Help Build a Generational Company

At Knowlix
, we’re on a mission to 10x small businesses' productivity. We strive to become the dominant small business platform for human-AI and AI-to-AI collaboration.

We’re still early, but we’re thinking big. This is your opportunity to help shape a product that serves millions and defines a category.

We move fast, ship often, and obsess over quality. If you burn to build, ship, and scale - and you love using AI to make things radically better - this is your seat at the table.

• Our tech works - and first users are already feeling the first magic
• We're going after a massive market, with a product that changes how people work
• You’ll be joining as one of the earliest team members - with real influence and ownership over the trajectory of the company
• We believe speed is a function of focus + iteration

This isn’t a job. It’s a chance to help build a once-in-a-generation company if we do things right.

We’re looking for a pragmatic and passionate Backend Engineer with strong backend skills in Python and a solid grasp of SQL and cloud infrastructure
. You’ll work closely with AI researchers, product designers, and Dev Ops engineers to build a seamless bridge between human users and our AI agents. Interest in Go

• 5+ years of experience in fullstack or backend-focused software development
• Proficiency in Python and experience with modern Python web frameworks
• Good command of SQL and working knowledge of relational databases (Postgre
  
  SQL, MySQL, etc.)
• Experience with AWS

• Familiarity with JavaScript and front-end technologies (React, Vue, or similar)
• Curiosity and willingness to learn Go or Swift
• Strong communication skills and comfort working in a startup environment

• Experience building or integrating with LLMs, vector stores, or AI inference pipelines

• Background in data processing, message queues, or streaming architectures
• Exposure to mobile app development or cross-platform environments (e.g., Swift
  
  UI)
• Experience with RPA tools and workflows
• Familiarity with Graph APIs

• A path-defining role in a high-upside company backed by world-class investors
• Deep ownership and equity
