Senior Frontend Engineer

Senior Frontend Engineer Location: Belgrade / Novi Sad About Daon Daon is a global leader in the defence against digital identity fraud and AI-generated synthetic identities. For over a quarter of a century, we have partnered with governments and leading enterprises to deliver secure, seamless identity experiences across financial services, telecommunications, healthcare, travel, and critical infrastructure. Our TrustX platform enables organisations to orchestrate secure, scalable, cross-channel identity workflows, supporting identity verification, biometric authentication, and lifecycle management across complex environments. More than two billion identities worldwide have been safeguarded by Daon technology. Recognised as a leading provider by multiple analyst firms including Gartner®, Kuppinger Cole, and Frost & Sullivan®, Daon is at the forefront of shaping the future of identity security. Role Overview As a Senior FrontEnd Engineer on our TrustX SaaS platform, you will design and develop user‑facing interfaces that power both customer‑facing experiences and internal back‑office tools. You will work closely with UX designers, architects, backend engineers, DevOps, mobile teams, and service delivery managers to build scalable, modular, and reliable front‑end applications. We’re looking for strong engineers with broad systems understanding, not just pixel‑perfect implementers. You should know how front‑end components fit into a cloud‑native SaaS architecture, how to integrate with distributed backend services, and how to design UI modules that are flexible, maintainable, and easy to evolve. A major part of this role is helping shape and advance a pluggable, micro‑frontend architecture, enabling teams to ship UI functionality independently and reuse common components across multiple products. You will also be expected to adopt AI‑assisted development (GitHub Copilot, AI-driven UI scaffolding, test generation, etc.) to improve speed and quality. What you will do : Frontend Development and Collaboration Build modern, responsive, and accessible UI applications using frameworks such as React, Angular, or Vue. Implement complex workflows, dashboards, forms, and interactive features for both end‑user and back‑office user experiences. Integrate UI components with backend services through REST APIs, authentication flows, and event-driven patterns. Develop reusable UI components, shared libraries, and design‑system compliant elements. Design and implement modular, decoupled front‑end components that can be embedded, swapped, or extended without impacting other services. Help define standards for micro‑frontend boundaries, routing strategies, shared assets, and inter-module communication. Work with architects and backend teams to ensure seamless integration across distributed services and environments. Use GitHub Copilot to accelerate coding, test generation, documentation, and boilerplate creation. Participate in the adoption and refinement of AI‑driven workflows for front-end development. Help the team continually improve how AI is used for productivity, quality, and maintainability. Optimize UI performance (rendering, load time, caching, virtualization, batching). Ensure accessibility compliance (WCAG standards). Work closely with QA leads to ensure reliable, production‑ready features. Partner with designers to translate UX wireframes into high-quality, maintainable implementations. Collaborate with backend and API teams to shape contracts, define data flows, and identify integration risks early. Support service delivery managers to ensure smooth releases, environment readiness, and predictable front‑end deployments. Participate in code reviews and mentor junior engineers. Support occasional troubleshooting efforts for complex defects or production issues. What you have: 5+ years building production front‑end applications for enterprise or SaaS environments.
