Software Engineer, Product

Monumental is automating on-site construction with robotics and software. Its mission is to make construction software-defined and autonomous - a future where beautiful, bespoke buildings go up in a single day, with minimal labour.

Monumental builds the whole stack in-house - hardware and software - and is based onsite in Amsterdam five days a week.

About the role

At Monumental, Atrium, its operating system for construction, supports everything from designing the 3D structures to be built, to managing the robot fleet, planning operations, and analyzing data.

As operations scale and more robots are manufactured, deployed, and maintained, the scope of the software keeps growing. The team is building internal apps for scheduling robot operators, planning site logistics and maintenance, and improving manufacturing. The role is for a product engineer to help build better internal tools and move manual processes into software.

Product engineering at Monumental means not just receiving requirements, but talking to the people who will use what you build, figuring out what is worth building, implementing it, deploying it, and checking whether it helped. This role offers autonomy and the chance to build software that supports real robots and houses.

What you'll do

• Take a problem from a colleague, understand it, build a prototype, get it into their hands, and iterate on the solution - often all in the same day.
• Design and build tools to manage a growing fleet of robots spread across multiple sites.
• Extend Fenestra, the internal tool for viewing and editing data from different sources.
• Help bring prototypes from the ops and manufacturing teams to production, cleaning up the data model and code along the way.
• Work with hardware engineers, control engineers, and robot operators to find the best product experience for genuinely hard problems.
• Write clean, idiomatic, typed production TypeScript and React. Rust is also used in places.
• Debug memory leaks, crashes, and other problems, often by digging into the root cause yourself.
• Deploy and maintain new backend services your tools need.

What we’re looking for

• You’ve built full-featured web apps in idiomatic TypeScript and shipped them. React experience is a plus.
• Proven experience building products in a zero-to-one environment, on your own or in a small team. This can include a side project, an indie app, or another project you can demonstrate.
• An eye for good design, both UI and UX.
• A strong sense of ownership. You can drive a project from start to finish without anyone managing you, and you're comfortable when things are chaotic.
• You use coding agents to ship faster and unblock yourself but take full ownership of the features you build with AI.
• You pick up new languages and tools quickly. Rust experience is a plus.
• Basic familiarity with Linux systems. For example, you’re comfortable ssh’ing into other machines to figure out why something isn't working.

Why Monumental?

Joining Monumental means working on complex challenges in construction robotics with the opportunity to make a tangible impact on how buildings are made.

Monumental does not currently support internships.

If you don’t meet all the qualifications but are excited about Monumental and feel you could still help solve difficult problems, generalists who focus on outcomes and are eager to learn on the job are welcome.
