Tenzir is building an open-core security data pipeline for the AI era. We empower defenders to collect, shape, and route security telemetry at scale. Our stack relies on C++23/26 and Apache Arrow for the core engine, with a modern TypeScript platform layer.
We are hiring for 4 key technical roles to join our distributed team (HQ in Hamburg):
- Software Engineer (Core Engine): Systems programming with C++23/26. Work on our pipeline language, query execution, database integrations, and streaming data processing with Apache Arrow.
- Software Engineer (Product): Full-stack TypeScript/Python focus. Build the control plane, platform APIs, and developer tools, AI workflows, and anything else that makes our engine accessible.
- Account Executive: Our first dedicated AE to own the full enterprise sales cycle. You'll work with complex deals in security and data infrastructure.
- Solutions Engineer: Lead POCs and post-sales implementation. You'll be the hands-on engineer ensuring customers succeed with complex data pipelines.
We are a remote-first team across European timezones. If you like solving hard data problems, we'd love to hear from you.
For deploying Claude Code as agent, Cloudflare is also an interesting option.
I needed a way to run Claude marketplace agents via Discord. Problem: agents can execute code, hit APIs, touch the filesystem—the dangerous stuff. Can't do that in a Worker's 30s timeout.
Solution: Worker handles Discord protocol (signature verification, deferred response) and queues the task. Cloudflare Sandbox picks it up with a 15min timeout and runs claude --agent plugin:agent in an isolated container. Discord threads store history, so everything stays stateless. Hono for routing.
This was surprisingly little glue. And the Cloudflare MCP made it a breeze do debug (instead of headbanging against the dashboard). Still working on getting E2E latency down.
Tenzir is a funded seed-stage startup that builds the next generation data plane for security operations centers. Our mission is to make security operations plug-and-play. Our stack consists of a database and execution engine for security event data, VAST (https://vast.io), for which we are building a Python-based app framework on top.
We are based out of Hamburg, Germany, and hire across EU time zones for engineering roles. For any questions, feel free to reach out to us at [email protected].

Tenzir | DevOps Platform Engineer | FULL-TIME | €70-80k | Hamburg, Germany | http://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 our our ReasonML-based frontend getting its data through a Rust API. We also develop Threat Bus (https://github.com/tenzir/threatbus), a dissemination layer for threat intelligence, which orchestrates detection and response.
=== Role & Responsibilities ===
As a key contributor to our infrastructure, you will improve and automate critical processes for building, packaging, and deploying our technology in test and production environments. Concretely:
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 (GKE, AWS, Azure). 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.
Since I've just switched from buggy Claude Code to pi, I created an extension for it: https://github.com/mavam/pi-mcporter.
There are still a few OAuth quirks, but it works well.
