Lead Performance Engineer - Tech Platform

Permanent employee, Full-time · Dublin

The Role
At Personio we are on the amazing journey of scaling to meet our exponential growth in customers. After our recent $125M Series D funding we are the most valuable HR tech company in Europe and our company goal is to be the leading HR Platform for SMEs in Europe.

We are investing heavily in our Technology Platform team and their mission is to ensure Personio builds and scales as a high performing engineering organisation. We drive initiatives that enable our product engineering teams to build, test, deliver and operate the Personio application software to the highest industry standards.

We are creating a new Performance Engineering team which will play a key role ensuring our platform scales to accommodate our 2023 load and beyond. We are looking for a Lead Engineer to set the technical foundations for this team and help to mentor other team members as they come aboard.

As a Lead Performance Engineer you will be designing frameworks and tools to automate testing of performance on our platform. You will create tests to push our system to its limits to find issues for future customer workloads. The performance testing stack will be your responsibility to create, maintain and update with data which realistically reflects the projected customer data profile for 2+ years in advance. Your job will be to ensure that our performance tests are valid, and the schedule automatically runs or can easily be run on demand. The outputs of each performance run will be an automated report or scorecard which can be easily interpreted by product teams and will automatically notify the right team for their attention. Later we will shift left on performance as part of the build and deploy process, introducing a ‘performance gate’ into our CI/CD system.
