Senior Product Engineer

Job Overview

io/ About Semaphore Semaphore is a remote-first software company building continuous integration and delivery (CI/CD) products for engineering teams.

Our customers rely on Semaphore Cloud and our self-hosted enterprise products to build, test, and deliver software securely and reliably. We have spent years building developer infrastructure at scale.

Job Description

We are now using that foundation to create new products and capabilities for a world in which software is increasingly built by people working with AI coding agents.

About the role We are looking for a senior product engineer who can take an important idea from an early, ambiguous problem to a useful product running in production.

You will work across product and engineering boundaries: understanding the user, shaping the solution, making technical decisions, building the system, and improving it based on real use. Some work will extend mature Semaphore products.

Some will start as a small experiment or a new product. In either case, you will be responsible for getting to a strong outcome, not completing a predefined list of tickets. AI coding agents are part of our daily engineering workflow.

You remain accountable for the work: choosing the right problem, setting direction, making trade-offs, reviewing what is produced, and ensuring that the result is coherent, reliable, and maintainable.

This role is for someone with strong ownership, initiative, taste, and judgment. You should be comfortable moving between product questions, system design, code, infrastructure, and user experience as the work requires.

Required Skills and Qualifications
