## Job description

## 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](https://www.withallo.com/), 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.

1. 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.

1. 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.

1. 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.

1. 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.

What matters to us

- 4+ years of experience building and operating backend systems in production, with hands-on responsibility for application or infrastructure security.
- You understand production. You consider reliability, observability and recovery alongside security, especially when changes affect live customer [calls.You](http://calls.You)’re proactive, autonomous, and know how to fill the gaps
- You prioritize by real-world risk. You can explain what needs fixing today, what can wait, and why, in terms of our users, their data and our business.
- You’re proactive, autonomous, and know how to fill the gaps
- You can communicate in English, since that's our official language. Most of the team also speaks Spanish and French.
- You’ve worked in product companies

## What we offer

- Competitive salary (in USD or local equivalent)
- Equity package
- 10-day team retreats abroad every year
- Trips to our Hubs (Pairs/Miami/BA) for onboarding and more
- Laptop and work setup of your choice
- Coverage for private health insurance (for US or LATAM hires)
- A tight, ambitious team building something real: fast
