Customer Success Engineer — Full-time

At Dialog, we are on a mission to build the best sales agent for e-commerce.
We believe generative AI is the perfect opportunity to bring the best of the in-store experience online:
extensive knowledge about the brand and its products
tailored advice based on previous orders
We launched on Shopify with Q&A; on product pages. In 2026, we’re scaling Dialog to new e-commerce engines and upgrading the experience with smarter qualification, an agent that runs across the entire store, and AI-powered search.
We wrote our first line of code in January 2024, started commercializing in September 2024, raised $4.4M in November 2025 and now have more than 100 paying customers.

The role
We are looking for a Customer Success Engineer to be the first line of defense for our customers’ day-to-day technical issues, and to help us keep support quality high as we scale.
You will own our L1/L2 operations end-to-end across the technical topics that make Dialog work in production: Shopify and PrestaShop integrations, configuration, front-end behavior,



tracking and events, and AI-behavior questions.

L1 — first line: triage, recurring requests, known fixes, and documented responses.
L2 — second line: deeper reproduction and diagnosis, undocumented cases, before escalating to engineering.

The challenge as Dialog grows fast: keep support fast and high-quality while making sure it doesn’t scale linearly with revenue, by resolving issues well and removing their root cause over time.
You will also investigate how our AI agent behaves in the real world: reading our AI agent traces end-to-end, spotting failure modes such as retrieval issues, tool errors, prompt gaps, or missing context, and translating what you find into concrete improvements for product and engineering.
And you will turn recurring problems into leverage: playbooks, runbooks, self-serve docs, and automation, including AI-assisted triage and responses, so the team and our clients stop hitti
