How does our chatbot developer hire-a-dev work

Here's how hiring a chatbot developer through Width works — from resumes to a same-day onboarding.

Choose your developer

We send you resumes plus the exact chatbot projects each developer has shipped — voice bots, RAG assistants, agents. You see production-level work and research, not just a CV.
‍
Building a team? Request as many highly skilled engineering resources as you need.

Choose a number of hours per month

Each profile shows availability, hourly rate, and seniority. Work monthly, part-time or full-time, with US-based or overseas engineers to fit your budget and time zones.

Engagements start at 10 hours per week.

Start building new agentic systems

If the developer has the availability you're looking for they can start the same day. We'll start the onboarding process and set up an introduction interview!

Find out they're not a fit for your use case? Project change scope? Just request a different dev and we'll quickly align.
