Platform Engineer

We’re hiring a Platform Engineer to help world-class financial institutions automate away their backoffice. This is a hands-on role for an engineer who loves building reliable, elegant backend systems that make complex business processes feel simple. You’ll work on the heart of our platform — APIs, data models, and integration layers — ensuring everything we ship is fast, secure, consistent, and easy to extend.

You’ll collaborate closely with our founder and product engineers to design scalable backend architecture, bring new services online, and integrate third-party systems securely and efficiently. You’ll have ownership over technical direction and see your work have a direct impact on the company’s success.

The ideal candidate is pragmatic, systems-minded, and takes pride in creating clean abstractions and resilient automation. You care deeply about developer velocity, observability, and security, and you’re not afraid to make tradeoffs to achieve real-world reliability. You move fast, think clearly, and bring both architectural depth and a builder’s mindset.

Eisen is based in New York City, and in-person collaboration is preferred.
