APPLICATION SUPPORT DEVELOPER JOB DESCRIPTION

Enterprise applications don't fix themselves. When production environments degrade, release scripts fail audit review, or end-user workflows stall, the work halts for everyone depending on those systems. Application Support Developers prevent and resolve exactly these failures - owning the layer where software development meets operational continuity. This role spans both the SCRUM sprint cycle and the on-call rotation, demanding equal comfort with writing stored procedures and explaining root cause to non-technical stakeholders. Agile delivery norms and object-oriented design standards govern daily output.

As the Application Support Developer, you maintain, enhance, and stabilize enterprise web applications and internal business systems, keeping mission-critical workflows operational while contributing to new feature delivery within cross-functional squads. You collaborate directly with infrastructure, QA, and business operations teams, with scope typically spanning multiple application platforms and technology stacks under guidance from a product or IT leadership stakeholder.

Career Impact: Deep exposure to the full software development and release cycle, including BRD authorship, test case design, and production monitoring, builds the cross-functional credibility that mid-career developers need to move into lead or architect roles.

Business Impact: The enterprise applications you support drive payroll processing, order fulfillment, and customer-facing operations, meaning unresolved incidents translate directly into stalled business processes and user downtime.

Growth Opportunity: Working across object-oriented development, cloud-based platforms, and DevOps tooling in a single role sharpens a skill profile that commands senior individual contributor or engineering lead opportunities within two to three years.

• Investigate, diagnose, and resolve production incidents spanning in-house and vendor-developed enterprise applications to restore service within agreed timelines.
• Develop and maintain server-side and client-side application components, including stored procedures and complex SQL queries, to support evolving business requirements.
• Design and execute test plans, including test environment configuration and back-end validation, to verify changes before go-live releases.
• Implement and release approved code changes and scripts, ensuring each deployment meets audit and change-management requirements.
• Collaborate with infrastructure, database, and networking teams to drive application performance tuning and architectural stability improvements.
• Automate repetitive IT processes and batch workflows to reduce manual intervention and improve overnight operational reliability.
• Document solution design, root-cause findings, and user requirements clearly enough for both technical and non-technical audiences.
• Support cloud-based application configuration and customization, including integration setup and patch coordination with end users.

• Bachelor's degree in Computer Science, Information Systems, Engineering, or equivalent work experience.
• 2 or more years of application support or software development experience, with demonstrated involvement in production environment troubleshooting.

• Effective written and verbal communication skills, with demonstrated ability to convey technical findings to non-technical stakeholders.
• Strong analytical and problem-solving skills, with the capacity to manage multiple concurrent incidents under time pressure.

• Experience supporting or developing workflows within ERP, HCM, or Payroll systems used by business operations teams.
• Familiarity with containerization or virtualization platforms, reflecting comfort with modern deployment environments.
• Exposure to Agile or SCRUM delivery frameworks, including sprint planning, backlog grooming, and story authorship.
• Understanding of application security principles and access-management auditing requirements within enterprise IT governance.

• Incident mean time to resolution, measuring how quickly production issues are identified and closed.
• Release deployment success rate, reflecting how often code changes reach production without rollback.
• Test environment defect escape rate, tracking defects that slip through pre-release validation into production.
• Automation coverage of recurring batch and IT processes, measured as percentage of manual tasks eliminated per quarter.
• Documentation currency rate, reflecting the proportion of runbooks and solution records updated within defined review cycles.
• Typical tools: version control (commonly Git); issue tracking (commonly JIRA or ServiceNow); database querying (commonly SQL Server or Oracle).

• Base Salary Range: $70,000 to $100,000 annually, depending on experience and location
• Bonus: Annual performance bonus, typically 5% to 10% of base salary
• Equity: Stock options or RSUs offered at some employers, particularly in growth-stage software companies
• Health Benefits: Medical, dental, and vision coverage; employer contribution varies by company
• PTO: 15 to 20 days annually, plus standard US public holidays
• Common Perks: Remote or hybrid flexibility, continuing education reimbursement, on-call stipends where applicable
