Site Reliability Engineers (SRE) at PayLead are both systems and security engineers that ensure we can reliably and securely serve our clients (banks, insurances, fintech, retailers). As we operate multiple services (API, front-ends) for our clients, and within a complex regulatory and competitive framework, you’ll keep learning new things everyday and share what you have learned with the team.

The platform we develop uses bare-metal systems running on providers LeaseWeb and OVH. Since our infrastructure is a critical component of many applications, the SRE team maintains a high level of expertise in system failures in order to prevent them and provide reliable service to our customers.

The team is composed of engineers with different backgrounds and experiences both in the industry and academia. We expect you to bring your curiosity, your eagerness to learn, and your passion for excellence and quality!
