Role 

We are looking for a Senior Staff Software Engineer to join our Customer/Cloud Reliability SW Engineering team. This is a hybrid role reporting to the Senior Director, SW Engineering, within the Software Engineering department. You will drive the technical evolution of our cloud reliability platforms, designing distributed software that enables autonomous detection and remediation of issues at enterprise scale. By leveraging agentic AI frameworks and deep systems expertise, you will reduce mitigation times and build the foundational tools that ensure our cloud services remain secure and highly available.

What you’ll do (Role Expectations)

• Design and develop end-to-end distributed software and platforms that enable automatic detection, diagnosis, and safe remediation of issues in a large-scale cloud
• Drive the team technically towards problem solving and build platforms/apps that improve security, reliability, observability, and diagnosability at enterprise scale
• Design and build production-grade AI Agents leveraging LLMs and agentic frameworks to accelerate incident triage, guided diagnostics, RCA, and runbook execution
• Develop cloud reliability, observability, and supportability services for a large-scale cloud spanning Linux/BSD, bare metal, and Kubernetes
• Perform deep troubleshooting across OS, networking, and distributed systems including performance analysis, packet captures, and core dumps where applicable

Who You Are (Success Profile)

• You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.
• You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. True ownership involves leveraging dynamic range: the ability to navigate seamlessly between high-level strategy and hands-on execution.
• You are a problem-solver. You love running towards the challenges because you are laser-focused on finding the solution, knowing that solving the hard problems delivers the biggest impact.
• You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving ongoing feedback—knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust.
• You are a learner. You have a true growth mindset and are obsessed with your own development, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose.

What We’re Looking for (Minimum Qualifications)

• 5+ years of experience in Software Development or related engineering teams
• Proficiency in programming languages such as Python, C, or C++ and experience with Linux environments
• Hands-on experience with network security products and technical knowledge of technologies like Proxy, Firewall, VPN, and Data protection
• Proven experience developing automation for troubleshooting and monitoring purposes
• Demonstrated ability to provide technical leadership and vision for cloud and customer reliability tools, with leadership experience being a plus

What Will Make You Stand Out (Preferred Qualifications)

• Bachelor’s Degree in Computer Science or a relevant Engineering field
• Experience in full stack application development and utilizing Agentic AI frameworks like AutoGen, CrewAI, Langchain, or Langraph
• A track record of delivering products as cloud-based security services
