What are we looking for?

We are looking for a Threat Intelligence Reseacher to join our Threat intelligence and response team and help improve our clients’ security posture and cyber resilience.

This is a hands-on specialist role focused on threat research, intelligence production, and translating complex threat activity into practical guidance. You will investigate threat actors, campaigns, intrusion techniques, malware, and significant cyber events, turning your findings into intelligence that customers and our internal teams can act on.

You will work directly with customers, presenting threat assessments and helping them understand how changes in the threat landscape relate to their industry, technology, and exposure. You will also develop and deliver internal training, strengthen our threat-intelligence capabilities, and share your expertise across the organization.

This is primarily a content and subject-matter-expert role. Customer communication is an important part of delivering that expertise, while account ownership and commercial relationship management remain with the relevant Customer Success and commercial teams.

What You’ll Do

Research threat actors, campaigns, malware, adversary infrastructure, vulnerabilities, intrusion techniques, and significant cyber events.

Produce sector threat landscapes, campaign assessments, threat-actor profiles, flash advisories, executive briefings, and technical intelligence reports.

Combine intelligence from open sources, incident-response investigations, MDR observations, security telemetry, and other relevant sources.

Assess which threats are genuinely relevant to customers based on their industry, geography, technology, and known exposure.

Translate technical findings into clear and actionable recommendations for security teams, CISOs, business leaders, and executive audiences.

Map adversary activity to MITRE ATT&CK techniques, attack paths, indicators of compromise, and detection opportunities.

Support threat-led detection engineering by identifying emerging techniques, telemetry requirements, detection gaps, and opportunities for proactive threat hunting.

Work closely with Incident Response, MDR, Exposure Management, Detection Engineering, and Consulting specialists.

Deliver customer briefings, workshops, and threat-intelligence sessions.

Design and deliver internal training for consultants, analysts, Customer Success teams, and other relevant stakeholders.

Maintain reusable intelligence content, research methodologies, and recommendation libraries.

Peer-review intelligence products and help maintain a consistently high analytical standard.

Contribute to blog posts, research publications, webinars, and other thought-leadership activities.

How the Role Can Develop

We want this role to provide a genuine path towards deeper and more visible threat research.

As you demonstrate strong analytical quality, initiative, and customer impact, you can take increasing ownership of:

Conducting original research into threat actors, campaigns, malware, and emerging attacker techniques.

Analyzing our exposure management service

Longer-term threat-research projects based on observations from our customer environments, MDR operations, and incident-response engagements.

Authoring detailed threat-intelligence reports and public research publications.

Developing new research methods and shaping the direction of our threat-intelligence capability.

Representing WithSecure through webinars, industry events, media briefings, and cyber security conferences.

Mentoring other analysts and helping develop the next generation of threat-intelligence specialists.

Conference presentations and public research would not be separate from the role—they would be a natural extension of high-quality work produced within it.

What We’re Expecting From You

At least three years of relevant professional experience in threat intelligence, threat research, incident response, malware analysis, threat hunting, detection engineering, SOC, or MDR environments.

Demonstrated experience investigating threat actors, campaigns, intrusion activity, or significant cyber events.

The ability to produce well-supported intelligence assessments rather than simply aggregate or summarize threat news.

A solid understanding of attacker tradecraft, intrusion lifecycles, common malware capabilities, command-and-control infrastructure, and adversary techniques.

Experience evaluating source reliability, distinguishing established facts from analytical judgments, and communicating confidence levels and intelligence gaps.

The ability to connect threat intelligence with customer-specific risk, exposure, and defensive priorities.

Strong analytical writing skills and the ability to produce clear, concise, and defensible reports.

Confidence presenting complex technical subjects to technical specialists, business leaders, and executive audiences.

The interpersonal skills to work directly with customers as a trusted subject-matter expert.

The ability and motivation to create training material, facilitate internal sessions, and mentor colleagues.

Intellectual curiosity and the persistence required to investigate incomplete or conflicting information.

Proficiency in English.

The ability to work independently while actively collaborating and sharing knowledge with others.

Being an awesome colleague!

Bonus Points For

Experience working with EDR, SIEM, MDR, threat-intelligence platforms, or large-scale security telemetry.

Practical experience in incident investigation, threat hunting, or detection development.

Experience with malware analysis, adversary infrastructure tracking, or advanced open-source intelligence techniques.

Familiarity with analytical frameworks such as MITRE ATT&CK, the Diamond Model, the Cyber Kill Chain, or structured analytical techniques.

Knowledge of cloud, identity, SaaS, and hybrid-environment threats.

Experience producing intelligence for industries such as finance, manufacturing, healthcare, energy, or the public sector.

Scripting or query-language skills that support research and analysis.

Previous experience publishing security research, writing technical reports, speaking at events, or contributing to the cyber security community.

Relevant certifications such as GCTI, GCFA, GREM, CISSP, or equivalent practical expertise.

Understanding of how threat intelligence supports NIS2, DORA, executive decision-making, and broader cyber-risk management.
