About Zanskar Research

Zanskar Research is a Bengaluru-based systematic trading and technology firm. We build proprietary trading and market-making strategies across asset classes and exchanges, and run them on technology we build in-house: order and risk management systems, exchange co-located infrastructure and low-latency execution systems.

About the internship

We're looking for B.Tech students and recent graduates with a genuine interest in cybersecurity to join our security team as interns. This is an immediate requirement. You'll work on real systems alongside experienced engineers, learning how a trading firm defends its infrastructure, its people and its data.

You'll get hands-on exposure to both sides of security: how attackers think and operate, and how defenders detect, respond and harden systems against them.

What you'll do

1. Monitor Linux systems and review logs (journalctl, /var/log) to spot suspicious activity and misconfigurations
2. Investigate network traffic with tools like tcpdump, ss and dig to trace connectivity and security issues to their root cause
3. Review access controls, file permissions, users and groups, applying the principle of least privilege
4. Help assess applications and services against common risks, including the OWASP Top 10
5. Support both defensive (Blue Team) and offensive (Red Team) exercises, and learn how the two work together to strengthen security
6. Assist with certificate and TLS hygiene, and with identity and access workflows
7. Write scripts to automate routine security checks
8. Document findings clearly and take part in reviews with the security and infrastructure teams

What we're looking for




- Pursuing or recently completed a B.Tech in Computer Science, Cybersecurity, Information Science, Electronics or a related field
- Linux basics: comfortable using the shell; understands file permissions, users and groups; can read logs (journalctl, /var/log) and manage systemd services
- Networking fundamentals: TCP/IP, subnetting and CIDR, routing basics, what NAT does and how DNS resolves a name; can use ping, traceroute, dig, ss/netstat and tcpdump
- Security fundamentals: the difference between authentication and authorization, least privilege, common attack types (phishing, credential theft, lateral movement) and the OWASP Top 10 at a basic level
- Cryptography: symmetric vs asymmetric encryption, and where cryptography is used in real systems
- Blue Team vs Red Team: what each does, the common tools on each side, and how they work together in an organisation
- Strong problem-solving skills and attention to detail
- Available to join immediately and work onsite in Bangalore for the full internship duration

Nice to have
- Identity: some exposure to OAuth2/OIDC, SAML or LDAP/Active Directory
- PKI/TLS: understands certificates, certificate authorities, certificate chains and why certificates expire
- CTF experience: especially in forensics, network or misc categories
- Scripting experience in Python or Bash

What you'll get
- Hands-on experience securing real production systems at a trading firm
- Exposure to both Blue Team and Red Team work
- Mentorship from experienced security and infrastructure engineers
- A view into how low-latency trading infrastructure is built and protected
- A Pre-Placement Offer for a full time role, based on your performance during the internship
