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 you and this role

We’re looking for a Purchaser who’s organised, proactive, and ready to help build our supply chain from the ground up. You’ll play a key role in making sure we have the right parts at the right time to keep our robot production running smoothly. This includes working with suppliers, tracking lead times, placing orders, managing stock levels, and helping set up the tools and processes we need - starting with spreadsheets and later helping us move to an ERP system. You’ll also work closely with engineers to get drawings and specifications, check them for completeness, and make sure suppliers have what they need to deliver parts that meet our requirements.

You will own, and iterate on our existing procurement systems and built new ones to reduce lead times in our supply chain. Monumental is a unique company in that we’re solving the problem of on-site construction with a vertically integrated offering. We’re a hard tech company doing real R&D, financed through venture funding. We manufacture our hardware in-house, run a fully equipped workshop, manage a complex supply chain, and deploy masonry robots to construction sites across the Netherlands, and the UK.

You’ll be part of a small and growing operations team, and solving real-world problems every day. This role is ideal for someone who enjoys the mix of structured systems thinking and the unpredictability of a fast-moving software-enabled robotic solution.

Note: we are unable to support relocation for this role. Applicants must be based in the Netherlands, and able to commute onsite to Amsterdam to be considered.

What You’ll Be Responsible For

• Work with other teams (especially engineering) to help predict what parts we’ll need to build our robots, so we can order the right items on time.

• Help set up and maintain our Bill of Materials (BoM).

• Find, qualify, and manage suppliers — bringing in new ones and phasing out underperforming ones.

• Set delivery expectations and follow up with suppliers on delays, quality issues, or inventory problems.

• Handle the sourcing and ordering of tools, materials, and supplies needed for production.

• Build and improve simple processes (initially using spreadsheets) to manage stock levels and avoid shortages or overstocking

• Provide ongoing financial forecasts of spend related to production and R&D

• Take an active role in setting up our future ERP system and help migrate procurement and inventory processes into it.

• Create clear processes to help supply chain, warehouse, and production teams work better together

What We’re Looking For

• 2–4 years of experience in a purchasing, procurement, or supply chain coordination role (ideally in a manufacturing or hardware environment, startup experience a bonus)

• Comfortable working with spreadsheets (e.g. Excel or Google Sheets) for tracking orders, inventory, and suppliers

• Strong organisational skills and attention to detail

• Basic understanding of supply chain principles, lead times, and inventory control

• Experience communicating with suppliers and managing purchase orders

• Proactive, hands-on attitude — able to take ownership and get things moving in a startup-like environment

• Good communication skills in English, both written and spoken

Nice-To-Haves

• Experience helping implement or work with an ERP system (e.g. NetSuite, Odoo, SAP, etc.)

• Familiarity with hardware bills of materials (BoMs)

• Exposure to supplier onboarding and qualification processes

• Interest in robotics, hardware, or high-tech manufacturing

• Experience working across teams like production, engineering, and warehouse

• Degree in supply chain management, logistics, engineering, business, or a related field

• Relevant experience can substitute for formal education — we value hands-on skills and a proactive mindset over titles

• Ability to communicate verbally and written in Mandarin
