Sr Software Engineer, Web

Position Title: Senior Software Engineer, Web

Location: Remote from the U.S. 

About the role

Join the LTK Family! We are searching for a senior software engineer to join the Creator organization. This team is responsible for the user experiences and systems used to onboard creators and drive their growth across LTK, one of the largest creator-guided shopping and brand marketing platforms in the industry.

The ideal Senior Software Engineer for this space will be organized, productive, and comfortable working across the full stack. You will have strong experience in building scalable, production-quality web applications that anticipate significant growth across multiple dimensions. You’ll be inventive and have a pragmatic and iterative approach to delivering high quality software. You’ll ruthlessly prioritize accomplishing the highest impact deliverables first, and provide valuable guidance to the engineering manager on the direction of the team’s web architecture and systems. You will proactively establish lines of communication across the teams and business units, and draw on them to make the team successful.

This is a web-application focused role: you will spend most of your time designing, building, and evolving front-end experiences. We prefer candidates who are comfortable working across the full stack and can lean into backend work when needed.

How you will make an impact

• Coming up with feasible and practical solutions to tough problems.
• Design, build, and maintain high-quality web experiences using modern frameworks such as React.js and Vue.js.
• Take end-to-end ownership of web features: from early technical design and prototyping through implementation, testing, rollout, and ongoing iteration.
• Collaborate with product, design, and other engineers to deliver intuitive, performant, and accessible web experiences that delight creators and brands.
• Optimize web applications for performance, scalability, and reliability, including bundle size, loading performance, and runtime responsiveness.
• Champion web best practices in accessibility, usability, security, and cross-browser compatibility.
• Use AI tools to expedite daily workflows (e.g., code generation, refactoring, test creation, documentation) and to improve both speed and quality of web development.
• Leverage AI-assisted development practices to prototype, iterate on, and maintain web features efficiently, while holding a high bar for safety and code quality.
• Write very high-quality, well-tested code that is robust and easy to maintain.
• Take ownership of projects and drive them to completion.
• Work and succeed in a fast-paced and agile development environment.
• Identify and drive improvements to our web architecture, tooling, and development processes.
• Conduct constructive peer design/code reviews and provide clear, actionable feedback.
• Work with distributed teams across different time zones.
• Serve as a technical subject matter expert for web development who mentors fellow engineers, demonstrates technical experience, and leads teams in solving challenging problems.

What you will bring to LTK

• Deep experience with modern web development
• Demonstrated proficiency in React.js (or another comparable framework), including building complex, component-based single-page applications
• Strong understanding of front-end architecture and patterns (component design, state management, routing, modularization).
• Experience with modern web tooling and ecosystems (e.g., Webpack/Vite, npm/yarn, linting, formatting, testing frameworks such as Jest, React Testing Library, Cypress, or similar).
• History of designing and building highly scalable, resilient web experiences that serve a growing user base.
• Experience integrating with backend services and APIs (REST/JSON, HTTP; GraphQL) and working closely with backend teams to define interfaces and contracts.
• Strong focus on performance, accessibility, security, and usability in web applications.
• Demonstrated experience using AI tools as part of the software development lifecycle (coding, debugging, testing, documentation) with concrete examples of improved productivity or quality.
• Ability to critically evaluate AI-generated code, refine it, and integrate it safely and effectively into production systems while maintaining team standards and best practices.
• Comfortable shipping code multiple times per day.
• Strong technical leadership and mentoring skills.
• Ability to model and conceptualize integrations across complex systems and how web surfaces interact with underlying services.
• Excellent verbal and written communication skills to both technical and non-technical audiences.

Preferred (Fullstack)
