Job Description
AI Engineer
Darwoft
Role Description This role requires full-time dedication, with clear priority given to Darwoft projects during the established working hours. It is not compatible with other full-time professional engagements. Any additional professional activities must be disclosed in advance and must not interfere with the responsibilities or working hours of this role. We’re partnering with a fast-growing fintech project focused on building an AI-powered conversational platform used by thousands of users in the United States. The product goes far beyond traditional chatbots, leveraging Large Language Models (LLMs) and autonomous AI agents to handle complex, multi-step workflows related to financial operations. We’re looking for a Senior AI Engineer to join a core AI initiative, working hands-on on the design, development, and scaling of agentic systems in production. In this role, you’ll help evolve conversational experiences into advanced multi-agent architectures capable of reasoning, planning, and executing actions autonomously. Your work will have direct impact on real users and real business outcomes. What You’ll Be Doing - Design, build, test, and deploy autonomous AI agents using Python and modern agentic frameworks. - Develop LLM-based systems that go beyond simple Q&A, enabling reasoning, planning, and execution across multi-step workflows. - Implement Retrieval-Augmented Generation (RAG) pipelines using vector databases to ensure accurate, grounded responses. - Integrate AI agents with internal services, APIs, and production systems in collaboration with engineering and product teams. - Build evaluation, monitoring, and optimization pipelines for LLM-powered systems, focusing on accuracy, latency, reliability, and cost. - Apply advanced prompt engineering techniques and tool/function calling to enhance agent capabilities. - Stay current with the latest advancements in Generative AI, LLMs, and agentic architectures, applying best practices to production systems. Qualifications - 5+ years of experience in professional software development. - 2+ years of hands-on experience building and deploying AI / Generative AI solutions in production. - Strong proficiency in Python. - Solid experience working with LLMs and agentic frameworks (OpenAI SDK, LangChain, LlamaIndex, CrewAI, or similar). - Proven experience with agentic systems, including memory/state management and multi-agent workflows. - Experience working with vector databases and RAG-based architectures. - Strong understanding of software engineering fundamentals: Git, testing, CI/CD pipelines. - Ability to translate business requirements into scalable, maintainable technical solutions. - Strong communication skills in English within a fully remote environment. Nice to Have - Experience in fintech, payments, fraud detection, or financial platforms. - Experience evaluating and optimizing LLM systems in production (A/B testing, observability). - Contributions to open-source projects or public technical repositories. - Experience working in fast-paced, high-growth product environments. Benefits - Contractor agreement with payment in USD. - 100% remote work. - Argentina's public holidays. - English classes. - Referral program. - Access to learning platforms.

Senior Fullstack Applied AI Engineer
MAIAEmpowering the Mittelstand through AI-powered SaaS Solutions.
• You build and evolve MAIA's core product capabilities. • Your primary focus is backend and AI systems - RAG pipelines, retrieval strategies, agentic workflows, and LLM integrations. • You also implement the frontend changes needed to ship features end-to-end, while backend remains your main area of work. • You design, implement, and ship features from discovery to production rollout, with a strong focus on backend and AI functionality. • You build and iterate on RAG pipelines, retrieval strategies, and LLM integrations, making pragmatic tradeoffs across quality, latency, and cost. • You build evaluation approaches for LLM features - quality gates, regression detection, and observability that makes non-deterministic systems debuggable. • You implement frontend changes needed to ship features end-to-end - simple, intuitive UI work that unblocks delivery, typically a small portion of total effort. • You proactively scout new technologies and approaches, translate findings into production-ready solutions, and push the team's understanding of what is possible. • You collaborate closely with Product, DevOps, and customer-facing teams to turn requirements into high-quality, maintainable software.
• Develop end-to-end Generative AI solutions, from technical design to production deployment and operation. • Lead or support the creation of copilots, automations, and assistants for clients and internal teams, ensuring quality, security, and scalability. • Evolve the LLMOps platform with a focus on governance, traceability, observability, cost, and security. • Work collaboratively with architecture, engineering, product, and operations teams to define and implement solutions with direct business impact. • Define and disseminate CI/CD best practices applied to Generative AI, in on-premises and cloud environments. • Investigate production failures and incidents, conduct root cause analysis, and propose structural improvements. • Promote technical best practices, perform code reviews, standardize solutions, and share knowledge across teams.
• Implement AI-powered product features and workflows based on specifications from senior engineers. • Write, iterate on, and manage production prompt templates, following established patterns for dynamic prompting and context injection. • Integrate structured output schemas (JSON mode, function calling, Zod/JSON schemas) to ensure AI responses are predictable and application-ready. • Build and maintain output enforcement mechanisms such as validators and repair loops under senior guidance. • Participate in prompt experimentation workflows — drafting variants, running A/B tests across models via OpenRouter, and documenting results. • Contribute to evaluation pipelines and help score prompt/model quality using Langfuse. • Write clean, maintainable TypeScript code within the Next.js / Node.js stack. • Participate in code reviews and incorporate feedback. • Document technical decisions and system behaviour to support knowledge sharing. • Collaborate with product, growth, data, and billing teams to deliver features on time.
