Senior Backend Engineer - Risk Infrastructure

SF, NY, Portland, or remote in US/Canada

We launched about four years ago with basic functionality, and now we’re refining our product and building out new features. Thankfully, our customers seem to like what we’ve built so far:

I tested the Mercury drag and drop Bill Payments, and I love it. Would you marry me, Mercury?


Introducing: Bill Payments. When paying someone on Mercury, you can now drag & drop bills directly onto a payments page. We’ll scan each document and automatically populate different fields — so you can spend less time on your accounts payable & more time running your startup.


Technically, we’re working on these challenges:

  • Frontend — React, Typescript, Redux: Creating a beautiful user interface. We iterate on designs and don’t compromise until we have a great product.
  • Backend — Haskell, Yesod, Persistent: Integrating with services and third party APIs to accurately track financial data and make payments.
  • Operations — Nix, Postgres, AWS: Maintaining a stable, secure fleet of servers.
  • Mobile — Swift, Kotlin: We have native iOS and Android apps.

The Risk Infrastructure team supports Mercury by building essential tooling and software infrastructure to ensure that we can manage compliance and fraud risk across all areas of our business. Today, we’re furthering that mission by building a Decision Engine - a tool that allows our internal users to write, test, and safely deploy and run policies while getting monitoring, testing, and auditability by default.

As a backend engineer on the Risk Infrastructure team, you’ll do things like:

  • Add and enhance features and improve the developer UX of the Decision Engine Core library
  • Work across all areas of the Mercury product to expand coverage of risk infrastructure systems
  • Collaborate with domain experts in risk and compliance to write and deploy new features and rules
  • Spend time troubleshooting and optimizing queries to ensure they run quickly and correctly
  • Build and support new ways for our Risk Operations team to apply or remove friction from customer transactions

The ideal candidate has demonstrated experience working at the senior level or higher with a focus on full-stack or backend engineering. We’re looking for someone that is interested in learning Haskell and is comfortable working in SQL.
