Job Summary
Responsibilities:
📍Waybridge is a financial protocol, not a typical web app. Every data model, state transition, and API must be designed with the rigor of a system that manages real institutional positions. 📍Design and own the position lifecycle engine: origination, funding, accrual, partial repayment, recall, and closure 📍Architect a shared accounting layer that serves multiple lending modules 📍Model settlement flows, collateral custody, yield attribution, and reconciliation for bilateral agreements 📍Ensure correctness guarantees throughout: idempotency, audit trails, and immutable state history
You will hire and lead a team of 2-4 engineers. This is not a management-layer role where you delegate and review. You are hands-on, writing code daily, while also recruiting, unblocking, and setting technical direction.
📍Hire a Senior Backend Engineer and a Senior Frontend Engineer in the first 4-6 weeks 📍Manage knowledge transfer from the existing external dev shop to your in-house team 📍Run sprint planning and translate product requirements into engineering execution 📍Partner directly with the CEO on product-to-engineering decisions, sequencing, and tradeoffs 📍8+ years in fullstack or backend engineering, with at least 2-3 years in a technical lead or architect role 📍Production functional programming experience (Haskell, Scala, OCaml, or equivalent) 📍Background in financial services, fintech, or high-growth startups building systems with correctness requirements
The future of finance is here — whether you’re interested in blockchain, cryptocurrency, or remote web3 jobs, there’s a perfect role waiting for you.
