Position Summary

We are looking for a highly experienced Principal Software Engineer with deep expertise in .NET technologies and a strong background in designing scalable, resilient, and high-performance service solutions. In this role, you will define the architectural vision for our loan and lease servicing platform, ensuring reliability, security, and efficiency at scale. You will collaborate closely with leadership, product, and engineering teams to develop and execute on a strategic technical roadmap, mentor engineers, and tackle complex challenges to enhance our servicing platform.

As a Principal Engineer, you will drive key technical decisions, lead mission-critical initiatives, and shape the evolution of our servicing solutions to support our rapid growth and industry leadership.

Key Responsibilities

Lead the design and development of enterprise-scale, mission-critical loan and lease servicing solutions using .NET (C#) and modern cloud-based architectures.

Architect highly scalable, fault-tolerant, and secure servicing platforms that support a large volume of financial transactions and workflows.

Provide technical leadership across teams, guiding decisions on architecture, design patterns, and engineering best practices.

Collaborate with product and engineering leadership to align technical solutions with business objectives and regulatory requirements.

Drive cross-functional initiatives to enhance system performance, reliability, and maintainability.

Ensure compliance with industry regulations, data security standards, and best practices in financial services.

Mentor senior and mid-level engineers, fostering a culture of technical excellence, knowledge sharing, and continuous improvement.

Evaluate and implement emerging technologies and tools to drive innovation and operational efficiencies in our servicing platform.

Contribute to key architectural decisions, including microservices adoption, event-driven architecture, and API-first design principles.

Qualifications

10+ years of experience in software engineering, with a strong background in building scalable and resilient service solutions.

Expertise in .NET (C#) and modern backend development frameworks.

Experience designing and maintaining cloud-based infrastructure (Azure, AWS, or GCP) with a focus on scalability, security, and observability.

Strong expertise in distributed systems architecture, microservices, and event-driven workflows.

Hands-on experience with databases (SQL Server, PostgreSQL, or NoSQL) and data modeling for financial applications.

Experience with CI/CD pipelines, DevOps practices, and automation tools.

Ability to influence technical direction and work cross-functionally with product, engineering, and executive teams.

Strong leadership skills with a proven ability to mentor and lead engineering teams.

Excellent problem-solving and analytical skills, with the ability to thrive in a fast-paced, dynamic environment.

Bonus Points

Experience with financial servicing platforms, loan origination, or lease management systems.

Knowledge of regulatory and compliance requirements in financial services (e.g., PCI-DSS, SOC 2).

Experience managing technical debt and driving long-term architectural improvements.

Familiarity with modern frontend frameworks (React, Angular, or Blazor) is a plus.
