About osapiens

At osapiens, more than 550 talented minds unite around one mission: enabling sustainable growth for businesses worldwide. Founded in 2018 and headquartered in Mannheim, Germany, we have built the AI‑driven osapiens HUB – a multi‑tenant platform hosting 26 enterprise‑grade solutions designed for cross‑company collaboration, automation, and compliance. With offices across Europe and the US, we are shaping the future of scalable and secure business technology.

Your Team

Our System Administration & Operations Team (Hybrid in Mannheim – 3 days/week on site) keeps the osapiens technology platform running smoothly, securely, and at scale. They manage and optimize Linux servers, ensure stability, automate operational workflows, design high‑availability architectures, and push performance monitoring and troubleshooting to the next level.

Your Key Responsibilities

• Manage infrastructure & databases: optimize Linux servers in public cloud environments while operating and improving distributed database systems (e.g., ScyllaDB, Cassandra, Elasticsearch/OpenSearch). Ensure high availability, reliability, and performance across both compute and data layers.
• Proactive monitoring & performance optimization: continuously monitor system and database performance, identify bottlenecks, and implement tuning measures across distributed data clusters and Linux environments.
• Troubleshoot distributed systems: diagnose and resolve complex issues within distributed databases, Linux servers, and cloud infrastructure—ensuring stable, scalable, and resilient operations.
• Automate with IaC: increase efficiency through Infrastructure‑as‑Code using tools like Ansible, automating database operations, cluster provisioning, and configuration management.
• Collaborate across teams: work closely with cross‑functional teams to optimize, scale, and evolve infrastructure and database systems for internal services and customer‑facing platforms.
• Guide & support: provide expert guidance to colleagues and customers on database best practices, system performance, and scalable architecture patterns—ensuring smooth cloud and data operations internationally.

Your Experience

• Passion for Linux, automation & databases: enthusiasm for Linux, open‑source technologies, distributed databases, and automation‑driven infrastructure.
• Strong Linux & DB expertise: extensive experience managing Linux (Ubuntu) systems as well as operating SQL/NoSQL databases in distributed environments. Experience with ScyllaDB, Cassandra, and/or Elasticsearch/OpenSearch is highly desirable.
• Monitoring & optimization skills: hands‑on experience with monitoring and performance tooling such as Grafana, Prometheus, and Bash scripting. Ability to analyze database and system metrics to drive improvements.
• Distributed systems know‑how: understanding of replication, sharding, consistency levels, failover strategies, and capacity planning for distributed data platforms.
• Networking & security proficiency: solid understanding of networking and security principles (firewalls, load balancing, TLS, performance tuning).
• DevOps knowledge: familiarity with the DevOps lifecycle and IaC tools (Ansible, puppet, chef, etc.) is a plus—especially for automating database & deployment lifecycle tasks.
