Tenzir | C++, ReasonML, Rust, Python | Hamburg, Germany or Remote (EU timezones) | Open-source | Full-time | https://tenzir.com

Tenzir is an early-stage startup that builds a next generation data-plane for modern Security Operations Centers. It is our mission to help defenders pull ahead by integrating widely used open source tools and building solutions that reduce the time to detect attacks and help with post-mortem investigations. To that end, we develop the high-performance C++ database [VAST](https://github.com/tenzir/vast) with a ReasonML-based frontend that is served by a Rust API. We also develop [Threat Bus](https://github.com/tenzir/threatbus), a dissemination layer for threat intelligence, which orchestrates detection and response products in a publish/subscribe architecture.

Tenzir | Hamburg, Germany| DevOps Platform Engineer | FULL-TIME | REMOTE | €70-80k | https://tenzir.com

Tenzir is seeking an experienced and passionate DevOps / Platform engineer who enjoys bringing open-core security technology into production deployment shape. We cultivate a UNIX-centric mindset: security operators use our high-performance C++ database VAST (https://github.com/tenzir/vast) to hunt in telemetry data, either via the CLI or our ReasonML-based frontend getting its data through a Rust API.

We also develop Threat Bus (https://github.com/tenzir/threatbus), a messaging layer for federating security content.

=== Role & Responsibilities ===

- Improve our CI/CD pipelines for continuous releases with GitHub Actions to build projects of different languages on various platforms and to automate unit and integration testing.

- Automate continuous deployment strategies in different environments, for our own staging and production clusters, but also on-prem (appliances) or with different cloud providers.

- Implement a reliable backend infrastructure for appliance and fleet management, configuration management and multi-layer VPNs.

- Write integrations with other tools from the (security) ecosystem to support a wider range of data formats.

- Be responsible for entire infrastructure segments, from whiteboard design to implementation and automation for production systems.

=== Interview Process ===

1. Fill out the application form at https://tenzir.com/career/devops-platform-engineer/

2. Phone call to get to know each other and identify potential roadblocks (30min)

3. Technical interview(s) (1-2h)

I am myself studying it and going through the official documentation and toying with k8s flavors like kind, k3s and k0s.

There's a whole community of hobbyists building Raspberry Pi clusters, porting things to work on various Arm processors, exploring and contributing to minimalist distros like k0s and microk8s, etc.

I use k0s btw ,and it is fantastic.

Here is link number 1 - Previous text "k0s"

So for example, in my own personal infra repos and for projects I do, Make orchestrates Pulumi, dnscontrol (Holy shit is that tool underrated), ansible, k0s/k0sctl (I run that distro), and all the kubernetes stuff.

I wasn’t able to run Kubernetes in NAS last time I tried it. https://github.com/k0sproject/k0s/issues/1184. As for public access you don’t want to do it for security reasons and instead rely on vpn. Tailscale and ZeroTier are easy to setup.

I prefer k0s, https://k0sproject.io/ .

actually that is not really true - i strongly urge you to try out http://k3s.io/ or https://k0sproject.io/

these are full-fledged, certified k8s distributions that run on raspberry pi as well as all the way in production.
