Warsaw (fully remote), Poland Senior Python Backend Engineer We’re looking for Python backend engineers to work on a trustless supercluster of performance-proofed GPU-enabled sandboxed docker container runners controlled by truly decentralized algorithms (not just PAXOS or RAFT). Wow, that was a mouthful... If you found it interesting, join Reef Technologies and tackle complex technical challenges like this on your own terms: Contribute from wherever you like—we are fully remote but like to stay in sync, so we’re currently hiring in EMEA/APAC. Set your own time commitment, as long as it’s at least 30h per week See how we work in our handbook Influence the way we operate through our Sociocracy 3.0 decision-making process Salary on a B2B contract: 45-70 USD or 180-280 PLN per hour Flexible work schedule (as measured with a time tracker) We automatically adjust rates based on inflation twice a year So, what do you think? You don't even need a CV, just click here and shoot a few quick commands to apply. We're looking for someone with 5+ years of programming experience, including at least a year with Python (including opensource and significant personal projects).
