About the role

Responsibilities:
- We are looking for a Staff Detection Engineer to join our team.
- This is a Hybrid (Pune, India) role, reporting to the Senior Manager in the Threat Hunting department.
- You will combine threat research and engineering expertise to build the next generation of detections across AWS and cloud infrastructures.
- By leveraging big data platforms like Hadoop and Athena, you will design scalable hunting logic and automated pipelines to defend our global footprint and enhance threat visibility.
- Combine threat research and engineering expertise to develop advanced detections and hunting logic using Python and AWS infrastructure
- Design, scale, and maintain engineering projects, including GitLab pipelines and repeatable deployment steps to improve hunting efficiency
- Develop YAML-based detections and SIGMA-like rule technologies while migrating existing hunting detections to next-generation systems
- Utilize data platforms like Hadoop, Athena, and data lakes to monitor and test new intelligence sources for enhanced threat visibility
- Independently write detections and playbooks while supporting operational demands, including weekend night shifts and on-call rotations
Qualifications:
- Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain
- Proven experience in detection engineering, threat hunting, security operations, or malware analysis
- Hands-on experience developing and implementing detection rules in SIEM tools such as Splunk, Microsoft Sentinel, or ElasticSearch
- Deep familiarity with the MITRE ATT&CK framework and experience translating TTPs into actionable detection logic
- Bachelor’s or graduate degree in Computer Science, Engineering, or a related discipline, or equivalent security industry experience, combined with the ability to work flexible schedules, including weekend night shifts, to meet global operational demands
- Experience leveraging AI/ML models, large language models (LLMs), or natural language processing (NLP) to automate threat intelligence synthesis, accelerate detection rule generation, or build predictive anomaly detection models within big data systems
- Significant experience as a Senior Detection Engineer leading complex detection strategies and mentoring junior team members
- Expertise in validating detection logic, performing root cause analysis of failures, and delivering platform improvement recommendations, paired with advanced scripting and automation skills in Python for developing and managing complex detection infrastructure
