Job description
Role: Application Security Engineer
Location: 100% remote
Duration: 6 – 12 Months
Visa: GCEAD
Role Overview
- Position: Security Consultant
- Core Focus: Software security analysis heavily emphasizing third-party applications introduced by employees.
- Primary Environment: Predominantly Windows software, with some Linux.
Primary Requirement: First-Principle Systems Knowledge
- Candidates must deeply understand how a computer functions at a low level, regardless of the operating system or software stack running on it.
- The ability to explain core concepts fundamental to modern computing is mandatory, as this foundation is required to effectively reason about security.
- Hiring managers will actively filter for this low-level understanding by looking for hands-on work experience, projects, or hobbies in the following areas:
- Compiler or Operating System design.
- Writing a debugger.
- Computer hardware design (especially secure hardware), including hardware interfacing and instrumentation.
- Code optimization.
- Emulation or Virtualization implementation and design (e.g., utilizing frameworks like QEMU for advanced testing or manipulation). Note: Merely using virtualization technologies as an end-user is insufficient.
- Vintage computing.
Technical Responsibilities & Capabilities
- Reverse Engineering & Analysis: Perform reverse engineering on binaries and conduct network analysis (e.g., interception, decryption) to uncover vulnerabilities, hidden data exfiltration, or unauthorized behaviors.
- Tooling: Familiarity with reverse engineering tools like Binary Ninja is a plus, but tool-agnostic capabilities are expected. Candidates who build custom offensive tooling, fuzzing frameworks, or automated testing protocols strongly align with the desired profile.
- Security Validation: Ensure software complies with internal security guidelines and internal policies (e.g., restricting unauthorized network connections).
- Collaboration: Work closely with internal domain experts, platform engineering teams, frontline support, and end users to deliver findings and suggest practical, balanced workarounds.
Experience & Qualifications
- Experience Level: 3–5+ years of relevant experience (mid-to-senior level).
- Valued Backgrounds: Prior experience in network/system administration, broad technical understanding of process flows, or participation in Capture-the-Flag (CTF) competitions.
- Certifications: Not required or prioritized; demonstrable, hands-on skills take strict precedence over formal certifications.
