Descripción de la vacante

Launchmetrics is seeking a Data Platform Engineer to design and build batch and near-real-time data pipelines using PySpark and Databricks. You will own Bronze/Silver/Gold medallion layers and collaborate with product, QA, and data teams.

This hybrid role supports a Lakehouse powering Discover and internal tooling, emphasizing reliability and cost efficiency while enabling AI-based insights across a fast-paced SaaS environment.

Formación

• Engineer Degree or Master Degree in Computer Science with 3+ years in SaaS data engineering.
• Strong Python and PySpark experience with distributed data processing at scale.
• Experience with a Lakehouse architecture (Databricks, Delta Lake, or Spark on EMR/Glue).
• Knowledge of Bronze/Silver/Gold medallion data design and schema evolution.

Responsabilidades

• Design and build data pipelines (batch and near-real-time) using PySpark and Databricks, across the Bronze/Silver/Gold medallion layers.
• Architect efficient Delta Lake table schemas - partitioning/liquid clustering strategy, schema evolution handling, and enrichment workflows.
• Work closely with product, QA, and other data engineers to translate enrichment and search requirements into reliable pipelines.
• Own code quality: structured PySpark jobs, unit tests (pytest), and adherence to team conventions.
• Continuously improve pipeline reliability and cost efficiency (OPTIMIZE scheduling, retry/backoff logic, concurrency handling).
• Participate in cross-pod initiatives across the data platform.

Descripción del empleo

This role welcomes an hybrid work arrangement,applicants must be based in Spain or France and have a work permit to be considered.

The Team & the Pods organization

We are a team of passionate engineers distributed across the world, always eager to learn new things. We are building state-of-the-art modern applications and scale it on the cloud. We innovate to solve customers problems, focusing on high-performance implementations without neglecting the user experience.

We recently moved our Product and Tech teams to a pod model:

• A pod is a small group, 1 to 4 people, that owns a single mission end to end: from scoping and building through cleaning, enablement and watching adoption. Pods form around a mission and dissolve when it's done. Everyone is a pod owner, from the most junior person to the most senior, because ownership is the point.
• Your domain is your product-area home, the part of our software suite you know best. Pods change with every mission; your craft and your domain don't.

The role

The Data Platform and Data Enrichment teams are in charge of making our unified database accessible, usable, enrichable and reliable for all our teams internally.

The team owns the Lakehouse that powers Launchmetrics' data products — a Databricks-based platform built on Delta Lake, S3, and following a Bronze/Silver/Gold medallion architecture. This layer stores, enriches, and serves the media intelligence data behind Discover (our client-facing platform), Genie (internal tooling), and Delta Sharing. You'll work on a batch-first system that simulates real-time behavior using primitives like Change Data Feed, S3 event triggers, serverless compute, and liquid clustering.

This role plays a key part in our Tech & Product strategy, directly supporting company-wide objectives around customer retention, data trust, and the development of new AI-based insights.

What you'll do

• Design and build data pipelines (batch and near-real-time) using PySpark and Databricks, across the Bronze/Silver/Gold medallion layers
• Architect efficient Delta Lake table schemas - partitioning/liquid clustering strategy, schema evolution handling, and enrichment workflows
• Work closely with product, QA, and other data engineers to translate enrichment and search requirements into reliable pipelines
• Own code quality: structured PySpark jobs, unit tests (pytest), and adherence to team conventions
• Continuously improve pipeline reliability and cost efficiency (OPTIMIZE scheduling, retry/backoff logic, concurrency handling)
• Participate in cross-pod initiatives across the data platform

Technical Stack

• Languages: Python, PySpark, Typescript
• Storage: AWS S3, MySQL
• Cloud: AWS (S3, Kinesis, Lambda, SQS, ECS, Step Functions, …)
• CI/CD: GitHub Actions
• Testing: pytest, Jest

What we're looking for

• Engineer Degree or Master Degree in Computer Science and 3+ years of relevant work experience in full-stack development in a SaaS environment
• Strong Python and PySpark experience; comfort with distributed data processing at scale
• Experience with a Lakehouse architecture (Databricks, Delta Lake, or comparable — e.g. Spark on EMR/Glue)
• Familiarity with medallion architecture patterns (Bronze/Silver/Gold) or similar layered data design
• Ability to reason about schema evolution, partitioning/liquid clustering strategy, and pipeline reliability (retries, idempotency)
• Ability to traverse logical sequences of either procedural or object-oriented code, abstracted or static - and understand it entirely
• Bright, energetic, highly motivated self-starter with experience in a fast-paced, results-oriented organization
• Ability to adapt, estimate workload, break down a task into logical steps, solve problems, self-improve and suggest new ways of improvement
• Last, but definitely not least: you speak, read, and write English fluently

How we hire

• Intro call with Talent Acquisition, to get to know each other (30 min).
• Meet & Greet with VP Software Development.
• Technical Interview, a live interview with a couple of Software Engineers.
• Team fit with the engineers and peers you'd build alongside.
