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, Allô, 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.
Teeming tracks opportunities at over 24,000 AI startups, then works with you to find (and land) the one you'll love.

Drive the evolution of our backend technology, infrastructure, and AI capabilities to ensure high performance, scalability, and seamless integration for our mobile applications.
What Will You Do
Work side by side with our CTO to build the foundations, the present, and the future of our AI capabilities.
Design and implement systems powered by LLMs that translate directly into user value.
Integrate these AI services with our current backend infrastructure.
Instrument, observe, and optimize AI systems with robust evaluation frameworks.
What you'll be working on
Implementing and maintaining scalable and reliable AI systems using languages like Python, Kotlin, JS or similar.
Prompt engineering, vector embeddings and evaluation tools.
Data modeling and management to optimize the performance and intelligence of our apps.
Working directly with Cloud services (e.g., AWS, Supabase, Cloudflare).
What we're looking for
Backend AI Engineering
Proficiency in backend development with expertise in languages like Python, Kotlin, JS or similar.
Proven delivery of LLM features with LangChain or similar (prompt design, RAG, caching, fine-tuning).
Strong system design, performance tuning, and data-modeling skills.
Systems Architecture
Expertise in designing scalable and maintainable backend architectures, understanding when to apply different architectural patterns.
Ability to instrument, monitor, and troubleshoot AI workloads end-to-end
Performance and data
You know how to build scalable and maintainable code
You care about what to measure and how it impacts business and users
You track behavior, usage, and performance, and improve based on it
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.
Proven delivery and great understanding of LLM features in production.
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 quarter
30-day onboarding in Paris (we cover flights and housing)
Laptop and work setup of your choice
Private health insurance (for US or LATAM hires)
