Senior Software Engineer
Confirmed on the employer's own hiring board on Sep 24, 2026. First seen by Alion on Sep 22, 2026.
Runa is pioneering a first-of-its-kind payment rail that enables the seamless, global money movement at scale. Legacy banking and payment infrastructure struggles to support the demands of today's low-volume, high-velocity payouts, leading to inefficiencies in global payouts. Businesses worldwide send over $20 trillion annually in rewards, remittances, and disbursements often incurring costs of up to 50% per transaction and subjecting recipients to lengthy delays.
Runa transforms this landscape by providing a new digital payments infrastructure that empowers businesses to send digital money instantly and cost-free to anyone, anywhere. The Runa API empowers thousands of businesses to make payments to 5 billion+ consumers in 190+ countries instantly to cards, wallets, bank accounts and gift cards. Leading companies such as Sodexo, TopCashback, Perkbox, Sweatcoin, Coinbase, and Globetopper rely on Runa to facilitate instant, flexible global payouts to tens of millions of consumers.
