Responsibilities

We are seeking an experienced Engineer (Cybersecurity Analytics & Automation) who combines strong software engineering skills with a hands-on analytical mindset. This role will focus on identifying and investigating automated and malicious activity targeting internet-facing applications and APIs , including bot attacks, account takeover attempts, fraud patterns, API abuse, and other anomalous behavior.

The ideal candidate will have a strong understanding of Layer 7 (HTTP/HTTPS) traffic and application security , along with the ability to analyze large-scale security and application datasets using Python, Elasticsearch, REST APIs, and related data-processing technologies .

This is a hands-on engineering and analytics role. The engineer will perform detailed manual investigations to understand emerging attack patterns and then translate repeatable analytical processes into scalable queries, detection logic, and Python-based automation .

The role also requires practical experience with Generative AI tools and AI-assisted engineering , including ChatGPT and GitHub Copilot, to accelerate investigation, data analysis, automation development, and operational efficiency.

Key Responsibilities:

• Investigate suspicious and malicious activity targeting internet-facing applications, websites, and APIs, with particular focus on automated bot activity and Layer 7 attacks .

• Perform hands-on analysis to identify malicious bots, credential stuffing, account takeover attempts, scraping, fraud patterns, API abuse, application-layer attacks, and anomalous network/application behavior .

• Analyze large-scale and diverse datasets, including:

• Application logs
• Web Application Firewall (WAF) events
• Bot management and bot detection signals
• API and network telemetry
• Authentication and account activity
• Fraud and security events
• Threat intelligence feeds and external data sources

• Develop and optimize Elasticsearch queries to investigate security events, correlate signals, identify behavioral patterns, and support detection use cases.

• Use Python and REST APIs to collect, enrich, correlate, process, and analyze security data from multiple systems.

• Identify repetitive manual investigation and analysis activities and convert them into reusable, scalable automation .

• Correlate signals across WAF, bot management, application, authentication, fraud, and threat intelligence platforms to distinguish legitimate users and automation from malicious activity.

• Work with large-scale datasets and distributed data-processing environments to identify trends and attack patterns that may not be visible from individual events.

• Evaluate and apply Generative AI to security analytics and engineering workflows, including investigation assistance, query generation, data analysis, code development, and automation.

• Effectively use AI-assisted engineering tools such as GitHub Copilot and ChatGPT to accelerate development while applying appropriate validation and secure engineering practices.

• Document investigation methodologies, detection logic, automation workflows, and operational procedures.

• Collaborate with cybersecurity, application engineering, fraud, infrastructure, and data teams to improve detection capabilities and strengthen protection of internet-facing services.

Qualifications

Minimum Qualifications :

• Bachelor's degree in Computer Science, Cybersecurity, Engineering, Data Science , or a related technical field.

• 5+ years of software engineering, security engineering, security analytics, or related technical experience .

• Strong programming and automation skills using Python .

• Strong experience working with REST APIs and structured/semi-structured data.

• Hands-on experience with Elasticsearch , including querying and analyzing large datasets.

• Strong understanding of HTTP/HTTPS, REST APIs, Layer 7 protocols, web applications, and internet-facing application architectures .

• Ability to independently perform detailed investigations, formulate hypotheses, analyze data, and distinguish legitimate activity from suspicious or malicious behavior.

• Demonstrated ability to convert manual analytical processes into Python-based automation and repeatable engineering solutions .

• Practical experience using Generative AI and AI-assisted development tools , including ChatGPT, GitHub Copilot, or comparable technologies.

• Familiarity with modern software engineering practices, including Git, CI/CD, testing, code reviews, and secure development practices .

• Strong analytical, problem-solving, and communication skills.

Preferred Qualifications :

• Experience working on Docker, Kubernetes and Kafka.

• Experience analyzing large-scale application logs, security telemetry, network data, API traffic, or cybersecurity datasets .

• Working knowledge of cybersecurity concepts related to bots, application security, API security, fraud, account takeover, and automated attacks .

• Experience with cloud security platforms such as Cloudflare, Akamai WAF/Bot manager , or comparable technologies.

• Experience with SIEM, security analytics, observability, or threat detection platforms .
