Job Description

ML/AI Engineer

Ubiminds

• Lead all ML/AI engineering efforts as the first dedicated member of this domain. • Design, build, and ship ML/AI-powered features across multiple products. • Partner closely with Product, Engineering, and Operations to identify high-value opportunities and convert them into production systems. • Own the full lifecycle of ML solutions: problem framing, prototyping, modeling, deployment, monitoring, and continuous improvement. • Establish best practices, tooling, and standards for ML/AI development, experimentation, and observability. • Build and improve data pipelines and feature stores to support robust ML workloads. • Collaborate in architecture reviews, roadmapping, and cross-team planning. • Mentor other engineers on ML/AI concepts and help grow the ML/AI team as the practice scales. • Contribute to a high-quality codebase using TDD, code review, and well-structured engineering practices.

Job Requirements

  • Strong track record of building and launching ML/AI systems in production environments (not only prototypes or research).
  • Experience across the entire ML lifecycle: data preparation, modeling, evaluation, deployment, and monitoring.
  • Hands-on experience with modern AI approaches such as LLMs, retrieval-augmented generation, and/or traditional ML algorithms.
  • 8–10+ years of software or ML engineering experience.
  • Proficiency in at least one major ML/AI development language (Python preferred).
  • Comfortable collaborating in a polyglot engineering environment (team heavily uses Ruby).
  • Experience building from 0→1 in ambiguous environments with high autonomy.
  • Strong communication skills and enthusiasm for transparent, positive collaboration.

Benefits

  • Are placed in a product-based company, treated like a full-time team member.
  • Count on our full back-office support: career guidance, HR, and concierge services.
  • Enjoy our remote-first policy.
  • Get your own MacBook (no BYOD here!).
  • Access tech talks, chapter meetings, and a strong community of top engineers.
  • Improve your English through free lessons with a native English speaker.
  • Earn a referral bonus when recommending new Ubiminders.
  • Want office vibes sometimes? Our Florianópolis HQ is open — snacks, massages, drinks, and games included.
