Senior Fullstack Software Engineer

Full-time | Munich | Seed Stage | Equity + Salary

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.

Why Knowlix, Why Now
We're a well-funded seed-stage startup, backed by top-tier investors and experienced founders.
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.

The Role
We’re looking for a pragmatic and passionate Fullstack 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 DevOps engineers to build a seamless bridge between human users and our AI agents. Interest in Go and Swift is a plus, especially for future product components like microservices or mobile interfaces.

What You Bring (Requirements)

• 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 (PostgreSQL, MySQL, etc.).
• Experience with AWS, Docker, and basic DevOps workflows.
• 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.

You’ll Thrive Here If You… (Preferred)

• Experience building or integrating with LLMs, vector stores, or AI inference pipelines.
• Knowledge of microservices, gRPC, or real-time systems.
• Background in data processing, message queues, or streaming architectures.
• Exposure to mobile app development or cross-platform environments (e.g., SwiftUI).
• Experience with RPA tools and workflows.
• Familiarity with Graph APIs.

What You’ll Get
A path-defining role in a high-upside company backed by world-class investors.
Deep ownership and equity.
A team that cares deeply about what we’re building and the people we build it with.
A rare chance to leave your mark on something that has the opportunity to become generational.
