About The Position

One North is a digital experience agency that combines curiosity, scale, and agility to shape the future. As part of TEKsystems, a leading provider of business and technology services, we offer boutique solutions to solve complex problems. Our multidisciplinary teams of strategists, designers, and technologists excel in research and discovery, experience strategy, design, experience management, and technology implementation. Whether clients are establishing a vision for an experience or optimizing an existing one, we help businesses understand their audiences, design experiences, maximize technology, and bring their digital ideas to life. The world’s most successful companies rely on us to forge the future through electrifying work that sparks innovation and drives results. Bring your technical expertise, passion, and curiosity to a creative and energetic team that builds innovative digital experiences for our clients. As a Senior Front-End Developer, you'll work closely with every part of One North. You'll partner with industry-leading strategists and designers, build alongside architects and developers, and help shape the work from kickoff to launch. In an increasingly competitive digital market, our developers are given the space to invent, problem solve, explore, fix, and create. As a Figma Service Partner, we work deeply within the Figma ecosystem, from early design exploration through production handoff and design system management. The Senior Front-End Developer will ideally be based in the Chicago area for a light hybrid onsite/remote work model, but we are open to remote locations across the U.S. and Canada. Itching to extend and build upon your passion for digital craft? You found the right place.

Requirements

3 or more years of experience, ideally in an agency or consulting environment
Advanced practitioner of HTML, CSS, and JavaScript using current best practices
Strong proficiency with TypeScript. Comfortable in a codebase and able to model complex data well
Significant production experience with React and Next.js
Bespoke CSS/SCSS fluency. Comfortable architecting styles from scratch without leaning on Tailwind or other utility frameworks. We value craft over shortcuts here
Experience designing, building, and consuming component libraries and design systems
Deep proficiency with Figma and the broader Figma product suite (Figma Design, Dev Mode, FigJam, variables, libraries). You can navigate complex files, spot opportunities and conflicts early, and partner fluently with designers
Ability to build resilient, responsive sites that deliver consistent experiences across screen sizes, devices, and browsers
Demonstrated ability to meet WCAG 2.2 accessibility standards
Solid grasp of SEO fundamentals, especially semantic markup and Core Web Vitals
Hands-on experience with headless CMSs (Contentful, Sanity, Contentstack, or similar), including content modeling collaboration in addition to integration
Comfortable integrating third-party libraries and SDKs to meet project requirements
Confident with Git workflows, branching strategies, and code review
Experience with JavaScript animation libraries (GSAP, Framer Motion, Three.js, etc.)
Hands-on experience with AI-assisted development tools (Copilot, Cursor, Claude Code, etc.) and a clear point of view on where they help and where they hurt. It's equally important that you can do excellent work without them. AI accelerates good engineers, and the fundamentals still matter. We're looking for people who reach for AI as one tool among many.

Responsibilities

Collaborate with multi-disciplinary teammates to deliver strategic solutions to our clients' challenges
Act as the technical lead on front-end projects, providing thoughtful guidance, code review, and mentorship
Contribute to and help evolve our internal standards, component patterns, and engineering practices
