Job Summary

Knightscope is seeking a Mid/Senior Software Engineer to join our product development team and support a new hardware program. In this role, you will architect and own the software for a wearable technology product's check-in/check-out system-from early prototyping through production readiness-including the overall architecture, sensor/reader integration on the edge device, the data pipeline (APIs and messaging), database design, and cloud connectivity. You will work cross-functionally with mechanical, electrical, and systems engineers in a fast-paced, gate-driven product development environment and play a critical role in shaping a first-of-its-kind platform.

Location Requirement:Full-time, on-site at Sunnyvale HQ

About the Role

The role is an ownership-driven position within a multidisciplinary program team, requiring a hands-on engineer who is comfortable operating in ambiguity and driving decisions across mechanical, electrical, and software boundaries. You will be expected to make thoughtful tradeoffs and carry designs from early concept and prototyping through to production.

This individual will own the full software scope of a new wearable hardware product, including architecting the check-in/check-out process, sensor/reader integration on the edge device, the data pipeline (APIs and messaging), database design, cloud connectivity, and testing support.

Please include the Disney character that best describes you in your resume-and make sure to ask your interviewers the same. They are expecting it.
