About Us

Do you want to take ownership from day one and actively shape the future in a growing company? VoiceLine is a fast-growing, VC-backed startup based in Munich. We build an AI-powered solution that helps field sales and service teams turn conversations into structured data efficiently. This enables customer information to be documented, analyzed, and seamlessly integrated into existing systems. Together with leading enterprise customers, we are working to make field sales future ready.

The Role

Your Mission

As an Infrastructure & Security Engineer at VoiceLine, you will own the infrastructure our product runs on and the security posture around it. Over the coming months we are making substantial changes to how and where our platform operates, and you will be the person shaping those architectural decisions and implementing them. You will work in a small, senior setup: directly with our CTO and with the engineer who currently owns our infrastructure and security. You will also work close to our customers, since some of Europe's largest industrial companies run their field sales on our platform and their security and deployment requirements land on your desk directly.
This is not a ticket-driven ops role.
 Routine operational toil is increasingly handled by automation and AI agents. We are hiring for judgment: architecture, security standards, and the ability to implement them yourself rather than hand them off.

Your Tasks

• Own and evolve our AWS infrastructure, including a significant set of platform changes planned for the months ahead
• Define our security standards and own them end to end, covering access and identity, network security, vulnerability and dependency management, controls, audit and certification readiness
• Make the architectural calls on how our platform is operated, deployed and scaled, including how portable and provider-independent it needs to be and how much of our stack we run ourselves
• Work directly with our CTO and our existing infrastructure and security engineer on technical direction, and split ownership of the platform between you
• Implement customer-specific infrastructure and security setups together with our Delivery team, from SSO and network access to isolation and data-residency requirements
• Build and maintain infrastructure as code, CI/CD and observability so engineers ship fast without waiting on you
• Act as our technical counterpart for enterprise security reviews, questionnaires and penetration tests

Your Profile

• Minimum 2 years of hands-on, full-time infrastructure experience. Two to five years is our sweet spot, and more is very welcome
• Deep AWS experience, since our entire platform runs on it. This one is non-negotiable
• Strong command of infrastructure as code, containerized workloads and CI/CD pipelines
• Solid security fundamentals: identity and access management, network security, secrets handling, and working with compliance frameworks in practice
• You do not have to be a full-time software engineer, but you do not back away from writing and shipping code when the task calls for it
• You find it interesting rather than alarming that our infrastructure will not look the same in twelve months as it does today
• Excellent written and spoken English; German is a plus
• Have other skills and/or experience not listed here? Tell us what you're especially proud of (work-related or private) in your cover letter

Benefits

• A dynamic environment with flexible working hours and a strong team culture
• Competitive and fair compensation package, including virtual equity participation
• Modern office in the heart of Munich and a hybrid working environment (depending on the role)
• Access to Wellpass and attractive sports and wellness offerings to support your well being
• Support for public transport (Deutschlandticket)
