Job description

Constrafor is rebuilding the financial infrastructure behind one of the largest industries on the planet and we're doing it fast! Construction moves trillions of dollars a year, yet it still runs on outdated processes, cash flow guesswork, and paperwork chaos. We're the SaaS and fintech platform fixing that, giving General Contractors and Subcontractors the tools to manage procurement and financial transactions the way modern companies actually operate. Backed by $30M+ in VC funding and scaling fast, we're not just building software, we're building the operating system for construction finance. If you want your work to have real, tangible impact on an industry that touches literally everything around you, this is that opportunity.

We're seeking an exceptional Full Stack Engineer to join our dynamic team and lead the development and maintenance of our platform's core functionality across both frontend and backend systems. In this role, you'll collaborate closely with the Head of Engineering and Product teams to deliver scalable, high-performing, and intuitive solutions. As a senior member of our team, you'll take on complex, high-impact projects that require strategic thinking, technical depth, and strong product sensibility. This position offers the opportunity to drive innovation across the organization. If you're a seasoned engineer with a passion for building seamless, high quality user experiences in a fast-paced startup environment, we'd love to hear from you.

???? What You'll Do:

  • Lead the design and development of high-quality software across the full stack, ensuring scalability, performance, and maintainability.
  • Build and optimize user facing applications while seamlessly integrating them with robust backend services.
  • Collaborate with sales and product teams to prioritize and deliver features that directly impact revenue growth and customer success.
  • Implement best practices for security, testing, and deployment across both front-end and back-end systems.
  • Engage with customers and internal stakeholders to understand their needs and translate them into elegant technical solutions.
  • Share knowledge across the team and contribute to a culture of technical excellence.

???? What You Bring:

  • 5+ years of experience developing and scaling full stack web applications in a fast-paced environment.
  • Proficiency in Python, Django, Postgres, and AWS, with solid experience in front-end frameworks such as React or Next.js.
  • Deep understanding of RESTful APIs, modern web architecture, and front-end performance optimization.
  • Proven experience building and maintaining complex SaaS products with strong attention to usability and scalability.
  • Strong leadership and communication skills, with a track record of owning projects from concept to completion.
  • A passion for mentorship, clean code, and continuous learning.

???? Constrafor Benefits:

  • Competitive Salary: $180k-205k DOE.
  • Equity ownership within Constrafor.
  • Hybrid office schedule (3 days out of our Hudson Yards office)
  • Medical, dental & vision insurance coverage offered for you and your dependents.
  • Generous PTO Plan.
  • A collaborative and innovative work culture that values your input.
  • Opportunity to make a significant impact in a growing tech company.
