We are seeking a highly skilled and motivated Senior Software Engineer to join our Banking-as-a-Service (BaaS) team, supporting partner onboarding and platform enhancement initiatives. This role will be instrumental in building and supporting scalable, secure, and high-performance systems that enable embedded financial services across a broader partner ecosystem.

Key Responsibilities

  • 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 the development of monitoring and alerting systems.
  • Contribute to incident response and root cause analysis to improve system reliability.
  • Draft architectural and design documentation to assist design options analysis and decision-making.
  • Evaluate emerging technologies from applicability to feasibility and adoption paths.
  • Refactor and extend the existing codebase to fix defects and add features/functionality.
  • Create durable and flexible systems by developing for change, favoring configurability over customization.

Required Qualifications

  • Strong portfolio of work showing experience developing secure and standards-compliant code across multiple platforms.
  • Proficiency in C#, .NET, SQL, and hands-on experience with cloud platforms (Azure native services such as APIM, Azure SQL, Cosmos DB, and Key Vault), container technologies, and caching frameworks.
  • Solid understanding of RESTful API design, OAuth2, and OpenAPI specifications.
  • Familiarity with event-driven (Service Bus, Event Hubs) and microservice-based architecture patterns.
  • Hands-on experience leveraging and implementing observability dashboards and platforms (e.g., Datadog, Grafana).
  • Ability to handle a fast-paced environment for iterative project turnarounds on mission-critical, customer-facing applications.
  • Deep knowledge of Git, DevOps, Agile Scrum, and security best practices in financial services and compliance standards (e.g., PCI DSS, SOC 2).

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.
