ABOUT THE ROLE

Taktile helps financial institutions make smarter, safer decisions with the power of AI. Our software gives teams the tools to automate complex decisions, from customer onboarding and underwriting to fraud detection, with full visibility and control. By combining AI with a rich ecosystem of financial data, we enable companies to adapt their decision-making in real time as markets, customer behavior, and risks evolve.

We're looking for a Senior Full-Stack Engineer to be a founding member of the Web SDK team and help shape this product from the ground up. You'll own the architecture of a unified client-side SDK that abstracts identity verification, device intelligence, and document capture behind a single, elegant integration, used by financial institutions to onboard customers securely and seamlessly. This is a high-impact, high-ownership role with a clear path to leading the team as it grows.

If you've built SDKs, shipped embeddable components, or worked on developer-facing products that run in other people's browsers, and you're excited about doing it again at the intersection of fintech and platform engineering, we'd love to talk.

WHAT YOU'LL DO

- Architect the SDK from scratch: Design and build a client-side JavaScript/TypeScript SDK that orchestrates multiple third-party vendor scripts behind a unified, headless API.

- Build the hosted verification experience: Create a secure, embeddable web application that renders interactive identity verification flows with a polished, brandable UX.

- Own reliability end-to-end: Establish versioning strategies, staged rollouts, and CI/CD pipelines for client-side code that runs in customer browsers.

- Solve hard integration problems: Wrangle vendor SDKs that each have their own quirks, lifecycle hooks, and failure modes, and make them work together seamlessly.

- Shape the product and the team: Collaborate with Product, Design, and customers to define the SDK's developer experience. As the team...
