Customer Success Engineer - Internship

Overview

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 in-store experience online: extensive knowledge about the brand and its products; tailored advices based on previous orders. We started with Q&A on product page through a Shopify application. In 2025 we aim to deploy to new e-commerce engines (Prestashop, Salesforce Commerce Cloud, custom engine) and add new features such as product comparison across the store, AI search, and many more. We wrote the first line of code in January 2024, started commercializing in September 2024 and have now more than 50 paying customers. Mission As a Customer Success Engineer at Dialog, you will ensure our customers can reliably use Dialog in production by owning the investigation and resolution of technical issues (especially add-to-cart), and by turning observability signals (Langfuse traces) into concrete product and operational improvements.

Responsibilities

Add-to-cart issue resolution (Shopify) Triage and resolve add-to-cart bugs impacting client deployments; identify root causes (theme-specific behavior, DOM updates, Section Rendering API, AJAX responses, event listeners, overlay/drawer regressions, variant availability logic); deliver fixes end-to-end: reproduce → implement patch → validate → document workaround when needed. Faster OPS execution & reduced support load Reduce time-to-resolution for OPS tickets related to integrations and add-to-cart; maintain a clear playbook (how to diagnose, where to look, common patterns) so the OPS team can self-serve for known cases. Langfuse-driven investigation of client queries Investigate Langfuse traces to understand client questions, context, tool usage and failures; produce actionable conclusions (misconfig, missing data, retrieval issues, tool errors, prompt/config gaps); communicate findings clearly to product/engineering, and track fixes to closure. Technical triage & documentation Improve day-to-day debugging signal for OPS by producing high-quality ticket writeups (repro steps, expected vs actual, screenshots, trace links); maintain and iterate on runbooks (common add-to-cart patterns, theme-specific fixes, Prestashop edge cases). Customer-facing technical enablement Help customers/partners implement recommended fixes (docs, snippets, validation steps); support onboarding of complex stores (custom themes / edge cases) without blocking sales cycles; handle recurring support questions (reports, invoices, etc.) by building lightweight processes and templates.
