Cloud Security Engineer 🇦🇷

About The Mobile-First Company

• Most tools for small businesses weren’t built for real operators.
• They were built for employees in offices, not people running a business from their phone.

We’re changing that.

We build mobile-first business software that feels like a consumer app, runs on AI, and spreads like a creator brand.

Our first product, Allo , gives you a second number on your phone, answers missed calls with AI, transcribes everything, and syncs it to your CRM.

• Over 20,000 businesses use it every day.
• Next up: expenses, invoicing, and more.

• We’ve raised +15 million dolars from Base10, Lightspeed, EMBLEM, and 30+ top operators.
• Our team is based in Paris, Buenos Aires , Miami .

What will you do:

• Work side by side with our CTO to own our security and compliance roadmap, from strategy to execution.

Lead our offensive security track with external partners: scope pentests, triage findings and drive the fixes across infrastructure and code.

Partner with our Infra & Platform team to design, harden and scale the backend and cloud infrastructure behind our products.

What you’ll be working on

• Securing our cloud infrastructure (e.g., AWS, Supabase, Cloudflare): IAM, networking, encryption, secrets and logging.

Authentication, authorization and data protection across our apps.

Building security into our CI/CD: code, dependency and secret scanning that keeps pace with a team that deploys every day.

Writing the code, automations and tooling that fix vulnerabilities and keep them from coming back.

Owning our compliance controls (HIPAA, GDPR, SOC 2) and closing the technical gaps.

Monitoring, alerting and incident response for a real-time telephony and AI product.

What we’re looking for

Engineering background:

◦ You started as a software developer and still write production code in languages like Python, Go, TypeScript, Kotlin, Java or similar.

◦ You build tools and automations, not just configure them.

◦ You use AI tools in your daily work to move faster.

2. Cloud & Infrastructure:

◦ Deep hands-on experience with AWS: IAM, VPC and networking, KMS, CloudTrail, GuardDuty or similar.

◦ Infrastructure as Code with Terraform, CDK, Pulumi or similar.

◦ Solid networking fundamentals: DNS, TLS, firewalls, WAF, VPNs.

3. Security:

◦ You have found and fixed real vulnerabilities, from a pentest, an audit or your own monitoring.

◦ Experience with secure CI/CD, secrets management and least-privilege access.

◦ Experience with compliance frameworks (SOC 2, HIPAA, ISO 27001, GDPR) is a plus, not a requirement.

4. How you think

◦ You care about why we build things, not just how.

◦ You ask smart questions, challenge ideas when needed, and help shape what’s next.

◦ You think in terms of user value and business impact.

5. How you work

◦ You communicate clearly, give feedback with no ego, and help others grow.

◦ You move fast, take ownership, and thrive in ambiguity.

◦ You're comfortable working in English — and in a small team with big goals.
