About the Role

We're looking for a Head of Security to own security across Labhouse. Reporting to the CTO and as our first dedicated security hire, you'll assess our security end to end, tackle the biggest threats yourself, and sequence the program build by risk, starting with application security. You'll work closely with engineering, product and the founders, and build the team as we grow. Your responsibilities will include:

- Application security. Build a secure development lifecycle with threat modeling and code review, and protect our mobile apps against reverse engineering, API abuse, account takeover and in-app purchase fraud.

- Cloud and infrastructure. Harden our cloud and CI/CD with infrastructure as code, least-privilege access and secrets management.

- Company security. SSO, MFA, device management, access reviews, and onboarding and offboarding for employees and vendors.

- Vulnerabilities. Find and fix weaknesses in our code and in the tech we depend on, with pentests and a bug bounty or disclosure program.

- Detection and response. Logging, monitoring, alerting, incident playbooks, post-mortems and, when needed, communication with users.

- AI security. Guardrails against prompt injection and data leakage to AI vendors, and safe use of AI tools and agents internally.

- Data protection and privacy. Encryption, data classification and retention, GDPR and app store privacy requirements.

- Governance and compliance. Policies, risk assessments, vendor risk, and certifications like SOC 2 or ISO 27001.

ABOUT YOU

Experience:

- You've led security at a fast-growing tech company as Head of Security, Security Lead or similar, ideally as the first or an early security hire.

- Deep hands-on application security experience, including iOS and Android apps and their backend APIs. You know the OWASP MASVS and OWASP Top 10 well.

- Strong cloud security skills on GCP: IAM, networking, secrets and infrastructure as code.

- You read and review code, and write your own tools and automation, for example in Python or Go.

- You've handled real security incidents from detection to post-mortem.

- Pragmatic about risk: you focus on what matters most, know when to move fast and when to slow down, and make security easy for engineers rather than a blocker.

- Self-driven, and comfortable taking ownership from day one.

- You use AI tools daily and understand the risks they bring.

Problem-solving and ownership:

- Excellent analytical skills and the ability to prioritize risks pragmatically in a fast-moving environment.

- Self-driven, entrepreneurial attitude with the ability to work autonomously and take ownership from day one.

- Strong judgment on when to move fast and when to slow down for security.

Communication:

- Good level of spoken and written English.

- Ability to explain security risks clearly to technical and non-technical colleagues and to collaborate with engineering, product, and IT.

Nice to Have:

- Mobile reverse engineering and anti-tampering (Frida, Jadx, Ghidra, app hardening tools).

- Fighting fraud in subscription apps: receipt validation, App Attest, Play Integrity and bot protection.

- Securing LLM-powered features, AI agents and third-party AI APIs (OWASP Top 10 for LLMs, red-teaming).

- Securing apps that handle sensitive user data, such as financial or document data.

- Led a SOC 2 or ISO 27001 certification, or know GDPR, HIPAA, NIS2 and the AI Act well.

- Certifications such as OSCP, OSWE, GMOB or CISSP. Useful, not required.

- A track record in bug bounties, CVEs, open-source security tools or conference talks.

APPLICATION QUESTIONS

- Your first 90 days. You join as our first security hire. We ship several consumer subscription apps on iOS and Android, with a GCP backend and LLM-powered features. What do you look at first, and what are the top three risks you’d expect to find?

- AI risk. How do you use AI tools in your own work? What’s one risk they introduce at a company like ours, and how would you mitigate it without banning them?

- Which 2–3 sources do you rely on most to stay current on mobile, cloud or AI security, and what’s something useful you learned from one of them recently?

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
