Role Description

Mosaic is a construction technology company focusing on homebuilding. We serve as a turn-key general contractor for medium-sized homebuilders while also developing a software platform that we use to automate and streamline our construction operations. Our vision is to leverage our platform to create the world’s most scalable homebuilding operation and to empower homebuilders everywhere.

Today, with our Series A led by Andreessen Horowitz, $24M+ in total funding, and a recent $100M partnership with a best-in-class, innovative homebuilder, we’re launching our platform to build better communities together with our partner towards our mission of making places people love and making them widely available.

We have one speed at Mosaic: full speed. With over 100 homes under active construction, we have an incredible advantage over the rest of the construction technology industry. Our ability to move quickly, stay nimble, and embrace change is critical to maintaining that advantage. Our strategy, projects, titles, and focus may change. But what will not change is our speed. Individuals who exhibit and resonate with these values are likely to find success with us. You can read more about Mosaic and our mission here.

  • Design systems that strike the appropriate balance between scalability and complexity
  • Perform and participate in the entire lifecycle of new systems and features, from prototyping and spec'ing to implementing and testing

  • Bachelor’s degree in Computer Science, Engineering, or equivalent experience

  • Strong communicator, particularly for technical writing and data model design
  • Exceptional teamwork skills and partnering with remote teams

Just as we seek to create communities that help people discover their purpose, so do we seek to create a team culture that can do the same. As a team, we meet once every month or two in for a multi-day retreat in different destinations across the US. We call these Heartbeat meetings and its a time for the entire team to come together, discuss strategies, business, cook meals together, play board games and go on hikes.
