Mid/Senior Software Engineer, Product Development

Knightscope•Sunnyvale, CA

1d•$150,000 - $180,000•Onsite

About The Position

Knightscope is seeking a Mid/Senior Software Engineer to join their product development team and support a new hardware program. The role involves architecting and owning the software for a wearable technology product's check-in/check-out system, from early prototyping through production readiness. This includes the overall architecture, sensor/reader integration on the edge device, the data pipeline (APIs and messaging), database design, and cloud connectivity. The engineer will collaborate cross-functionally with mechanical, electrical, and systems engineers in a fast-paced, gate-driven product development environment and will play a critical role in shaping a first-of-its-kind platform. This is an ownership-driven position requiring a hands-on engineer comfortable operating in ambiguity and driving decisions across different engineering disciplines. The individual will own the full software scope of a new wearable hardware product.

Requirements

B.S. or M.S. degree in Computer Science, Electrical Engineering or a related field.
7+ years of software engineering experience, including building IoT or hardware-integrated systems.
Experience with RFID/NFC protocols (ISO 14443, ISO 18000, EPC Gen2).
Familiarity with serial communication (UART, SPI, I2C) to talk to readers.
Basic electronics understanding.
Experience with Raspberry Pi, Arduino, or industrial edge devices.
Experience with REST API development.
Experience with MQTT or WebSockets.
Basic networking knowledge (TCP/IP, WiFi, LAN).
Version control (Git).
Basic database design (SQLite, PostgreSQL, MySQL).
Understanding of system design – designing reliable, real-time systems.
Understanding of event-driven architecture.
Python, C or C++ (if firmware/hardware-level coding).
Understanding of how RFID readers communicate.
Ability to read and parse tag data.
Basic knowledge of RFID protocols (EPC Gen2 or NFC standards).
SQL basics — storing check-in/check-out records (who and when).
Experience with cloud platforms (AWS IoT, Azure IoT Hub, Google Cloud IoT).
Familiarity with Docker or basic DevOps.
Computer Vision basics (OpenCV) as a complementary skill.
Experience with access control systems.

Responsibilities

Architect and own the software for a wearable technology product’s check-in/check-out system.
