About The Role

As a Senior Systems Developer (Python & Linux), you will play a key role in building and evolving the software systems that power our large-format Hylo™ 3D printers and our Basis™ SaaS platform.

• Build automation and tooling that supports our in-house manufacturing line and factory operations
• Improve and maintain CI and build pipelines, including GitHub Actions and OS build workflows
• Troubleshoot production issues on deployed printers using logs, CLI tools, and remote access, and implement durable fixes
• Design software systems that are maintainable, testable, secure, and resilient, avoiding fragile or ad-hoc solutions
• Collaborate with cross-functional teams including hardware, manufacturing, and customer-facing teams to solve complex problems
