About this role
Software Engineer – Security & Infrastructure 🇦🇷
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
- Backend Engineering:
- Proficiency in backend development with expertise in languages like Kotlin, Java, Go, Python or similar.
- Track record of building and maintaining scalable and reliable backend systems.
- Experience with AI is a strong plus, especially in applying models to real-world product use cases and optimizing performance in production environments.
- Security:
- Hands-on security work in production: you’ve fixed vulnerabilities, implemented authentication and authorization (OAuth, JWT, RBAC), or worked in a security, fraud or platform team.
- Strong knowledge of secure coding practices and the OWASP Top 10.
- Security work beyond your day job (CTFs, bug bounties, certifications, side projects) is a strong plus.
- Infrastructure:
- Hands-on experience with AWS or a similar cloud, networking and production environments.
- Familiarity with Infrastructure as Code, CI/CD and monitoring tools like New Relic or Datadog.
- 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.
- 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
- You’ve worked in product companies
- 4+ years of experience designing and building high-performance systems used by millions.
- 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.
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
