At Coodex.ai, we build AI-powered platforms that reimagine how mission-critical industries operate — from hyperscale data centers to oil & gas megaprojects. Our flagship platform, Meris, transforms commissioning from weeks into a single day, with unmatched traceability, accuracy, and auditability. We’re looking for a Senior Software Engineer / Forward Deployed Engineer to join our São Paulo office and work directly with leadership, clients, and field engineers. This role blends deep technical work with high-touch industry engagement — you won’t just write code, you’ll design solutions on the ground, where failure isn’t an option. What You’ll Do Own the technical direction for Meris features and integrations, from architecture to deployment, in environments where uptime, accuracy, and security are non-negotiable. Embed with clients (in person and remotely) to understand operational workflows, uncover bottlenecks, and translate them into scalable, AI-driven solutions. Lead and mentor engineers, driving excellence in code quality, architecture decisions, and agile delivery. Build robust full-stack applications using Node.js, Type Script, Nest JS, Next.js, and modern front-end practices. Integrate advanced AI workflows, including LLM-powered features, document intelligence, and observability pipelines (Langfuse or similar). Collaborate with product leadership to shape technical strategy, roadmap priorities, and deployment plans across multiple high-value clients. Partner with field engineers to ensure the product thrives in the toughest real-world conditions — from offshore rigs to hyperscale data centers. What We’re Looking For 7+ years of professional software engineering experience, including 3+ years in a tech lead or client-facing engineering role. Proven expertise in full-stack development with Node.js/Type Script, Nest JS, and Next.js. Strong experience architecting distributed, cloud-native systems (AWS or GCP preferred). Ability to work close to the problem — comfortable visiting client sites, troubleshooting live deployments, and iterating fast. Familiarity with AI/ML integration (LLM SDKs, data pipelines, vector databases) is a plus. Exceptional communication skills — able to engage with executives, engineers, and operators alike. Based in São Paulo or willing to relocate for a hybrid model with on-site client visits. About Us Coodex.ai combines deep industry expertise with advanced AI to deliver transformative solutions — we’re setting new standards in efficiency and innovation.
