Job Description

Job Title: Sr. Systems Manager – BaaS Platform (C# / .NET / Azure)
Location: Pasadena, CA (On-site)
Employment Type: Contract (W2 through ZipStaff — No C2C or 1099)

About the Opportunity

ZipStaff is seeking a highly skilled Senior Software Engineer to join the Banking-as-a-Service (BaaS) team at a leading fintech and embedded finance organization.
In this role, you will design, build, and support scalable, secure, high-performance systems that enable partner onboarding and embedded financial services across a broader partner ecosystem. This is a hands-on engineering role with technical leadership expectations — not a people-management or traditional systems-administration role.

What You’ll Do

  • Design and develop APIs and microservices that support BaaS onboarding and partner integration
  • Collaborate with product managers, architects, and engineering teams to define technical requirements and deliver robust solutions
  • Support engineering excellence through code reviews, mentoring, and best practices in CI/CD, testing, and observability
  • Ensure compliance with SLA standards and contribute to monitoring and alerting systems
  • Participate in incident response and root-cause analysis to improve system reliability
  • Draft architectural and design documentation to support design options analysis and decision-making
  • Evaluate emerging technologies for applicability, feasibility, and adoption paths
  • Refactor and extend the existing codebase to fix defects and add features/functionality
  • Build durable, flexible systems that favor configurability over customization

Required Qualifications

  • 5+ years of software engineering experience, including at least 1 year in a technical leadership role
  • Strong portfolio of work developing secure, standards-compliant code across multiple platforms
  • Proficiency in C#, .NET, and SQL
  • Hands-on experience with Azure native services (APIM, Azure SQL, Cosmos DB, Key Vault), container technologies, and caching frameworks
  • Solid understanding of RESTful API design, OAuth2, and OpenAPI specifications
  • Familiarity with event-driven architecture (Service Bus, Event Hubs) and microservice-based patterns
  • Hands-on experience implementing observability dashboards and platforms (e.g., Datadog, Grafana)
  • Ability to work in a fast-paced environment delivering iterative, mission-critical, customer-facing applications
  • Deep knowledge of Git, DevOps, Agile Scrum, and security best practices in financial services
  • Familiarity with compliance standards such as PCI DSS and SOC 2
  • Ability to work on-site in Pasadena, CA
  • Must be authorized to work in the United States without sponsorship now or in the future

Preferred Qualifications

  • Prior experience in fintech or embedded finance platforms
  • Familiarity with partner onboarding workflows and SLA management
  • Contributions to open-source projects or technical publications
