Senior Frontend Engineer
Hybrid, Bucharest, Romania
JOB OVERVIEW
Legion is a high-performance, data-driven enterprise platform that supports complex forecasting, scheduling, and optimization capabilities. It also provides the services required by our web and mobile frontend applications.
RESPONSIBILITIES AND DUTIES
As a Senior Frontend Software Engineer, you will be a member of the team responsible for the implementation and evolution of these applications.
You will need to be able to write secure, efficient, enterprise-quality code and have a deep understanding of the techniques and technologies necessary for scalability and performance.
Plan and conduct architecture sessions, design and build enhancements and extensions, and create plans for integration and unit testing.
Collaborate independently across frontend, backend, product, design, and quality engineering teams to resolve dependencies and make well-informed technical decisions.
Design and maintain highly available, reliable, and performant frontend applications that meet defined service-level agreements (SLAs) and service-level objectives (SLOs).
Manage difficult situations in a calm, structured, and timely manner.
Remain adaptable and prepared to respond effectively as priorities and requirements change.
Participate in Agile and Scrum ceremonies and contribute to planning, estimation, delivery, and continuous improvement.
Apply AI-assisted software development lifecycle (AI SDLC) practices across requirements, design, coding, testing, documentation, and automation to improve delivery velocity and quality.
Please note that this role involves active participation in an on-call rotation for critical support activities.
REQUIRED SKILLS AND QUALIFICATIONS
5–7 years of experience working with React and related frontend technologies.
Experience with React is essential. Experience with AngularJS and migrating AngularJS applications to React is preferred.
Strong experience with HTML5, CSS, JavaScript, TypeScript, and responsive, cross-browser frontend development. Familiarity with Bootstrap and jQuery is helpful when working with legacy applications.
Experience integrating frontend applications with REST APIs using modern state-management, data-fetching, caching, and error-handling patterns (e.g., Redux, Zustand, or TanStack), and writing automated frontend and end-to-end tests with Playwright.
Experience building software products and managing the complexities of multiple configurations in a cloud-based product, rather than consulting or webpage/portal development.
Bachelor’s or master’s degree in computer science, engineering, mathematics, or a similar field.
PREFERRED QUALIFICATIONS AND ATTRIBUTES
Experience with mobile application development, including native iOS or Android applications; familiarity with React Native is a plus.
Our application runs on AWS, so experience with containerization and cloud deployments is preferred.
Familiarity with Java-based backend development and working with backend services and APIs is desirable.

BACKGROUND AND OPPORTUNITY
There are almost 75 million hourly workers in the United States, representing more than half of the entire workforce. Historically, managing hourly employees has been difficult due to high attrition (average of 60%) and high replacement costs (average of $3,200 per employee in retail). The ongoing labor shortage and competition from the gig economy, make it more difficult to attract and retain hourly employees. The top reasons hourly employees leave their jobs are a lack of schedule empowerment, poor communication with employers, and an inability to get paid early. Gen Z and the millennial workforce demand gig-like flexibility, modern technology, and compelling work options. Legion’s mission is to turn hourly jobs into good jobs, serving the hourly workers who make up the majority of the US workforce. We believe in empowering employees and helping employers be efficient and innovative by enabling intelligent automation powered by Legion’s Workforce Management platform to optimize labor efficiency and enhance the employee experience simultaneously.
Legion WFM was built for the cloud with AI at the core and is designed to handle the complexity of modern businesses and meet the needs of today’s hourly employees. Our team is composed of dedicated individuals from all backgrounds and experiences, globally distributed across all time zones.
