Your mission
As a Software Engineer (Product) at Tenzir, you build the product experience that makes our powerful security data pipeline usable for real users.
You own product features end-to-end—from technical design through production deployment—working across frontend, APIs, and developer tooling. Your work shapes how security and data engineers interact with pipelines, integrations, and query languages.
You collaborate closely with founders and a small, senior engineering team where your decisions matter. This role is not about implementing tickets; it is about building a product that security professionals actually enjoy using.
Your responsibilities include:
* Build core product features using TypeScript and React, owning the full stack from UI to API
* Design and implement APIs that expose the Tenzir pipeline engine to users and integrations
* Develop integrations with security tools, data platforms, and enterprise systems
* Create developer tooling such as VS Code extensions, CLI workflows, and SDKs
* Improve the TQL editing experience (autocomplete, diagnostics, language server features)
* Own features end-to-end, from design through deployment and iteration
* Shape product direction through technical insight and strong user empathy
* Collaborate with customers when deep product knowledge is required (optional)

Engineering mindset

* You ask “what problem are we actually solving?” before implementing
