Department: Tech - Software EngineeringLocation: Warsaw, PolandDescriptionBased in Warsaw, you will work as part of a growing AI software team that is building innovative intelligent solutions. As a Senior AI Engineer, you will architect and develop AI-driven services using large language models, Retrieval Augmented Generation (RAG) pipelines, and multi-agent orchestration (using frameworks like LangGraph) to power key products and internal tools at Aurora.You will turn product ideas into reality by designing robust AI systems from concept to deployment, ensuring they are scalable, reliable, and deliver value for end-users. This role involves working closely with our product managers and stakeholders to integrate AI capabilities into our software platforms. You will be deploying these solutions on cloud infrastructure (including AWS Lambdas for serverless compute) and using modern MLOps practices to monitor and improve them in production.As a senior member of the team, you will also provide technical leadership, driving architectural decisions, mentoring junior engineers, and championing best practices in AI development. You will also act as a key evangelist for AI-assisted engineering to ensure that Aurora leverages AI tooling effectively to achieve engineering excellence.Key ResponsibilitiesDesign and develop AI solutions, taking end-to-end ownership of AI featuresBuild and maintain RAG pipelines, agentic orchestration, developing agent-based systems for complex multi-step tasks. Establish robust evaluation methods to measure the quality of our solutions, and its component partsIdentify and evaluate new data sources, design robust, scalable data pipelinesDeploy and scale AI solutions on AWS cloud infrastructureWork closely with the broader software engineering team and stakeholders (internal and external) to innovate highly effective solutionsMentor and coach junior and mid-level engineers, fostering their growthMonitor the performance and accuracy of deployed AI solutions and iterate to improve themChampion a culture of innovation, continuous learning, and operational excellenceSkills, Knowledge and ExpertiseRequired attributes:Extensive experience in AI/ML development, 5+ years building complex software solutions with a focus on machine learning and AIStrong expertise in Python programming. Experience with ML frameworks such as scikit-learn, PyTorch, or TensorFlow is expected. Familiarity with Node/TypeScript is a plusHands-on experience with modern AI/LLM tooling. We are looking for comfort with frameworks and libraries like LangGraph for building LLM applicationsProven experience deploying and operating AI solutions on cloud platforms (AWS preferred). You have used cloud services like AWS Lambda (or EC2/ECS) to host models or run AI workloads, and are familiar with data storage options (S3, databases). Experience with CI/CD pipelines for rapid deployment, containerisation (Docker), and automating infrastructure (Terraform/CloudFormation or similar) is required to manage our AI services lifecycleExceptional analytical and problem-solving skills. You can break down ambiguous problems (like improving an AI models relevance or figuring out why a pipeline is slow) and iterate to develop effective solutionsDemonstrated ability to design and interpret complex quantitative analyses, using prototypes to translating insights into actionable strategies for business and product teams. Experience mentoring junior engineers or data scientists (providing guidance, code reviews, and fostering best practices) is required, as this role will help shape the growth of our AI teamExcellent communication and collaboration abilities. You can effectively communicate complex AI concepts to different audiences, whether its explaining model results and limitations to product stakeholders or discussing technical details with fellow engineersDesirable attributes:A Masters or PhD in a relevant field (Computer Science, AI, Machine Learning, etc.) is a plusBackground in the energy sector or similar domains is not required, but familiarity with handling time-series data, simulation models, or financial/market data could be beneficial since our company operates in the energy market spaceWhile your focus is AI, any experience building front-ends or full-stack applications can be helpful, as it indicates you understand how AI features need to plug into a productWhat we offerSome of the benefits we include are:Private Medical InsuranceVoluntary pension schemeVoluntary group life insurance at corporate rateEmployee Assistance Programme (EAP)Multi-sport CardAt AER, we are committed to offering flexibility in the way we work.
