Acronis protects every workload — from endpoints to cloud — through the industry's only all-in-one cyber protection platform. Our Threat Research Unit (TRU) sits at the center of that mission: we hunt adversaries, dissect campaigns, and build the detection logic that keeps millions of systems safe.

We're looking for a Cybersecurity Researcher (Labs) who thrives on outsmarting threat actors. Whether your edge is reverse engineering malware, building behavioral detections, investigating insider threats, or responding to live incidents — if you're driven to understand how attacks work and how to stop them, this role is for you.

You'll work alongside researchers, detection engineers, and data scientists across multiple time zones to develop and ship protections that reach customers at scale. You'll also have the autonomy to pursue original research and present your findings to the broader security community.

WHAT YOU'LL DO  

  • Research adversary tactics, techniques, and procedures (TTPs) and translate them into detection and prevention capabilities for Acronis Security and EDR products.

  • Analyze malicious and benign content — executables, scripts, documents, memory dumps, network traffic, exploit chains — to identify indicators and behavioral patterns.

  • Develop, tune, and maintain detection logic, signatures, and behavioral rules across multiple expression languages and rule formats.

  • Monitor and improve automated detection pipelines to maintain high efficacy and low false-positive rates.

  • Track emerging threats through open-source intelligence, telemetry analysis, and threat feeds to ensure coverage keeps pace with the landscape.

  • Collaborate with scan engine and product engineering teams on joint research projects and new security features.

  • Publish original research through blog posts, whitepapers, and conference presentations.

 

WHO WE’RE LOOKING FOR  

  • Deep understanding of modern attack techniques, common malware families, OS internals (Windows required; macOS and Linux are a plus), and network protocols.

  • 5+ years of hands-on experience in one or more of: malware analysis (static, dynamic, behavioral), detection engineering, threat hunting, incident response, or insider threat investigation.

  • Proven ability to develop detection logic — whether that's YARA, Sigma, EQL, KQL, custom behavioral signatures, or something else entirely.

  • Comfortable working with threat intelligence platforms and frameworks: VirusTotal, Shodan, MISP, MITRE ATT&CK, or similar.

  • Software development skills in Python; familiarity with REST APIs, SQL, and regex. C/C++ is a plus.

  • Strong analytical thinking, relentless curiosity, and the motivation to succeed in a fast-paced, distributed environment.

  • Solid written and spoken English.

Nice to have:

  • Experience with proactive threat hunting using EDR/XDR platforms.

  • Background working at a security vendor or on a dedicated threat intelligence team.

  • Familiarity with machine learning approaches to threat detection.

  • Network traffic analysis skills (Wireshark, Zeek).

  • Published security research or conference talks.
