Full-Stack Engineer

Design Build & Maintain Integrated Internal Applications

• Own the end-to-end lifecycle of internal software applications and integrations: architecture coding testing deployment and maintenance.

• Translate business requirements into robust scalable technical designs including data models APIs system architecture and UI flows where relevant.

• Implement full-stack features: write clean efficient and maintainable code for both back-end and front-end components; design and manage persistence layers; integrate with thirdparty APIs (e.g. Salesforce Stripe) and internal services.

• Build security & compliance into the design incorporating data protection and regulatory requirements (e.g. GDPR) from the start and collaborating with IST ITOps and Legal to ensure adherence to standards.

Act as a Technical Partner to Business Stakeholders

• Collaborate with business stakeholders (e.g. Finance Sales HR Business Technology colleagues) to clarify requirements challenge assumptions and codesign pragmatic valuedriven solutions.

• Support and guide User Acceptance Testing (UAT): provide technical support during UAT address defects quickly and ensure the delivered solution truly solves the underlying business problem.

• Communicate clearly on feasibility tradeoffs and timelines serving as the technical point of contact and managing scope to protect solution integrity and production stability.

Own the Full Development & Operational Lifecycle

• Implement and operate CI/CD pipelines to achieve reliable frequent releases with a low changefailure rate.

• Write and maintain unit integration and endtoend tests to ensure high software quality and reduce regressions.

• Provide ongoing production support for the applications you own including bug fixes performance tuning refactoring to address technical debt and planned feature evolution based on user feedback and strategy.

• Document architecture and decisions clearly (e.g. in Confluence/Xtranet and Atlas) so the broader team can understand operate and extend your work.

Ensure System Health Monitoring & Incident Response

• Implement comprehensive monitoring and alerting for all owned applications with meaningful KPIs and dashboards that surface issues before they become incidents.

• Serve as the primary oncall engineer (as part of a rotation) for your applications leading incident investigation and coordinating with other teams when issues occur.

• Run blameless postmortems after critical incidents identify root causes and define action items that meaningfully reduce recurrence.
