We are looking for a Senior Product Engineer to own features end-to-end—from problem discovery and system design to implementation, deployment, and continuous improvement. You will work autonomously across the stack, making pragmatic engineering decisions that deliver meaningful customer value. At countX, you won’t be handed a backlog of predefined tickets; instead, you’ll be trusted to identify opportunities, define solutions, and bring them to life.
Our engineering team embraces modern AI-assisted development practices and works extensively with Claude Code to accelerate development and improve code quality. Our tech stack includes PHP, TypeScript, Python, Go, and React, and we value engineers who are comfortable working across technologies and choosing the right tool for the problem at hand.
Your Responsibilities
- Own product features end to end — from discovery and design through delivery, monitoring, and iteration
- Make sound system design and architecture decisions, balancing speed, scalability, and maintainability
- Think infrastructurally — understand how your code runs, scales, and fails in production, and design accordingly
- Work autonomously with minimal supervision, setting your own direction and managing your own priorities
- Use Claude Code and modern AI-assisted development workflows to deliver high-quality software faster
- Collaborate with product, design, and other engineers to turn ambiguous problems into shipped solutions
- Raise the engineering bar through pragmatic decisions, clean implementation, and continuous improvement
