Senior Security Engineer

What you'll do

• Threat model new product features and integrations and harden systems with effective controls.
• Operate and evolve the application security toolchain (SAST, dependency and supply-chain checks, secrets scanning) and keep it high-signal for developers.
• Own day-to-day security operations across the detection stack (EDR, SIEM, on-chain monitoring, identity, cloud): triage what fires, resolve what matters, and reduce noise.
• Triage vulnerability and bug-bounty findings by real exposure, drive remediation, and support incident response end to end.
• Take security tooling and projects from evaluation through org-wide rollout, collaborating across engineering, infra and other teams.
• Automate repetitive, judgment-light security work with AI: vulnerability and AppSec workflows, access reviews, SOC 2 and audit evidence collection, vendor due diligence, and recurring reporting.
• Build reusable AI components, Claude skills, and agents that engineering and other functions can adopt.

What you Bring

• 5+ years in hands-on security engineering spanning product or application security and security operations.
• Track record of technical security assessments of software and systems, including system hardening, security policy analysis and implementing effective controls.
• An adversarial mindset: you think like an attacker and pressure-test assumptions, including your own.
• Proficiency in Python, TypeScript, or JavaScript, working with Claude Code, Codex or similar AI tools.
• Hands-on experience applying AI and LLMs to automation and building reusable tooling or components that other engineers adopted.
• Experience owning security projects end to end, from vendor selection through org-wide rollout, across multiple teams.
• Experience securing high-value or high-throughput transaction systems.
• Clear communication: you explain risk plainly and drive findings to closure.

• Crypto/blockchain security experience.
