JOB OVERVIEW

ABOUT THE PROJECT

AI Bands is a fast-growing fitness tech startup building the future of connected workouts. We are developing a modular smart resistance band platform featuring automated tension tracking, rep detection, and real-time AI-guided coaching.

We are moving fast. We need a skilled, meticulous electronics hobbyist or hardware engineer based in the Philippines to source components locally, assemble two working prototype units, flash basic firmware, and ship the completed units to our team in the United States.

THE PARTS ENGINE (100% Reimbursed)

You will source all components locally using platforms like Lazada, Shopee, or local electronics shops.

AI Bands reimburses your components cost in full immediately upon receipt of clear, itemized digital receipts.

Total Build Allocation (For 2 Working Units):

• ESP32 Microcontrollers (x2)

• Load Cells + HX711 Amplifier Modules (x2)

• MPU-6050 IMU Modules (3-axis accelerometer + 3-axis gyroscope) (x2)

• LiPo Batteries — 1000mAh (x2)TP4056 USB-C Charging Modules (x2)

• ABS Project Enclosures (x2)

• Heavy-Duty Resistance Band Sets with handles (x2)

• Miscellaneous Shop Kit: Wire sets, jumper cables, heat shrink, nylon attachment straps.

WHAT YOU WILL DELIVER

• Two Fully Assembled Prototype Units: Clean soldering, solid wire management, and securely housed electronics inside the ABS enclosures integrated seamlessly with the bands and handles.

• Flashed BLE Firmware: ESP32 microcontrollers flashed with baseline Bluetooth Low Energy (BLE) firmware to stream data strings (spec sheet provided upon hire).

• Component Verification: Proven sensor output data streams from the load cell, HX711, and MPU-6050.Build Documentation: Clear photo updates log recorded at each stage of the wiring and assembly.

• Engineering Notes: Brief written summaries detailing any component substitutions, technical challenges, or hardware optimization suggestions.

• Secure Packaging & Courier Handoff: Finished prototypes securely packed and shipped to our corporate address in the US (All international shipping costs are covered in full by AI Bands via Wise).

SKILLS REQUIRED

• Precision Bench Skills: Professional soldering, wiring configuration, and basic troubleshooting of low-power small electronics.

• Microcontroller Literacy: Hands-on experience flashing and debugging ESP32 or Arduino environments.

• Spec Sheet Competence: Fully comfortable reading schematic lists, pinout guides, and technical build specifications.

• Documentation Discipline: Organized habits when logging build milestones and capturing clean progress photos.

• Prior Build History: You must have physical, real-world examples or photos of functional hardware or DIY electronics you have built with your own hands.

NICE TO HAVE (But not required):

• Custom BLE firmware optimization experience.

• Access to a 3D printer for custom interior component brackets or housing modifications.

• Familiarity with load cell strain-gauge calibration properties.

• Prior experience building wearable technology or fitness tracking hardware.

YOU ARE A GREAT FIT IF YOU:

• Have actually built real things that turn on—not just simulations on paper.

• Communicate proactively and transparently the same day a part is defective, delayed, or requires a technical substitution.

• Take true ownership of your workspace and meet timeline benchmarks without daily oversight.

• Can interpret a technical spec accurately while using solid judgment when minor structural details are open-ended.

HOW TO APPLY

To ensure you possess the strict attention to detail required to build our hardware, applications that use automated templates will be automatically filtered out. Please reply with:

1. A 2–3 sentence summary detailing your practical electronics, wiring, or microcontroller background.

2. Photos, links, or attachments showing functional hardware, circuits, or DIY electronics projects you have assembled in the past.

3. Your current city location in the Philippines and your estimated timeline to complete the build once parts arrive.
