Overview

Head of Research (AI) at Avra. Avra is a deep tech platform powered by foundational AI that translates the complexity of SMBs into strategic decisions for large enterprises. We develop our own Graph Foundation Models from the ground up to deliver insights that empower enterprises across Latin America.

We were founded in 2024 and are backed by industry partners.

The role This is a leadership role for a hands-on "player-coach" who will own and elevate our research function. Your mission is to scale the scientific vision for our Graph Foundation Models, raise the technical bar for the team, and bridge the gap between cutting-edge research and production-grade capabilities that move our clients\' most important metrics. You will partner with Data Platform (graph & data pipelines) and Product Engineering (serving & MLOps) to transform ambitious ideas into the core of Avra\'s platform.

What You\'ll Do
  • Leadership & Scientific Strategy

    • Lead, mentor, and grow a world-class team of research scientists and engineers.
    • Establish and champion a rigorous research cadence: from hypothesis definition and RFCs to disciplined experimentation and data-driven decision-making.
  • Hands-On Research & Engineering
    • Design and implement state-of-the-art GNNs for our large-scale graph. Solve problems in node, edge, and graph-level tasks, multi-scale embeddings, and temporal/inductive generalization.
    • Build reliable, reproducible training and evaluation pipelines using PyTorch, PyG, and distributed training frameworks.
    • Define and maintain gold-standard benchmarks, ensuring statistically sound model comparisons.
  • Production & Delivery
    • Collaborate with Product Engineering to productionize models for batch and online inference for customers.
    • Partner with GTM teams to define success criteria for enterprise client bake-offs and communicate impact to technical and executive stakeholders.
    • Ensure research accounts for real-world challenges, including concept drift, and improve deployment strategy in regulated contexts.
You Should Have
  • 7+ years of experience in AI/ML (or a PhD + 4 years) with significant contributions in the field.
  • Demonstrated ability to ship research into production: ideas from papers or prototypes to scalable, reliable code that delivered measurable business impact.
  • Hands-on excellence in Python and PyTorch, with deep proficiency in graph learning libraries like PyTorch Geometric or DGL.
  • Solid software engineering fundamentals, including testing, profiling, and building maintainable systems.
  • Proven experience mentoring and leading technical projects or managing a small team (2-6) of scientists/engineers.
  • Professional proficiency in both Portuguese and English.
Preferred Qualifications
  • Experience with distributed training and inference.
  • Experience working with graph-based models.
