Senior Full-Stack Engineer & Tech Lead (AI-Driven)

Zivtech, Llc; Philadelphia (Philadelphia County); On-site; USD 120,000 - 160,000; Full time

Job summary

Zivtech is seeking a Senior Software Engineer (Full Stack) to own projects end-to-end — from early discovery and estimation through delivery and iteration, with technical leadership, client interaction, and project ownership at the core. You’ll work directly with clients, project managers, designers, and other engineers.

You’re expected to lead projects, delegate effectively, make strong technical calls, and communicate clearly when things are on track — and when they aren’t.

Qualifications

• 5+ years building and shipping production web applications.
• Lead projects and own outcomes.
• Experience with React or another modern JavaScript framework.
• Solid PHP experience, including OOP and design patterns.
• Deep experience with Drupal (8/9/10) — custom modules, theming, site building.
• Experience with Drupal migrations.
• Strong Git fundamentals and modern development workflows.
• Experience integrating with external APIs and third-party systems.
• Comfort with SQL and database-backed applications.
• Command-line fluency and tools like Drush.
• Strong communication and listening skills — especially client-facing.
• Good judgment, attention to detail, and the ability to work independently.
• Strong attention to detail — applicants should include the phrase “Greetings Zivtech Crew” somewhere in their cover letter or application materials

Responsibilities

• Own projects from start to finish — requirements, architecture, implementation, delivery, and post-launch support
• Serve as a technical lead and primary engineering contact for clients
• Communicate clearly with clients and internal teams, translating business needs into technical decisions
• Break down complex work and delegate effectively to other engineers
• Use AI agents and AI-assisted workflows to increase leverage and delivery velocity
• Support sales, architects, and leadership with discovery, estimates, and technical direction
• Work on the critical path to ensure projects ship on time and within scope
• Write high-quality front-end and back-end code
• Perform code reviews and help set engineering standards
• Mentor other engineers through feedback, pairing, and review
• Identify technical and delivery risks early — and surface them clearly
• Partner with project managers to manage scope, timelines, and budgets
