Founding Engineer and Tech Co-Founder
Siphon is building confidential execution infrastructure for on-chain finance.
Funding history
About Siphon Money
Public blockchains expose transaction intent before execution, creating opportunities for front-running, sandwiching, strategy replication and other forms of value leakage. Siphon provides protocols with a private execution layer for strategies such as limit orders, stop-loss, DCA, TWAP and grid execution — delivered through an API and SDK rather than requiring each integrator to build its own privacy infrastructure. Our stack combines confidential computation, zero-knowledge systems and trusted execution environments while settling against public on-chain liquidity. The goal is to make private execution a composable piece of financial infrastructure that DEXs, aggregators, wallets and agent-based systems can integrate directly. #
Skills
About the Role
You will own and evolve confidential execution architecture across zero-knowledge components TEE infrastructure relayers and Solidity settlement contracts. You will take the system from alpha to production while improving security reliability and performance. You will build partner-facing SDK API and MCP interfaces support protocol integrations expand to additional EVM networks and establish engineering standards for testing observability incident response and code review. You will also work with auditors and technical partners and participate in technical hiring.
