The Role

Black Lotus Labs has an opening for a lead security engineer that will leverage Lumen’s unique visibility to hunt botnets and scale discovery of evolving malicious threats in the criminal ecosystem. Our distinctive data sets as well as our computing cluster present exciting opportunities to integrate machine learning outputs and graph analytic techniques as we find new ways to hunt threats across the internet. Black Lotus Labs has detected and disrupted key evolving threats at an internet scale for years.

This position will work alongside other advanced security researchers, data scientists, data engineers, and malware reverse engineers to tackle evolving threats accelerated by technologies like our Hadoop ecosystem (HBase, HDFS, Spark, Kafka, AirFlow), Elasticsearch and Redis clusters, Docker using Docker Swarm, malware environment, and a network of honeypots.

This is a close-knit, experienced, amazingly smart team that you can be a part of and help build out. This is a remote/work-from-home opening as well available anyw in the US with travel around 2 times per year.

The Main Responsibilities

  • Research latest threat attacker tools, techniques and procedures (TTPs) with a goal of automating detection
  • Regularly prepare findings for technical internal and external publications.
  • Analyze attacks and use forensic data and OSINT methods for investigation
  • Apply strong knowledge of systems architecture and security as well as deep network and application protocol knowledge to analyze attacks and threat actor methodologies
  • Automate investigations through Python scripting
  • Set priority of what threats to analyze and how long to spend on them to maximize the team's impact
  • Work with team to scale analysis of evolving threats and tracking threat actors in collaboration with data scientists to leverage machine learning and graph analytic outputs
  • Build and maintain trust relationships with other intelligence teams, law enforcement, and other outside groups
  • Support threat research customer and partner RFIs
  • Work as the team point-of-contact in a rotational cycle to triage incoming research-related events
  • Contribute to deliverables and performance metrics w applicable
  • Act as company SME for threat actor-related issues
