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

• Data Platform: Databricks, Delta Lake, Delta Sharing

• Storage: AWS S3, MySQL

• Cloud: AWS (S3, Kinesis, Lambda, SQS, ECS, Step Functions, …)

• Tools: Jira, Databricks Asset Bundles, Serverless, Claude Code

• Versioning: Git, GitHub

• 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/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.

Why you'll love it here

We're a company that puts people first, with a relaxed but genuinely dynamic atmosphere and a team of motivated, curious people who like their work. Autonomy is real here: pods make local decisions and own their outcomes, which means you'll see your fingerprints on the product quickly.

You'll get a learning and development allowance, a benefits package tailored to your location, flexible working arrangements with support to set up your home office, and the room to grow along whichever path fits you. We're remote-friendly, with hubs across our twelve markets.
