Customer Success Engineer Internship - French Speaker

PARIS, 75
il y a 7 jours

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 engine (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.

Typical time allocation

  • 30% – Investigation & improvements from Langfuse traces (quality, tooling, playbooks)
  • 20% – Customer-facing interactions with the CSM team (syncs on priorities, customer comms, follow-ups)
  • 10% – Documentation, enablement & internal tooling for OPS

What you will do

Your scope is end-to-end: from triage and reproduction to shipping fixes, documenting workarounds, and closing the loop with product/engineering.

Key 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.

Requirements

  • Education: currently pursuing an engineering degree (or equivalent) — internship / end-of-studies internship
  • Experience: first experience (internship/apprenticeship/side projects) in a technical, customer-facing or support/solutions context is a strong plus — we care more about mindset than years
  • Technical skills: Web debugging fundamentals (DevTools, network, DOM inspection, JS/TS basics, async behavior)
  • Comfortable reading small codebases and shipping pragmatic patches
  • Interest in e-commerce storefront behaviors (themes, dynamic DOM, tracking/events)
  • Ability to run structured investigations from signals (traces/logs); Langfuse is a plus
  • Soft skills: Ownership & reliability: you follow issues to closure with support from the team
  • Clarity: you write crisp summaries and communicate well with non-technical stakeholders
  • Pragmatism: you optimize for customer impact and time-to-resolution
  • Curiosity & coachability: you learn fast, ask good questions, and iterate
  • English: B2 minimum (work environment is in English)
  • Nice to have: basic backend/infra literacy (APIs/HTTP, logs, observability) and familiarity with Shopify/Prestashop ecosystems

Hiring process

  • Chat with Paul-Arthur who leads Account Management and Customer Support
  • Technical interview with our CTO Louis

Team-first culture

The whole team gathers monthly for events, 2 times per year for off-sites.
