• Lead and execute end‑to‑end AI/ML research initiatives with significant business impact.
• Identify high‑value opportunities, build prototypes, design experiments, validate hypotheses, and bring successful approaches into production.
• Serve as a technical mentor—elevating teammates through code reviews, architectural guidance, technical strategy, and hands‑on coaching.
• Collaborate closely with cross‑functional leaders to drive product discovery and define what will deliver real value to our clients.
• Navigate ambiguous, complex problems with creativity and a first‑principles mindset.

• You have strong data intuition, especially in environments where off‑the‑shelf approaches fail and novel solutions are required.
• You have a product‑oriented mindset, capable of pitching ideas and influencing stakeholders across all levels.
• You work with confidence but without ego, balancing strong opinions with openness to being challenged.
• You seek out and foster diversity of thought, and you excel at building from common ground.
• You’re a creative problem‑solver who thrives when inventing what doesn’t exist yet.

• Experience collaborating within an agile, distributed, multi‑timezone research team.
• Exceptional communication skills across technical and non‑technical audiences.
