Senior Business Applications Engineer

We are seeking a Senior Engineer to be the technical expert on our Business Applications team. The Business Applications (BizApps) team is the operational backbone for organizational collaboration, system connectivity, and process automation at Horizon3 http://Horizon3.ai. 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 automations against established guardrails
• Enforce least-privilege access in every solution through role-based access control (RBAC), appropriate read/write scopes, and service accounts in place of individual credentials, partnering with Security and IT Engineering
• Serve as the technical escalation point for IT Admins and AI Admins, review their work, and mentor them toward engineering-level scope
• Partner with AI Admins and the Senior Manager to apply Glean, Rovo, Claude, Gemini, and Bedrock capabilities to complex business automation needs
• Write runbooks, design documents, and handoff materials that allow Admins to support what you build
• Report on delivery velocity, integration reliability, and adoption to the Senior Manager and stakeholders
• Demonstrate a commitment to integrity, process improvement, and customer satisfaction

What you’ll bring

• Must have demonstrated experience owning solutions from requirements gathering through production support, leading complex, high-impact projects with little to no supervision
• Must have hands-on experience building and maintaining integrations on an iPaaS platform (Workato strongly preferred), including error handling, monitoring, and secure credential handling
• Must have working knowledge of APIs, webhooks, data models, and REST and event-driven integration patterns, and the ability to write custom code or scripts where iPaaS cannot meet the requirement
• Must have hands-on experience engineering workflows, custom fields, and automations in Jira, JSM, and Confluence, or comparable work management and ITSM platforms
• Must have experience gathering requirements from non-technical teams and turning them into design documents and testable acceptance criteria
• Must have an understanding of RBAC, least-privilege access, service account practices, and data privacy as they apply to integrations and automations
• Must have experience mentoring more junior engineers or administrators through design guidance and work review
• Must be able to explain design decisions and tradeoffs clearly in writing to both technical and non-technical audiences

Required Tech Stack Experience

• Jira, Jira Service Management, and Confluence (Atlassian suite) or comparable work management and ITSM platforms
• Workato or a similar iPaaS platform
• APIs, webhooks, and REST and event-driven integration patterns
• Scripting or programming language for custom automation (Python, JavaScript, Ruby)
• Cloud services for custom middleware, such as AWS (Lambda, API Gateway, EventBridge) or similar

What Sets You Apart?

• You have built governed self-service or citizen development programs where business teams automate safely within guardrails
• You have designed JSM service catalogs, request types, and SLAs that measurably improved response and resolution times
• You have built agents, Projects, Skills, or Gems on Glean, Rovo, Claude, Gemini, or AWS Bedrock for real business use cases, not just experimentation
• You have built audit-ready integrations in an environment subject to SOC 2 or similar compliance requirements
• You have a track record of developing administrators or junior engineers into higher-scope roles
• Relevant certifications such as Atlassian, Workato, AWS, or similar
• Experience in high-growth SaaS or cybersecurity companies
