About Primero AI

Primero AI is building the AI-native operating system for Latin America's largest enterprises. Our platform, Primia, connects live to the fragmented systems (Microsoft, Oracle, SAP, and custom stacks) of companies with $250M+ in revenue, normalizes them into a common ontology, and runs custom AI agents on top. We've raised US$16M from General Catalyst, Kaszek, 8VC, and Conviction. Our goal: to become the Palantir of Latin America.

About the role

AI Engineering at Primero is a blend of Product and Software Engineering. We're a small team where everyone wears many hats, so we're looking for engineers who can do a bit of everything and switch context quickly. You'll build Primia — our data and intelligence platform — and deploy the AI agents that run on top of our clients' systems, owning projects end-to-end.

Responsibilities

1. Design, develop, and deploy custom AI agents that operate over clients' information systems.
2. Build and maintain the Primia platform, including user interfaces, backend services, data ingestion and transformation pipelines, semantic models, alerting systems, and visualization dashboards.
3. Develop integrations with clients' enterprise and legacy systems, including ERPs, databases, APIs, and third-party platforms.
4. Make technical architecture decisions on assigned projects, including technology selection, component design, and solution definition.
5. Own assigned projects from end to end — from technical requirements gathering through production deployment with the client.
6. Participate in daily engineering stand-ups, reporting progress, blockers, and priorities.
7. Collaborate with the Deployments team on project tracking, scope definition, and meeting client-agreed delivery dates.
8. Interact directly with clients when the project requires it — for technical discovery, solution validation, and implementation support.
9. Participate in defining and prioritizing product features, in coordination with the founding team and design.
10. Test, validate, and document delivered work.

Requirements

• 0–6 years of professional experience.
• Ability to work across the full stack: front-end, back-end, data, and integration.
• Strong problem-solving, fast learning, and the drive to go beyond the minimum — we love candidates with personal projects built out of a genuine love for coding.
• Full-time availability and willingness to work 100% on-site in our Mexico City office.
• Must be able to code end-to-end (AI-assisted is fine, but you need to program from start to finish — there's a technical assessment in the process).

Our stack (not a requirement): TypeScript, React, Next.js, Python, SQL, Prisma, Postgres, dbt, Supabase. We value critical thinking and the ability to learn any stack a project needs.

Benefits

• Top-of-market compensation in Mexico, competitive equity, and performance bonuses.
• Direct exposure to complex problems at the region's leading companies.
• Frontier technical work in data, infrastructure, and AI agents.
