Senior Software Engineer, Core
You'll be designing, building, and implementing changes to Stellar Core, the primary distributed system used for maintaining Stellar's ledger and obtaining global consensus. You'll work on a wide variety of problems focused on growing and scaling the global network, including features that increase peer-to-peer networking and processing performance, decentralization and resilience to node failures or coordinated attacks, and proper incentive mechanics for network participants. You'll get to play with formal models and verification for consensus, run simulations to confirm emergent properties, and tackle typical scalability problems across distributed and multi-core systems. You'll collaborate closely with the CTO, the engineering team, and the open source community while owning core subsystems and helping the team hit critical product milestones.
