About The Position

Baker Tilly is seeking a Principal Platform Engineer to lead the design, development, and operation of its AI agent integration framework within the APG platform. The role establishes scalable, secure, and standardized capabilities to connect third-party AI agents to the firm’s technology ecosystem while maintaining control of enterprise data, decision history, and learning. It defines vendor integration standards, builds event-driven interfaces and data ingestion pipelines, and supports interoperability, portability, and production readiness across AI-enabled solutions. As a foundational member of the Platform & Production Engineering team, the engineer partners with architecture, engineering, data platform, procurement, legal, and vendor teams to translate requirements into production-ready solutions. The role calls for deep expertise in platform engineering, API and event-driven architectures, vendor integration, and observability, together with hands-on development skills and the ability to establish technical standards in an evolving AI environment.

Requirements

Bachelor's degree in Computer Science, Engineering, or a related field.
10+ years of progressive experience in platform engineering, systems integration, or related software engineering disciplines, including development and support of production-scale enterprise solutions.
Demonstrated experience designing, building, and operating event-driven integration architectures, including publish/subscribe messaging, webhooks, API platforms, and distributed systems.
Strong hands-on programming experience with Python and/or TypeScript, including recent development, testing, and maintenance of production-quality code.
Experience developing vendor-facing technical specifications, establishing integration standards, and holding external engineering teams accountable for requirements and acceptance criteria.
Deep understanding of API design, versioning, contract testing, integration patterns, and agent interoperability technologies, including Model Context Protocol (MCP).
Experience implementing identity management, authentication, authorization, entitlements, and permissible-use controls in enterprise integration environments.
Experience building telemetry, event processing, and data ingestion pipelines integrated with modern enterprise data platforms, including Databricks or comparable lakehouse technologies.
Strong knowledge of observability, monitoring, logging, distributed tracing, incident management, and rollback strategies for production systems and third-party integrations.
Experience designing integration architectures supporting vendor portability, system interoperability, data ownership, and replacement of third-party technology components.
Strong technical problem-solving and troubleshooting skills, including diagnosing complex integration issues and implementing scalable, reliable solutions.
Ability to collaborate effectively with enterprise architects, product and engineering leaders, procurement teams, and external technology vendors.
Excellent written and verbal communication skills, including technical documentation, explaining complex engineering concepts, and influencing technical decisions across stakeholder groups.
Experience working with globally distributed engineering teams and coordinating activities across functions and geographic locations.
Ability to work independently, manage competing priorities, and deliver high-quality technical solutions in a fast-paced, evolving environment.
Proficiency in leveraging AI-assisted and agentic development tools to improve engineering productivity, accelerate development, and enhance solution quality.
No professional certifications or licenses are required.
