CI/Build Engineer - Cardano DApps

IO Global is seeking a Continuous Integration/Build Engineer to join its DApps division. The Cardano DApps division brings distributed applications to the platform, with teams working on compiler technology, application framework support, and the Marlowe financial domain-specific language (DSL). These teams work in Haskell and PureScript, and manage multiple compiler toolchains, static analysis systems, and deployments. This is an exciting and rapidly growing set of teams with diverse needs, and keeping them moving smoothly requires a lot of attention.

As CI/Build Engineer you will be responsible for the teams’ Nix-based CI setup, manage Haskell and PureScript tooling, and assist the DevOps team with deployments by interfacing with the Nix setup.

You will also help the DevX team improve the tools used by IOG (such as with the performance of Cabal, fixing bugs in the Haskell Language Server, and occasional patches for the Glasgow Haskell Compiler, or GHC).

Your mission

As a CI/Build Engineer you will ensure that the development teams are happy, effective, and productive. This task involves creating, configuring, and using tools and frameworks to make development easier, from writing the software to deployment. You will work closely with the developers, the QA managers, and the DevOps team to define, improve, and maintain the software delivery process.

Duties will include:

• Creating, maintaining, documenting, and optimizing automated build processes
• Creating and maintaining internal tools to support development or build workflows, including advanced systems to improve build and development processes across the organization
• Working with the development team to set up and maintain a development build environment that is functional and effective
• Supporting the QA team in the definition of continuous testing processes and validation pipelines
• Fixing software bugs in compilers, build systems and operating systems
• Helping other teams with their day-to-day tools and compiling the challenges they face
• Documenting best practices
• Helping to coordinate changes with upstream.

Requirements

Your expertise

• Degree or above in computer science, computer engineering, or engineering
• Excellent knowledge of Nix and Haskell
