DevOps / Platform Engineer

Berlin, Germany (Remote work possible within Germany)

About us:

CALIMA is a Berlin-based B2B SaaS startup with a mission to make workplace safety simpler, more reliable, and more effective through digital and innovative solutions. Our software helps companies ensure that lone workers receive assistance quickly in an emergency. CALIMA is used by hundreds of companies and protects thousands of employees every day. We are a small, ambitious team with high standards of quality, and we work pragmatically and with a focus on the product. We are looking for people who don’t just check off tasks, but who take responsibility, contribute ideas, and actively improve our processes.

Your role:

As a DevOps / Platform Engineer, you play a key role in ensuring the stability, security, and scalability of our entire platform. You will be responsible for the infrastructure of a security-critical product that protects thousands of remote workers every day. In this role, you will ensure that our systems run robustly, perform well, and remain highly available.

Quality is our top priority at CALIMA: We rely on EU-based providers (OVH and Hetzner) and operate a multi-cloud setup to ensure reliability, data sovereignty, and cost control—with a focus on EU hosting and data protection.

Important: We are a small tech team. For you, this means a lot of ownership, creative freedom, and direct impact—but also a willingness to take on projects from start to finish. We’re looking for someone with high standards who proactively identifies, prioritizes, and implements solutions—from architectural decisions to operational excellence. You’ll start by working closely with the Head of Tech and will quickly take on a lot of ownership.

• Experience with highly available, mission-critical systems —ideally in a B2B SaaS or security-related context
• A structured, self-directed, and quality-conscious approach to work , combined with a pragmatic understanding of priorities (features vs. stability vs. technical debt)
