Description du poste

About the Role

We're looking for a motivated end-of-study intern (Bac+4/Bac+5, engineering school or university) to join our Engineering team for 6 months and contribute to real product challenges — not a side project, not internal tooling no one uses.

You’ll be embedded in a product squad, working alongside confirmed engineers, a Product Manager, and a Tech Lead who will mentor you throughout your internship. You’ll get hands‑on exposure to our Salesforce ecosystem and learn how a modern engineering team ships software at scale.

This internship is a genuine opportunity to grow fast and, if things go well, a potential path to a full‑time role.

Your Team

You’ll join a tech team of ~20 engineers organised into 4 product squads. Each squad owns a domain and ships continuously. We value:

• Clear ownership and accountability
• Pragmatic engineering decisions
• Strong feedback loops (code reviews, monitoring, retros)
• Continuous improvement in craft and delivery

What You’ll Do

• Learn and contribute to our Salesforce platform: data model, automation logic, and backend features with Apex
• Participate in the design and implementation of integrations between Salesforce and internal/external services
• Contribute to backend services (TypeScript/Node.js) with guidance from your squad
• Work with Product and Design to understand user needs and translate them into working software
• Write clean, tested code and take part in code reviews
• Explore AI‑assisted development tools (Cursor, Claude Code, GitHub Copilot) to accelerate your learning and output

What We’re Looking For

Required

• Currently enrolled in a Bac+4 or Bac+5 programme (engineering school, university master's) — end‑of‑study internship preferred
• Solid programming fundamentals: you know how to write clean code, debug, and think through a problem
• Exposure to at least one backend language (Java, Python, C#, TypeScript, or similar)
• Genuine curiosity about how software systems work in production
• Good communication in French and English

Greatly Appreciated

• Any prior exposure to Salesforce or Apex (coursework, personal project, or previous internship)
• Experience with REST APIs and understanding of web service integration
• Familiarity with Git and basic CI/CD concepts
• Interest in the electric mobility / energy transition space
• TypeScript or Node.js experience

Our Tech Stack

• CRM & Operations: Salesforce (Apex, Flows, Process, Builder)
• Backend: TypeScript, Node.js, microservices
• Infrastructure: Docker, Kubernetes, cloud‑native
• Frontend: Vue.js, React, Next.js
• Python, PHP, NoCode tooling

Why Join Us

• Mission‑driven work: Every line of code contributes to accelerating the EV transition across Europe
• Real ownership: Junior doesn't mean spectator — you’ll ship meaningful features quickly
• AI‑first culture: We embrace the best tools and expect everyone to keep learning
• Tight‑knit team: ~20 engineers who genuinely enjoy working together
• Paris centre office, hybrid setup
• Strong product ambition and a fast‑moving roadmap
• Tech watch, learning budget, and an environment that values curiosity

How We Hire

We keep our process lean and respectful of your time:

1. Intro call with a recruiter (30 min)
2. Technical interview with a tech lead — a mix of code and discussion (1h)
3. Team fit conversation with the squad lead, CTO or CEO (45 min)

We aim to move fast. You’ll hear from us at every step.

ChargeGuru / Zeplug is an equal opportunity employer. We welcome applications from all backgrounds and experience levels.
