🎯 The Role

We are building a first-of-its-kind consumer membership ecosystem from the ground up — and when you're serving 100M+ users across iOS, Android, and web, security has to be built in from day one, not bolted on later. As our Staff Embedded Mobile & Product Security Engineer, you will be the foundational security hire on the Security team, embedded directly with product and mobile squads to ship features that are secure by design rather than secured after the fact.

✅ Key Responsibilities

• Embed directly with mobile and product squads — membership app (iOS/Android), marketplace, data & identity — to threat-model, review, and harden features before they ship.
• Run the pen testing program — hands-on offensive work spanning mobile (static/dynamic analysis, binary/reverse engineering, on-device attack surface) and web/API, plus coordination of external engagements — and turn findings into fixed issues, not tickets in a backlog.
• Architect the security controls and documentation that meet partner security requirements, so partnership deals close on our schedule.
• Set the security baseline for a zero-to-one, AI-native stack: coding agents, model and prompt security, mobile AI features, and the new attack surface that comes with AI-native products.
• Write the playbook — mobile and product security standards, guardrails, and the \"paved road\" — so as the org scales, secure is the easy path.

📌 Required Qualifications

• Embedded Builder: You've been the security engineer on a product or mobile team, not just a reviewer at the gate. You write code, file PRs, and ship fixes yourself when it's the fastest path.
• Partner-Compliance Fluent: You've architected against partner security frameworks (or equivalents — SOC 2, PCI, vendor security reviews, mobile app store security requirements) and know how to translate requirements into real controls without theater.
• AI-Native: You aren't just curious about AI; you are burning through tokens, using coding agents daily, and thinking about how AI changes both how we build and what we have to defend — including on-device and mobile AI features.
• Scrappy & Scaled: You have the startup experience to build from zero with a nimble team, plus the big-tech exposure to know what breaks when a product hits massive scale.
• Action-Oriented: You thrive in ambiguity and prefer shipping controls over writing policy. You'd rather land a fix than run a meeting.

⭐ Desirable Experience

🎁 Benefits

• Competitive Salary
• Generous Medical (Blue Cross Blue Shield), Dental, Vision and company-paid Life Insurance
• Company contributions to employee Health Savings Accounts (HSA)
• 401k Plan with Safe Harbor company-matching
• Flexible vacation policy and paid company holidays
• Company-provided technology package
• Relocation assistance where applicable, including travel and company-provided housing for the first 90 days
