Core Protocol Engineer at Ritual - Remote Worldwide — Columbus
Traveler-Friendly Insight
Location Flexibility: Ritual is fully remote with no stated geographic restrictions — "Anywhere in the World" means this role is open to digital nomads wherever they base themselves. No specific timezone is mandated in the posting, which is a strong signal for async-friendly work. That said, a "high-pressure, fast-paced" environment with context-switching demands suggests some real-time availability during core hours may be expected in practice.
Visa Considerations: Because the role is open globally, a wide range of nomad visa options apply:
- Portugal (Lisbon): Digital Nomad Visa (D8) or NHR tax regime; salaries in this field typically cover Lisbon's cost of living very comfortably (~$2,500–$3,500/month).
- Thailand (Chiang Mai/Bangkok): Long-Term Resident (LTR) visa or tourist visa runs; monthly living costs of ~$1,200–$2,000 make this a high-savings destination for a senior Web3 engineer salary.
- Colombia (Medellín): Digital nomad visa (Migrant-V) or tourist stay up to 180 days/year; cost of living ~$1,500–$2,500/month.
Travel-Relevant Perks: No explicit coworking stipend or equipment budget is mentioned, but "top 1% of benefits" and the mention of virtual and in-person events suggest company-covered meetups may offset some travel costs. The 401(k) match is US-centric — confirm applicability for non-US contractors.
