Software Engineer

Aethel Defense is an early-stage AI security startup building tools that help companies keep their AI products safe, secure, and trustworthy. The Software Engineer will own full-stack features across TypeScript, Node.js, PostgreSQL, React, cloud deployment, and automated testing while helping shape the product and engineering culture.

Responsibilities:

• Build and ship full-stack features in TypeScript across our API, database, and web app
• Design and evolve PostgreSQL schemas and the data layer behind the product
• Build clean, fast, usable interfaces in React
• Deploy to a modern cloud stack and keep CI/CD healthy
• Write the automated tests that let us move fast without breaking what matters
• Help shape the product and the engineering culture as one of the first hires

Requirements:

• A portfolio, a GitHub, shipped side projects, open-source work, a CTF record, something you've put in front of real users
• No degree or years-of-experience requirement
• Real fluency in TypeScript / JavaScript and Node.js, and strong engineering fundamentals
• Backend comfort: REST APIs, relational databases (PostgreSQL), SQL, data modeling
• Front-end skill with React (ideally Next.js)
• A security mindset: you think about what can go wrong, and you test for it
• Self-direction. You do your best work with ownership, not a backlog someone else grooms for you
• Interest or experience in AI / LLM applications
• Background in cybersecurity or application security
• Experience with cloud platforms, serverless, or CI/CD pipelines
• You've shipped something end to end that you can prove
