Senior AI Developer, GTM Systems
TL;DR
Klaviyo's looking for someone to sprinkle AI magic into their sales tools—think smart assistants that make sellers' lives easier, not harder.
Your canvas: wire up AI agents between Salesforce, AWS, and Google Cloud; make them talk nice to each other and actually help humans sell better.
Daily beat: code in Python or JavaScript, tune LLM prompts until they sing, catch errors before they bite, and keep the whole system humming like it should.
Who fits: 3–5 years building stuff that works, comfortable with cloud platforms, and already played with AI tools enough to know their quirks.
Simple truth: this isn't about AI for AI's sake—it's about making sales tools that actually help people sell. If that lights you up, this is your jam.
