The Role

We're looking for a software engineer who wants to build things end to end and doesn't mind getting their hands dirty. You'll work across the stack---frontend, backend APIs, and databases---helping us turn ideas into real product and improve what's already in production.

You don't need to have used every tool we use-- what matters is that you have solid full-stack experience, pick up new technologies quickly, and are comfortable owning work without a lot of process or hand-holding. We are still in the early stages of our growth, so if you like autonomy, responsibility, and moving fast, then please apply for this opportunity!

What You'll Do:

• Design and develop web applications using modern frontend frameworks like Svelte

• Build intuitive and user-friendly interfaces that delight users

• Develop and maintain backend APIs using tools like FastAPI

• Manage and optimize database systems like MongoDB

• Collaborate with our ML research team to integrate AI experiences into our products

Who You Are:

• Proficiency in TypeScript or JavaScript

• Experience with frontend frameworks such as React, Vue, or Svelte

• Solid understanding of HTML and CSS

• Hands-on experience building backend APIs

• Knowledge of database systems (SQL or NoSQL; MongoDB is a plus)

Bonus Points If You Have:

• SvelteKit experience

• Python proficiency and AI/ML framework exposure

• Experience in creating AI-driven applications

• Experience deploying and scaling applications on cloud platforms (e.g., AWS, Google Cloud, Azure)

• Familiarity with CI/CD pipelines and DevOps practices to streamline development workflows

• Knowledge of secure coding practices and mitigating vulnerabilities in web applications

• Contributions to open-source projects or an active GitHub/portfolio showcasing relevant work

• Experience with testing frameworks (e.g., Jest, Playwright) to ensure code quality

• Understanding of AI safety principles or ethical considerations in AI systems

If you don't have 100% of these, you should still seriously consider applying. We care more about what you can do than your credentials.

You'll Thrive Here If You:

• You've learned things about your code only production traffic can teach

• You're comfortable debugging across the stack -- from browser devtools to database query plans.

• You've worked in environments where moving fast matters and you know how to balance speed with sustainability.

• You're interested in applying your security mindset to AI, where the threat model is still being written

We offer a competitive compensation package designed to reward impact and incentivize growth. Our compensation philosophy is informed by our current valuation and recent industry data.

Salary: $110k-185k plus performance based bonus

Equity: Competitive equity package
