What you will do

Design schemas and write safe D1 migrations for live data — the system already has close to 200 of them.
Tune queries, indexes and read/write volume to keep latency low and costs predictable.
Build background jobs on Cloudflare Queues and Workflows — metric syncs, publishing, long-running AI tasks — with retries and de-duplication.
Sync data from Meta, Google Ads, GA4, Search Console, TikTok and online store platforms.
Own backups, point-in-time recovery and the database's resilience to transient errors.
Write tests for queries and data edge cases.

2+ years of backend development; strong SQL and relational data modelling.
You understand transactions, consistency, idempotency and duplicate handling in distributed systems.
Experience with queues or background jobs (Queues, SQS, RabbitMQ, BullMQ…).
TypeScript/JavaScript, or willingness to switch from another language.

Working hours: Office hours; your exact schedule is agreed at interview.
Location: Ho Chi Minh City, Vietnam — the exact office address is sent with your interview invitation.

Your contact details and a few lines about yourself (required). A CV is optional — if you have one, attach a PDF, DOC, DOCX, JPG or PNG up to 10 MB.
A link to your GitHub, portfolio or something you have built — one real project says more than a page of CV.
If you can: measurable results from your work (revenue, customers looked after, campaigns, articles) — add them to your introduction.
Degrees and certificates (if any) — only needed when you join, no need to send them in advance.
SOZO never charges candidates any fee and never asks for photos of your ID over social media.
