users

THE IMPACT YOU'LL MAKE-

• You will define what AI means at Zenskar — the features you ship will be the most visible and differentiated parts of the product
• CS Copilot, if done well, changes how enterprise customer success teams operate every single day — this is a high-stakes, high-visibility surface
• You will establish the engineering culture around AI reliability at Zenskar — evals, observability, and disciplined iteration
• Your work will directly accelerate enterprise deals — AI features are increasingly a buying criterion for our clients
• You will be the person who brings engineering rigour to a domain where most companies ship demos and call it a feature

• Mandatory (Experience 7) – Must have strong coding and system design skills, not just prompt engineering or experimentation

Organizational Overview

It is a super app to digitize India’s 50M+ sales agents where they can get access to relevant products & services, receive training through interactive videos on “how to sell, what to sell and whom to sell”, and earn money. For businesses, we help them save a huge effort in managing and training these agents and help them increase their reach to every nook and corner of the country.

India is a trust deficit market which cannot be accessed through Internet Marketing on Facebook and Google as the majority of the customers need training, push, motivation and a primer on why and how to use a product.

To solve this problem, traditional industries like BFSI, Telecom, Automobile, Real Estate etc. use 50M+ frontline sales executives to drive distribution. We believe that not just for these traditional industries but also for emerging companies in FinTech, EdTech etc these agents will play a pivotal role in accessing trust deficit customers.

They have grown to a  100,000+ agent network across India (growing 50% MoM). One Code is funded by tier1 VC’s and angels in India.
