Senior Machine Learning Engineer

Sobre a vaga

We are looking for a Senior ML/AI Engineer to help stabilise and evolve our AI platform while developing and maintaining production-grade Generative AI solutions. This is a hands-on engineering role combining AI application development, backend and platform engineering, and production operations.

O que vais fazer

• Design, build, and maintain production GenAI solutions, including LLM-based applications, RAG pipelines, and multi-step agent workflows
• Own technical delivery across the solution lifecycle, from refining requirements and preparing data through architecture, implementation, evaluation, and deployment
• Develop backend APIs, services, and integrations that connect AI capabilities with business systems and enterprise data sources
• Build evaluation approaches that assess solution quality, relevance, safety, and reliability, using results to guide improvements
• Own solutions in production, including monitoring, troubleshooting, incident resolution, and ongoing improvements to performance, latency, and cost
• Apply sound software engineering practices, including automated testing, version control, CI/CD, containerisation, and clear technical documentation
• Work within established platform, security, and governance standards, integrating with shared services and flagging gaps
• Collaborate with technical and business colleagues to translate requirements into reliable solutions, communicate trade-offs, and share knowledge with less experienced engineers
• Assess emerging GenAI techniques and tools for their practical value to the team's solutions

O que é pedido

• Bachelor's or Master's degree in computer science, artificial intelligence, or a related field
• 4+ years of experience in AI/ML engineering roles, including 2+ years developing GenAI solutions, with demonstrated ownership of production deployment and ongoing operation
• Hands-on experience building complex GenAI applications, including multi-step agent workflows and retrieval-augmented generation
• Strong Python programming skills and experience developing production backend services, APIs, and integrations
• Practical experience with orchestration frameworks such as LangChain, LangGraph, or equivalent tooling
• Experience deploying and operating solutions in cloud environments, using containerisation and CI/CD
• Practical experience evaluating GenAI systems, including designing test cases, assessing failure modes, and checking for regressions as solutions change
• Solid knowledge of relational databases such as PostgreSQL, alongside experience with vector search and retrieval
• Experience applying security, observability, and governance requirements within production solutions
• Strong written and spoken English

Valorizado

• Experience working with shared AI platforms, model gateways, proxies, or API management services
• Exposure to AI-specific platform controls, including rate limits, quotas, gateway policies, and cost monitoring
• Experience integrating AI applications with enterprise systems and retrieving information across multiple data sources
• Familiarity with platforms such as Databricks, Microsoft Foundry, or similar tooling
• Experience with Kubernetes or infrastructure as code
• Ability to help stakeholders refine problems and define measurable success criteria

O que é oferecido

• Permanent contract
• Competitive compensation package based on your experience, including private health insurance
• 22 days of annual leave + 3 additional company days to recharge
• Flexible working hours and a hybrid model that supports balance and collaboration
• Continuous learning opportunities (technical and behavioural development) to support your growth
• Modern, well-equipped office in the heart of Porto
• Free parking for your convenience
