Founding Engineer

What you'll do As an early engineer, you will be tasked with owning the technical development of the Swig stack. You'll have end-to-end responsibility over the entire Swig architecture, which includes the core Swig protocol, our rust/typescript SDKs, smart contracts, identity services, and web UIs. The core Swig protocol is open source at its core. Therefore, you must be comfortable developing concurrent open source and managed services. This is a high-growth role where you'll partner closely with the CEO on product strategy, GTM, and business development. You will play a critical role in shaping the culture of our engineering organization and the company as a whole. £2,000 signing bonus paid to you on hire. Key Responsibilities Completely own the Swig stack end-to-end, which includes: the core Swig protocol, its SDKs, key services (i.e. identity provisioning), and web UIs Maintaining Swig's services, which includes coordinating audits for critical deploys and holding a strong quality bar for development quality Writing backend/client code and smart contracts for new features Acting as a key business development participant in technical conversations with potential partners Serving as the defacto engineering voice of the Swig org Being a close partner with the CEO on subsequent engineering hiring and constructing the culture of the engineering organization Success Criteria You're a full-stack IC at heart with a true player/coach mentality You have a deep sense of product craft. You maintain an ultra-high quality bar with a deep appreciation for intuitive, simple, and beautiful consumer and b2b products. You have an extreme bias for action. When you spot bugs you don't push them to the backlog or wait until a future sprint to squash them; you just fix them. You think in terms of systems, not features. You can peer far into the future. With this super power, you see how the pieces fit together and you plan accordingly for scalable services that will limit tech debt, large rewrites, and promote a culture of modularity. You're an incredible, n-of-1 verbal and written communicator. You get to the point with succinct, data-based articulation. You prioritize quick communication with your stakeholders as needed. Your default mode is to 'act as an owner'. You have a high degree of personal accountability and bias to problem solve collaboratively even if it requires working outside normal hours. When there is a problem, you attack it ferociously until it is resolved. The word 'ambiguity' fires you up. You have strong opinions, loosely held. You come to the table with a perspective, but appreciate that you may be wrong and truth-seek from first principles until a root cause is found. You believe that listening is sometimes better than speaking. You have a demonstrated history of building systems, SDKs, and dynamic infra services at scale. You're an expert in SVM/EVM (web3.js and solana sdk 2.0). You have experience managing complex zk infrastructure. You've built an integration related to money movement.
