Job DescriptionFront-end React Engineer (Payroll Or Freelance)
We are looking for a Frontend React Engineer to take ownership of the supplier-facing portal experience. You will design and implement secure login, onboarding and escalation flows, build audit-trail user activity tracking, and later extend the platform with dashboards, reporting views, and “where-used” exploration for compliance data.
This position is ideal for a frontend engineer who enjoys working with React in enterprise environments and who wants to make a visible impact on a global compliance platform.
Key Responsibilities
Phase 1 (Months 1–3):
What probably makes us unique as an IT services company is the human touch. First among our values, we believe in real human contact as a basis for positive outcomes. We meet everyone eye-to-eye, with the intention of building strong, mutually supporting partnerships. With our customers, but also among our teams and employees. As a company, we are committed to being inclusive and diverse; we treat people as we expect them to treat us.
