<\/span><\/span><\/b>\n <\/div>\n
\n The role of Senior Developer will have a technical focus on enabling Notifications at the enterprise level and supporting a robust communication platform for customer and crew portfolios. This is a hands\-on senior individual contributor role. This is not a management role. The expectation is to actively design, code, debug, optimize, deploy, and support production\-grade solutions.<\/span>
<\/span><\/span>\n <\/div>\n
\n
<\/span><\/span>\n <\/div>\n
\n Design AND implement core services for the enterprise Notifications platform, including APIs, event\-driven integrations, orchestration components, templates, and platform capabilities.<\/span>
<\/span><\/span>\n <\/div>\n
\n
<\/span><\/span>\n <\/div>\n
\n Write, review, debug, and optimize production code actively; lead through hands\-on engineering contribution rather than delegation.<\/span>
<\/span><\/span>\n <\/div>\n
\n

\n Prototype, validate, and productionize AI\-enabled features while considering latency, accuracy, cost, monitoring, fallback design, and operational reliability.<\/span>
<\/span><\/span>\n <\/div>\n
\n
<\/span><\/span>\n <\/div>\n
\n Design solutions for high availability, scalability, resiliency, observability, performance, security, privacy, and compliance needs.<\/span>
<\/span><\/span>\n <\/div>\n
\n
<\/span><\/span>\n <\/div>\n
\n Support integrations with internal enterprise systems, eventing platforms, data providers, communication providers, and vendor\-managed services as needed.<\/span>
<\/span><\/span>\n <\/div>\n
\n
<\/span><\/span>\n <\/div>\n
\n Troubleshoot and resolve complex production issues directly, including performance bottlenecks, integration failures, data issues, and system reliability concerns.<\/span>
<\/span><\/span>\n <\/div>\n
\n
<\/span><\/span>\n <\/div>\n
\n Work closely with architects, product owners, business stakeholders, development teams, and vendor teams to convert requirements into working solutions.<\/span>
<\/span><\/span>\n <\/div>\n
\n
<\/span><\/span>\n <\/div>\n
\n Contribute to technical design, system documentation, code reviews, automated testing, CI\/CD pipelines, release readiness, and production support practices.<\/span>
<\/span><\/span>\n <\/div>\n
\n
<\/span><\/span>\n <\/div>\n
\n Ensure solutions are aligned with enterprise engineering standards, security expectations, and application lifecycle best practices.<\/span>
<\/span><\/span>\n <\/div>\n
\n
<\/span><\/span>\n <\/div>\n
\n Mentor developers through code\-level guidance, design reviews, and engineering best practices; however, the primary expectation remains hands\-on delivery.<\/span>
