Monadical Careers (on behalf of Greyhaven): Software Engineering Intern

Who We Are

Greyhaven builds the last mile of AI systems that run inside our clients’ infrastructure. We take workflows end to end, then design the application layer around it, so AI actually gets used in a safe and sovereign way. We’re committed to data sovereignty and privacy: our systems often stay on-premises and the client keeps control of their data. Our flagship product, Greywall, is a kernel-level visibility and control layer for AI coding agents.

We’re a relatively flat organization, fully-remote, and operate across many different toolsets and stacks depending on project needs. We’re a diverse team that shares similar values: self-direction, technical excellence, and curiosity. We do a lot of R&D;, and move quickly. That often means doing whatever it takes to answer a question, and being quick to adapt to current information. Our iteration cycles are short.

The Internship

This is 4-8 month, paid, internship starting ASAP (or in early January). You’ll join a real project team and ship code that goes into production for clients. You won’t be put on a side project that never sees the light of day.

With support from a senior development team, you’ll:

- Build features across the stack, mostly in Python, TypeScript, and React
- Help build and test LLM-powered applications, including retrieval, agents, and evaluation
- Help deploy software into self-hosted and on-premises environments
- Learn how client projects run, from requirements to delivery

What We’re Looking For

You don’t need you to know everything. We care more about how you learn than what you already know. We’re looking for someone who is curious, picks things up quickly,



and isn’t afraid to ask questions. You’ve built things on your own, whether for school, side projects, hackathons, or open source, and you can explain how they work and why you made the choices you did.

We work fully remotely, so you should be comfortable managing your own time and speaking up when you’re stuck. You won’t be doing it alone: we’re active on chat and calls, and we check in regularly.

- Currently enrolled in, or recently graduated from, a computer science, software engineering, or related program
- Some experience building web applications (React is a plus)
- Comfortable with Git and the command line
- Available during Eastern working hours (9 a.m. to 5 p.m. ET, flexible)

Nice-to-have

- Projects that use LLM APIs or open-weight models
- Some experience with Docker or Linux
- Interest in security, privacy, or systems programming
- Open-source contributions

The Perks

Working with us comes with perks that matter:

- Paid internship
- Fully remote, anywhere in Canada
- Flexible hours
- Mentorship from senior developers, with regular code reviews
- Real work on AI systems in production

How We Hire

- Short Coding Test: Complete our coding test through this application process.
- Conversational Interview (30 to 45 mins): A conversation with an internal team member about you, your projects, and what you want to learn.
- Short take-home project: A small, well-scoped task. Shouldn’t take any longer than 2 hours.
- Pairing Interview (60 min): Add a feature to your take-home project with a developer. We care about how you think and communicate, not whether you finish.

The whole process usually takes 2 weeks depending on the applicant pipeline and response times.
