We’re looking to diversify our team with people who are humble, creative, and eager to learn. We are a remote friendly, global team, but provide the option of working in-office in New York City, Sioux Falls, Porto, Lisbon, and Singapore. For our colleagues not located near our beautiful offices, we encourage and sponsor quarterly in-person collaboration days to work together and further deepen our Village The Security Operations team develops hardware and software solutions designed to establish and test security guardrails across the code, cloud resources, and hardware infrastructure of the Anchorage platform. By managing vulnerabilities in both in-house and third-party components, the team partners with service owners to secure networking and infrastructure while continuously monitoring for anomalies or unexpected configuration changes. To enhance efficiency, they strategically automate investigation tasks, threat isolation, inventory management, and assurance provision for regulated entities, all while conducting rigorous static and dynamic testing of application interfaces throughout the organization. We have created the Factors of Growth & Impact to help Villagers better measure impact and articulate coaching, feedback, and the rich and rewarding learning that happens while exploring, developing, and mastering the capabilities and contributions within and outside of the Security Operations position.
