Here, you will find a culture guided by inclusion, talented peers, comprehensive benefits and career development opportunities.

Position Summary:

As Senior Software Engineer, Product, you'll report to the Senior Director leading ACT (Accelerated Core Technology) and be the team's builder-in-chief for user-facing products. You'll turn rough concepts into polished, working apps and sites fast - sweating the craft and the details without losing speed. If you're a motivated problem solver who's energized by ambiguity and wants your work seen and used by real people at one of the largest health care companies in the world, this is your opportunity to drive rapid, enterprise-wide innovation.

Primary Responsibilities:

Design, build, and ship high-quality mobile apps and web experiences end-to-end - from concept to a working product users can test

Build cross-platform mobile apps in React Native (primarily iOS, with some Android) and responsive, performant websites

Move fast through rapid prototyping and iteration, translating ambiguous ideas into testable experiences and refining them based on real user feedback

Own front-end architecture decisions - component systems, state management, performance, and craft.

Integrate AI/ML capabilities and APIs into products to bring new ideas to life

Partner closely with the team's engineers and downstream product/engineering teams to package and hand off proven concepts for production scaling

Set a high bar for visual quality, polish, and usability across everything the team ships

Make pragmatic build-vs-buy and good-enough-for-now calls appropriate to a POC and demo environment

Use enterprise-approved AI tools to streamline workflows, automate tasks, and drive continuous improvement

Design, develop, and deploy AI-powered solutions to address complex business challenges with an emphasis on responsible use of AI

You'll be rewarded and recognized for your performance in an environment that will challenge you and give you clear direction on what it takes to succeed in your role as well as provide development for other roles you may be interested in.

Required Qualifications

Bachelor's degree in Computer Science, Engineering, or 4+ years of software engineering experience

5+ years of experience building and shipping production mobile apps and/or web applications

2+ years hands-on experience building cross-platform mobile apps with React Native

2+ years of proficiency with modern front-end web frameworks and languages (such as React and TypeScript/JavaScript)

A portfolio, app store links, GitHub, or other viewable examples of products you have built (must be included or referenced in the resume)

Demonstrated ability to work quickly in ambiguous, fast-paced environments where requirements are not fully defined

Preferred Qualifications

Experience integrating AI/ML capabilities, LLMs, or AI APIs into user-facing products

Experience taking products from concept to launch, including front-end architecture and design decisions

Full-stack development experience and comfort working across the stack to deliver end-to-end features

Experience with React Native alongside native iOS (Swift) and/or Android development

Strong visual craft and motion/interaction design sensibility, including design systems

Background working in a startup, R&D lab, or other fast-paced, rapid-build environment

Experience in the U.S. healthcare industry or another highly regulated, complex enterprise environment

At UnitedHealth Group, our mission is to help people live healthier lives and make the health system work better for everyone. We believe everyone-of every race, gender, sexuality, age, location, and income-deserves the opportunity to live their healthiest life. Today, however, there are still far too many barriers to good health which are disproportionately experienced by people of color, historically marginalized groups, and those with lower incomes.
