Full Job Description
About Arculus

Arculus is building Arculus Boxx, a secure, connected delivery enclosure that combines hardware, firmware, and connectivity to solve a real-world problem. This role is focused entirely on the device side — the firmware that makes the system reliable, connected, and demo-ready.

We are in EVT / Rev A, preparing a live demo unit that communicates with a mobile app and backend over Wi-Fi.

The Role

We’re looking for a Senior Embedded Firmware Engineer to own the device-level firmware for Arculus Boxx.

You’ll work closely with hardware and product leadership to turn evolving electronics into a stable, connected system suitable for demos, presales, and early customers.

What You’ll Do

Develop firmware supporting:
Wi-Fi connectivity
BLE-assisted or AP-mode provisioning
Secure HTTPS communication with backend services
Implement device logic for:

Power states (wall power + battery backup)
Camera capture workflows
Lock control
LED behavior (internal & external)
Tamper detection and alarms
Internal and external temperature sensing
Build:

Event logging and store-and-forward behavior
JSON-based backend event uploads
Basic command handling (e.g., capture image, flash LEDs)
Support OTA firmware updates (EVT-level)
What’s In Scope (EVT)

End-to-end, demo-ready firmware
Reliable behavior under real-world conditions
Clear logging and debuggability
Explicitly Out of Scope (for now)

Production-grade security hardening
Advanced analytics
Continuous video streaming
Mobile app development
Backend architecture ownership
What We’re Looking For

5+ years experience in embedded firmware / IoT
Experience with:

Wi-Fi and BLE
REST-based backend communication
OTA updates
Embedded Linux or RTOS environments
Comfortable working alongside evolving hardware
Bias toward shipping and iteration over perfection

Application Question(s):

This role uses a Slicing Pie–based compensation model during the pre-revenue phase. Contributions are tracked and converted into profit shares; there is no cash salary until break-even or funding.
Have you read and do you understand this compensation structure?

Why are you interested in a contribution-for-equity/profit-share model at this stage of a startup?
How many hours per week can you realistically contribute to this project over the next 3–6 months?
Early-stage startups often involve ambiguity, rapid iteration, and limited structure. How comfortable are you operating in this type of environment?
