Remote GPU Backend Engineer - Lemon.io Global — Columbus
Traveler-Friendly Insight
Location Freedom: This is a fully remote, full-time contract role sourced through Lemon.io, with talent accepted from 75+ countries across Europe, LATAM, North America, Asia, Oceania, and Africa. That's about as geo-flexible as it gets for senior engineering work.
Async vs. Sync: The posting emphasizes delivering "without supervision" and owning problems end-to-end — strong signals of an async-friendly culture. However, client calls are mentioned explicitly ("present yourself and results well on client calls"), so expect some overlap hours with US/European time zones. Aim to have at least 4 hours of daily availability during CET or ET business hours.
Visa Considerations: Since this is a contractor/freelance arrangement (not direct hire), you can work from virtually anywhere on a tourist or digital nomad visa. Popular options include Portugal's Digital Nomad Visa (D8), Mexico's temporary resident permit, or Thailand's LTR Visa — all compatible with contractor income.
Cost of Living vs. Contractor Rates: No salary is disclosed, but senior Golang/Python engineers on platforms like Lemon.io typically earn $80–$130/hr equivalent on an annual basis. That income goes far in Medellín (avg. ~$1,500/mo living costs), Lisbon (~$2,200/mo), or Bangkok (~$1,200/mo).
- No visa sponsorship provided — plan your own legal work status.
- No equipment stipend or coworking allowance mentioned.
- Contractor model means no traditional employment benefits.
Lemon.io helps companies in the US and Europe hire experienced engineers, from funded startups to teams like Klarna, Retool, and Pinterest. We've been doing this since 2015, and more than 1,500 companies have hired engineers through us.
Currently, we have a few open positions from our client, an AI-native cloud company. AI teams use its platform to run inference on open-source models, fine-tune them, and rent large GPU clusters. The fleet is set to grow about 10×; the team won't. That's where you come in.
