📋 Description

• Lead the technical design, architecture, and delivery of AI solutions, with a focus on AI agents, agentic workflows, automation, and AI-assisted business processes. • Own the end-to-end engineering lifecycle of AI products: discovery, prototyping, evaluation, production implementation, rollout, monitoring, and continuous improvement. • Lead and manage an AI engineering team, including technical direction, task breakdown, mentoring, code reviews, delivery planning, and engineering quality. • Design and implement solutions using AWS AI/ML services, including Amazon Bedrock, Amazon Bedrock AgentCore, Amazon SageMaker, and other AWS services for model hosting, orchestration, data processing, monitoring, and security. • Build and integrate AI applications using technologies such as Python (FastAPI/Flask/Django) or equivalent, along with relevant AI/ML frameworks. • Design agentic systems that can interact with APIs, internal platforms, business workflows, knowledge bases, and external tools in a safe, observable, and controlled way. • Define and implement best practices for LLM application development, including prompt engineering, RAG, tool use, function calling, memory, evaluation, guardrails, and hallucination mitigation. • Drive improvements in internal engineering practices around AI-assisted development, engineering productivity, AI efficiency, automation, and responsible use of AI tools across software delivery. • Work with stakeholders to identify high-value AI use cases, assess feasibility, define success metrics, and prioritize delivery. • Establish engineering standards for AI systems, including code quality, testing, observability, reliability, security, scalability, and maintainability. • Drive MLOps and LLMOps practices, including model lifecycle management, deployment pipelines, monitoring, evaluation, drift detection, and rollback strategies. • Collaborate with DevOps, cloud, security, and platform teams to ensure AI systems are production-ready, compliant, cost-efficient, and operationally stable. • Support rollout and adoption of AI solutions across the organization, including documentation, training, stakeholder communication, and production support. • Evaluate emerging AI technologies, frameworks, models, and vendors, and provide pragmatic recommendations on adoption. • Ensure AI solutions follow responsible AI principles, including data privacy, access control, auditability, fairness, explainability where applicable, and secure handling of sensitive data.

🎯 Requirements

• Minimum 10 years of professional experience in software engineering, data engineering, machine learning engineering, AI engineering, or related technical roles. • At least 3 years of experience leading or managing engineering teams, including technical leadership, mentoring, planning, and delivery ownership. • Strong hands-on experience building production-grade AI, ML, and data-driven systems. • Practical experience with AI agents, agentic workflows, LLM-based applications, workflow automation, tool-calling architectures, and AI orchestration patterns. • Strong knowledge of AWS, including practical experience with cloud-native architectures, Amazon Bedrock, Amazon Bedrock AgentCore, Amazon SageMaker, and related AWS AI/ML services (the more, the better). • Build and integrate AI applications using technologies such as Python (FastAPI/Flask/Django), and relevant AI/ML frameworks. • Experience with advanced LLM frameworks such as LangChain, LlamaIndex, Semantic Kernel, CrewAI, AutoGen, or similar agent/orchestration frameworks. • Experience building RAG systems, including document ingestion, chunking strategies, embeddings, retrieval evaluation, reranking, and grounding techniques. • Solid understanding of machine learning concepts, including supervised/unsupervised learning, model training, feature engineering, evaluation, inference, and model performance metrics. • Experience with MLOps / LLMOps, including CI/CD for ML and AI applications, model deployment, experiment tracking, model/prompt/version management, monitoring, evaluation pipelines, and production rollback strategies. • Experience with vector databases and retrieval/search technologies, such as Amazon OpenSearch, Pinecone, pgvector, or similar. • Experience with model fine-tuning, embedding models, transformer architectures, open-source LLMs, and model benchmarking. • Experience designing APIs, microservices, event-driven systems, and cloud-native backend architectures. • Strong understanding of security and governance requirements for AI systems, including access control, secrets management, data privacy, audit logging, and safe use of sensitive data. • Experience working with cross-functional teams, including product managers, architects, engineers, data scientists, security teams, and business stakeholders. • Ability to move from prototype to production without creating “AI demo theater” — the system must actually work, scale, and survive contact with real users. • Strong communication skills, with the ability to explain complex AI and engineering topics to both technical and non-technical audiences. • Strong ownership mindset, pragmatic decision-making, and ability to balance innovation with delivery discipline.

🏖️ Benefits

• Fast-growing payment company; • Excellent working conditions, casual atmosphere, and state-of-the-art hardware; • Modern, challenging, constantly growing business; • Professional development – books, trainings, certifications, etc.; • Team buildings and fun activities; • 25 days paid holiday, 1 day for every 2 years with us; • Fully distributed and remote.
