• Proven experience with unit testing, integration testing, and deploying services in Kubernetes or a similar container orchestration platform.
• Demonstrated ability to design, build, and operate fault-tolerant systems.
• Strong communication skills to present and articulate designs to technical and non-technical audiences.
• Understanding of offensive security methods and tactics.
• Knowledge of networking concepts including DNS, TCP/IP, routing protocols.

Requirements

• You feel comfortable leading, motivating, and delegating team initiatives.

• You are comfortable with ambiguity, fast-paced delivery, and pivoting when priorities change.
• You are driven off of goals and team outcomes.
• You are focused on the iterative delivery of high-quality well tested code.
• You are conscious of scalability, re-usability, but also realistic when it comes to trade-offs.
