  • Drive architectural design for scalable, modular services and APIs supporting high-volume operational workflows.
  • Partner with Product and Architecture to decompose monolithic applications into well-defined domains and services.
  • Define and implement modern data-access patterns using ORMs, repository patterns, and controlled schema migrations.
  • Improve system performance, resilience, and fault tolerance through sound design practices (timeouts, retries, idempotency, and graceful degradation).
  • Establish and enforce engineering standards for code quality, testing, and maintainability.
  • Embed observability into applications using structured logging, metrics, and distributed tracing (OpenTelemetry).
  • Design secure-by-default application patterns including authentication, authorization, secrets management, and secure coding practices.
  • Lead technical discovery and solution design for complex, cross-team initiatives.
  • Mentor senior and mid-level engineers through design reviews, code reviews, and hands-on technical guidance.
  • Support and coordinate “level 3” incidents including after hours as necessary.
  • Collaborate closely with Infrastructure, Security, Data, and Operations teams to ensure solutions meet operational and compliance requirements.

Requirements

  • 8+ years of professional software engineering experience, with significant time spent modernizing large-scale applications.
  • Demonstrated experience operating at a Staff or Principal Engineer level, influencing architecture and technical direction.
  • Deep expertise in C#, .NET, .NET Core, and modern application development practices.
  • Strong experience designing RESTful APIs and service-oriented or domain-driven architectures.
  • Hands-on experience modernizing legacy systems and databases in production environments.
  • Strong understanding of relational databases and modern data-access strategies.
  • Experience with cloud platforms (Azure preferred) and cloud-native application patterns.
  • Excellent communication skills with the ability to clearly explain technical tradeoffs to engineering and business stakeholders.
  • Proven ability to lead through influence, mentor engineers, and raise overall engineering quality.
