Senior Platform Engineer (gn)

Location: All Hubs (Frankfurt, Stuttgart, Berlin)

As part of the Boerse Stuttgart Group, Boerse Stuttgart Digital has built the largest digital and crypto business of all European exchange groups. With solutions for institutional clients in the areas of brokerage, trading, and custody, as well as the BISON platform for retail investors, Boerse Stuttgart Digital provides reliable, regulated, and transparent access to the world of cryptocurrencies. The Boerse Stuttgart Group employs more than 700 people across locations in Stuttgart, Berlin, Frankfurt, Stockholm, Zurich, Madrid, Milan, and Ljubljana.

Within Platform Engineering, we provide the reliable and scalable foundation on which our product and engineering teams build. Boerse Stuttgart Digital operates institutional and retail brokerage, the BSDEX crypto exchange, and its own in-house custody solution – all within the governance framework of a leading exchange group. Having recently launched our Internal Developer Platform, we are now looking to establish it as a trusted production platform across Boerse Stuttgart Digital. As Senior Platform Engineer (gn), you will operate and further develop the platform, introduce platform engineering and SRE practices, harmonize our toolchain, and replace ad-hoc operations with reliable, automated, and well-documented processes. You will take hands-on responsibility for critical systems while helping us raise our engineering standards for the future.

Ready to shape the technological foundation of regulated digital asset infrastructure in Europe? Bring your platform engineering, SRE, and automation expertise to our team and help us build secure, reliable, and scalable ways of working. We look forward to your application!

Your Tasks

• Platform Operations: Run our production IDP and the services on it, owning reliability, availability, and performance in a regulated crypto environment.
• SRE Practices: Introduce SRE principles such as SLOs, observability, incident response, and blameless post-mortems, and cut manual toil through automation.
• Toolchain Harmonisation: Consolidate and standardize our toolchain so teams have clear, paved paths instead of one-off solutions.
• Engineering Excellence: Help move the team from unstructured operations to documented, repeatable engineering, and mentor colleagues along the way.
• Data Layer Operations: Keep our databases (MS SQL Server on Linux and PostgreSQL) reliable, performant, and recoverable.
• Secure Modernisation: Support our on-premise to AWS journey and apply security hardening and audit-ready documentation expected under DORA and MaRisk.

What You Bring to the Table

• Platform & SRE Experience: Several years of hands-on experience operating a developer platform or production infrastructure at scale, with a proven ability to bring reliability and structure to production environments.
• Regulated Environments: Experience in financial services or another regulated, high-availability environment, ideally with exposure to DORA and MaRisk.
• Linux Foundation: Deep, hands-on Linux expertise from the CLI, including internals, systemd, hardening, and troubleshooting. LPIC-2/3, RHCE/RHCSA, LFCS/LFCE, or equivalent experience is highly desirable.
• Automation & Containers: Fluent scripting in Bash and/or Python, combined with solid hands-on experience with Docker and Kubernetes.
• Security Mindset: A security-first approach to everything you build and operate; comfort with hardening standards such as CIS.
• Language Skills: Excellent English skills, both written and spoken; fluent German is a strong plus.

Beyond this core profile, strengths in one or more technical areas are welcome. You do not need to cover all of them — tell us where your expertise is strongest:

• Databases: Experience operating MS SQL Server on Linux and/or PostgreSQL 13+ in production environments, with a focus on high availability, backup and recovery, performance tuning, replication, and failover.
• Cloud & Migration: On-premise to AWS migrations and infrastructure as code with Terraform.
• Platform Toolchain: Operating tools such as Tyk, Keycloak, SaltStack, HAProxy, Rancher, Argo CD, and Prometheus, with strong monitoring and alerting.
• Infrastructure & Networking: Experience with vCenter and NSX-T, Okta administration, data-centre capacity management, and VPN and inter-site networking.

What We Offer You

• Dynamic and Innovative Environment: Work in the midst of a dynamic, fast-growing, and innovative sector of Crypto & Digital Assets
• Room to Shape: A responsible role in which you can actively develop our Internal Developer Platform and further improve our platform engineering processes
• Attractive Compensation: Competitive remuneration that rewards success and performance
• Modern Hybrid Work Environment: Hybrid work opportunities in Stuttgart, Berlin, or Frankfurt with flexible working hours
• Additional Benefits: Perks such as bike leasing, subsidy for Urban Sports Club or Wellpass, Workflex with up to 20 days per year working in a European country of your choice, and 30 days of vacation, plus extra days off on December 24th and 31st
