Build and maintain APIs, service integrations, and backend functionality that support internal applications.

Create high-quality frontend experiences using modern web technologies, with attention to usability, performance, accessibility, and maintainability.

Contribute to shared engineering foundations such as common components, service patterns, observability integrations, and internal tooling.

Partner with product, operations, and engineering stakeholders to understand workflows, prioritize needs, and deliver practical solutions.

Help define and apply sound engineering standards across application design, testing, deployment, and operational support.

Collaborate with platform, infrastructure, and security teams to ensure systems are resilient, secure, and production-ready.

Preferred Experience

Experience building internal tools, workflow applications, or shared engineering capabilities.

Familiarity with frontend architecture, reusable component patterns, and design‑system‑style thinking, even if the role is not purely frontend‑focused.

Experience with observability, production support, and operational debugging across both frontend and backend systems.

Exposure to developer tooling, internal platforms, or service enablement work.

Experience with AI/LLM‑assisted workflows or internal automation is a plus.
