This role provides leadership, hands-on incident response, digital forensics, threat analysis, and coordination support during active incidents. The Lead Incident Responder delivers timely and accurate analysis of internal and external threats using detection and response platforms and collaborates with SOC analysts, threat hunters, IT teams, and management to reduce organizational risk. The scope of the environment includes SIEM, EDR, network security controls, cloud platforms, vulnerability management, and threat intelligence services. Essential Functions * Monitor, investigate, analyze, respond to, and document cybersecurity incidents identified through detection and response platforms. * Serve as Incident Commander, when assigned, to run the bridge, track actions/owners, and drive cadence. * Define severity, business impact, and required engagement level (e.g., Sev1-Sev4), and lead initial triage to determine scope and next actions. * Execute the full incident response lifecycle: identification, containment, eradication, recovery, and post-incident review * Perform in-depth alert and event analysis across SIEM, EDR, network, endpoint, and cloud sources * Collect, preserve, and analyze forensic evidence including logs, disk artifacts, memory artifacts, and network traffic * Apply threat intelligence, indicators of compromise (IOCs), and adversary tactics and techniques using the MITRE ATT&CK framework * Escalate incidents to Cybersecurity Operations Management and Incident Response Team members as required * Support active incident response efforts, tabletop exercises, and threat simulation activities * Conduct investigative analysis to determine impact, scope, and root cause of security incidents * Lead the detection engineering feedback loop by converting incident learnings into new detections/use cases (SIEM rules, EDR analytics), tune to reduce false positives, and validate via testing. * Assist with threat hunting activities to proactively identify malicious activity within the environment * Validate suspected exploitation of vulnerabilities and support remediation efforts * Coordinate with IT, application, and infrastructure teams to support containment and recovery actions * Maintain accurate incident documentation, timelines, and reports * Develop, coordinate, and maintain playbooks for common cyber-related enterprise events including ransomware, business email compromise, identity compromise, etc. * Use (and help improve) SOAR playbooks for containment (account disable, host isolation, IOC blocking), enrichment, and reporting. * Contribute to the development and maintenance of incident response procedures and standard operating procedures (SOPs) * Participate in after-hours and on-call rotation requirements for cybersecurity incidents * Provide regular status updates to Cybersecurity Operations Management during investigations * Coordinate internal/external communications (Legal, Privacy, Comms/PR, HR) following established playbooks. * Coordinate with MSSP/IR retainer and key vendors as needed during active incidents * Track and report MTTA/MTTR, dwell time, containment time, recurrence, and lessons learned; contribute to operational reporting. ## Related Videos - [Our journey with Spring Boot in a microservice architecture](https://www.wearedevelopers.com/videos/511-our-journey-with-spring-boot-in-a-microservice-architecture) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [What Developers Get Wrong About Application Quality](https://www.wearedevelopers.com/videos/233-what-developers-get-wrong-about-application-quality) - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Checkmate: 5 Real Incidents That Can End a Software Company](https://www.wearedevelopers.com/videos/100126-checkmate-5-real-incidents-that-can-end-a-software-company) ## Related Articles - [9 Ways to Make Money Hacking](https://www.wearedevelopers.com/magazine/333-9-ways-to-make-money-hacking) - [Dev Digest 134 - Where pixels sing?](https://www.wearedevelopers.com/magazine/477-dev-digest-134-where-pixels-sing) - [Walking Into The Era of Supply Chain Risks](https://www.wearedevelopers.com/magazine/106-walking-into-the-era-of-supply-chain-risks) - [Events like RSAC Get You CISOs.
