What We're Looking For

Beyond technical skills, we value engineers who:

• Think operationally. You understand that code running in development != code running in production. You design with operational visibility, rollback safety, and customer confidence in mind.
• Bridge disciplines. You're equally comfortable discussing REST API design and network packet flow; you can translate between engineers and network operators.
• Own outcomes. You follow problems from customer discovery through resolution, taking pride in shipping solutions that solve customer problems.
• Stay current. You invest time understanding emerging network technologies, cloud infrastructure shifts, and how your stack evolves alongside industry trends.
• Communicate clearly. You explain technical decisions in business terms to stakeholders; you write clear documentation and code comments.
