API Solutions Engineer / Pre-Sales Engineer

About the Company: Our client is an AI-powered dubbing and voice localization platform built for enterprise. Their technology enables companies to dub, translate, and voice-over content at scale using AI - delivering authentic, natural-sounding audio across dozens of languages. The platform is API-first, working with global enterprise brands across e-commerce, logistics, and media. About the Role: We are seeking a technically adept API Solutions / Pre-Sales Engineer in Brazil to drive integration and close deals across global markets, with a focus on the expanding Brazilian region. Sitting between technical delivery and sales, you will run discovery, build proof-of-concept (POC) integrations, test API endpoints, and unblock prospective enterprise customers. What You'll be Doing: • Technical Pre-Sales & Onboarding: Lead discovery calls with technical and non-technical stakeholders, map client architecture, and run POC integrations from initial scoping to final sign-off. • API & Workflow Integration: Support clients building on the platform API. Inspect documentation, test endpoints, and eliminate technical blockers across CRMs, delivery systems, and automations. • AI-Assisted Prototyping: Use low-code tools and modern AI assistants (Claude, Gemini, ChatGPT) to rapidly spin up lightweight demos and prototype workflows without needing production-grade code. • Cross-Functional Bridge: Translate complex client requirements into clear technical briefs for internal Product and Engineering teams. What Were Looking For: • Experience: 3+ years in a technical client-facing role (e.g., Solutions Engineer, Integration Engineer, Pre-Sales Engineer) or a Software Developer looking to step into a client-facing position. • API & Tech Fundamentals: Hands-on experience working with APIs (REST, Postman/cURL, Webhooks) and basic scripting/programming skills (JavaScript, Python). • AI & Automation Tools: Familiarity with AI tools, prompt engineering, and low-code integration platforms (Zapier, Make, Stitch). • CRM & RevOps Exposure: Exposure to CRM platforms like HubSpot or Salesforce. • Languages: Native/fluent Portuguese and business-fluent (written and spoken) English. • Soft Skills: Strong consultative communication skills with the ability to manage your own pipeline in an autonomous, remote setup.
