Job description

At BairesDev®, we've been leading the way in technology projects for over 15 years. We deliver cutting-edge solutions to giants like Google and the most innovative startups in Silicon Valley.

Our diverse 4,000+ team, composed of the world's Top 1% of tech talent, works remotely on roles that drive significant impact worldwide.

When you apply for this position, you're taking the first step in a process that goes beyond the ordinary. We aim to align your passions and skills with our vacancies, setting you on a path to exceptional career development and success.

Senior Frontend Engineer – React/Next.js + AI at BairesDev

In this role, you'll own frontend experiences on a streaming chat product that's expanding into analytics views where accuracy directly shapes customer conversations. You'll build within an established design system, crafting reusable components and validating AI-driven experiences with real rigor rather than by inspection. This is your opportunity to bring both frontend craft and AI fluency to a product where precision genuinely matters, extending backend services when the frontend needs them and raising experience issues before anyone has to ask.

What You'll Do

• Build and own frontend experiences for a streaming chat application expanding into analytics views.
• Develop reusable components and hooks within an established design system.
• Validate AI-driven experiences against evaluation sets rather than manual inspection.
• Extend Python services where frontend functionality requires backend support.
• Proactively surface experience issues rather than waiting for feedback.

What We Are Looking For

• 5+ years of experience with React and Next.js using TypeScript.
• 2+ years of experience with AI/ML-driven applications, including LLM integrations.
• Experience with LLM evaluation, including LangSmith, LLM-as-judge, offline evals, or golden datasets.
• 2+ years of experience with Python.
• Experience with AWS.
• High attention to detail in UI, including pixel accuracy, proactive polish, and design spec fidelity.
• Advanced proficiency in English.

Nice To Have

• Experience with analytics and charting UI, including funnels, bar and time series charts, using D3, Recharts, or Visx.
• Familiarity with generative UI and AI-generated experiences, including model-driven components.
• Experience working inside an established design system such as Odyssey, Material, or Carbon.
• Strong accessibility (a11y) and responsive web app practices.
• Experience with streaming chat interfaces, including LangGraph API, WebSockets, and token streaming.

How we do make your work (and your life) easier:

• 100% remote work (from anywhere).
• Excellent compensation in USD or your local currency if preferred.
• Hardware and software setup for you to work from home.
• Flexible hours: create your own schedule.
• Paid parental leaves, vacations, and national holidays.
• Innovative and multicultural work environment: collaborate and learn from the global Top 1% of talent.
• Supportive environment with mentorship, promotions, skill development, and diverse growth opportunities.

Join a global team where your unique talents can truly thrive and make a significant impact!
