Job description

From Silver.dev

This is an opportunity for an exceptional, deeply technical engineer from Argentina to join as Founding engineer of a fast-growing startup. You'll be the technical co-leader of the company alongside the founders: owning the product's architecture, setting the engineering bar, and building the team and culture from the ground up, with the ownership and upside that comes with a leadership role this early.

About Convexity

For distributors and manufacturers, growth often means hiring more people to process orders, manage purchasing, and keep up with emails. Convexity changes that. It serves as the source of truth for inventory and an AI operations manager, automatically converting orders from emails and marketplaces into sales orders and invoices, forecasting demand at the SKU level, and telling teams exactly what to buy and when. Customers can also use Convexity directly through ChatGPT, Claude, or Gemini. The goal: inventory management on autopilot.

Responsibilities

You will work in person with the founders in San Francisco and operate with extreme ownership: every technical decision ultimately lands on your desk.

• You will stay deeply hands-on across the whole stack: frontend, backend, data, infrastructure, and AI. You'll own products end-to-end, from the first line of code to production.

• You will own technical architecture and make key product decisions, balancing speed with building systems that scale.

• You will talk directly to customers, understand how distributors actually operate, and turn their problems into shipped features.

• You will help hire and build the engineering team as the company grows.

You might be a good fit if

• You are very technical and have a spiky profile: exceptional depth in at least one area and the potential to grow fast in all of them.

• You've built ambitious systems from zero. Exceptional technical projects matter more to us than pedigree or where you studied.

• You are obsessive about the details, love going deep into hard problems, and care more about the work than about appearances.

• You are high-energy, passionate about what you build, and genuinely good-hearted someone people want to work next to every day.

• You have strong experience with some of: Python, React, TypeScript, APIs and databases.

• You are based in Argentina and willing to relocate to San Francisco.

• You have a C1 English level.
