MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.

We're looking for experienced FULL-STACK ENGINEERS who can help us solve problems like:

- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)

- Rapid deployment and iteration of experimental software changes across firmware, control software and UI

- Modelling buildings in code and finding the right UI for operators to edit them

Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium

We're rapidly scaling up operations and we need experienced, generalist engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

CourtDrive | Principal AI Engineer | REMOTE| Market | Full-time | https://www.courtdrive.com/

At CourtDrive.com, we are building an AI Docketing Assistant that enables law firms and other power courthouse website users to become more efficient by automating daily tasks. We’re based in Los Angeles but have a remote team worldwide (Canada, Europe, Armenia to name a few). Your role as Principal AI Engineer will be to lead CourtDrive's AI strategy through model evaluation, fine-tuning, and data collection. You'll work alongside our engineering team to bring AI features from concept to production, while elevating the team's understanding of language model capabilities and best practices. Your expertise will be crucial in determining how we can best leverage AI to enhance our solution.

This role offers a unique opportunity to apply deep language model experience in a product focused on transforming how law firms practice the business of law.

Testimonial from a team member: “Long story, but I worked there for maybe 6ish months part time a while back. They offered me full time, but I ended up going to a startup because I wanted to learn some specific technologies + up my skills in Data Science. That job was definitely good for some people, but it wasn’t as remote as they advertised it (had me fly in a lot), and the team was somewhat difficult to work with ;) I ended up starting my own consulting and at the same time CourtDrive reached back out to me (perfect timing). Point I was trying to make was that I went back to work with them because they were so nice to work with. Not super demanding and very open to listening to ideas/suggestions - just a pleasant environment.”
