The Role
We are looking for someone with solid foundational skills who is eager to grow, learn, and collaborate with a team to help build efficient, elegant, and intuitive user interfaces for enterprise solutions in the financial industry.
As a Frontend Engineer, you’ll work directly with product managers, designers, and backend engineers to turn business requirements into clean, tested, maintainable code. You’ll get detailed code review from senior engineers, and you’ll be expected to ask questions, challenge requirements, and bring your own opinions to the table. We hire engineers who want to understand why they are building something, not just what to build.
Our Engineering Team
The CMG engineering team is made up of domain experts who collaborate across disciplines and share knowledge openly. We value engineers who are passionate about modern technologies and best practices who can raise the bar for React, TypeScript, UI architecture, testing, accessibility, and developer experience. Our engineers are encouraged to challenge the status quo and are constantly seeking improvement and efficiency in our codebase and platform. CMG engineers are empowered to explore solutions and bring recommendations to the table. We are in a period of making impactful engineering decisions, and this role will help guide frontend technical direction through research, prototyping, code review, and production-quality implementation.
Responsibilities
Contribute ideas to product discussions and help solve real user problems.
Work in an AI-first development flow. Use tools like Claude, Codex and GitHub Copilot not just to go faster, but to do more: explore multiple approaches, validate ideas quickly, and build things that previously wouldn't have been worth the effort.
Uphold a high-quality bar. Engineers write their own tests at the unit, integration, and end-to-end levels, and every line of code, human-written or AI-assisted, is reviewed by a human before it ships.
Collaborate with product teams to translate UI/UX wireframes and mockups into functional, high-quality code.
Collaborate with senior engineers and engineering managers to ensure that the overall product meets all requirements and specifications.
Write clean, maintainable code and unit tests while actively learning from senior engineers during code reviews.
Stay current with emerging front-end technologies and trends, continuously improving development practices and tooling.
Participate in the team's on-call rotation to help diagnose and minimize production incidents. Use DataDog, OpenTelemetry, and Microsoft Azure to quickly diagnose incidents, minimize impact, and harden the system against recurrence.
