Sentinel Asset Inventory Lead

Role Summary

Sentinel is one of the eight Platforms forming the core of Pfizer’s artificial intelligence (AI) transformation. Sentinel provides a single front door to deploying and maintaining infrastructure and services. Its scope moves beyond the traditional hyperscalers such as Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform (GCP) and into the non-hyperscaler space, where the same front door can stand up a Supabase instance, a Grok agent, or whichever new capability arrives next. Sentinel does not stop at provisioning either: it takes on the agentic management of what has been deployed. Knowing precisely what has been deployed is the foundation that agentic management rests on. We are seeking a Sentinel Asset Inventory Lead, responsible for the delivery of the source of truth for all Sentinel deployed assets. This role demands attention to detail, an appetite for rigor in processes and an approach focused on data quality, accuracy and freshness. You will own the process design for data freshness and quality assurance that will encompass both agentic and human approaches, and you will be accountable for reporting drawn from data with a complex origin and real latency – reporting that has to be both accurate and timely. You will work very closely with the Cloud Infrastructure organization within the Chief Information Security Officer (CISO) function, which owns the ServiceNow Configuration Management Database (CMDB) that provides a core component of the asset inventory. The asset inventory extends the CMDB rather than replacing it, introducing new capabilities that specifically address the need for high volume and near real time performance, extensions to cover novel asset types, and metadata about assets that cannot reside in the CMDB. The role reports to the Senior Director, Engineering Lead, in an organization that runs up through the Vice President, Initiative Lead and the Chief Technologist to the Chief Information Officer (CIO). You will carry no colleague line management, and will lead one or more contract engineering resources who build the Asset Inventory technical capability. This role encompasses the end to end delivery of the Sentinel asset inventory, a component of the Sentinel platform, and is global in scope: the inventory covers every asset Sentinel deploys, across every business line Sentinel serves. The organizational lines you work across are those between Digital and the Cloud Infrastructure organization within the Chief Information Security Officer (CISO) function, and you will work across them and their stakeholders to communicate the vision and purpose of the Asset Inventory effectively, take part in technical, engineering level discussions and be perceived as credible in them. You will be accountable for the quality, accuracy and freshness of the record the wider platform depends on, creating clarity from ambiguity in an estate that changes continuously.

Role Responsibilities

In order of importance, indicate the primary responsibilities critical to the performance of the role. It is recommended not to list actual tasks but focus on 5-8 essential responsibilities that highlight accountability and level of judgment required.

Asset Inventory Leadership

You own the source of truth for all Sentinel deployed assets and the technical capability behind it:

• Source of Truth Ownership: You are accountable for the Sentinel asset inventory as the single authoritative record of every deployed asset, from the definition of what constitutes an asset through to the coverage, correctness and currency of what the inventory holds. You own the inventory’s data model: the contract engineers are responsible for building it, you are accountable for it being right.
• CMDB Extension: You define how the inventory extends the ServiceNow Configuration Management Database (CMDB) owned by the Cloud Infrastructure organization within the Chief Information Security Officer (CISO) function instead of duplicating it, introducing the capabilities the CMDB is not intended to carry: high volume and near real time performance, novel asset types, and metadata that cannot reside in the CMDB.
• Technical Credibility: This is a delivery leadership role, not a hands-on engineering one. You bring a working command of data modelling, schema design, reporting and performance considerations — enough to hold a real design discussion with the deep technical resources who write the code, to question an estimate, probe a design decision, and tell a considered answer from a plausible one. You communicate effectively with those engineers, and translate what they build accurately for stakeholders who are not technical.

Data Quality and Freshness

You own the processes that make the inventory trustworthy, and the standards against which its trustworthiness is judged:

• Process Design: You own process design for data freshness and quality assurance, encompassing both agentic and human approaches, and you decide deliberately which checks belong to automation, which belong to an agent, and which need a person, taking considered risks to advance the process where the conservative answer will not scale.
• Quality Standards and Measurement: You define what accuracy, completeness and freshness mean for each asset type, set measurable targets against them, instrument the inventory so those measures are visible, and hold the capability to them.
• High Churn Reconciliation: You establish the reconciliation practice that keeps the inventory honest in a complex, high churn estate: continuous comparison against source systems, detection of drift and orphaned or missing assets, and a clear route from an exception to its correction. DELIVERY You lead the build of the Asset Inventory technical capability and the delivery of the roadmap behind it:
• Roadmap Ownership: You own the delivery roadmap for the asset inventory, sequencing coverage of asset types and sources against the demand the platform places on it, anticipating consumers beyond Sentinel as the inventory matures — security and compliance among the most likely — and keeping the plan honest as priorities change.
• Contract Resource Leadership: You lead one or more contract engineering resources who build the Asset Inventory technical capability, setting technical direction, quality expectations and priorities, working alongside them through the development of the data model so that it meets the requirements of the asset inventory component, and ensuring the effort is appropriately resourced to meet the deliverables and timescale commitments.
• Dependency and Risk Management: You surface dependencies early — on the CMDB, on the systems that emit asset data, and on the teams that own them — and drive blockers to resolution with those teams, keeping affected stakeholders informed throughout. You exercise judgment in complex decisions and act independently on what you can see coming — a feed going stale, a source system changing shape — rather than waiting for a wrong number to surface it.
• Cross-Team Facilitation: You convene and run detailed technical working sessions with the Cloud Infrastructure organization and Sentinel engineering, taking them to real decisions rather than status updates, and you navigate the politics of aligning teams that carry their own priorities and commitments.

Reporting and Documentation

You are accountable for what the inventory reports and for the record of how it works:

• Reporting Accuracy and Timeliness: You understand the intricacies of reporting data that has a complex origin with latency, and you hold reporting to being both accurate and timely: figures that state their provenance and how current they are, and a regular, credible view of inventory coverage, quality and delivery health for platform, technical architecture and Digital leadership, including at Digital Leadership Team (DLT) level.
• Design, Decision and Lineage Records: You lead the capture of the
