Senior Front-End Engineer (Ember.js)

At Codelitt, we are more than just a product-development company - we are creators, innovators, and problem solvers. Our mission is to help companies unlock their potential by building exceptional digital experiences. We partner with businesses to bring their most ambitious ideas to life, from concept to launch and beyond. Our team thrives on challenges, pushing the boundaries of technology to craft solutions that make a real impact. If you're passionate about innovation and love tackling meaningful problems, you’ll find your home at Codelitt.

About the Role We’re teaming up with a global fintech leader to build a guided, data-seeded demo experience that lets prospective clients explore the core platform before they buy. You’ll be the senior front-end engineer on a small, cross-functional squad charged with shipping the MVP. The codebase is a modern Ember.js app connected to a large Java REST back end. You’ll own rich UI flows, inject realistic demo data, and ensure the experience mirrors production quality.

Who You Are

Ember-fluent. You have deep experience with Ember.js (or can ramp up fast) and know its conventions inside out. No back-end development required—your focus is 100% front end.

Design-system champion. You’re comfortable building and extending component libraries, token-based theming, and responsive layouts.

UX-centric. You think in flows and micro-interactions—accessibility and performance are always top of mind.

Ownership-oriented. You unblock yourself, keep scope laser-focused, and communicate progress proactively across time zones (US & LATAM).

Collaborative communicator. You enjoy partnering with designers and PMs, giving / receiving feedback, and demoing work early and often.

Revamp & Refactor

Audit the existing Ember codebase, identify modernization opportunities, and break work into incremental PRs.

Seed the environment with internally consistent fake data for realistic demos.

Implement the Design System

Build reusable, documented components (with Storybook or similar) that adhere to brand guidelines and WCAG accessibility standards.

Collaborate with designers to evolve tokens, variants, and interaction patterns as real-world needs emerge.

Ensure Quality & Maintainability

Write robust unit, integration, and visual regression tests.

Champion best practices in code reviews, linting, performance profiling, and CI / CD.

Collaborate & Deliver

Pair with client engineers, designers, and PMs to refine scope.

Demo progress weekly, iterate on feedback, and hit the January launch window.

Preferred Qualifications

5+ years professional front-end experience with SPAs; 2+ years working extensively in Ember.js (or demonstrably fast ramp-up).

Hands-on experience rolling out or evolving a design system (tokens, theming, documentation).

Strong grasp of state management, component architecture, and automated testing.

Familiarity with accessibility standards (WCAG 2.1+), performance budgeting, and CI / CD pipelines.

Bonus : experience migrating legacy Ember apps to Octane / Glimmer components or TypeScript.

Soft Skills

Excellent problem-solving skills and attention to detail

Strong communication skills and a collaborative mindset

Ability to work effectively in a remote, cross-functional team

Proactive and adaptable to a fast-paced development environment - especially vital on a six-month runway
