- 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.
- Collaborate closely with Infrastructure, Security, Data, and Operations teams to ensure solutions meet operational and compliance requirements.
Qualifications
- 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.
Bonus Experience
- Experience with high-throughput, transaction-heavy operational systems.
- Exposure to event-driven or asynchronous architectures.
