Assembly & Prototyping Technician
Confirmed on the employer's own hiring board on Nov 2, 2026. First seen by Alion on Jun 10, 2026. Monumental scores C on the Alion truth index.
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
We are looking for an assembly & prototyping technician to join our team. You’ll be part of our machine shop team, and working closely with our hardware and software engineering team.
This role is a generalist technician role in a small startup environment with a lot of variety. You will be responsible for assembling small production series and occasionally building prototypes of our construction robot hardware, including our autonomous ground vehicles, construction cranes, supply systems, and end effectors. You will also be helping out with the maintenance of our existing fleet of robots. After doing an assembly, you actively ask yourself how you could do it 10 times faster if you had to do it over again.
We are unable to support relocation or sponsorship for this role. Applicants must be based in the Netherlands, eligible to work and able to commute onsite to Amsterdam to be considered.
What you’ll do
Fabrication and assembly of production hardware and maintenance of our existing fleet - this could be anything from end-effectors and autonomous ground vehicles that can traverse rough construction sites, to entire robotic cranes.
Maintaining our current fleet of robots: doing occasional health checks on them and ensuring that they are always in great state and ready to be used on site.
Help us run our construction robots and build testing rigs in the office, and occasionally join us and the robots on construction sites to help with whatever is needed.
Help us improve our designs to small series production: planning and organizing a build, feeding back DFM and DFA changes to the engineering team, and assembling the robots.
Promoting and maintaining a safe, clean, and organized working environment.
What we’re looking for
You must feel comfortable in sequencing and building assemblies without a large amount of instructions and documentation.
You take an efficient and organized approach to assembly projects.
Hands on experience assembling parts. We don’t expect any complex machining experience, but you should feel comfortable working with metals and metal tools, e.g. an angle grinder.
Determine with the engineering team what checks are required to ensure the assembly is correct and carry them out.
High attention to detail. You should be able to do quality spot checks and spot mistakes in your own and your peers’ work.
You understand the importance of following procedures when relevant, e.g. bolt selection and tightening torques.
Being able to read a bill of materials, organize and collect parts and off the shelf components.
Strong communication skills. You are able to sit down with an engineer, look at a design together and discuss how to approach a new build while feeding back improvements to them after finishing a project.
Why Monumental?
Joining Monumental means being at the forefront of a movement aimed at making significant strides in the construction industry. Here, your work has the potential to impact not just the company but the future of how we build. If you're driven by innovation, eager to tackle complex challenges, and ready to make a tangible difference, we want to hear from you.
