Senior Developer - Javascript/TypeScript

We are looking for a Lead Frontend Developer who is hands-on and can also lead our teams and put in place best practices for software engineering for Web UI development.

We are looking for a hardcore technologist, not a project manager. If you enjoy solving hard problems and raising the bar for frontend quality, this role is for you.

Responsibilities

• Own the technical strategy and frontend architecture of web projects
• Set the technical direction and enforce best practices to design and build high-performance, secure, maintainable UI code
• High-level & low-level software design, hands-on development & deployment of applications
• Work with backend, QA, and product to meet performance, security, and reliability goals
• Mentor engineers by example, not by assigning tickets
• Put in place good practices for robust, pixel-perfect UI development across multiple projects

Required Skills and Experience

• 7+ years building complex web applications
• Deep hands-on experience with React, Angular, Vue, or similar frameworks
• Strong HTML5, CSS3 (including preprocessors or CSS-in-JS)
• Strong TypeScript / JavaScript skills
• Proven track record of improving performance, security, or maintainability in production
• Experience writing unit, integration, and end-to-end tests
• Demonstrated technical leadership — setting standards, driving architectural change, mentoring peers
• Comfortable discussing trade-offs and making decisions without a manager’s sign-off
• Experience with CI/CD pipelines and automated testing frameworks
• Understanding of OWASP security basics for frontend applications
• Ability to profile and optimize bundle size, render time, and memory usage

Nice-to-have Skills

• Experience with server-side rendering or static site generation
• Knowledge of GraphQL, WebSockets, or other real-time APIs
• Contributions to open-source projects or public tech talks

Our Expectations

• You produce clean, readable code that others can follow
• You own the outcome of the frontend stack, not just the task list
• You optimize performance and put in place security measures for projects
• You question shortcuts that compromise quality
• You share knowledge through code reviews, brown-bag sessions, or pair programming

We are looking for a highly motivated individual that can help us solve interesting and complex problems for our clients. You will be working closely with product and engineering teams based out of the USA, Europe, and India to build proof-of-concepts, validate strategic architecture decisions, and develop modern and scalable solutions. We firmly believe that your success is our success, and we are willing to take a stake in that.
