This is a builder role with a research dimension. You'll move fluidly between deep technical exploration and shipping production-grade systems, working across the off-chain and infrastructure layers that make Edge's products operable for regulated institutions — validator and staking infrastructure, custody integrations, compliance automation, and the services that sit between on-chain protocols and institutional stacks.

You own your work end-to-end: architecture, implementation, and operability. You move ideas from research and prototype through to production without losing rigour, and you're comfortable operating with high autonomy in a fast-moving environment.

Build and own off-chain systems

• →Design and build the off-chain systems and infrastructure that power Edge's on-chain products — validator and staking architectures, custody and key management integrations, compliance automation, and the APIs and services that connect institutional workflows to on-chain settlement.
• →Own deployments end-to-end: infrastructure-as-code, observability, audit logging, runbooks, and the SLAs that institutional clients depend on.
• →Take ownership of architecture and implementation, not just execution against a spec.

Research and design new systems

• →Move ideas from research and prototype through to production without losing rigor.
• →Contribute to technical research and help define the direction of new systems.
• →Engage with emerging on-chain primitives and assess how they translate into production-grade infrastructure for regulated institutions.

• Strong fundamentals in distributed systems, backend engineering, and production cloud infrastructure.
• Experience designing and operating systems with real reliability, security, and auditability requirements.
• A track record of taking ideas from prototype to production with care and rigour.
• Comfort working in a high-autonomy, fast-moving environment.
• Working knowledge of blockchain systems — Ethereum, Solana, validator operations, or on-chain protocols — or a clear track record of picking up new domains deeply and quickly.
• High agency, low ego. You own your work end-to-end and hold yourself accountable for quality.
