About the role

As a Full-Stack Engineer at Lumi, you will be an important part of our small and dynamic team, working on a wide variety of projects, from customer-facing features to internal tools. We strive to write elegant code to solve real-world problems. This job is open to remote applicants within the US.

We use Haskell and Postgres on the backend and ES6/React with an increasing amount of PureScript on the front-end. On the Haskell side, we primarily use servant and esqueleto, and Stack as our build tool. We get an enormous amount of utility from all aspects of Haskell's type system, from the most basic features like newtypes and sum types, to type families and GADTs.

Among many other projects, your work could include adding new features to the Lumi app, building internal tools and integrations, building our library of reusable UI components, building public APIs, etc.


While you don't need to have intimate knowledge of every tool in our stack, you should be proficient in at least one of Haskell, Postgres, PureScript or ES6/React, and have enough fundamental skills to find your way around the rest. For example, you might not know how to manage a production Postgres database, but you should be able to log in and execute some basic queries.

  • You should be comfortable working remotely and with minimal supervision.
  • You should be able to manage your development projects from start to finish, from planning and time estimation, through development and testing, to documentation and deployment.
  • You should be able to work with non-technical members of staff to gather and distill project requirements.
  • Some knowledge of any of the following areas is preferred: continuous delivery, statistical analysis and machine learning, database administration, security best practices
  • If you have contributed to open source projects, share that with us!


  • Stock options
  • Competitive salary
  • Paid time off
  • Healthcare plan
  • SIMPLE IRA retirement plan
  • Laptop or desktop computer
  • Company events and happy hours
