CAD Engineer – Portable Power‑Bank Design (Nexer) Ended
About the job
Project Overview
We’ve developed Nexer, an ultra‑fast, next‑generation portable power bank capable of fully recharging a modern smartphone in just 5 minutes. To bring Nexer from concept to reality, we need an experienced CAD engineer or product‑development freelancer who is willing to sign an NDA before receiving any proprietary technical details. Your role will be to:
Detail the industrial design (enclosure, mechanical components, thermal features)
Produce manufacturing‑ready CAD files and a complete BOM
Support prototype build & testing (fit, form, function, thermal performance, charge‑rate validation)
You’ll transform our concept sketches and spec sheet into a polished, producible device ready for certification and small‑batch production.
Scope of Work
Industrial & Mechanical Design
Refine form factors for both variants:
2‑Charge Pack: ~110 × 65 × 18 mm
4‑Charge Pack: ~130 × 70 × 20 mm
Integrate thermal‑management elements: vapor chamber, phase‑change spreaders, venting/fin geometry
Ensure CNC‑ and injection‑mold‑friendly features (draft angles, snap‑fits, fastener bosses)
CAD Modeling & Documentation
Create full 3D CAD assemblies (SolidWorks, Creo, or equivalent) of enclosure, internal trays, mounting points, connectors
Export detailed 2D drawings with tolerances for tooling, including exploded views and part lists
Generate a complete Bill of Materials (BOM) with standardized component call‑outs

Generate a complete Bill of Materials (BOM) with standardized component call‑outs
Prototype Support & Testing Plan
Recommend prototyping methods (CNC, 3D‑print, low‑run molding) and materials selection
Collaborate with our electronics team to ensure seamless integration of GaN converter, BMS board, cells, and connectors
Develop and execute a test plan covering:
Fit & assembly (mechanical tolerances, snap‑fit strength)
Thermal performance under 180 W load (< 45 °C surface)
Electrical interface (USB‑C PD port alignment, button/LED ergonomics)
Iterative Feedback & Revisions
Incorporate up to two rounds of design revisions based on prototype test results
Deliver updated CAD and drawings after each iteration
Deliverables
3D CAD package (native files + STEP/IGES exports)
2D engineering drawings with manufacturing tolerances
Complete BOM (Excel or Google Sheets)
Prototype test plan document
Test reports summarizing fit, thermal, and functional validation
Finalized CAD revisions post‑testing
Timeline
Kickoff & concept review: within 1 week of hire
Initial CAD & drawings delivery: 3 weeks after kickoff
Prototype build & testing: 2 weeks after CAD sign‑off
Revisions & final delivery: 1 week after test‑report review
Total duration: ~7 weeks
NDA Requirement
All applicants must be prepared to sign our standard freelancer NDA prior to receiving any detailed schematics, BOMs, or internal design documents.
Ideal Candidate
Proven experience in portable‑electronics enclosure design
Strong CAD skills (SolidWorks/Creo) with DFM/DFT knowledge
Familiarity with thermal‑management for high‑power devices
Experience supporting prototype builds and writing test protocols
Clear communication, timely delivery, and responsiveness to feedback
If you’re excited to help launch Nexer—a breakthrough in fast‑charge portability—please indicate your willingness to sign an NDA, share your portfolio, relevant experience, and estimated timeline. We look forward to collaborating! read less
