Job Description: What You’ll Do:

As a Senior Software Engineer, you’ll take the lead in building high-quality front-end experiences that power our strategic philanthropy and life sciences platform. While much of your focus will be on React, Next.js, and modern front-end development, you’ll also collaborate across legacy and full-stack systems where needed to ensure seamless user experiences. This role is ideal for someone who combines strong UI development skills with pragmatic engineering judgment and who’s comfortable navigating both new and existing codebases to drive impact.

Design and build high-quality front-end experiences: Use technologies like JavaScript, React, Next.js, and CSS to deliver intuitive, performant interfaces that make complex workflows feel simple. 
Participate in code reviews and architectural discussions: Help shape best practices around front-end engineering, accessibility, performance, and maintainability. 
Collaborate Across Disciplines: Partner with product managers, designers, QA engineers, and other developers to build intuitive features that meet user needs and align with our mission. 
Use AI as a Force Multiplier: Accelerate development with tools like Cursor while relying on solid engineering fundamentals to efficiently produce high-quality, maintainable code. We see AI as an assistant—not a substitute—for thoughtful, experienced engineers. 
Raise the Bar on How We Work: Participate in code reviews, knowledge-sharing, and technical discussions while modeling best practices. Help pioneer and refine evolving team processes, and play a key role in shaping how we work as our tools and technologies advance. 
Contribute to Company Culture: Embody our values by approaching your work with empathy, curiosity, and accountability. We’re looking for teammates who elevate others, embrace inclusive collaboration, and aren’t afraid to take smart risks in pursuit of bold, mission-driven outcomes. 

Who You Are: 

You’re a front-end-focused senior engineer who cares deeply about crafting intuitive, performant user experiences. You bring deep experience with React and CSS, and you know how to navigate complex systems, whether modern, legacy, or somewhere in between. You’re not afraid to get your hands dirty in unfamiliar code or to question assumptions when something feels off. You balance strong technical instincts with humility and a team-first mindset.

You’re excited by the possibilities of AI-assisted development and know how to use these tools to boost productivity, not bypass thoughtful engineering. You contribute actively to team discussions, enjoy giving and receiving feedback, and look for ways to make both the product and the team better every day.

You bring:

Advanced proficiency in React, Next.js, CSS, and modern JavaScript/TypeScript frameworks. 
A strong eye for UI quality, including accessibility, performance, and maintainability. 
Comfort navigating backend or full-stack systems to unblock your work or support integration. 
Hands-on experience or strong interest in using AI-enhanced development tools like Cursor, and openness to experimenting with new workflows in an AI-first engineering environment. 
A collaborative, inclusive mindset with a commitment to helping others grow through code reviews and shared problem-solving. 
Excellent written and verbal communication skills with the ability to present complex technical information in a clear and concise manner to a variety of audiences.
