About the Role

~1 min read

Join our engineering team as a Senior Software Engineer and play a crucial role in building the solutions that power manufacturing shops. You’ll work across the full stack — designing backend services and building rich, user-facing experiences — and take ownership of meaningful slices of the product. You’ll work with a modern tech stack, solve complex problems, mentor other engineers, and help shape how we adopt AI across our engineering workflow. This role is ideal for engineers who pair technical excellence with a drive for customer impact.

  • Technically Excellent: You combine deep technical skill with a passion for delivering value to customers, and you build scalable, maintainable systems that meet real-world needs.
  • Customer-Driven Innovator: You thrive in environments that encourage innovation and you’re driven to build products that make a difference.
  • AI-Fluent with Good Judgment: You use AI tools to multiply your output while owning the quality, reliability, and security of what you ship, and you know when to lean on them and when not to.
  • Lifts the Team: You help the engineers around you get better, sharing what you know and raising the bar through code review and mentorship.
  • Customer-Centric Focus: We put our customers at the center of everything we do. Your work will directly contribute to their success.
  • Modern Technology: We work across a modern stack — Python (Django and FastAPI), TypeScript and React, PostgreSQL, and AWS — and we're actively investing in how AI can accelerate our software development lifecycle.
  • Complex and Meaningful Challenges: Our software is used in critical industries like aerospace and defense, requiring robust, secure, and scalable solutions. You’ll be solving problems that truly matter.
  • Collaborative and Inclusive Culture: We believe that diverse teams build better products. Our culture emphasizes collaboration, continuous learning, and mutual respect.
  • Growth Opportunities: You’ll mentor others, influence technical direction, and grow with us as we scale.
