Summary
👤
Senior🎓
Top SchoolJoel Turnbull is a Staff Software Engineer and pragmatic technology leader based in Cincinnati with roughly two decades of experience designing, building, and shipping maintainable web and service-oriented systems. He has progressed from hands-on engineering to founding and leading teams—most recently as Head of Engineering and now Staff Engineer at Topstep—bringing a blend of architecture, delivery ownership, and servant leadership. Joel excels at turning messy product and operational requirements into auditable, scalable solutions, having introduced event-driven billing, AI-driven query surfaces, and ecommerce integrations that handled hundreds of thousands of orders. He pairs technical mentorship and hiring acumen with disciplined engineering practices (TDD/BDD, staged rollouts, code conventions) to reduce technical debt and accelerate teams. Not obvious from titles alone, he’s repeatedly acted as the bridge between customers, product, and engineers—running discovery, story mapping, and client-facing engagement to prioritize customer value. Educated in business, computer science, and design, he blends product-minded engineering with clear communication to deliver measurable outcomes.
