Job description

• Write Clean, Reusable Code: Consistently follow organized coding practices and established development standards, building reusable components, services, and patterns that others on the team can build on.
• Troubleshoot Independently: Diagnose and resolve technical issues — bugs, plugin conflicts, performance problems, security concerns — with limited need for escalation, and know when a problem does warrant bringing in a Senior Developer.
• Manage Website Maintenance & Support: Independently manage the full range of Website Maintenance & Support (WM&S) requests — from content updates to routine fixes to more technically involved issues — meeting TG’s responsiveness and resolution expectations with minimal oversight.
• Estimate Your Work: Provide accurate, well-reasoned estimates in collaboration with Project Management and Senior Developers, and understand how development decisions affect project scope, budget, and deadlines.
• Own the Outcome: Follow work through to resolution rather than considering a task complete once your portion is done. Communicate what’s needed next and help ensure the intended result.
• Communicate Early: Proactively raise blockers, technical concerns, unexpected complexity, scope changes, or timeline risks before they create downstream problems.
• Collaborate Across Teams: Work closely with Project Management, Accounts, Design, UX, SEO, Content, and Strategy to ensure development work supports the project and client’s larger goals.
• Work With Technical Partners: Communicate directly with hosting providers, client IT teams, and other technology partners to troubleshoot issues and maintain system functionality.
• Improve How We Work: Identify recurring issues, development inefficiencies, documentation gaps, and opportunities to make WM&S and Development processes more effective, and help implement those improvements.
• Grow Into a Stronger Developer: Continue building technical depth through mentorship from Senior Developers, feedback, and hands-on experience, steadily taking on more complex and higher-visibility work.
• Work Flexibly: Work primarily remotely, camera-ready from your dedicated workspace, and meet regularly with clients and internal teams. Collaborate and connect in person, as needed, at our St. Louis HQ.
