Security Researcher

What you'll do :

- The primary tasks of this position relate to the detection, triage, and analysis of malicious open source software components - identifying threats across public package ecosystems (npm, PyPI, Maven, etc.) and assessing their scope, intent, and impact.

- Day-to-day work includes triaging and assessing incoming malware alerts, reviewing Indicators of Compromise (IoCs), and maintaining threat campaign records to track attacker infrastructure, tactics, and patterns over time.

- A core responsibility is the in-depth technical analysis of suspicious packages: reverse-engineering obfuscated code, identifying malicious behaviors (exfiltration, backdoors, dependency confusion, typosquatting, etc.), and producing detailed internal assessments.

- You will author and publish external-facing content - blog posts, technical write-ups, and security advisories - communicating findings clearly to both technical and non-technical audiences, and contributing to the broader security community's awareness of emerging threats.

- You will collaborate with internal teams to feed findings into detection pipelines, enrich our vulnerability and threat database, and help improve automated detection coverage over time.

What we're looking for :

- Bachelor's degree in engineering or a related field, with at least 3 years of hands-on professional experience specifically in malware analysis, threat intelligence, or open source package security.

- Demonstrated experience triaging security alerts at scale and working within or alongside a SOC or threat intelligence team.

- Hands-on experience reviewing and interpreting IoCs (file hashes, domains, IPs, behavioral signatures) and maintaining threat campaign tracking.

- Proficiency in reading and analyzing code across multiple languages (Python, JavaScript/TypeScript, Java, Go) - including obfuscated or minified code.

- Experience producing external security communications: blog posts, advisories, or technical reports intended for a public or customer-facing audience.

- Understanding of package manager ecosystems and common attack patterns (typosquatting, dependency confusion, malicious install scripts, etc.).

Nice to have :

- Experience contributing to or operating threat intelligence platforms or malware databases.

- Familiarity with static and dynamic analysis tooling (sandboxes, YARA rules, SAST tools).

- Understanding of software supply chain security standards and frameworks (SLSA, SSDF, etc.).

- Prior public research, CVE credits, or published malware findings.

- Security certifications such as GREM (GIAC Reverse Engineering Malware) or equivalent.

We :

- Strive for excellence in everything we do, prioritizing quality, speed, and impactful outcomes.

- Engage in first principles thinking to debate ideas, test assumptions, and make decisions.

- Put data above opinions, seeking truth and clarity in all our endeavors.

- Embrace a culture of feedback and continuous improvement, assuming good intent in all interactions.

- Celebrate wins as a team, understanding that our collective success is intertwined with the success of our customers.
