Freelance Next Js Developer Jobs in Washington (NOW HIRING)

We are looking for a Senior Software Engineer to join our frontend team and play a critical role in building the platform that will define CaseGuard's next chapter.

You will design and build a highly performant, sophisticated frontend capable of handling complex media redaction directly in the browser. This role involves more than just building forms; you will be responsible for the architecture that supports real-time collaboration, complex document rendering, and high-stakes video manipulation.

This role is expected to operate with a high degree of ownership. You will take responsibility for major frontend features and drive them end-to-end from design through production with minimal oversight. Beyond writing excellent code, you will contribute to engineering standards, influence frontend architecture, and help scale both the system and the team.

• Build scalable, maintainable frontend applications using Next.js, React, and TypeScript.
• Implement advanced rendering and manipulation logic for PDF documents and video within the browser.
• Utilize WebGL and Canvas to ensure smooth, performant interactions for redaction tools.
• Build and maintain real-time features using WebSockets and SignalR to support concurrent multi-user workflows.
• Work closely with backend engineers to consume REST APIs, defining contracts that ensure efficient data flow and optimal UX.
• Manage frontend deployments on AWS and maintain robust CI/CD pipelines to ensure rapid, reliable delivery.
• Identify and resolve frontend bottlenecks (rendering lag, memory leaks, bundle size) to ensure a seamless user experience under heavy load.

• Turn ambiguous product requirements into well-defined technical tasks and execution plans.
• Take full ownership of major frontend domains, driving them from initial design through to production deployment.
• Make independent technical decisions regarding frontend state management, component architecture, and styling patterns.
• Drive frontend decisions in cross-functional work, ensuring the system design is robust and provides the best possible user experience.
• Be accountable for the reliability, performance, and accessibility of the features you ship.

• Conduct thorough code reviews and uphold high engineering standards for the frontend guild.
• Participate in architectural discussions and contribute to long-term frontend roadmap decisions.
• Mentor junior and mid-level engineers to support their technical growth.
• Contribute to hiring by reviewing technical assessments and interviewing prospective candidates.

• 6+ years of experience owning and delivering complex frontend applications or major features end-to-end.
• Strong proficiency in React, Next.js, and TypeScript.
• Deep understanding of modern frontend architecture, state management, and hooks.
• Solid experience working with REST APIs and real-time communication via WebSockets or SignalR.
• Practical experience working with WebGL, HTML5 Canvas, or complex browser-based document/video manipulation.
• Professional experience with Git, CI/CD pipelines, and AWS deployment strategies.
• Strong communication skills and the ability to collaborate effectively across a hybrid team.

• Experience building heavy, data-intensive web applications (e.g., editors, design tools, or analytical Dashboards).
• Knowledge of frontend security best practices (CSPRNG, XSS prevention, secure storage).
• Experience with AWS services relevant to frontend/custom Next.js hosting (CloudFront, S3, ECS).
• Familiarity with Tailwind CSS or advanced CSS-in-JS libraries.

• Meaningful equity - we believe in sharing ownership with the people who build the company
• Competitive base salary alongside an equity-heavy compensation package
• Hybrid working - flexibility to work remotely with regular in-person collaboration
• Direct influence over architecture, engineering culture, and the technical roadmap
• Opportunity to take ownership of critical backend domains in a growing cloud platform
• A small, high-trust team that moves fast, values craftsmanship, and ships quality software
• Medical, Dental, and Vision Insurance
• 401K
• Paid Vacation
• Ten paid holidays per year
• Friendly and Learning environment

Salary+ Equity Range: $120,000 to $200,000
