• Own technical areas across the PowerPoint for the web stack, including front-end experiences, client architecture, and integration with AI and agent services, and contribute to technical direction for the engineers working in those areas.
• Lead technical designs and evaluate architectural trade-offs related to performance, scalability, reliability, maintainability, security, privacy, AI safety, and cost.
• Apply secure-by-design engineering practices, including threat modeling, secure coding, dependency management, security testing, and appropriate mitigations for AI-specific risks such as prompt injection, data exfiltration, and unsafe agent actions.
• Define and drive quality strategies for owned features, including automated testing, AI evaluation, telemetry, monitoring, performance measurement, and appropriate success and guardrail metrics.
• Drive safe deployment and production readiness for owned areas using deployment automation, feature flags, staged rollouts, monitoring, validation, and rollback mechanisms.
• Act as a Designated Responsible Individual (DRI) for owned areas and help drive incident response, mitigation, root-cause analysis, and follow-up improvements that strengthen service reliability and prevent recurrence.
• Work closely with Product Management, Design, Research, Applied Science, Security, and Privacy partners to translate ambiguous customer needs and emerging AI technologies into product direction and actionable technical plans.
• Use AI-assisted development tools and practices throughout the software development lifecycle while reviewing, validating, and taking responsibility for AI-generated code, designs, tests, and other engineering artifacts.
• Drive alignment with partner teams on dependencies, shared components, APIs, architecture, security requirements, and engineering patterns needed to deliver end-to-end customer experiences.
• Identify opportunities to improve performance, reliability, maintainability, security, developer productivity, and engineering efficiency within owned areas.
• Review technical designs and code, provide actionable technical feedback, and mentor engineers to improve engineering quality, security, reliability, and technical decision-making.

• Bachelor's Degree in Computer Science or related technical field AND 4+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience.

• Master's Degree in Computer Science or related technical field AND 6+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript/TypeScript, or Python OR Bachelor's Degree in Computer Science or related technical field AND 8+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript/TypeScript, or Python OR equivalent experience.

• Experience designing and delivering complex web applications, client architectures, or large-scale production services.
• Experience developing AI or LLM-powered product experiences, including integration with language models, multimodal models, agents, tool use/function calling, or related AI technologies.
• Experience with AI security and safety practices, such as threat modeling, prompt-injection defenses, data protection, agent security, or evaluation and guardrail systems.
• Experience defining testing, evaluation, telemetry, and quality strategies for AI-powered features or production software.
• Experience evaluating performance, scalability, reliability, security, and architectural trade-offs in complex production systems.
• Experience leading technical designs across multiple components, driving cross-team technical alignment, and delivering features from design through production.
• Experience mentoring engineers and contributing to improvements in engineering quality, security, reliability, or development practices.
• Effective communication skills and experience collaborating across Engineering, Product Management, Design, Applied Science, Research, Security, and Privacy teams.
