What are the key skills and qualifications needed to thrive in the software engineer startup position, and why are they important?

To thrive as a Software Engineer in a startup environment, you need solid programming skills, a problem-solving mindset, and a degree in computer science or related experience. Familiarity with agile methodologies, cloud platforms, version control (like Git), and rapid prototyping tools is highly valued, and startup engineers may also benefit from exposure to full-stack development. Adaptability, effective communication, and the ability to work independently in uncertain environments are standout soft skills. These competencies enable engineers to rapidly iterate on products, effectively collaborate across small teams, and contribute to the dynamic demands of a growing company.

What is a software engineer startup?

A Software Engineer Startup job involves developing, testing, and maintaining software in a fast-paced, early-stage company. Engineers in startups often wear multiple hats, working on both backend and frontend development, infrastructure, and sometimes even product decisions. The role requires adaptability, problem-solving skills, and the ability to work with limited resources. Unlike larger companies, startup engineers may need to prototype quickly, iterate based on user feedback, and contribute to the overall growth strategy. This position is ideal for those who enjoy dynamic environments and taking ownership of projects.

What can I expect from the daily work environment as a software engineer at a startup?

Working as a Software Engineer at a startup typically means you'll be part of a small, agile team where roles and responsibilities can shift quickly based on company needs. You'll often participate in daily stand-ups, collaborate closely with founders or product leads, and have the opportunity to contribute ideas beyond your core coding tasks. The pace is usually fast, and you'll likely wear multiple hats, working on everything from prototyping new features to troubleshooting production issues. This hands-on, collaborative atmosphere provides excellent opportunities for skill growth, creative problem-solving, and making a visible impact on the company's direction.

Job description

At Layup Parts, we're developing the technology that will build the future. 

We're a manufacturing technology company replacing months of lead time with days, using proprietary software, automation, and advanced manufacturing systems built for speed. Our customers are inventing what's next, in aerospace, defense, robotics, and beyond. To keep up with them, manufacturing has to change. That's what we're building. 

We are looking for highly motivated Software Engineers to join our team as key members of our growing engineering function.  This is a high-impact role that presents a unique opportunity to make decisions that shape the technical trajectory of Layup. You are an ideal candidate if you are looking to join an exceptional team and play a significant role in the growth and success of an early-stage startup. We can hire at various levels and need both frontend and backend skillsets. It's also ok to be more frontend or backend leaning. 

What you will do:

  • Build and expand our proprietary Factory Operating System, the software platform that orchestrates production from quote to shipment. 

  • Develop interfaces and integrations for manufacturing equipment, capturing real-time production data and turning it into actionable insights. 

  • Implement features for our customer portal, creating a seamless experience from project submission through delivery. 

  • Create internal tools that automate workflows, eliminate bottlenecks, and increase manufacturing throughput. 

  • Partner closely with manufacturing, operations, and production teams to solve real-world problems through software. 

  • Mentor teammates and help foster a culture of technical excellence, curiosity, and continuous improvement. 

What We're Looking For:

  • Be awesome! Be the kind of person you want to work with! 

  • 4+ years professional software engineering experience. 

  • Strong engineering fundamentals and a bias toward building reliable, maintainable software. 

  • Ability to drive projects single handedly without much guidance or input. 

  • Experience in startups or small teams in fast-paced and quickly changing environments.

  • Ability to quickly understand and navigate complex systems and established code bases 

  • Excellent communication skills and the ability to collaborate across engineering, manufacturing, and operations teams. 

Preferred:

  • Experience with Go, Typescript or Rust.

  • Experience working with manufacturing systems, industrial automation, MES, ERP, or machine integrations. 

  • Experience designing software related to 3D part representations or manipulation in a CAD/CAM program or similar. 

  • Familiarity with customer facing software applications.

  • Understanding of mechanical engineering, manufacturing processes, or composite part production. 

$130,000 - $200,000 a year
Final compensation is based on your experience, skills, and what you bring to the table. 
Full Benefits Package: Medical, dental, and vision coverage, short- and long-term disability insurance, company-paid life insurance
