Overview

What Hire Chatbot Developer looks like with us

From scoping call to go-live, our Chatbot Developer engagements are designed for teams that care about what actually ships. Security and privacy are built in: NDA-first, least-privilege IAM, EU or US data residency, VPC-isolated deployment options. Every engagement starts with a mutual NDA, a scoping conversation with a senior engineer, and a written proposal within one week. All work product, source code, and documentation is assigned to you on payment — no vendor lock-in, ever.

FAQs

Common questions

How are your Chatbot Developers vetted?

Every engineer goes through a 90-minute technical + systems-design interview with a senior from our team, plus reference checks. We record interviews so you can audit the process.

Can I interview the engineer before committing?

Yes — we welcome it. Your team gets a 30-60 minute technical interview before we confirm the engagement. If the fit isn't right, we find another.

Who owns the IP?

You do. All code, documentation, model weights, and deliverables are assigned to you on payment. Our master service agreement spells this out explicitly.

Do you sign NDAs before a scoping call?

Yes — standard practice. We circulate a mutual NDA before any detailed conversation about your product, data, or roadmap.
