Engineering Director, AI Developer Experience (AIDE)

About The Role

Nubank is one of the few companies with the scale (3,500+ engineers), AI ambition, and executive air cover to build a genuinely AI-native developer experience: not a bolt-on pilot. This role is responsible for defining and leading the AI Developer Experience pillar within Engineering Enablement, transforming how Nubank's engineers write, review, deploy, and operate software.

The Director inherits a mandate, a growing team, and a seat at the table with the CTO. The pillar already has real momentum: an early production win in the Vector agentic coding platform, an urgent context-infrastructure buildout, and direct executive sponsorship.

Core Workstreams

• NuContext: the knowledge and context-extraction layer (docs, Confluence, Jira, code) that everything else depends on; currently the single highest-priority area for Nubank's long-term AI strategy.
• Vector (agentic coding & hosted environment): sandboxing, harness, memory/retrieval, and system-prompt optimization for AI-assisted coding.
• Agentic Code Review: AI-assisted PR review to cut defect rates and cycle time, a direct lever on the org's top-line change failure rate (CFR) goal.
• AISRE: moving from vendor evaluation to AI-native incident detection, diagnosis, and remediation at scale.
• Prompt Classification & Model Routing and 3rd-party AI tooling vendor management: scope and placement still being finalized; the Director will help shape this boundary.

Qualifications

• Proven leadership of AI-native developer tooling or platform teams, ideally at a company operating at meaningful engineering scale.
• Track record building full-time, dedicated engineering teams out of fragmented, part-time, or borrowed resourcing: including experience in allocating teams, stellar in people leadership to do it without burning teams out.
• Real experience structuring and running third-party vendor partnerships (evaluation, integration, managing lock-in risk) alongside first-party build.
• Hands-on technical credibility in agentic coding systems, context/retrieval infrastructure, or developer-facing AI tooling: able to go deep with ICs, not just manage from a distance.
• Comfort operating in a high-velocity, ambiguous, and high-executive-visibility organization; ability to align and mobilize teams to take on new challenges and scale impact.
• High accountability and ownership mindset, coupled with the ability to move fast under pressure.
• Comfort with an honest, unsolved problem space: even leading peer companies are far from 100% AI-authored code; this role is about the challenge and the resourcing to attack it, not a pre-solved problem.
• A builder's instinct for evaluation rigor: experience designing evals/benchmarks that replace subjective quality judgments with objective, repeatable measurement.
• Experience with sandboxed agentic execution environments, retrieval-augmented systems, or LLM-based code review tooling (nice-to-have).
• Familiarity with token-cost management as AI spend scales (nice-to-have).
• Prior exposure to fintech, regulated environments, or large legacy codebases where AI adoption is harder to get right (nice-to-have).

Core Leadership Skills

• BUSINESS ACUMEN: Drives strategic business alignment at Nubank by analyzing market dynamics, identifying opportunities, and ensuring informed decision-making to influence organizational direction.
• COMMUNICATION: Masters complex communication, mentoring others, fostering open dialogue, and adapting strategies to enhance organizational effectiveness.
• AGILE ADAPTABILITY: Leads with agility, pioneering solutions, fostering a culture of learning, collaboration, and continuous value delivery.
