About Assembly OSM

Assembly OSM is a fast-growing, Fifth Wall-backed company on a mission to make urban development more scalable and sustainable. We are a NYC-based modular design builder with decades of experience in real estate development, public-private partnerships, offsite construction, and manufacturing. We are hard at work developing our first two buildings in New York City, and growing the team to allow us to really take Assembly to scale.

Our team has developed billions of dollars of urban real estate including the tallest high-rise modular tower in North America (461 Dean Street), and has led major manufacturing operations at companies like Tesla and General Motors.

The Assembly approach is quite different than the modular solutions that have been deployed in the past. The process is more similar to aerospace manufacturing than construction -- leveraging high fidelity digital twin models and distributed manufacturing to make our business more scalable and resilient.

If our mission speaks to you, we encourage you to apply!


Assembly OSM’s Product Design & Engineering team seeks a highly organized, detail oriented professional who excels in precision modeling of complex plumbing and sprinkler piping systems. If you are passionate about detailed high-quality engineering, have an in-depth understanding of piping systems, and thrive in a collaborative/fast-paced setting, this is the role for you.

You will:

  • Join a diverse team of architects, manufacturing engineers, and industrial designers responsible for the design, development, and product validation of prefabricated MEP components
  • Design and model intricate building piping systems to a fabrication level of detail using advanced 3D modeling software.
  • Produce detailed shop drawings and comprehensive bill of materials for piping systems.
  • Create work instructions, assembly drawings for customers which may include suppliers of combined products as well as the internal modular assembly process.
  • Coordinate effectively with various teams to ensure seamless integration of piping system components and supporting elements built into products and coordinated with overall building projects.
  • Apply your experience in systems design, possibly gained in adjacent industries, to innovate and improve existing piping solutions.
  • Maintain rigorous attention to detail in all aspects of work, from planning to execution.
    Assist in defining product requirements, standardized data sheets, and specifications.
  • Develop test criteria in support of data sheets and for work instruction inclusion.
