- 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.

- 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.
