Job Description:

As a Principal Software Engineer on the Platform Integrations team, you will serve as the senior technical authority for the integration backbone of the Certent Equity Management (CEM) platform — the suite of services responsible for moving data in and out of the system across file-based transfers, REST APIs, broker interfaces, and partner integrations. You will lead one of two Platform Integrations teams, partnering closely with a peer Principal Engineer who leads the second team — both reporting to a shared Engineering Manager and jointly owning the integration platform across multiple independent production ecosystems.

This is a pure IC role. Your job is to write great code, make sound architectural decisions, and elevate the technical quality of everything your team touches. You will be the go-to technical voice for a set of mission-critical services that handle financial data — where correctness and reliability are non-negotiable.

The integration platform is at an active modernization inflection point. You will be driving the migration of business logic out of legacy systems into modern, maintainable .NET services — while keeping production stable across multiple client ecosystems simultaneously. The right candidate sees legacy modernization not as a burden but as the most technically interesting work in the org.

You will bring an AI-first mindset — genuinely integrating agentic development tooling into your daily workflow and setting the standard for your team.

• Serve as the senior technical authority for the Platform Integrations service suite — owning the architecture of services responsible for file-based transfers, REST APIs, broker data interfaces, partner integrations, and background data processing pipelines.
• Own architectural decisions across the integration platform: connector patterns, API design, data access strategies, queue-based processing, and service decomposition.
• Assess and improve the reliability of integration services running on lift-and-shifted Azure infrastructure — identifying where legacy on-premises patterns are creating fragility in a cloud environment and driving targeted improvements.
• Evaluate and recommend cloud-native Azure patterns for data movement — including blob storage, event-driven messaging, and API hosting modernization — as the platform evolves beyond its initial lift-and-shift state.
• Drive the active migration of business logic out of legacy integration platforms into modern .NET services — reading, understanding, and faithfully re-implementing existing integration processes with improved reliability and maintainability.
• Lead the modernization of legacy service patterns toward REST and evaluate paths toward containerized or cloud-native deployment.
• Evaluate and drive strategic improvements: connector abstraction simplification, stored procedure migration to application tier, API versioning strategy, resilience patterns, and security hardening.
• Ensure production stability across multiple independent deployment ecosystems — understanding the implications of shared codebases with ecosystem-specific configurations and data isolation requirements.
   

• Write, review, and contribute production-quality code across the integration stack — C#/.NET 8, Oracle SQL/PL/SQL, REST API design, file processing pipelines, and background job frameworks.
• Debug complex issues that span C#/.NET and Oracle PL/SQL boundaries — the hardest production bugs live at this layer.
• Design and optimize complex Oracle SQL — including multi-join queries, stored procedures, execution plan analysis, indexing strategies, and read-optimization patterns for high-volume data operations.
• Implement and improve observability across services — structured logging, distributed tracing, health checks, and operational alerting for data pipeline failures.
• Establish and enforce testing standards across the integration platform — unit, integration, and contract tests for broker interfaces.
   

• Champion ≥50% AI-authored PR targets and ≥95% AI code review adoption as organizational minimums.
• Model an agentic development mindset — integrating AI tooling into your own daily workflow and actively coaching teammates to do the same.
• Push the team beyond baseline AI adoption into workflows and practices that measurably improve delivery velocity and integration quality.
   

• Set the technical bar for the team — establishing coding standards, architectural patterns, and engineering practices that the rest of the team can follow.
• Mentor engineers who may be less familiar with Oracle, financial domain concepts, or integration patterns — teaching through code review, pair programming, and design sessions.
• Partner with the peer Principal Engineer to align on technical direction, share ownership of the integration platform, and build consistent patterns across both teams.
• Interface with client stakeholders as needed — requirements clarification, integration design discussions, and issue resolution.
• Contribute to cross-team technical forums alongside Principal Engineers, the Solution Architect, and Engineering Managers.

• 8+ years of hands-on software engineering experience in enterprise SaaS environments, with demonstrated experience as a Principal or Senior Principal Engineer.
• Deep expertise in C# and .NET (Framework and modern .NET 6+/8) — able to work fluently across both legacy ASP.NET and modern ASP.NET Core codebases simultaneously.
• Strong Oracle Database and PL/SQL proficiency — complex multi-join SQL, stored procedures, packages, triggers, execution plan optimization, and performance tuning at enterprise scale.
• Proven experience with file-based integration patterns — CSV, fixed-width, XML, Excel parsing, PGP encryption, SFTP, and archive management at production scale.
• Experience designing and maintaining REST APIs with clean layered architecture — strict separation across API, business logic, data access, domain, and DTO layers.
• Experience with multi-tenant data isolation patterns — understanding the security implications of tenant-scoped data access in a shared codebase.
• Hands-on Azure cloud experience — with the ability to assess, stabilize, and modernize integration services running on lift-and-shifted Azure infrastructure, and evaluate cloud-native alternatives to legacy on-premises integration patterns.
• Demonstrated legacy modernization experience — ability to read, understand, and incrementally migrate complex legacy systems without big-bang rewrites.
• Experience with connector/plugin architectures — factory patterns, template method patterns, and the discipline to extend without destabilizing existing production connectors.
• Experience with queue-based processing — retry logic, state machine transitions, concurrency, failure modes, and dead-letter handling.
• Demonstrated AI-first engineering mindset — hands-on experience with agentic development tooling and a track record of driving AI adoption within an engineering team.
• Strong observability and operational excellence mindset — structured logging, distributed tracing, alerting, and health monitoring for data pipeline services.
• Fluent communicator — able to engage with client stakeholders and translate complex integration realities clearly.
• Experience managing production systems across multiple independent deployment environments.
• Bachelor's degree in Computer Science, Engineering, or equivalent work experience.
   

• Direct experience with Boomi or similar enterprise iPaaS platforms — specifically the ability to read and migrate existing integration processes into custom .NET services.
• Experience with Hangfire or similar background job scheduling frameworks in production environments.
• Familiarity with containerization (Docker, Podman) and evaluating migration paths toward cloud-native deployment.
• Experience with WCF/CoreWCF and SOAP-to-REST migration strategies.
• Experience modernizing file-based and API-based integration patterns from on-premises to cloud-native Azure equivalents — Azure Blob Storage, Azure Service Bus, or similar.
• Background in financial services, equity compensation, broker-dealer integrations, or adjacent regulated domains — including familiarity with ESPP, RSU/RSA, stock option exercises, tax withholding, and broker data interfaces.
• Experience with Azure DevOps CI/CD pipelines, NuGet package management, and enterprise build/deploy practices.
• Experience with security hardening of integration services — secrets management, credential vaulting, encryption in transit, and API authentication patterns.
