📋 Description

• Swan is seeking an ownership-driven Software Engineer that enjoys working from idea to implementation. You will build and extend internal and customer-facing dashboards that unify market data, on-chain analytics, and Swan’s proprietary metrics. • You will be part of the larger Swan engineering team but work independently on various stand alone wealth platform and institutional products ranging from portfolio modeling to market analytics. Expect to work end-to-end: data ingestion, API design, backend services, and polished UIs. • Compensation for this role will be based on location and experience, and may include base salary, equity, and benefits.

🎯 Requirements

• 5+ years of professional software development, with at least 2 years building data-rich dashboards for fintech or similar. • Strong backend skills: TypeScript/Node.js (preferred) or similar, SQL, data modeling, REST and GraphQL APIs. • Modern frontend expertise: React + Next.js (or equivalent), component libraries, data-viz frameworks, responsive design. • Deep commitment to clean architecture, automated testing, and clear documentation. • Self-driven and well organized in project and product management. Able to take complex projects from idea to completion with minimal guidance. • Excellent asynchronous communication in a high bandwidth remote environment. • A basic understanding of financial data, Bitcoin blockchain analytics, equities, Bitcoin treasury companies, and capital markets is a plus, but not required. • Adept with modern AI tooling and ready to deliver quickly. • US timezones only.

🏖️ Benefits

• We’re a growing team: Fully distributed across the world, Slack and Huddles are huge here. • We’re very flat: Leadership is desired and encouraged; we hire people who care about and use the product they are working on. • We’re Bitcoiners: We find solutions that encourage Bitcoin principles. We are often involved in the Bitcoin community through writing, podcasts, conferences, open-source projects, and time spent on Twitter to help educate the masses. We love Bitcoin, and it comes through in our daily chats, meetings, and actions.
