Mechanical Assistant (m/f/d)

Monumental

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.   Read more on why we believe you should spend your time working on construction, and learn about our vision and company. You might enjoy Based in Europe’s film on how we’re fixing Europe’s housing shortage, or this video by Andreas Klinger of what our office looks like. About the role We are looking for an electronics technician to join our team. You will support our mechatronics engineers and work closely with our hardware and software engineering teams. In this role, you'll play a crucial part in developing and manufacturing our construction robots. Your work will directly contribute to bringing our robots to life. Join our mission to bring automation to the construction industry to create affordable, beautiful, high-quality housing for everyone. You will own electronics assemblies and build them at scale, occasionally building prototypes of our construction robot hardware, including our autonomous ground vehicles, construction cranes, supply systems, end effectors . You will also be responsible for maintenance, troubleshooting, and root cause analysis of failure modes in our existing fleet of robots. On a non-technical level, we are looking for someone who loves nothing more than working in a highly collaborative team to solve complex problems and bring novel inventions to the world. You thrive in a fast-paced environment, are excited to continuously learn new skills, and love challenging conventional ideas. After doing an assembly, you actively ask yourself how you could do it ten 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 * Owning production assembly batches for our fleet of robots, with consistent quality and speed. * Collaborating closely with our hardware and software engineering teams to refine designs based on real-world testing and feedback. * Implementing and improving procedures for electronic assembly and testing, ensuring reliability and efficiency in our prototypes and production models. * Troubleshooting of electronic components and systems for our autonomous construction robots, related accessories, and supporting systems. * Managing inventory for electronic components and tools, suggesting improvements for our robot production to prevent project delays. * Assisting in the field tests of our robotic systems, providing technical support and insights to enhance performance. * Maintaining our current fleet of robots, performing occasional health checks on them and ensuring that they are always in great state and ready to be used on site. What we’re looking for * You have a solid understanding of electronics fundamentals, with hands-on experience in hardware assembly and debugging across tasks such as soldering, cabling/wiring/crimping. Being able to read schematics is great, however our systems are mostly cabling and wiring at a system level rather than detailed PCB schematics, so we need someone who's comfortable adapting without one. * You're adept at identifying issues and coming up with efficient solutions. Your background allows you to intuitively understand how electronic components could or do fit into larger systems. * Comfortable using hand tools for mechanical assembly, not just electronics. Many of our builds involve small mechanical fixtures and hardware alongside the wiring. * In our fast-paced startup environment, priorities can shift quickly. You're comfortable with context-switching and can handle multiple tasks efficiently. * Your excellent organisational and communication skills mean you can articulate complex ideas clearly and work collaboratively with engineers to refine designs. * A BSc, HBO, MBO, diploma or equivalent in a relevant field, with a minimum of 2 years of comparable work experience. An engineering or technical degree would be a bonus. 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.   For open applications (where you don’t see an exact role match), please reach out to us at: iwanttojoin@monumental.co - share with us the most interesting or challenging project you’ve worked on, why you want to join and your CV or portfolio.   Unfortunately we do not currently support internships.   If you don’t meet all the qualifications here but are excited about Monumental and feel you’d still be able to help us solve difficult problems, do get in touch. We welcome generalists who focus on outcomes and are eager to learn on the job.

You are a maker, who enjoys building physical things from start to finish, with a bias for speed and simplicity. You enjoy contributing across the entire engineering process: asking the right questions to scope a problem, doing back of the envelope calculations, fabricating parts in our workshop, testing your design live on a construction site and iterating on it to produce a robust and scalable design. We’re tackling some of the hardest problems in construction robotics: full on-site autonomy, lifting construction-scale payloads, reliable operation at height, and millimetre-level positioning accuracy across our entire technology stack. We’re looking for people who are genuinely excited to lead these efforts alongside a highly capable and supportive team. Our approach to building robots has focused on identifying the key areas that need de-risking and tackling them head-on through rapid prototyping. This has allowed us to achieve remarkable results in a surprisingly short amount of time, defying conventional expectations. If our approach excites you, this role could be a great fit for your interests and skills.   What you’ll do Imagine a fleet of autonomous robots rolling onto a construction site in the morning and by sundown, a fully built, beautiful home stands ready for a family to move in. That’s the future we’re building. Today, our robot systems are already constructing real homes across the Netherlands at scale. But we’re just getting started. Your work won’t be about incremental improvements, you’ll tackle broad and novel problems that unlock autonomous construction: * Pushing toward full robot autonomy for our masonry systems: automated wall-anchor installation and mortar pointing to produce beautiful brickwork. Autonomous lift platforms and fully automated material-supply enabling our fleet to work uninterrupted across large, messy sites. * Designing for reliability: our robots need to be tough enough to survive months of harsh construction conditions, yet serviceable and redeployable in under 24 hours. * Building next-gen hardware to expand what our robots can do: higher-precision brick placement, larger payloads, expanded build envelopes, hot-swappable end effectors, and operation in tight, constrained spaces like scaffolding. * Getting hands-on in the field: you’ll join deployments where we’re building real homes, whilst stress-testing systems and uncovering the edge-case problems that can only be found in the field.   What we’re looking for * A proven record of being a builder and being able to work autonomously: you can point us to example of shipped projects where you were the driving force of getting something done. This can be in a professional context, in a top student (”dream”) team, or even just personal side projects. * Experience in designing and delivering products from concept up to low series volume. * Proficiency in rapid prototyping, 3D printing, machining, and milling to make product designs a reality. * Deep knowledge of mechanical systems and structural dynamics: e.g. statics, mechanics of materials, dynamics, vibrations, material science, and controls. * Expertise with 3D CAD modeling with complex parts and assemblies, e.g. OnShape, Solidworks, or Siemens NX. * Expertise in multi-physics simulations (FEA) applied to structural designing problems, e.g. Comsol and Ansys, but also being able to do hand calculations when that makes the most sense. * Experience selecting, sourcing, and integrating electronics components (e.g. actuators, sensors, cameras) into hardware design. * Being able to write (embedded) code in C or C++ is a plus. * B.Sc. in mechanical, mechatronics, or robotics engineering or similar experience is a nice to have   Why Monumental?

About the role Monumental are looking for a mechanical engineer to mature our current robot design and enable us build out and deploy a thousand-strong robot fleet to build beautiful, bespoke buildings. Our robots are deployed on sites across the Netherlands and the UK and will be in the US within a year. Most robotic applications require robots to function in controlled, clean environments. This is not the case at Monumental. Our robots must be reliable enough to withstand the harsh realities of a construction site: rain, dirt, temperature cycles and impact. This role will focus on improving the reliability of our robots, so that our growing fleet will survive months on construction sites with minimal maintenance. Expect to be regularly on site, so you know our product inside out. If you want an office job, this isn't the role for you. For more context on building hardware at Monumental, read Niall’s Substack on why he quit his job and moved country to make robots to fix Europe’s housing crisis. What you'll do * Own making sure our robots can build on construction sites for months with minimal downtime. Like most things at Monumental, we track this using the number of deployment bricks laid. You'll get us to 12,000 bricks laid before a hardware failure. * Rapidly understand how our robots work, the hardware that goes into them, and their failure modes. Systematically improve their design with respect to reliability, and conduct rigorous testing to validate the improvements. * Own the loop from discovering a failure in the field to a validated fix shipped to the fleet. Root cause the failure, design and test the fix in the office, then validate it holds up in the field. * Make sure R&D hardware is validated before it scales. Define validation criteria for hardware, design rigs for reliability testing, and raise the bar for validation within the hardware team. * Work with the maintenance team, both in the office and on deployments. Find maintenance pain points and fix them. What we're looking for * 2+ years of experience in reliability and test engineering, ideally in robotics. You have taken hardware that didn't survive its environment and made it robust. * Strong experience with environmental and mechanical reliability tests: IP, temperature, vibration and shock. You have designed and built the test rigs and run the analysis yourself. * Experience making and repairing electromechanical assemblies. * Experience shipping hardware from prototype through to medium-series production. * Strong knowledge of GD&T, and producing 2D and 3D drawings. Nice-to-haves * BSc in Mechanical, Electrical, Manufacturing or Industrial Engineering, or equivalent. * Examples of delivering complex electromechanical assemblies that operated at scale in harsh environments. * Experience developing accelerated life reliability tests. * Experience with electric motors, gearboxes, or actuators Why Monumental?
