This is a hybrid role based in our Bucharest office (2 days a week in the office)

The role:

A backend infrastructure expert focused on building the core streaming platform, libraries, tools, and developer enablement capabilities.

At Armis, streaming is at the heart of our product. We run hundreds of streaming applications that transform, aggregate, analyze, and enrich the most valuable data we collect from our clients. We process billions of events and petabytes of raw data daily, and this is just the beginning.

Our mission is to streamline the development process for our streaming services and ensure their flawless performance in production. This involves tackling the complex challenges of scalability, latency, and reliability head-on. By developing robust software libraries, enhancing observability, and managing the entire backend infrastructure, our team delivers innovative solutions while optimizing our systems to provide an exceptional streaming experience for our users.

We are seeking a talented and experienced engineer who is passionate about building and optimizing streaming platforms to join our elite team. If you thrive in a fast-paced environment and are eager to tackle complex challenges, we want to hear from you.

  • Improve Infrastructure Observability
    Build internal tooling to improve visibility into streaming pipelines. Create standardized logging, tracing, and metric collection practices.

  • Provide Developer Support and Training
    Mentor developers, document best practices, lead workshops, and provide guidance on how to efficiently and correctly leverage the platform.

  • Support Production System
    Collaborate with DevOps peers to investigate production issues and ensure developer-facing tooling behaves reliably under load.
