Chaincode Labs, located in New York City, contributes extensively to open-source software, coordinates development efforts across the broader open-source ecosystem, supports the training and mentorship of new engineers, conducts original research, and develops implementations of novel systems and ideas. The organization is well funded and well staffed, with the capacity to produce production-quality software and provide critical infrastructure support. Applicants should be currently pursuing a PhD degree or engaged in postdoctoral research. The internship duration will be between two and three months, depending on candidate's availability and the scope of the proposed research project.

Partners include Brink, Summer of Bitcoin, Btrust Builders. - **Growth Signals**: - Team operates across 5 countries (US, Spain, Italy, Morocco, Canada) – distributed by design. - LinkedIn reports 1,450 followers (+20.6% YoY) and a 5.0/5.0 employer rating (1 review). - Continued publication of Bitcoin Core improvements and Lightning spec work; new contributions from residency alumni. ## Competitive Advantages - **Deep Bitcoin Focus**: Entirely dedicated to Bitcoin and Lightning; no altcoin or commercial distractions. - **Core Contributors on Staff**: Includes Pieter Wuille (co-creator of SegWit, BIPs), Carla Kirk-Cohen (Lightning spec), Antoine Poinsot (Bitcoin Core, security), and other long-time Bitcoin Core contributors. - **Proven Alumni Network**: Many residency alumni go on to leadership roles at other Bitcoin companies (Brink, Lightning Labs, Btrust) or continue contributing independently. - **Founder Stability**: Privately funded by founders with deep pockets from Hudson River Trading – no pressure to monetize or pivot. ## Strategic Focus - **Current priorities**: Improving Bitcoin Core performance, security, and code separation (node/wallet/GUI); advancing the Lightning Network P2P layer; onboarding new developers through the residency program and open-source mentorship. - **Direction for growth**: Sustaining long-term R&D on Bitcoin and Lightning while expanding educational reach (grants, scholarships, and possibly more remote residency slots). ## Why Work Here - **Culture**: Highly mission-driven, research-oriented, and collaborative. Focus on code quality, open-source ethos, and intellectual freedom. - **Remote/Hybrid Policy**: Distributed team across time zones; likely remote-friendly (LinkedIn shows offices in New York, but team spans multiple countries). Specific policy not publicly detailed. - **Notable Perks**: - Work on the world’s most decentralized cryptocurrency alongside pioneers. - Paid open-source contributions with no sales or product deadlines. - History of high code impact – many merged BIPs and Core commits. - **Engineering Culture**: Emphasis on safe, welcoming learning environments (per operations staff); includes regular talks, pair programming, and review culture. ## Sources 1.
