* Keep us up to date by continuously updating our technologies and patterns.
* Drives adoption and governance of approved AI-assisted engineering practices
across teams to improve code quality, delivery speed, and operational
outcomes (e.g., AI-assisted code review/refactoring, test acceleration,
release readiness, incident/root-cause analysis), while establishing
measurable validation standards (secure coding, peer review, automated
testing) and promoting reuse of proven patterns and automation within the
SDLC/TLM toolchain.
* Applies knowledge of tools within the Software Development Life Cycle
toolchain, including approved AI-assisted development and automation
capabilities, to improve the value realized by automation at scale.

iterative approach to achieving our long term goals
* Demonstrated experience leading effective use of enterprise-authorized
AI-assisted software development tools within the work environment (e.g., for
coding, code review, test acceleration, troubleshooting) with the ability to
set team expectations for validating AI outputs for correctness, performance,
and security
* Strong understanding of responsible AI use in engineering workflows,
including data sensitivity considerations, secure handling of inputs/outputs,
and adherence to resiliency and security expectations; experience coaching
senior engineers/leads on compliant usage patterns and controls.

 

Technologies:

* We primarily use Jvm based languages (Java/Kotlin) but we also have parts of
the platform that use other languages as needed.
* We look to use Open source when it makes sense and build ourselves when it
doesn't.
* We are entirely cloud native and want to build a truly multi-cloud solution.
* We look at each problem independently and pick the right technology to solve
it.

* We aren’t afraid to try new things but we always remember that we are looking
to build something to last, and we focus on solving real world problems for
real life customers.
