Senior Full Stack Engineer - (TypeScript / Express)

 2 months ago

The Company Youll Join

At Extracker we make the construction industry more efficient by using technology to better communicate project costs between companies.

Every day thousands of pounds of paper and hundreds of personnel hours are consumed to record and communicate extra work completed on construction job sites around the world.

These pieces of paper can take days or weeks to reach the office and from there need to be scanned, manually transcribed, and tediously recorded into spreadsheets, that is, if they arent lost or damaged first.

In an industry with constant change and thin margins, this results in a massive loss of valuable time and money for hard working contractors.

Extracker creates tools to help contractors dramatically increase the organization and efficiency of this system, called change order communication, by intelligently digitizing this age-old paper process. This leads to an increase in profits, more successful contractor to customer relationships, more transparency into a projects true cost, and less wasted paper!

Our offices are currently located in the Lafayette, CA with team members working in San Francisco, Truckee, and San Ramon, California and we are also open to remote candidates.

The Opportunity

Just as TurboTax did for tax documents and Expensify did for receipts and expense reports, Extracker is doing for change order communication and log management by building first-of-its-kind, category defining software that is revolutionizing the commercial construction industry.

As an early senior leading member of the team you will have an exceptional level of impact on the development and iteration of our product as well as the workplace culture and team itself.

This is your chance to join a team that is bringing game-changing, modern web tools and dynamic financial analysis systems to a stagnant, static, pen and paper part of the commercial construction industry.

The Role

We are looking for an experienced Senior Full-Stack Software Engineer to join our web app development team. We are primarily a JavaScript/TypeScript based stack, and employ a variety of modern tools and technologies. As a full-stack developer at Extracker, you will be responsible for developing and designing front-end web apps as well as the backend APIs and services that power them. You will work with upper management to define software requirements and take the lead on operational and technical projects. You should have excellent communication, organization, and problem-solving skills. You should also have experience mentoring other engineers.

The Problems Youll Solve:

As a full-stack developer at Extracker, you will play a critical role in making sure our front-end web apps and back-end services are serving the needs of users in the commercial construction space.

  • How Extracker, can continue to be a leading category defining platform, and can establish ourselves technologically as the industry gold standard for digital Time and Material Tag documents and Change Order Request communications.
