Through continuous innovation and a growth mindset, we build cutting-edge security solutions that help customers stay ahead of emerging challenges.\nMicrosoft Security is launching Project Compass, a new product group that addresses one of the most critical emerging challenges in cybersecurity: securing cryptographic infrastructure in the AI and quantum era. Driven by evolving threats, growing customer demand, and increasing regulatory requirements, organizations must gain visibility, control, and protection over their cryptographic assets while preparing for a quantum-safe future.\nThe Compass engineering team will build the next generation of cryptographic security solutions, from continuous discovery and risk assessment to AI-driven remediation and post-quantum readiness. Working closely with engineers, security researchers, and product teams across Microsoft, we bring together expertise in cybersecurity, AI, cryptography, and cloud-scale engineering. This is a unique opportunity to build a new product from the ground up and deliver solutions with global impact.\nWe are currently hiring for multiple Software Engineering positions across our team in Israel. By applying to this unified pipeline, you will be considered for a high-impact role (at either the Senior Software Engineer or Principal Software Engineer role)\nMicrosoft's mission is to empower every person and every organization on the planet to achieve more. As employees, we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day, we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.\nIn alignment with our Microsoft values, we are committed to cultivating an inclusive work environment for all employees to positively impact our culture every day.\nResponsibilities\nAs a Senior/Principal Software Engineer in the Compass group, you will design, build, and deliver cloud-scale capabilities for cryptographic asset discovery, risk assessment, and remediation. You will use LLMs and autonomous agents to automate and enhance how organizations manage and address cryptographic risk. This role involves building practical, production-grade security capabilities that help customers secure their cryptography and become quantum-safe.\nDesign, implement, and support cloud-scale services for cryptographic asset discovery, risk assessment, posture management and remediation capabilities.\n\nBuild AI-driven and agentic capabilities that identify, prioritize, and remediate cryptographic risks and speed up post-quantum readiness.\n\nCollaborate with engineers, security researchers, product managers, and cross-functional teams across Microsoft to deliver high-quality features, drive innovation, and meet project goals.\n\nContinuously learn and apply new technologies to improve our services.\n\nContribute to the team's engineering practices and culture as an early member of a new group.\n\nQualifications\nWe are hiring for multiple roles in Project Compass, a new product group in the Security GCR organization, across both Senior Software Engineer and Principal Software Engineer levels.\nYou have at least 7+ years of hands-on software engineering experience building production systems in languages such as C#, Java, Rust, Go, or Python.\nProven experience designing, building, and operating complex, scalable, reliable, and secure distributed cloud services.\nStrong system design skills for high-scale systems, including architecture, performance, resiliency, observability, and maintainability.\nExperience owning features/services/products end-to-end: design, implementation, testing, deployment, integrations and operations.\nPreferred Qualifications\nB.Sc., M.Sc., or Ph.D. in Computer Science, Software Engineering, or a related technical field (or equivalent practical experience).\nExperience building and shipping AI/LLM or agentic capabilities in production or advanced prototypes, including prompt/workflow design, evaluation, and integration.\nKnowledge of security systems and cybersecurity fundamentals.\nExtensive knowledge and hands-on experience with cryptographic infrastructures and the following: PKI, keys, certificates, Identity and digital signatures, cryptographic protocols and libraries.\nExperience building cybersecurity products, cloud security platforms, or large-scale security data platforms (such as ingestion pipelines, connectors, and graph-based models).\nDemonstrated ability to drive ambiguous 0-to-1 problems into clear architecture and executable milestones.\nStrong cross-functional collaboration with engineering, security research, and product teams.\nExperience in early-stage or startup-like product incubation environments.\nFamiliarity with compliance frameworks and security standards (for example: NIST, FIPS, PCI, and sector-specific regulations).\nThis position will be open for a minimum of 5 days, with applications accepted on an ongoing basis until the position is filled.\nMicrosoft is an equal opportunity employer.
