Product Applications ​
Engineers must apply and be approved to work on different product types. Each product requires specific qualifications, certifications, and documents. The application process ensures engineers are properly qualified before receiving job assignments.
How it works ​
- Browse products - Engineers view available products in the Products section of their profile
- Check requirements - Each product shows required documents and estimated completion time
- Start application - Begin the application process by uploading documents and completing forms
- Submit for review - Once all requirements are met, submit the application for review
- Await approval - Applications are reviewed by the Zuno team and approved, rejected, or paused

Application statuses ​
Applications progress through the following statuses:
| Status | Display | Description |
|---|---|---|
missing | "Apply" | Engineer has not started the application |
started | "In progress" | Application started but not submitted |
pendingReview | "Pending - in review" | Submitted and awaiting review |
approved | "Approved" | Application approved, engineer can receive jobs |
rejected | "Rejected" | Application denied |
paused | "Jobs paused" | Jobs temporarily suspended (usually due to expired documents) |
comingSoon | "Coming Soon" | Product not yet available for applications |
Document status tracking ​
For approved applications, the system tracks document expiry dates:
| Document Status | Description |
|---|---|
upToDate | All documents are valid |
docsExpiring | Documents will expire soon (warning shown) |
docsExpired | Documents have expired, jobs may be paused |
Prerequisites (two-step applications) ​
Some products require approval on a prerequisite product first:
Electrical ──► EV Chargers
└─► Solar & Battery
Boiler ──────► Heat PumpsWhen starting an application with prerequisites:
- The system checks if the prerequisite is approved
- If not approved, the engineer is redirected to the prerequisite's application first
- After prerequisite approval, the engineer can complete the dependent application
