You will bring deep expertise and technical leadership to help us build fast, reliable, and intuitive solutions that empower our partners – enabling them to more easily manage jobs, streamline operations, and maximize their growth potential within our manufacturing marketplace.

Responsibilities
  • Hands-On Technical Leadership: Your primary role is writing and reviewing architectural plans for new projects, and then participating in implementation with the team.
  • Guide Innovation: Champion the adoption of a good mix of traditional and cutting-edge technologies and methods. You have the experience to guide us out of “our way” of doing things when needed, and to double down on our existing tech and methods where appropriate.
  • Teaching & Mentorship: You will serve as a mentor and guide to engineers across the organization, teaching and mentoring them to grow their skills.
  • Code Review: You will do code review and mentor others within the organization to perform good code reviews.
  • Operational Excellence: Guarantee the delivery of superior software that not only meets but exceeds customer expectations, while aligning with the strategic business timelines.
  • Collaborative Strategy: Forge strong partnerships with product managers, designers, and company leadership to promote a culture of open communication, good collaboration, and high standards.
Qualifications
  • 10+ years of professional software development experience in a fast-paced, product-driven environment.
  • Marketplace product experience is highly desirable, with an understanding of scaling multi-sided platforms.
  • Strong technical expertise in full-stack development, including:
  • Backend development with Python (services, APIs, data-driven systems).
  • Backend microservices and REST API design using Node.js.
  • Frontend development with React and TypeScript, with a focus on scalable UI design and usability.
  • Experience with AWS is required, including deploying, monitoring, and scaling production workloads.
  • Proven leadership skills, with the ability to set technical direction, mentor engineers across levels, and influence product and business decisions.
  • Excellent communication and collaboration abilities, comfortable engaging with both technical and non-technical stakeholders, from junior ICs to executives.
