Can you imagine building the user experience behind a platform that supports pharmaceutical innovation? πŸ’ŠπŸš€

At ERNI, we're looking for a Senior Frontend Product Engineer to join an international project within the pharmaceutical industry. You'll play a key role in the evolution of a product that helps manage and visualize data from different manufacturing and laboratory sources, enabling more efficient and data-driven processes.

This is a frontend-focused position where you'll develop modern React applications while ensuring an excellent user experience. Beyond coding, you'll collaborate closely with the product team to translate user needs into intuitive interfaces, maintain the design system, and contribute to the product's future evolution.

How do we make this happen? πŸ€”

With people. Besides your team and manager, you will have several support figures like a godparent, who will help you with the practical and administrative aspects of daily life during your first 6 months.

And the second most important person after you, your mentor, who will guide you through your entire onboarding and career at ERNI. You will have regular 1:1 meetings with them, and recurrently, you will work on your development plan to define your short-, medium-, and long-term goals.

At ERNI, we highly value experience and technical knowledge. As a senior profile, you will have the space to continue growing, whether by deepening your technical skills or having greater influence on project decisions, with autonomy and the opportunity to share knowledge with other experts.

And if you are interested in mentoring, there is also space for that: supporting other ERNIans while still focusing on the technical excellence that sets us apart.

What You Will Bring 🀝

  • Strong experience developing applications with React.
  • Deep knowledge of building reusable and modular React components.
  • Experience working with design systems and scalable frontend architectures.
  • Strong understanding of UX/UI principles and user-centered design.
  • Experience collaborating within Agile teams.
  • Ability to transform business requirements into intuitive user experiences.
  • Professional English (minimum B2/C1).
  • Strong communication skills and product mindset.

You will be responsible of developing and evolving a React application focused on delivering a simple, responsive and intuitive user experience.

You'll build reusable components, ensure consistency across the design system, collaborate with Product and UX stakeholders, and contribute to the evolution of the product roadmap as new capabilities are introduced.

What if the project ends?πŸ˜…

We work on a wide variety of projects, technologies, and sectors, allowing you to keep growing in different environments. If a project ends or you feel ready for a new challenge, we will find another one that aligns with your professional development.

Our working model πŸ‘©β€πŸ”¬

We ask you to be available for key meetings. Need to leave for a doctor’s appointment or to pick up your child from school? No problem. We trust you to deliver quality work within your 40-hour workweek.

Our model is hybrid: we usually go to the office 2 days a week, though this depends on the project and team, but we love seeing each other’s faces; the best stories always happen in the office!
