Software Engineer III

MISO is hiring a Software Engineer III. You’ll take a hands-on role in building

reliable, scalable systems that keep our grid running smoothly. You’ll design

and develop software from the ground up, enhance existing applications, dive

into code reviews, and help drive high‑quality engineering practices. If you

enjoy working across the full development lifecycle and want to contribute to

meaningful, real‑world impact, you’ll feel right at home here.

Why Join MISO?

* Contribute to the engineering behind MISO’s $10B capacity market by building

and modernizing interconnected systems, ensuring regulatory compliance, data

accuracy, and reliable integrations across the Resource Adequacy domain.

* Apply and advance AI‑native engineering practices while using strong Java

expertise to deliver high‑value solutions in a complex, mission‑critical

environment.

* Work on real-world projects that impact the power industry and ensure energy

reliability.

* Be part of a strong, collaborative engineering culture across MISO’s

locations, where software professionals solve meaningful technical and

industry challenges.

* Collaborate with experienced product owners, architects, system engineers,

support professionals, and other software engineers, influencing all aspects

of the Software Development Lifecycle (SDLC).

Your Responsibilities as our Software Engineer III include:

* Design, build, test, deploy, operate, and modernize reliable Java/Spring Boot

applications in data-intensive, mission-critical, and compliance-driven

environments, including legacy systems, APIs, databases, cloud and container

platforms, automated testing, and CI/CD.

* Determine the technical approach for complex features, accounting for

functional and non-functional requirements such as security, reliability,

performance, maintainability, data integrity, and operability.

* Serve as the technical lead for assigned features by refining requirements

and acceptance criteria, estimating complex work, coordinating

implementation, and supporting successful deployment and release.

* Partner within cross-functional product teams including engineering, product

management, architecture, business subject-matter experts, data teams, and

external partners to clarify evolving requirements, evaluate technical

tradeoffs, and move valuable work forward.

* Apply generative AI throughout the software development lifecycle including

design, implementation, testing, code review, documentation, and

troubleshooting to accelerate delivery and improve quality.
