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)

• Team fit conversation (30 minutes) with our founder and HR

Reference checks and final offer conclude the process.

Application

As part of our initial review, we'd like to understand your technical approach and product thinking. Please share your thoughts on the following:

1. Describe a feature you built that you're proud of. What problem did it solve, and how did users respond to it?
2. What's your approach to designing an API that other developers will use? What makes an API good or bad?
3. You notice users are confused by a feature you built. How do you decide whether to fix the UI, improve the docs, or redesign the feature entirely?

Please submit your answers as a text file or PDF.
