**Company:** Solen Software Group **Location:** São Paulo, Brazil **Work Model:** In\-office / Hybrid **Employment Type:** Full\-time **About Solen Software Group** Solen Software Group is an evergreen holding company that acquires and operates proven vertical\-market software businesses with meaningful long\-term growth potential. Solen compounds value over decades, not quarters, and partners with founders to build enduring category leaders across HR tech, fleet telematics, asset management, e\-health, document management, and other mission\-critical software verticals. **About the role** The AI Tech Lead will be the hands\-on engineering leader of Solen's AI Center of Excellence (COE), building and shipping AI\-powered products across our portfolio of operating companies (OpCos). This role is responsible for taking AI initiatives from idea to general availability, setting the engineering standards the COE works by, and building a high\-velocity team that OpCo leaders trust as a delivery partner. You will decompose ambiguous problems into clear technical plans, make the call on speed versus technical debt, and coach engineers to raise the bar on quality and flow. This is a highly technical, hands\-on leadership role based in Brazil, working from our existing office on an in\-office / hybrid basis. **What You Will Do** **AI Delivery Across the Portfolio** * Lead the design, build, and launch of high\-impact AI projects for multiple OpCos, taking each from concept through general availability (GA). * Partner with OpCo product and business leaders to identify AI use cases that create measurable customer value and contribute to portfolio AI revenue targets. * Decompose ambiguous business problems into clear architectures, technical plans, and deliverable milestones. * Remain hands\-on in architecture, code, and technical decision\-making while guiding the team through execution. **Technical Leadership** * Own technical direction for COE projects, including architecture, model and framework selection, and integration with OpCo platforms. * Balance speed of delivery against technical debt, making sound trade\-off decisions and holding firm on non\-negotiables such as security and data privacy. * Tailor security and compliance approaches to each OpCo's environment and customer requirements. **Engineering Standards \& Code Quality** * Define and implement COE engineering standards, including coding guidelines, code review process, testing expectations, and CI/CD checks. * Ensure every new project follows these standards, and build the tooling and review practices that enforce them. * Continuously improve standards as the team, tools, and AI landscape evolve. **Team Productivity** * Implement practices that drive high\-velocity development, including AI\-assisted engineering workflows. * Identify and remove bottlenecks, improve flow, and track delivery metrics that matter. * Coach, mentor, and develop engineers, raising the technical bar across the team. **Cross\-Team Communication** * Establish a clear communication cadence with OpCo leaders on priorities, progress, risks, and outcomes. * Act as the bridge between product and engineering, resolving conflict constructively and keeping stakeholders aligned. * Translate technical concepts and trade\-offs for non\-technical audiences. **Required Qualifications** * Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent experience. * 7\+ years of professional software engineering experience, with at least 2 years in a technical lead or engineering lead role. * Proven track record shipping AI/ML or LLM\-powered products to production and general availability. * Demonstrated ability to take an ambiguous project, decompose it independently, and define the architecture to deliver it. * Hands\-on experience defining and enforcing engineering standards: coding guidelines, code reviews, automated testing, and CI/CD pipelines. * Concrete examples of improving team velocity, removing bottlenecks, and coaching engineers. * Strong experience with modern AI tooling (e.g., LLM APIs, RAG, agents, evaluation frameworks) and cloud platforms (AWS, Azure, or GCP). * Solid understanding of application security and data privacy, and how to apply them in different environments. * Excellent communication and stakeholder management skills, with professional fluency in English. * Based in Brazil and able to work from our office on an in\-office / hybrid basis. **Preferred Qualifications** * Experience in B2B SaaS or vertical software, ideally across multiple products or business units. * Experience leading a Center of Excellence, platform team, or shared engineering function. * Experience with AI\-first development practices and AI coding assistants at team scale. * Experience working with distributed teams across North America and Latin America. **What Success Looks Like** * High\-impact AI projects reach GA for at least 3–5 OpCos and contribute toward the $1M A
