• 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.
• Support CI/CD, debugging, production issue resolution, and continuous improvement of internal systems.

• 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.
• Experience in financial services, regulated environments, or other high‑reliability domains is a plus.
