Cyber Product Research

About Astelia

Astelia helps security teams dramatically reduce the volume of incidents generated by vulnerability management tools. We do this by building a deep, contextual understanding of our customers' networks - turning noise into signal and enabling security teams to focus on what truly matters. We're a small, fast-moving startup with great people who care about impact, craftsmanship, and each other.

About The Role

You’ll work with network and security data from some of the largest enterprises, at the intersection of network security, cloud infrastructure and large-scale data. You’ll be the link between clients’ data and the internals of how Astelia is built, and you’ll understand both deeply so they work together.

This is a hands-on research role. You’ll work closely with R&D, validate and own the quality of what clients receive, and use a data-driven approach to shape how the product evolves.

If you have a cybersecurity mindset, love taking networks apart and digging until things add up, and want a real impact on an early-stage team, we’d love to meet you.

Requirements:

Qualifications

• Experience: 4+ years of hands-on experience as a security analyst, network or security research.
• Research Experience: Proven track record of independent, in-depth research, including security, network and data research. You take an open question, dig into it and reach clear, evidence-backed conclusions.
• Strong Networking Knowledge: Deep understanding of:
• Firewalls, routing, NAT, ACLs and subnets
• Common enterprise network architectures
• Network segmentation and exposure concepts
• Network Analysis: Proven experience reading and analyzing configurations from firewalls and network devices and tracing how traffic actually flows.
• Data Skills: Strong SQL and comfort working with large datasets.
• Scripting: Strong scripting skills, preferably in Python, for analysis, automation and building internal tools.
• Cybersecurity Knowledge: Understanding of vulnerabilities and how they’re exploited.
• Research Mindset: Curious, skeptical and persistent. You don’t stop until the data makes sense.
• Team Mindset: Strong communication skills with both engineers and client security teams, high ownership, and the ability to thrive in a fast-paced startup.
  
  

• Experience with vulnerability management, scanners, asset inventory, risk scoring and remediation workflows.
• Experience with exposure management concepts (attack surface, reachable assets, blast radius).
• Experience with cloud security and cloud networking.
• Experience with ClickHouse, Postgres or other analytical databases.
