About the role

About us: Aethel Defense is an early-stage AI security startup. We build the tools companies rely on to keep their AI products safe, secure, and trustworthy. We're small, moving fast toward our first customers, and looking for an engineer who wants real ownership from day one. New grad, self-taught, or ten years in, we don't care about the badge. We care about what you can build and whether you can prove it.

The role: As a Software Engineer, you'll work across the whole stack: a TypeScript and Node.js backend, a PostgreSQL data layer, a modern cloud deployment, and the React web app our customers use. You won't be handed narrow tickets. You'll own features end to end, from database to UI, and your code will reach production fast. This is a high-trust, remote-first role. You're comfortable making decisions, writing your own tests, and caring about quality and security, because that's the business, we're in.

What you'll do:

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 ReactDeploy 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

What we're looking for:

Proof you can build. A portfolio, a GitHub, shipped side projects, open-source work, a CTF record, something you've put in front of real users. Evidence over credentials. 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 itSelf-direction. You do your best work with ownership, not a backlog someone else grooms for you

Nice to have:

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
Compensation & logistics$80,000 to $120,000 base depending on skill, plus meaningful early-stage equity
Fully remote, full-time
Direct work with the team, genuine ownership, and a front-row seat as we grow

Background CheckAll selected candidates go through rigorous background screening prior to employment due to sensitivity of work.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
