Staff Software Engineer: Perpetuals

Responsibilities

• As a Staff Software Engineer, you will
• Own the technical architecture and roadmap for MetaMask's Perpetuals experience across Extension and Mobile — from real-time price/position data flows to order execution and margin/liquidation UX.
• Set technical direction and standards for trading-critical features: precision/decimal handling, state consistency under high-frequency updates, and resilience to feed/connectivity failures.
• Drive cross-team technical alignment with other experience teams and backend/protocol integration teams to ship complex, multi-team projects.
• Identify and de-risk the hardest technical problems on the roadmap before they become blockers; make build-vs-buy and architecture trade-off calls for the domain.
• Partner with the Engineering Manager on prioritization, providing the technical judgment that shapes what gets built and in what order.
• Mentor senior and mid-level engineers, run design/architecture reviews, and raise the technical bar through example, documentation, and code review.
• Represent Perpetuals engineering in cross-functional planning with Product
• Design, and other engineering leads.
