What You’ll Do We are seeking a Senior Engineer to be the technical expert on our Business Applications team.

We partner with every department to provide the platforms, guardrails, and integrations that eliminate manual toil safely and efficiently. We own and administer Jira, Jira Service Management (JSM), Confluence, Rovo, Loom, Glean, and our citizen development platform, Workato. We hold ourselves to least-privilege access, data privacy, and auditable data flows in everything we build. In this role, you will partner with business teams to turn pain points into working solutions. You will gather requirements with empathy, apply human-centered, API-first, and secure-by-design principles, select the best-fit tooling from our stack (the Atlassian suite, Workato, custom AWS automation tooling, and our AI platforms), and own each solution end to end, from discovery through production support. This is an individual contributor role reporting to the Senior Manager, Business Applications. You will work alongside our IT Admins and AI Admins as their technical escalation point and mentor. This role will be responsible for: - Lead discovery with stakeholders across the company, using interviews and process walkthroughs to define the problem, who is affected, and how success will be measured - Translate pain points into scoped problem statements and recommend the best-fit approach (native feature, Workato, or custom automation), explaining tradeoffs in speed, maintainability, and risk - Design solutions using human-centered, API-first, event-driven, and secure-by-design principles, and document architecture decisions so others can support and extend them - Own solutions end to end: design, build, test, release, monitor, support, and retire - Build and maintain Workato recipes and connectors with resilient error handling, end-to-end monitoring, and auditable data flows - Build custom automation tooling and AWS middleware where native features and Workato cannot meet the requirement - Design and evolve complex workflows, custom fields, automations, and service management configurations in Jira, JSM, and Confluence beyond day-to-day administration - Architect and evolve our governed citizen development platform, Workato, including standardized frameworks, templates, reusable connectors, service accounts, and sandboxes, and review team-built
