Senior Developer

Are you a senior developer who enjoys building complex, high-impact software? Do you want to work in a team that values quality, autonomy, and craftsmanship? Then we’d love to hear from you.

Who are we?

Seamly makes customer contact smarter by giving chatbots a voice. We enable organizations to easily extend their existing conversational platforms to the phone channel — making their digital assistants available not only via chat, but also by phone.

By adding voice to existing chatbots, we help organizations deliver a consistent, personal experience across every channel. This reduces the pressure on our customers’ service teams and makes customer interactions faster, more efficient, and more human. With Seamly, organizations can effortlessly scale to voice without having to overhaul their existing technology stack.

We are a remote-first organization, work in a results-driven way, and strongly believe in ownership, transparency, and collaboration towards sustainable growth.
