ABOUT THE ROLE 

We’re looking for a Staff Technical Product Manager who is passionate about Security, Identity, and building foundational products that will shape how millions of users, merchants, services, and AI agents securely interact with the VTEX platform.

As a PM in Identity & Shield, you will own the vision and execution of mission-critical initiatives that ensure trust, compliance, and secure autonomy across our ecosystem. You will help reinvent how access, authorization, and protection work in a world where AI agents increasingly act on behalf of humans and businesses.

This is one of the most strategic roles in the company: you will drive core platform capabilities used by every product area, while also evolving Shield — one of VTEX’s top-selling add-ons — to meet the needs of global enterprises and highly regulated industries.

WHAT YOU WILL DO 

• Define the long-term strategy for Identity at VTEX, aligned with the Re-Invent Security mission to make VTEX the most secure AI-Native commerce platform.
• Lead the redesign of VTEX’s Access Management Module, delivering an agentic, automated, low-friction experience that reduces operational burden and mitigates credential misuse risks.
• Partner deeply with engineering leads to design guardrails, policies, and control layers that ensure AI agents operate only within safe, compliant, and auditable boundaries.
• Own the roadmap and evolution of VTEX Shield, expanding its value proposition for enterprise customers and regulated industries.
• Translate complex customer security needs (CISO-level requirements, compliance frameworks, SOC controls, auditability, etc.) into actionable product requirements.
• Partner with Sales, Customer Success, and Professional Services to ensure Shield continues to grow ACV, adoption, and customer satisfaction.
• Benchmark leading enterprise security solutions to drive Shield toward a global, competitive positioning.
• Build platform-wide primitives that allow product teams to easily integrate identity, permissions, and agent governance patterns into their workflows.

WHO YOU ARE

• You have a strong background as a Product Manager working with complex products.
• You can quickly ramp up on technical domains — you don't need to be an expert on day one, but you're comfortable going deep with engineering teams and picking up new concepts fast.
• You have experience working with demanding customers — enterprise, global brands, or heavily regulated industries.
• You can connect deeply technical concepts to clear business outcomes, and communicate strategy and trade-offs to engineers, leadership, and customers alike.
• You thrive in complex environments where multiple teams depend on your product to build and scale safely.
• You're comfortable with data: logs, monitoring, dashboards, and product metrics that inform risk and prioritization decisions.
• You're curious and critical about the role of AI and LLMs in the future of commerce and security. 
• Fluent in English.

• Partner with risk leaders (financial and non-financial risks), CRO teams, risk stewards and 1LOD to ensure strong adoption and practical usability of ERM frameworks in day‑to‑day decision making.

• Represent ERM methodologies in governance and decision forums.

• Create and refine key risk and performance indicators for ERM programs, enabling better visibility on program effectiveness, maturity and trends.

• Communicate clearly and regularly about ERM methodology initiatives and projects with a wide variety of stakeholders (risk teams in different countries, financial risk functions, internal audit, leadership, product and platform).

What we're looking for (Minimum qualifications)

• Solid experience in Enterprise Risk / Operational Risk / Non‑Financial Risk, with hands‑on ownership of at least one major program or framework (RCSA, control testing, Issue Management, NP&F or equivalent enterprise‑level framework).

• Proven track record as a senior individual contributor leading complex risk initiatives end‑to‑end, from design to rollout, with limited oversight.

• Experience working in multi‑geo or global environments, balancing global standards with local regulatory expectations.

• Strong ability to translate risk methodologies into systems and data (platform requirements, data models, workflow design) in partnership with engineering and product.

• Demonstrated stakeholder management and influence without formal authority, especially across product, risk, compliance and platform/engineering teams.

• Comfort working with data and analytics (e.g., querying datasets, interpreting dashboards, defining metrics) to guide decisions on methodology and program performance.

• Experience defining and tracking metrics, SLAs and KPIs for risk/controls or governance processes.

• Strong written and verbal communication in English, including the ability to explain complex risk concepts to non‑experts.

Nice to Have

• Prior experience in ERM, operational risk, internal controls in financial services or fintech.

• Previous work in designing frameworks, methodologies and governance for risk (financial and/or non‑financial), influencing multiple lines of defense and senior stakeholders across geos.

• Exposure to AI/ML or advanced analytics applied to risk, controls, data quality or governance (e.g., LLMs, anomaly detection, smart suggestions).

• Experience working closely with platform / GRC / risk systems (e.g., JIRA‑based workflows, custom risk platforms, governance tooling).

• Familiarity with regulatory expectations for risks and governance in Brazil and/or other key markets, including reading requirements and translating them into practical frameworks.

• Background in high‑growth tech/fintech environments, navigating the tension between speed, innovation and robust risk management.

The Opportunity

This is a senior technical client leadership role that blends deep hands-on ML expertise with strategic advisory and consulting skills. You will be the most experienced ML voice across a diverse and expanding book of customer engagements — from early-stage companies bringing ambitious ML ideas to market, to established enterprises modernizing how they build and operate AI systems on AWS.

You will shape strategy, influence architecture, and leave every team you touch better than you found it. You bring the scientific depth to design and evaluate models rigorously, the engineering depth to architect production ML systems at scale, and the consulting instincts to translate both into business value for customers.

If you have led the hard conversations, shaped the architecture decisions that mattered, and built the things others benchmark against — and you are looking to do that across a growing portfolio of varied and interesting customers — this is the role for you.

What You'll Do

• Lead end-to-end ML assessments across infrastructure, data pipelines, model lifecycle, and organizational readiness — producing recommendations that drive executive decision-making and earn Caylent the next engagement.
• Partner with sales and solutions teams through the proposal and scoping phase, contributing the technical depth needed to shape well-grounded statements of work.
• Serve as the senior technical authority on client engagements — possibly across multiple projects simultaneously — providing architectural guidance, ensuring technical quality from your project team members, and getting hands-on when the engagement demands it, without owning day-to-day implementation responsibilities.
• Own or orchestrate high-quality POCs that give customers confidence before committing to a larger initiative.
• Advise customers on ML operations standards and architecture — covering MLOps pipeline design, model lifecycle management, LLMOps patterns, and production monitoring frameworks — translating operational complexity into decisions and guardrails their teams can own and sustain.
• Shape how Caylent wins its most technically complex opportunities — contributing the architectural thinking and credibility that turns prospects into customers.
• Strengthen the ML practice from the inside — through peer guidance, technical interviews, and contributions to accelerators, reference architectures, and thought leadership content.

What You Bring

The non-negotiables

• 10+ years in machine learning or AI, with a proven track record of leading client-facing engagements in a consulting or advisory capacity.
• Deep, current knowledge of the AWS ML and GenAI ecosystem, with the ability to make and defend architectural decisions across the full ML lifecycle — from data and feature engineering through training, deployment, and monitoring.
• Deep expertise in at least two or three ML domains — whether traditional ML, computer vision, NLP, time series, or others — combined with the judgment to assess, architect, and advise across the broader ML landscape.
• Proven ability to architect and govern production ML systems end-to-end, translating MLOps, LLMOps, and broader AI operations complexity into standards and decisions that engineering teams can execute and executives can act on.
• Deep expertise across foundation model adaptation — fine-tuning (LoRA, QLoRA, PEFT), alignment (RLHF, DPO), inference optimization (quantization, vLLM), and distributed training (DeepSpeed, FSDP) — combined with RAG and agentic system design, including multi-agent architectures, event-driven workflows, MCP integration, and human-in-the-loop patterns on AWS. Technical authority to prescribe the right approach and set architectural standards that teams can execute against.
• Proven ability to operate independently in complex customer environments — navigating ambiguity, aligning stakeholders, and translating ML tradeoffs into business risk and value for both technical and executive audiences.

Strong differentiators

• AWS Certified Machine Learning – Specialty and/or AWS Certified Solutions Architect – Professional.
• Experience shaping practice-level standards, reference architectures, and reusable ML accelerators across multiple engagements.
• Exposure to varied industries and problem types in a consulting or client-facing context.
• Deep fluency in responsible AI practices — model evaluation, bias detection, fairness frameworks, and AI governance — applied in enterprise deployments.
• Hands-on experience designing and deploying SRE agents and AI-driven operations workflows in production — spanning automated incident detection, triage, and remediation — with the ability to integrate across observability platforms and translate AI operations outcomes into measurable business value.

Technical Stack

Our practice spans a broad range of ML domains. Candidates are expected to prescribe — not just recognize — with the judgment to maximize what AWS makes possible and the experience to know how open-source tooling strengthens it.
