Hire chatbot developers who ground every answer in your own content
Hire chatbot developers in India who build support bots, sales assistants and internal copilots on GPT, Claude and open-weight models. Each bot they build retrieves answers from your help centre and documents, hands over to a person when it should, and is tested against your recent customer questions before launch.

What a chatbot developer does on your team
Most of the effort sits outside the chat window, in the retrieval, integrations and testing that decide whether customers trust the bot.
- What does a chatbot developer do?
- A chatbot developer builds conversational software that answers questions and completes tasks in chat or voice. Modern chatbot work covers retrieval over a company's own content, prompt and tool design, integrations with systems such as CRMs and ticketing tools, escalation to human agents, and the evaluation and monitoring that keep answers correct after launch.
Hire conversational AI developers by role
Hire one developer for a single bot, or pair roles when the bot has to read your content and act in your systems.
Support chatbot developer
Builds tier-1 support bots on web, in-app and WhatsApp that answer from your help centre and ticket history.
See AI chatbot developmentRAG and knowledge engineer
Chunking, embeddings, hybrid search and citations, so the bot quotes your policy and says so when it has no answer.
See RAG developmentIntegration developer
Connects the bot to order lookups, bookings, refunds and CRM records through APIs, function calling or MCP servers.
Internal copilot developer
Builds HR, IT helpdesk and policy copilots behind SSO, where each employee sees only the content they are allowed to read.
Multilingual conversation designer
Runs one backend for several languages and tunes response length, tone and escalation wording per channel.
Chatbot QA and reliability engineer
Builds the eval set, traces every conversation and reviews failures each week so fixes go back into the tests.
Four gaps a chatbot developer's CV will not show you
Plenty of developers can wire a chat window to a model API. These four gaps decide whether the bot survives its first month with customers, and our vetting checks for each one.
Answers from model memory
The bot sounds sure of itself and gets your refund policy wrong. Our developers retrieve every factual answer from your content and show the source.
No way out for the customer
Users loop through the same replies until they give up. Escalation triggers are designed up front, and the handoff passes the transcript to your agent.
No test set
Every prompt change is a guess, and regressions reach customers first. Developers build an eval set from your recent customer questions and run it on every change.
Demo-only experience
A notebook demo hides rate limits, messy inputs and the questions nobody planned for. We check production chatbot and LLM work through references and work samples before shortlisting.
How we vet chatbot developers
Every chatbot developer is a salaried employee on the ScalaCode payroll in India. These checks apply before a profile reaches you and after the developer joins.
Our technical interview
Every engineer passed our technical interview and coding test before joining ScalaCode, with LLM, retrieval and API questions for chatbot roles.
Earlier work checked
Past chatbot, RAG and LLM builds are reviewed through references and work samples before we put a developer forward.
Your interview and test
You interview each shortlisted developer and can set your own exercise. Nobody joins until you choose them.
Tests and staging
Automated tests and the eval set run on every change, and releases go through staging before they reach your users.
IP from the first commit
The code, prompts and eval data are yours from the first commit, and NDAs are standard on every engagement.
How hiring a chatbot developer works
From first call to first commit in about two weeks for most hires. A business consultant reads your brief first, so the profiles you see match the bot you need.
Send us 20 recent customer questions
We will match a chatbot developer who has built a bot for questions like yours, with profiles within 48 hours.
Models, frameworks and channels our chatbot developers use
Developers pick the model per task, based on your data, your latency target and your budget.
Cost to hire chatbot developers
Dedicated chatbot developers start from $1,799 a month, full-time. Senior developers start from $2,499 and tech leads from $3,499.

Hire chatbot developers FAQs
Bring the questions your customers ask most to the call.
How much does it cost to hire a chatbot developer?
Dedicated chatbot developers start from $1,799 a month for a mid-level engineer, $2,499 for a senior engineer and $3,499 for a tech lead. Each rate is full-time, 160 hours a month, billed monthly. If you want us to build the whole bot as a project, a production LLM application starts at $14,999.
How do your chatbot developers stop the bot from making things up?
They ground every factual answer in your own content through retrieval, show the source, and have the bot say it does not know when nothing relevant comes back. An eval set built from your recent customer questions runs on every change, so a regression shows up in testing before a customer sees it.
Which chatbot platforms and LLMs do your developers work with?
Our developers work with GPT, Claude, Gemini, Llama and Mistral, and use LangChain, LlamaIndex, LangGraph and MCP. They deploy to web widgets, WhatsApp, Slack, Microsoft Teams and Messenger, and connect to Zendesk, Intercom, Freshdesk, HubSpot and Salesforce.
Can a chatbot developer fix a bot another team built?
Yes. The developer starts by reading recent conversations and the prompts, then builds an eval set from the failures. Fixes to retrieval, prompts and escalation go in one at a time, with the eval set showing whether each change helped.
How fast can a chatbot developer start?
Matched profiles reach you within 48 hours of the first call. After you interview and choose, onboarding takes about a week, so most developers make their first commit around two weeks after that call.
Can we interview the chatbot developer first?
Yes. You interview every shortlisted developer yourself, on your schedule, and you can set your own exercise. If none of them fit, we send more profiles.
Should we hire a chatbot developer or buy a chatbot platform?
A hosted platform suits FAQ-style bots on one channel with little integration. Hire a developer when the bot has to act in your systems, answer from private documents, follow your security rules or run on your own cloud account. If the bot also has to answer the phone, add a voice AI engineer.
Who owns the chatbot code, prompts and conversation data?
You do. We sign an NDA before sharing profiles, and the code, prompts, eval sets and conversation logs stay in your repositories and cloud accounts from the first commit.
Which time zones do your chatbot developers cover?
Our developers work from India and overlap with US, UK and European business hours. For US clients the standard overlap is 4 to 6 hours of the US working day.
Your engineers work in your hours
Timezone overlap is built in. Your matched engineers keep 4 to 6 hours of daily overlap with US hours and a full working day with the UK, Europe and the Middle East, so standups, reviews and fixes land during your working day.
What stood out to us as most impressive and unique about ScalaCode was their ability to humanize complex AI.
