Waybridge, backed by Ergonia, is building an institutional borrow / lend protocol on Canton Network. We have an operational mainnet validator, existing smart contract code, and active counterparty relationships with institutional participants. We are looking for a CTO/Technical Lead to take ownership of the protocol architecture, inherit and evolve our existing codebase from an external dev shop, and build the engineering team as the company scales. The Role This is a co-builder position. You will own the full technical surface of a financial protocol: from DAML smart contracts on a distributed ledger, through the backend settlement and accounting layer, to the institutional-grade frontend dashboards. You are equally comfortable auditing inherited code, designing a new module, and closing a senior engineer hire. The four pillars below define what we need. Responsibilities: 1. Financial System Architecture 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 2. Fullstack Engineering (NestJS + Next.js) Our stack is NestJS on the backend, a Rust indexer for ledger events, and React/Next.js on the frontend. You will inherit an existing codebase from an external dev shop and decide what to keep, refactor, or rebuild. - Audit the inherited backend and frontend codebase; determine the refactor-vs-rewrite strategy - Own the backend services layer: RESTful APIs, settlement engine, accounting services, WebSocket feeds - Extend and optimize the Rust indexer for new on-chain event types - Guide frontend architecture for data-dense institutional dashboards (portfolio views, real-time position tracking, yield analytics) - Establish CI/CD, testing standards, and code quality practices across the full stack 3. Smart Contract Architecture (DAML / Canton) The protocol layer runs on DAML, a Haskell-based smart contract language on Canton Network. DAML experience is extremely rare and not required, but direct experience is a major plus. What matters is strong functional programming instincts and the ability to ramp quickly. A production Haskell or Scala engineer can be writing DAML in weeks. - Lead DAML smart contract design for lending and staking modules - Define on-chain vs. off-chain boundaries: what the smart contract enforces vs. what the backend handles - Collaborate with Canton ecosystem partners on staking protocol design and network-level integration - Bring strong functional programming depth (Haskell, Scala) and apply it to contract modeling, type safety, and state machine correctness. 4. Small Team Management 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
