Software Engineer - Core Services (All Genders)

Hey!

Imagine amateur football finally had the platform it deserves. Every weekend, millions of people write their own personal football stories – on pitches, in clubs and on the sidelines. We believe this passion deserves a digital home too. That's exactly what we're building every single day.

tl;dr

We’re looking for someone who keeps our football data right: results, stats and market values players can trust, especially right after the final whistle.

Main information

• Start:  Immediately
• Location:  Office Cologne, Berlin, London or remote
• Type:  Full-time
• Team:  Core Systems

Is this a match?

The basics - so we both know if it could work.

• Flexible: Hybrid from Cologne, Berlin or London, or remote within the EU or UK - we'll find the mix that works for you.
• 5+ years in: You've been a software engineer with a data focus for 5+ years, still write production code yourself and have owned a pipeline or dataset in production end to end.
• Self-starter: Drop you into a codebase with years of history and you'll find your way - reading the code, the data and the git log yourself, and asking "why does it look like this?" before you change it.
• Agent-native: We build with Claude Code every day. Whichever coding agent you've used so far, you plan with it, review every line it writes, and own what ships.
• Small steps, shipped often: Tests first, small merge requests, a teammate reviews - then it's live. That's our rhythm.
• Football-curious: You don't need to know everything about grassroots football yet - but you want to understand how it works, inside out.
• English first: It's our working language. We're an international team, though, so you'll also hear German, Spanish, Dutch and more around the (virtual) office.

What you'll do - your playing field

This is how you move our mission forward every day.

• You keep our football data right. Results, lineups, goals, appearances, stats and market values: you make sure what reaches the app matches what happened on the pitch - and what our users tell us happened there.
• You build and run data processing services. Python services and pipelines that turn match data from many sources into the teams, players and stats in our app - tested, monitored and ready for the weekend peak.
• You make data quality measurable. Validation, monitoring and alerts - and when something's off, you fix the root cause, not just the symptom.
• You become one of our football data experts. Age groups, season changes, renamed and merged teams, duplicate players, players who remember the match differently - you learn how grassroots football data really behaves and turn that knowledge into rules our systems enforce.
• You think about the player at the end of the pipeline. A missing goal or a wrong appearance is someone's weekend. You care how data shows up for players and clubs, not only whether the job ran.

In addition to your core responsibilities, you will also:

• Shape how our data models evolve, together with the engineers who own data acquisition and processing
• Support our data and business colleagues on the technical side of data requests - the queries, data pulls and checks behind analyses for internal teams and partners
• Build small internal tools so our support and product colleagues can check and fix data themselves

What you bring to the team

We're not looking for a perfect CV. But you should recognise yourself in these points.

• Data pipelines: You've built and run production data pipelines that others relied on.
• Python: You've shipped Python services with tests and code review.
• SQL & data modelling: You're strong in SQL and model data cleanly on PostgreSQL or similar.
• Data quality: You've owned the quality of a dataset - with checks, monitoring and gaps made explicit.
• Messy data: You've made data you don't control reliable - inconsistent names, duplicates, late corrections and all.
• Communication: You explain a data problem clearly to people who don't write SQL.
• Tools: Python, PostgreSQL, RabbitMQ, AWS, Kubernetes, GitLab CI, Grafana, Metabase, Claude Code

Good to know
We want you to know what this role really looks like from day one.

• This is a software engineering role with a data focus: you write Python services and pipelines, not only SQL models and DAGs. Most of your time goes into getting football data right and keeping it that way.
• You join Core Systems, where backend and data work as one team. You'll take over an existing domain with a lot of history, so you'll be working on your own fairly quickly - with the team there to explain the why.

Bonus

Not a must - but this'll definitely earn you extra points.

• You've built ingestion pipelines from external sources like club homepages - and kept them running when those sources changed
• You have a football background: you've played, coached or helped run a club
• You've built dashboards or reports for non-technical users
• You've worked with a mobile or frontend …
