Senior Solutions Engineer

About Primeiro AI

Primeiro AI is building the AI-native operating system for large enterprises in Latin America. Our platform, Primia, connects live to clients' fragmented legacy systems (SAP, Oracle, Microsoft, and custom stacks), 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

We're looking for a Senior Solutions Engineer with deep expertise in enterprise system integration to lead the connection between Primia and our enterprise clients' legacy systems. Connecting Primia to a client's legacy stack is the technical heart of every engagement: you'll sit across from CTOs and CIOs at large companies, negotiate the integration architecture, decide how we connect — which middleware, which connectors — and guide engineering through implementation, bringing the best practices (and avoiding the mistakes) that only come from having done this before.

Responsibilities

1. Design, define, and lead integrations between the Primia platform and clients' enterprise systems, with a strong focus on SAP (ERP, S/4HANA), as well as Oracle, Microsoft, Salesforce, and custom platforms.
2. Execute end-to-end integrations of legacy systems, selecting the appropriate technical mechanisms (middleware, connectors, integration patterns) and justifying the choice, architecture, and trade-offs.
3. Negotiate and define integration architecture directly with clients' technical teams (CTOs, CIOs, architects).
4. Establish the technical scope of each implementation and translate it into an executable plan for the engineering team.
5. Support the engineering team throughout implementation, resolving integration blockers and ensuring connectivity with the client's systems.
6. Act as a credible technical authority in front of clients, presenting solutions and holding high-level conversations with senior stakeholders.
7. Document delivered integrations, including mechanisms, architecture decisions, and trade-offs.

What you'll work with

SAP integration is at the core: connectors, middleware, and integration patterns across SAP PI/PO, SAP CPI, SAP BTP, IDocs, BAPIs, RFCs, and S/4HANA. You'll also work across Oracle (Fusion Middleware, OIC), Microsoft, and custom enterprise systems — building the connections from scratch, not configuring on top of what someone else built.

Requirements

• Proven experience as an SAP integrator (not just building on top of SAP — real, hands-on integration experience is required).
• Track record of end-to-end integrations of enterprise and legacy systems, built from scratch.
• Ability to explain technical decisions: which mechanism was used, why, and with what trade-offs.
• Credibility and presence to present to CTOs/CIOs at large enterprises.
• Native or near-native Spanish in a technical/commercial setting; comfortable working in English internally.
• (Nice to have) Experience with Oracle, Microsoft, and Salesforce, plus an ML background given our product surface.

Benefits

• Competitive senior compensation + equity.
• Direct exposure to the systems of LatAm's largest companies.
• Frontier technical work in integration and AI agents.
