Full-Stack Engineers serve as a frontline engineering owner for complex production and customer-impacting issues while building and improving our cloud-based platform end to end. This role combines hands‑on support - triaging incidents, reproducing problems, analyzing telemetry and data, communicating status, and driving issues through resolution - with full-stack delivery across web applications, APIs, services, integrations, and databases. This is an engineering role with meaningful production support responsibility, not a traditional help‑desk position.

The engineer is expected to translate incidents and recurring customer pain into durable code fixes, better observability, automation, and platform improvements.

• Own escalated, high-impact production and customer issues from intake through resolution, including triage, severity assessment, reproduction, containment, mitigation, root-cause analysis, and follow-up. Investigate issues across the full application stack using logs, traces, metrics, application code, API behavior, browser and service diagnostics, and database queries. Translate ambiguous customer symptoms into testable hypotheses, clear technical findings, and actionable next steps; provide timely updates to internal stakeholders and, when needed, customers.
  
  Use sound judgment when operating in production, following runbooks, least‑privilege practices, change controls, and escalation procedures to minimize operational risk. Produce high‑quality root‑cause analyses that explain what happened, why it happened, the impact, and the prevention plan; contribute to measurable improvements in time‑to‑mitigation and time‑to‑resolution.
• Design, develop, test, and maintain platform capabilities across modern web interfaces, backend APIs, microservices, integrations, and data-access layers. Build maintainable frontend experiences using JavaScript or Type Script and a modern framework such as Angular or React, connecting them to secure, well‑designed APIs and services. Develop and debug backend services using C# and .NET, applying sound design patterns and engineering practices for performance, scalability, resilience, and maintainability.
  
  Create, optimize, and maintain data structures, SQL queries, and data flows that support reliable application behavior and high‑performance processing. Integrate external services and APIs to extend platform functionality and interoperability.
• Implement safe, durable fixes for production defects, including defensive code, improved error handling, stronger validation, enhanced logging, and automated recovery or monitoring where appropriate. Proactively monitor platform health, identify emerging risks, and improve observability through useful dashboards, alerts, logs, traces, and metrics. Create and maintain runbooks, technical documentation, and knowledge articles that improve support readiness and reduce repeat incidents. Participate in the team's production support and incident response rotation as required.
• Implement and maintain secure development practices that protect sensitive data and support applicable privacy and compliance requirements, including HIPAA and HITRUST expectations. Write well‑tested, maintainable code; participate in code reviews; and follow established standards for source control, CI/CD, deployment, and change management.
