Can you imagine building AI Agents that transform the way digital products are designed?
Join our expert team to work on an innovative Design initiative, contributing to the development of AI-powered assistants that improve accessibility and productivity across digital product design. You will apply your knowledge of Generative AI, Python, and LLMs to build intelligent workflows that support designers from the earliest stages of product development.
At ERNI, you are never just a number. Even if you work on an external project, you will feel part of the team and always supported.
How do we make this happen?
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
- Hands-on experience building AI Agents and LLM-based applications using Python.
- Strong knowledge of LangGraph, LangChain, CrewAI or similar AI frameworks.
- Experience working with Claude or other modern Large Language Models and Prompt Engineering techniques.
- Ability to collaborate closely with UX Designers and non-technical stakeholders to translate business needs into AI solutions.
- Advanced English. Experience working with Design, UX, Accessibility or Figma environments is considered a strong advantage.
You will be responsible for designing and developing AI Agents and intelligent workflows while collaborating closely with UX Designers and Accessibility Specialists. You will prototype AI solutions using LLMs, evaluate the most suitable technical approach, integrate AI capabilities with design tools where applicable.
What if the project ends?
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.
