About The Position

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.

5+ years of experience delivering impactful software, with strong object-oriented fundamentals.
Proficiency in a modern backend web stack, such as Python/Django or FastAPI, Node/Express, or Java/Spring.
Hands-on frontend experience with TypeScript and React, building and maintaining production user interfaces.
Hands-on experience with AWS, designing and deploying scalable, resilient cloud architectures.
Experience with relational and non-relational databases, with a clear sense of when to use each.
Strong experience with API design, development, documentation, and versioning.
Expertise building and deploying applications with Docker and CI/CD tooling like Jenkins.
Practical experience using AI coding tools in a real engineering workflow, with sound judgment about where they help and where they don’t.
Strong communication skills, conveying complex technical concepts to technical and non-technical stakeholders.
US Citizenship or Green Card Holder.

Solve Complex Problems: Tackle deeply technical challenges across the stack, balancing trade-offs to deliver secure, compliant solutions that meet our customers’ needs.
Champion Engineering Excellence: Advance our practices — testing, observability, code review, and context-first documentation — so our codebase stays high-quality, performant, and legible to both humans and AI agents.
Mentor and Grow Talent: Share your expertise with less experienced engineers, fostering a culture of continuous learning.
Collaborate Across Teams: Work closely with designers, product managers, and other engineers to deliver products that exceed customer expectations.
