About the role

Key responsibilities & impact

Identify and solve high-complexity engineering problems with the potential for outsized improvements in speed, efficiency, cost, or developer effectiveness
Build and apply technical solutions that optimize compute-heavy and workflow-heavy parts of the software-development process
Analyze systems and behavioral patterns across teams and codebases to find root causes of waste, friction, duplication, or poor performance
Implement scalable improvements that can be applied broadly rather than solving the same problem repeatedly in isolated ways
Partner with teams to improve both technical systems and the engineering practices that surround them
Teach and enable engineers so that better patterns are understood, adopted, and sustained over time

Requirements

What you’ll need

10+ years of professional software engineering experience
Demonstrated ability to solve unusually difficult technical problems with limited oversight and high ambiguity
Strong track record of delivering high-leverage technical improvements across software, automation, platforms, or engineering workflows
Excellent systems thinking and analytical skills, with the ability to find non-obvious sources of inefficiency and address root causes at scale
Deep hands-on engineering capability, including the ability to move from investigation to implementation in complex environments
Passion for correctness, usability, efficiency, and creating systems that make good engineering outcomes easier to achieve.
