Associated Electric Cooperative 4.3
Staff software engineer job in Springfield, MO
At Associated Electric Cooperative, we're committed to providing reliable energy to the communities we serve with passion and precision. We're a tight-knit team dedicated to keeping the lights on and the energy flowing smoothly across our expansive network!
From technical to operational to professional disciplines, our team brings a wide variety of skills, talents, and expertise to the table. We believe in both dedicating ourselves to excellence and investing in your growth.
Be part of building the tech that maintains the largest machine on earth-the U.S. power grid. Associated Electric owns and operates a fleet of power plants powering homes across the Midwest, and we're building a new product that will become the backbone of how Associated Electric Cooperative manages those power plants. This product will become the digital twin of our entire power plant fleet - used across the organization, from the plant floor to company leadership - giving everyone a shared, data-driven view of plant health and performance. It will unite asset data, financials, and strategic plans into one integrated platform that aligns daily operations with long-term strategy.
To build this product, we need you - a softwareengineer with a track record of delivering cloud-native, data-centric, visually-rich enterprise applications that feel as polished as the best consumer software. This isn't a gray-background, form-and-grid enterprise app - it's an experience that can sit confidently next to products from Microsoft or Apple. You'll design and build a tool that handles enterprise complexity - high data density, workflows, integrations, multi-stakeholder needs - while staying intuitive, fast, and elegant for the people who use it. You'll join at the ground floor, shape the product, and work side-by-side with business stakeholders, data engineers, and UX designers to create something that matters - a product that changes the game for its users, drives bottom-line impact for the company, and becomes a lighthouse example for the industry.
You and your team won't be starting from scratch - the team already has full product management ownership of an ecosystem of power production technology systems that will integrate with this new product. Some are third-party systems, like our newly modernized enterprise asset management platform, and others are smaller 3rd or first-party tools that may be modernized or replaced as the new product the team is building comes online. Being part of supporting and evolving this ecosystem means that you'll have ample opportunity to know your users, run and improve the current systems, and chart the future for each product in a world where the digital twin becomes the hub of plant management.
What you'll do:
Own the Product: Design and develop the web application that is the face of the digital twin - turning data, models, and insights into intuitive, powerful user experiences for plant staff, engineers, leaders, and executives.
Fuse the Enterprise: Design and build the integrations and data, workflows, and experiences that integrate asset-level predictive models with financial, work management, and operational data to create a true fleet-wide picture of health, risk, and performance.
Build for the Users: Champion the people who rely on this product - from plant floor staff to executives. Relentlessly look for better ways to capture, model, and deliver insights, and connect them to the information they need to make faster, smarter decisions.
Ship! Ship! Ship! Work with PM, UX, tech engineers, and expert stakeholders to turn workflows, data, and models into a web app that users can't wait to adopt. Champion design, value, and quality so every release makes the product stronger.
How we build:
You'll work in a small, empowered agile product team with a dedicated Product Manager (your direct lead), UX designer, softwareengineers, and analysts - shipping fast, learning fast, and building toward a bigger vision. You'll collaborate daily to turn data and models into a web-based product that delights users, while iterating closely with plant staff and executives to ensure it works in the real world. You'll build on a cloud-first Microsoft stack - C#, Visual Studio, Azure, Databricks, etc… Importantly, you'll have leadership support and a mandate to deliver something that makes a lasting difference.
What you'll need:
Education & Core Skills: A bachelor's degree in Computer Science, SoftwareEngineering, STEM, or equivalent experience, with a strong foundation in cloud-native application development.
Modern SoftwareEngineering Experience: Proficiency in building desktop web apps with frameworks such as React, Angular, or Blazor, backed by RESTful APIs and cloud services (Azure preferred).
Data Integration Skills: Experience working with APIs, event streams, and data services to connect applications with data platforms like Databricks, SQL databases, and NoSQL stores.
UI/UX Implementation: Ability to translate design mockups and wireframes into fast, responsive, and accessible interfaces, with an eye for clarity and usability for expert users. An ability to “dance” with an UI specialist to improve their designs with your experience.
Software Craftsmanship: Strong skills in testing, CI/CD pipelines, version control (Git), and code review - focused on building robust, maintainable solutions.
Business Mindset: Ability to understand business processes, see the “why” behind requirements, and shape solutions that improve how the business runs - connecting technical decisions to business value.
Collaboration & Influence: Excellent communication skills, comfortable working cross-functionally with data engineers, UX designers, and business stakeholders to deliver value quickly.
What Associated provides:
We are committed to rewarding talent with top pay. Your efforts will be recognized with a total compensation package that reflects your experience and contributions.
Plan for your future with confidence! We offer a robust 401(k) program with a generous employer match to help you build the financial future you deserve.
We know how important work-life integration is. Recharge with PTO and enjoy paid holidays, ensuring you have time to unwind and pursue your passions outside of work.
Your health matters to us! Stay covered beginning on your first day of employment with our premier healthcare plan that includes medical, dental, and vision coverage for you and your family.
At Associated Electric Cooperative, all of our 700+ employees across MO/AR/OK territory play a crucial role in powering our mission!
