Overview

Our client, a leading organization in the insurance and risk industry, is seeking a Senior Engineer – Integration & API Architecture Consultant to lead enterprise integration architecture and API enablement initiatives across multiple work streams.

This is a senior, hands-on technical leadership role ideal for an engineer who thrives in highly autonomous environments, can navigate ambiguity, and has a proven track record of designing and implementing modern API and integration architectures at scale.

The consultant will establish integration standards, govern API design, implement secure data exchange patterns, and partner closely with engineering and data architecture teams to drive enterprise-wide integration strategy.

Key Responsibilities

API & Integration Architecture

• Own the enterprise API and integration intake process, including intake, triage, prioritization, and execution.
• Design, define, and enforce enterprise API contract standards across REST and event-driven architectures.
• Establish scalable integration patterns supporting synchronous APIs and event-driven messaging.
• Ensure API and integration contracts align with enterprise canonical data models.

Platform & Integration Engineering

• Configure, administer, and optimize API gateway technologies such as Gravitee (or similar platforms including Apigee or Mule Soft).
• Design and support integrations utilizing Workato or comparable iPaaS/orchestration platforms.
• Build and support event streaming solutions using AWS MSK/Kafka.
• Contribute to workflow orchestration using Temporal or comparable durable execution frameworks.

Security & Governance

• Design and implement secure integration boundary controls.
• Implement tokenization strategies for sensitive data (PII/NPI) to protect lower environments.
• Enforce API governance standards, authentication, authorization, and enterprise integration best practices.
• Partner with enterprise data architecture to ensure consistency across integration contracts.

Technical Leadership

• Serve as a hands-on technical leader and subject matter expert.
• Provide architectural guidance while remaining actively involved in implementation.
• Help engineering teams overcome technical challenges through pragmatic decision making.
• Operate independently in a fast-paced environment with minimal direction.

Required Qualifications

• Extensive experience designing and implementing enterprise API ecosystems and integration architectures.
• Deep expertise with REST APIs, API contract design, and event-driven architectures.
• Strong experience with API gateway technologies, including policy management, rate limiting, and access control.
• Experience with Gravitee, Apigee, Mule Soft, or comparable API management platforms.
• Hands-on experience with Workato or similar iPaaS/integration orchestration tools.
• Strong knowledge of OAuth2 and OpenID Connect authentication standards.
• Experience implementing tokenization and sensitive data protection using solutions such as Protegrity, Token Ex, or similar technologies.
• Hands-on experience building event-driven integrations using Kafka or AWS MSK.
• Proven ability to establish standards and lead technical initiatives with minimal oversight.
• Excellent communication and collaboration skills across technical and business teams.

Preferred Qualifications

• Experience with Temporal or similar workflow orchestration platforms.
• Experience designing or consuming enterprise canonical/logical data models.
• Familiarity with Master Data Management (MDM) concepts.
• Exposure to AI agent orchestration, Lang Graph, or agentic workflow frameworks.
• Prior experience working in enterprise insurance or financial services environments is a plus.
