Founding Engineer : SWIG

Swig is building the future of onchain wallets.

Swig is a smart wallet-as-a-service platform that radically simplifies how developers and users interact with blockchains. Built from first principles for an onchain world, Swig combines account abstraction, granular permissions, and flexible identity attestation into a native wallet architecture—no centralized infrastructure, no hidden trade-offs.

Where legacy wallet providers rely on off-chain systems, Swig puts core logic onchain by default, ensuring composability, resilience, and trustless design at every layer. Features like multi-wallet delegation, session keys, and automated transactions come baked in—making powerful wallet experiences easy to build and seamless to use.

Swig gives developers the tools to build secure, flexible wallets that feel simple and intuitive—without sacrificing control. We believe wallets should be invisible until they matter. Swig is how we get there.

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.

• 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

• 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 are 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 are an expert in SVM/EVM (web3.js and solana sdk 2.0)

• You have experience managing complex zk infrastrucutre

• You’ve built an integration related to money movement. You have expertise in funds ledgering, settlement, and recons.

• Must-have proficiencies: rust, typescript, react, next.js, node.js, typescript, css, shell

• You have prior direct management experience
