Software Engineer (Product)

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 care about how your code feels to use, not just whether it works
