We are seeking a Senior Cloud Software Engineer to join our Threat Detection and Incident Response (TDIR) team, building world‑class case management and investigation capabilities in Go on our AI‑native Falcon Next‑Gen SIEM platform. Your work will help customers detect, investigate, and hunt threats faster and more intelligently at petabyte scale.

What You’ll Do

• Own the engineering bar: drive architectural improvements, set code quality standards, and ensure our systems are performant, reliable, and scalable.
• Lead system design and architecture decisions, including design reviews and RFC processes.
• Develop Go‑based microservices supporting threat detection, case management, and incident response workflows, alongside RESTful APIs powering customer‑facing capabilities.
• Take end‑to‑end ownership of technical initiatives, both individually and as part of a team, across projects of increasing scope and complexity.
• Collaborate with designers, product managers, and engineers across product groups to understand, design, and implement solutions.
• Mentor junior and mid‑level engineers through pair programming, code reviews, and one‑on‑one knowledge sharing.
• Contribute to AI‑powered capabilities including LLM integration, agentic workflows, and intelligent analyst tooling.
• Participate in the on‑call rotation and drive improvements that reduce toil and increase system reliability.
• Operate with a high degree of autonomy—making decisions and driving outcomes.

What You’ll Need

• 8+ years of professional software engineering experience, with 5+ years building and operating distributed systems or cloud‑native services at scale in production.
• Solid understanding of distributed systems, scalability, RESTful patterns, and multithreading concepts.
• Proficiency building and scaling resilient, low‑latency services using Go, Python, Java, C++, or C#.
• Hands‑on experience with Docker, Kubernetes, and cloud platforms, preferably AWS or GCP.
• Strong communication and collaboration skills, with a bias for ownership and a customer‑first mindset.
• Proven ability to translate complex and ambiguous business requirements into technical solutions and deliver projects on schedule.
• Bonus: Current experience developing Go‑based microservices for scalable, high‑throughput architectures.
• Bonus: Experience in cybersecurity, SIEM, SOAR, or adjacent security domains.
• Bonus: Hands‑on experience with LLM integration, prompt engineering, RAG pipelines, or agentic AI frameworks.
