Krystian Cybulski

I am an engineer at heart and love to build things. I started building software over 20 years ago, and went on to build teams and eventually whole engineering departments. Working with American firms in finance, HR, and education, I've helped distributed, remote, and hybrid teams achieve success through effective strategies and good execution.

Building great products requires a harmony of art, science, and intuition. You need to execute now, and get a good product out the door. You also need to consider the future, and see how you will nurture and care for the things that you have built. Finally, you need to be able to react to new realities and the unexpected. I can help you by drawing on my experience—I’ve done this before.

15Five Inc.

San Francisco, CA - remote

My decade-long tenure at 15Five started as "employee #1" and ended with leading the engineering department. During this time, 15Five grew from 1 to 300+ people, raised multiple funding rounds, defined a new market category, and became one of the leading players in the employee performance management space. I've built a large portion of the initial product, shaped the technical direction by making, and later overseeing, strategic technical decisions.

In the department leadership role, working alongside the CTO, led the engineering team of over 50 people. Was responsible for development, DevOps, and QA teams, and focused on allowing them to work well together. Implemented, oversaw, and managed the system and people performance metrics, and used them to regularly draw insights and support strategic decisions. Participated in the due diligence for the acquisition of an employee engagement company, and led the integration of the technical platforms. Working with the senior leadership team, made sure the engineering department's goals aligned with and supported the wider and longer-term company strategy.
