Software Engineer, Frontend

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

 

We're a growing team of engineers, operators and technicians from companies like Palantir, Qualcomm, Dyson, Shopify, Tesla, Meta and Google DeepMind. It's still the early days of building the company, and this is a chance to make an outsized impact on a problem that matters. From day one, you’ll be working with an experienced founding team, backed by a $32M Series B led by Khosla Ventures and Plural.

 

Monumental is based in the city centre of Amsterdam, in a beautiful facility with an fully equipped workshop and robot testing floor. We build the whole stack in-house - hardware and software, we're explicitly not a hybrid or remote-first company - you can't build robots or walls from home, so we're onsite five days a week.

About the role

At Monumental we’re automating on-site construction with robotics and software. Atrium, our operating system for construction, lets us do everything from designing the 3D structures we'll build, to managing our robot fleet, planning operations, and analyzing data.

 

As we scale our operations and manufacture, deploy, and maintain more robots, the scope of our software keeps growing. We're now building internal apps for scheduling robot operators, planning site logistics and maintenance, and improving manufacturing. We're looking for a frontend engineer to help us build more and better internal tools, and to move manual processes into software.

 

You won't just be handed requirements. You'll talk to the people who'll use what you build (your colleagues), work out what's actually worth building, implement it, deploy it, and check whether it helped. If you enjoy building software products start to finish on your own, this role is a good fit. You'll get a lot of autonomy and the chance to build software that builds actual robots and houses. For more on how we think about the role, read Tobias’ post on why now is a great time to be a product engineer at Monumental.

 

What you'll do

• Taking a problem from a colleague and understanding it, building a prototype, getting it in their hands, and iterating on the solution - often all in the same day.

• Designing and building tools to manage a growing fleet of robots spread across multiple sites.

• Extending Fenestra, our Notion-like internal tool for viewing and editing data from different sources.

• Helping bring prototypes from the ops and manufacturing teams to production, cleaning up the data model and code along the way.

• Working with hardware engineers, control engineers, and robot operators to find the best product experience for genuinely hard problems.

• Writing clean, idiomatic, typed production TypeScript and React. We also use Rust in places.

• Debugging memory leaks, crashes, and other problems, often by digging into the root cause yourself.

• Deploying and maintaining 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 in building products in a zero-to-one environment, on your own or in a small team. This can be a side-project you’ve worked on, an indie app, or some other project you can show us.

• 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. E.g., you’re comfortable ssh’ing into other machines to figure out why something isn't working.
