About Assembly OSM

Assembly is on a mission to make urban growth scalable, sustainable, and inclusive. Novel technology, enabling aerospace levels of precision, allows us to design and deliver high-rise buildings quickly, at less cost, and more efficiently than ever before. Assembly buildings are custom, imaginative, green, and peerless in quality—all while creating market-driven affordability, enabling diverse participation in building delivery, and bringing design excellence to more and more communities.  We’re currently a tight-knit group of 30 with plans to scale both our team and impact substantially this year. If our mission speaks to you, we encourage you to read more from our leadership team and to apply to join us.


About the Role

As a Mechanical Engineer at Assembly, you will collaborate with a multidisciplinary team of designers, prototypers and engineers to accelerate development of Assembly’s products and enable rapid, repeatable production of high quality prefabricated high-rise building assemblies.  Successful candidates will demonstrate a high level of initiative, autonomy, and integrity, as well as a passion for advancing sustainable construction.

You Will:

  • Collaborate with Assembly’s cross-functional teams and suppliers to efficiently convert product designs into manufacturable and scalable products.
  • Perform detailed design of various components, structures, and building modules
  • Perform detailed analysis including, tolerance and statistical analysis, significant/critical characteristics, establishing key product Interfaces and characteristics aiming for quality, manufacturability, scalability and reliability.
  • Lead cross-functional Product Engineering Design reviews with the objective of Design for Excellence. (DFx)
  • Manage product design change control through PLM to ensure a single source of truth.
  • Support prototyping, test, feasibility studies, cost reduction and R&D/innovation initiatives; Write test plans, review setups, review test data and provide recommendations.
  • Drive of development and implementation of Bill of Design, Bill off Engineering and Bill of Process to enable continuous improvement of product and process.
  • Support Tier 1 manufacturing process development and bring up; capturing lessons learned.
  • Support supplier selection, development and quality assurance activities.
  • Collaborate on projects and programs with AOSM cross-functional teams including, program management, architectural, design, supply chain, & manufacturing.


You Are:

  • An experienced Mechanical Engineer. You have been a part of product design and engineering of complex products, large, small, or both. Assembly OSM may be out of your comfort zone, but you are up for the challenge.
  • A problem solver. You recognize the issue, and are able to synthesize data from various sources. You can quickly develop and propose solutions but are also able to take critical feedback. You seek the best solution for the customer and business.
  • Excited to work in a dynamic environment. You’re ready for the challenge of navigating change as we embark on advancing the construction industry, accommodating many different business needs and objectives. You like to wear many hats and don’t mind getting your hands dirty sometimes.
  • Extremely detail-oriented. Keen attention to detail. You take pride in doing excellent design and engineering work but understand and are willing to take appropriate trade offs.
  • Proactive: You have experience managing complex schedules and competing priorities that require thinking ahead and anticipating conflicts.
  • An excellent communicator. You tend toward overcommunication in situations that lack clarity, and try to keep all relevant parties in the loop. You can build and maintain successful, trusting work relationships.

You Have:

  • Highly proficient using 3D parametric modeling software (e.g. CATIA, SolidWorks, etc.)
  • Sound engineering fundamentals in design, standards & specifications, statics, finite element analysis dynamics, stress analysis and material science.
  • Experience and demonstrated capability with Geometric Dimensioning and Tolerancing per ASME Y14.5 and ASTM, ANSI, ISO, ASME, NFPA , etc.
  • Experience with DFMEA and PFMEA methodology and implementation.
  • Familiarity with process simulation software and/or “digital twins” (e.g. Delmia, Tecnomatix)
  • Experience in automotive, aerospace, facade and/or building product manufacturing
  • Experience with metrology / measurement tools (e.g. fixturing, gaging, CMM)
  • Knowledge of core manufacturing methods (CNC, Welding, etc.).
  • Proficient at project management, able to forecast task requirements, complexity, and resource requirements.
  • Preferred, but not essential: Knowledge of construction (AEC) techniques.
  • Preferred, but not essential: Familiarity with PLM (e.g. ENOVIA, Arena) and change control process; MES, QMS, ERP.

Salary Range: $85,000-$100,000 per year
