About the Role

As a Financial Systems Integrations Engineer, you’ll design, build, and optimize the integrations that connect OpenAI’s finance technology ecosystem. You’ll translate business needs into resilient, well-architected data flows and automations across a diverse set of internal and external systems. You’ll partner closely with Finance, IT, and other cross-functional teams to understand end user requirements and translate needs into solutions that are scalable, secure, and maintainable by applying sound engineering practices. You’ll use your knowledge of API design, data modeling, event-driven architecture, and integration best practices to deliver cutting-edge solutions to our partner teams.

This role combines hands-on technical execution with strategic impact, driving reliable, scalable, and compliant integrations that support OpenAI’s growth and financial operations.

This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.

In this role, you will:

• Design and implement robust automations and integrations that connect financial systems and data sources, using modern integration frameworks, APIs, and event-driven patterns.

• Translate business workflows into technical solutions that ensure accuracy, scalability, and maintainability across OpenAI’s finance technology stack.

• Partner with Finance, IT, and Engineering stakeholders to design data pipelines, system interfaces, and integration strategies that support ongoing team initiatives.

• Diagnose and resolve integration and platform issues, including data synchronization errors, API failures, and performance bottlenecks, while continually improving observability and error handling.

• Establish proactive monitoring and alerting practices to ensure integration health and compliance,while improving reliability and performance.

• Document integration architectures, migration runbooks, and technical processes to promote transparency, maintainability, and long-term team growth strategy.

• Support SOX compliance initiatives by embedding security, segregation of duties, and audit-readiness into integration design.

• Support functional testing, UAT, and data validation during system migrations and releases.

You might thrive in this role if you have:

• 8+ years of experience in enterprise integrations or automation solutions within complex business system environments.

• Experience working with integration platforms such as Oracle Integration Cloud (OIC) and architecting integration orchestrations

• A strong background in integration architecture, including building scalable, reusable frameworks with thoughtful monitoring, error handling, and recovery patterns.

• Proficiency in data modeling and API integration concepts, including REST, JSON, and event-based or message-based architectures.

• A solid understanding of accounting and financial domains, including billing, revenue recognition, financial close, and multi-entity consolidation.

• Hands-on experience with parallel run operations, reconciliation processes, and migration validation techniques.

• Excellent documentation skills and ability to produce migration runbooks, technical specs, and system diagrams.

• Familiarity with SOX compliance frameworks, secure system design, and audit readiness practices.

• Experience in fast-paced, hypergrowth, or multi-entity international organizations where scalability and reliability are critical.

• A curiosity-driven approach to technology, and a willingness to evaluate tools and frameworks based on fitness to purpose.
