Principal Solution Architect, Enterprise API Platform

Principal Solution Architect, Enterprise API PlatformPosition Overview:The Principal Solution Architect, Enterprise API Platform, is responsible for defining, scaling, and governing enterprise-wide or business solution architecture across platforms, domains, and delivery teams. This role shapes how technology solutions are designed, integrated, secured, and operated consistently across the organization. While architecture is foundational, the Principal Solution Architect will be responsible for designing solutions in close collaboration with the business and technology stakeholders. Where applicable, the role will be accountable to build solutions that scale and algin to business and technology requirements.Operating at an enterprise or portfolio level, the Principal Solution Architect focuses less on individual solution delivery and more on establishing architecture patterns, standards, guardrails and building solutions that enable teams to deliver high-quality, scalable, and secure solutions at speed.This role operates within a federated Enterprise Architecture (EA) model, partnering closely with business technology and platform teams to shape solutions in real time while improving accountability, speed, and delivery alignment. The architect remains connected to the central EA core through enterprise standards, governance, communities of practice, and cross-functional collaboration to ensure consistent, risk-aware technology decisions across domains.This role partners closely with Enterprise Architecture, Engineering, Product, Cybersecurity, and Platform teams to ensure solutions align to business strategy, are resilient and compliant, and can scale across multiple use cases—without becoming a bottleneck to delivery.For the Enterprise API Platform, this role serves as the strategic and technical architecture partner to the Head of Enterprise API Platform, helping translate API modernization and transformation objectives into practical, value-generating modernization decisions, reusable architecture patterns, MCP-enabled platform direction, and executable engineering outcomes.You Will (Key Responsibilities):Own and shape enterprise or business solution architecture strategy, standards, and patterns across multiple platforms and domainsDefine and maintain reference architectures and reusable design patterns (“golden paths”) for solution deliveryEstablish architectural guardrails that enable scalable, secure, and consistent solution design across teamsOwns reusable solution patterns, reference architectures, golden paths, and cross-team design consistencyWork with Solution Architects to drive adoption; Head of Portfolio Architecture to tailor for BU context; Principal Enterprise Architect to align with enterprise standardsLead enterprise-level or business-level design decisions for complex, high-impact initiatives that span multiple value streams or business unitsProvide architectural oversight and guidance across portfolios, ensuring alignment to enterprise standards and long-term strategyDrive early engagement on initiatives to identify cross-platform dependencies, systemic risks, and scalability constraintsPartner with Enterprise Architecture and platform teams to define build vs. buy guidance and integration patternsTranslate business and technology strategy into actionable architecture direction and solution designsPartner with Security, Risk, and Compliance teams to embed governance, security, and regulatory requirements into solution architectureDefine and promote best practices for operational resilience, scalability, performance, and maintainabilityEscalate enterprise exceptions / non-standard patterns / enterprise-risk decisionsInfluence and align stakeholders across engineering, product, and business leadership without direct authorityMentor and coach architects and senior engineers to elevate architectural maturity across the organizationRepresent solution architecture in enterprise forums, architecture review boards, and strategic technology discussionsInfluences Value Stream leaders, Product managers, Product Owners and Tech Leads to alignroadmaps, MVP scope, and technical trade-offs.Where applicable, the role will be accountable to build solutions that scale and algin to business and technology requirements.Available for production incidents with major impact to business operationsBalance strategic and tactical decisions across API modernization, API/MCP management, API lifecycle management, domain-aligned data models, reimplementation priorities, and AI-ready API capabilities.Continuously evaluate now versus later, strategic versus tactical, reusable versus disposable, and modernization versus value delivery, ensuring meaningful outcomes through thin slices rather than broad, low-value transformation efforts.Lead enterprise API architecture patterns, technical direction, and modernization alignment across API platform engineering, internal API delivery, external API delivery, and high-impact integration initiatives.Drive API rationalization, reuse, and domain alignment by helping teams redesign APIs around business capability-based, domain-aligned data models and solve common problems once rather than repeatedly.Guide reimplementation decisions for APIs coupled to non-performant or non-scalable data sources, balancing resiliency, scalability, maintainability, delivery urgency, and longer-term architectural direction.Help shape Guardian’s API, MCP gateway, and context-layer strategy so APIs become trusted, discoverable, observable, and governed inputs into agentic AI, reusable business capabilities, and future AI-native experiences.Serve as a critical daily and weekly architecture input to the Head of Enterprise API Platform, improving decision quality, decision velocity, modernization sequencing, and executive confidence in API transformation progress.Translate complex API architecture decisions into business outcomes, helping senior technology and business leaders understand “what this means” in terms of value, risk, scalability, execution, AI enablement, and strategic platform direction.Required Qualifications: You Have:Deep experience designing and governing enterprise-scale solution architectures across multiple teams and domainsExperience modernizing API ecosystems, including API management platforms, API lifecycle platforms, gateway patterns, integration patterns, performance and scalability improvements, and domain-aligned API design.Proven ability to define and drive adoption of architecture standards, frameworks, and reusable patternsStrong understanding of modern technology ecosystems (application architectures, APIs and delivery, integration patterns, AI, cloud platforms, and data flows)Experience balancing business priorities, technical trade-offs, and risk at an enterprise levelDemonstrated ability to operate at both strategic and hands-on levels when neededStrong experience influencing technical direction across distributed teams without direct reporting authorityAbility to bridge business and technology, translating strategy into clear architectural directionExcellent communication skills with the ability to convey complex concepts to both technical and non-technical audiencesExperience working in regulated or risk-sensitive environments with strong awareness of governance and compliance needsTrack record of mentoring architects and engineers and elevating organizational capabilitiesExperience collaborating withinAgile / product-based delivery models.Experience producingproduct-level and team-level technical design documentation.Strong engineering background with the ability to operate as a credible technical partner to engineering leaders while also shaping enterprise-level API architecture strategy.Demonstrated ability to balance pragmatic delivery with disruptive architectural thinking, including sequencing modernization work around prioritized strategic initiatives, high-visibility outcomes, and critical high-transaction-volume integrations.Strong understanding of MCP, agentic AI enablement, context-layer architecture, API observability, discoverability, governance, security, and the role of APIs as foundational inputs into AI-native enterprise capabilities.Location:Three days a week at a Guardian office in Holmdel, NJ < New York, NY
