We are looking for a Senior Application Security Engineer with 6+ years of experience to join a small but high-impact security team and bring an engineering-first mindset to application security. You're someone who started as a software engineer or has always been hands-on with code – you read it fluently, write production-quality fixes, and ship them yourself rather than throwing findings over the fence. You'll help automate away manual security work using AI-native tooling so the team can scale through leverage and focus on broader security architecture. This is a rare opportunity to shape how security is built into an engineering organization that's moving fast, innovating with AI, and serving highly regulated customers.
What you will be doing
Contributing production-quality code directly to the application (Node.js/Python) – shipping security fixes and hardening features yourself, not just filing tickets for engineers to action
Building AI-powered automation to eliminate manual security work (e.g., PR analysis, vulnerability triage) so the team can scale faster and focus on higher-leverage architecture work
Managing the HackerOne bug bounty program end-to-end – evaluating submissions, reproducing issues, and closing findings by shipping fixes
Defining secure-by-design patterns and driving security standards across the application architecture, including for AI-integrated product features
Acting as a security reviewer on RFCs and design documents, pairing with engineers to resolve issues at the source rather than blocking them

No applications, no recruiter spam. Just the intro.
A few questions to make sure this role is the right shape for you. Two minutes.
I write the intro, send it to the founder, and handle the back-and-forth.
If they’re a yes, I book the chat. You show up — that’s the whole job-hunt.
