This position is open to candidates based in Argentina/Uruguay only.

High-level overview

We’re looking for high-agency, hard-working, smart, creative individuals ready to do their best work and make a real impact.

We’re hiring a Senior Engineer to own major product surfaces across web and mobile and to raise the bar on delivery. You will ship code daily, but you will also be a leader driving execution: turn product engineering priorities into a clear plan, coordinate dependencies, and ship safely without regressions or surprises.

This is a rare opportunity to join early at a startup with strong product-market fit. If you’re an A-player with exceptional work ethic who wants a defining role in a high-growth AI company, we want to hear from you. We’re not for everyone, and that’s by design.

Why you’ll love this role

1. Real ownership over product surfaces and delivery outcomes, not just implementation

2. Challenging, interesting surfaces: dynamic text, voice, and video AI conversations across branded web and mobile apps today, with no limits on what this can become in the future

3. High-stakes launches in a fast-paced, creative environment to ship and create world-class products

4. A high-agency team where strong operators move fast and grow fast

The Role

Stack: Next.js + React (web), React Native (Expo), Github Actions & Docker, Azure Cloud, SDK, Prisma, Vercel, Stripe

A hands-on Staff Product Engineer who owns key product surfaces across web and mobile and raises our shipping bar.

You will:

• Own a meaningful subset of product surfaces end-to-end and ship meaningful code weekly.

• Turn priorities into clear execution plans: milestones, sequencing, owners, and ETAs.

• Coordinate dependencies proactively with Paolo and the engineering lead so launches do not surprise anyone.

• Raise release quality: staging validation, deploy readiness, fewer regressions, and clean rollbacks.

What you’ll do

1) Product surface ownership (core)

You will own a subset of:

• Web app customer dashboard and onboarding flows (Next.js/React/TypeScript)

• Branded React Native mobile apps shipped

• Billing and monetization UX: subscriptions, entitlements, Stripe, Stripe Connect

• Auth and identity flows, including dynamic authentication patterns

• Automations and internal tooling that reduce manual ops work

2) Delivery leadership (core)

• Convert ambiguity into a plan with tradeoffs, sequencing, and realistic ETAs.

• Keep work visible with crisp written updates, quick demos, and early risk callouts.

• Drive cross-team coordination so engineering is not a set of silos.

3) Reliability and shipping discipline (core)

• Improve staging validation, deploy readiness, and QA loops for product changes.

• Reduce regressions and rework by making shipping repeatable and safer.

• Participate in incidents when needed and drive prevention so issues do not repeat.

4) Branded app release scale (important)

• Help drive the path to scalable mobile releases across multiple branded apps.

• Reduce manual release overhead and create repeatable workflows.

What you will not do

You will not be a people manager initially.

• You will not be a ticket-taker waiting for perfect specs.

• You will not avoid ownership when something breaks.

Who you are

• Owner mindset: you take responsibility for outcomes and drive things to completion.

• Execution machine: you out-prepare and out-communicate. No surprises.

• High standards: you ship fast and you do not ship sloppy.

• Calm under pressure: you handle incidents and harden systems after.

• Strong communicator: owners, ETAs, risks, and status are always clear in writing.

Qualifications (must-haves)

• Proven Staff-level ownership of product surfaces in production.

• Strong Next.js/React and React Native experience.

• You love Claude Code and AI coding tools.

• Experience driving cross-team execution: planning, sequencing, dependencies, delivery visibility.

• Strong release instincts: staging validation, careful rollout, rollback thinking.

• You thrive in a small team with high urgency and high accountability.

• Startup experience shipping to real users under real constraints.

Good to have

• Mobile CI/CD or multi-app release workflows.

• Prisma experience and strong data modeling instincts.

• Stripe and Stripe Connect (or similar payments plus entitlements/payouts).

• Complex auth experience in multi-tenant products.

How we work

• Work is planned in Linear with owners, milestones, and ETAs.

• Progress stays visible through daily async updates and frequent demos.

• Production changes follow a disciplined deploy process with staging validation and approvals.

• We move fast, but we do not accept shipping that breaks other teams.
