Senior Embedded Hardware Engineer (IoT / Electronics Systems)

About Arculus

Arculus is building Arculus Boxx, a secure, connected delivery enclosure designed to prevent package theft, verify delivery, and operate reliably in real-world environments. This is a physical, real-world product involving power, batteries, cameras, displays, locks, sensors, and connectivity — not a slide deck or concept app.

We are currently in EVT / Rev A, focused on producing a fully functional demo unit that will be used for marketing, trade shows, and customer presales ahead of an initial production run.

The Role

We’re looking for a Senior Embedded Hardware Engineer to take ownership of the electronics system end-to-end.

This role starts with rapid prototyping using off-the-shelf components, then transitions into custom PCBA design once the architecture is validated. You will be building something that actually ships — not just designing in isolation.

What You’ll DoPhase 1 – EVT / Demo

Architect and assemble a working electronics system using off-the-shelf components, including:

• Compute module / SBC / SoM
• External and internal cameras
• High-clarity, display-only screen (non-touch)
• NFC module
• Internal and external LED systems
• Lock drivers (2–3 channels)
• Battery backup and power management
• Sensors (IMU / tamper, internal & external temperature)

Define:

• Power distribution
• Cabling and connectors
• Mounting, airflow, thermal, and EMI considerations
• Integrate electronics into a final-form 3D-printed enclosure
• Produce interim documentation:
• BOM
• Wiring diagrams
• Bring-up and test procedures

Phase 2 – DVT / Production

• Translate the validated system into custom PCB designs
• Own schematics, layout reviews, and DFM/DFT considerations
• Support manufacturing handoff and early production refinement

What We’re Looking For

• 5+ years experience in embedded hardware / electronics systems
• Proven experience shipping real hardware products
• Strong background in:
• Power systems (AC + battery)
• Cameras and displays
• LEDs, motors, solenoids, or lock mechanisms
• Sensors and environmental monitoring
• Comfortable working with evolving requirements and imperfect prototypes
• Pragmatic, execution-focused mindset

What This Role Is Not

• A layout-only PCB designer role
• A research or academic position
• A slow, process-heavy corporate job

This is a builder role for someone who wants to own what they create.

Compensation

Arculus is currently in the concept / EVT phase of development. At this stage, all team members — including founders and leadership — are foregoing direct salary compensation in exchange for profit shares in the company.

We use Slicing Pie, an industry-recognized equity framework, to track and compensate contributions fairly and transparently.

How it works:

• Every hour you work is tracked and banked
• Your time is credited at 2× your fair market hourly rate
• Contributions are converted into profit shares
• All work is tracked using Slicing Pie software and methodology

We will continue using Slicing Pie until the company reaches break-even via revenue or capital investment. At that point:

• Your role transitions to a salary-based position
• You retain all profit shares earned during the early build phase

Why Join Arculus

• Non-linear upside tied directly to the success of the product
• Full remote flexibility
• Opportunity to build cutting-edge connected hardware
• Meaningful ownership and impact at the ground floor
• Small, execution-focused, collaborative team

If you’re excited about building real hardware and want meaningful ownership in what you create, we encourage you to apply.

Job Type: Full-time

Pay: $101,832.46 - $122,636.94 per year

Benefits:

• Stock options

People with a criminal record are encouraged to apply

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?
