Go Backend Developer at Webbing - Fully Remote Romania — Columbus
Traveler-Friendly Insight
Remote-Friendly Setup: This role is explicitly fully remote, making it a solid option for digital nomads based in or eligible to work from Romania. While the job posting doesn't specify required timezone hours, the mention of pair programming with a Senior Developer suggests some overlap with a core working window — likely CET/EET (UTC+1/+2), which is common for European-based companies like Webbing.
Timezone Considerations: Romania operates on EET (UTC+2), so nomads in nearby zones — Southern Europe, Eastern Africa, or the Middle East — would face minimal schedule friction. Those in Southeast Asia (UTC+7 to +8) would need early morning availability, which may be challenging for synchronous pairing sessions.
Visa & Location Notes: The role is restricted to Romania based on the location hint, so non-EU nationals should research Romania's digital nomad visa options. Romania has a digital nomad visa program allowing stays of up to 1 year for qualifying remote workers.
Nomad Cost-of-Living Snapshot: No salary is disclosed, but Go backend developers in Romania typically earn €1,500–€3,500/month. This stretches well in popular nomad hubs:
- Bucharest, Romania: ~€800–€1,200/month living costs — very affordable locally.
- Lisbon, Portugal: ~€1,800–€2,500/month — feasible at mid-to-upper salary range.
- Bangkok, Thailand: ~€900–€1,400/month — comfortable if timezone overlap is manageable.

- Build the Inventory Management Database: tables, indexes, partitioning for 30M records.
- Build bulk import tooling: CSV → ICCID/IMSI/MSISDN range ingestion from vendor.
- Implement REST API endpoints for Inventory DB (allocate, reserve, release, query SIM records).
- Write integration tests: workflow → mock NE → database assertions.
- Support Sr. Developer on all workflow development tasks — pair programming expected.
