Explore your future career 🔭

We're looking for an Data Engineer Intern specializing in data transformation to join Malt's Data Platform team for 6 months, starting September 2026. You'll work closely with a Senior Analytics Engineer who will support and guide you throughout your internship.

This is not a passive internship. You'll contribute to real production work across three tracks: helping research and implement a context layer that makes our data AI-ready, building AI agents that make our data team faster, and tackling legacy table debt that has been slowing us down. You'll also collaborate with product engineers to improve how we instrument and observe our platform because good agents start with good data.

Key responsibilities ✨

Contribute to delivering a context layer for AI-readiness. With guidance from your manager.
Contribute to implementing the context layer strategy. Once the proposal is validated, you'll help implement and test it with AI tools to assess effectiveness.
Help remove legacy tables. Identify unused or outdated tables, coordinate with stakeholders to confirm it's safe to deprecate, and clean them up. Less glamorous, but it directly unblocks the team.
Build and iterate on AI agents within the data engineering codebase (e.g. dbt model generators, SQL reviewers, documentation writers) to reduce repetitive work supported by senior engineers.
Collaborate with engineering, analytics, and business teams.
Document your work: architecture decisions, data model patterns, deprecation rationale, and agent skills so the team can build on it after your internship ends.

About you 🧑‍🚀

High-level education ideally in Computer Science, Data Engineering, or a related field (BAC+4/5); final-year students welcome

You build, not just spec: comfortable writing SQL, building dbt models, and scripting in Python

You can research a problem, form a point of view, and present a structured recommendation not just execute tasks handed to you

You follow AI developments (LLMs, agents, RAG) and have hands-on experience with at least one framework: OpenAI API, LangChain, or similar — you understand why data quality is the foundation of any good AI system

Strong data quality mindset: you know a KPI without a baseline is just a number, and you care about lineage, documentation, and reproducibility

Autonomous and proactive: you flag blockers early and thrive in a fast-moving environment with multiple concurrent projects

Professional working proficiency in English (written and verbal)

How to join the mission? 🚀

Screening call with HR (30 min) to understand your background, motivations, and answer any questions

1st interview with your future manager (60 min)

Homework: a short take-home exercise to present during the 3rd interview

Malt is the perfect space to thrive personally and professionally 💫

- Onboarding: Before easing into your new role, you’ll spend your first week learning about our culture, products, and services with other onboardees at our office in Paris

- Paid vacation - 1 paid day/month worked for interns, 5 weeks/year for apprenticeships

- Lunch vouchers: €9/day on your Swile card

- Transportation: 50% reimbursement (any type of transport)

- Free books: If you’re interested in learning more about any topic relevant to Malt’s business, just tell us the books you’d like to read, and we’ll order them for you—without any questions asked or approval processes to follow.
