Role

Data & AI Consultant

PT, Lisbon

  • Permanent
  • Digital
  • Product & Engineering
At Efficio, we're not just a consulting firm; we're a team of dedicated experts committed to transforming procurement and supply chain functions. Our mission is to drive sustainable, measurable value for our clients through innovative solutions and deep industry insights. Join us and be part of a dynamic environment where your skills and ideas make a real impact.

Efficio is the world’s largest specialist procurement and supply chain consultancy, with offices across Europe, North America, and the Middle East. We’re a diverse team of over 1,000 individuals, representing more than 60 different nationalities and speaking 40+ languages – and we’re continuing to grow rapidly!

Efficio’s Product & Engineering team is an internal function of 60+ people driving innovation in the high-potential e-Procurement space. They are responsible for the development of software and data solutions and tools that enable our consulting teams to deliver better and faster outcomes to our customers. Product & Engineering is pivotal to scaling our business and services and comprises specialised teams in Applications Development, Data Services, AI and Infrastructure.

We are looking for a Data & AI Consultant to join a fast-growing client-facing technology team. This is not a traditional data engineering role, and it is not a pure consulting role. It sits at the intersection of engineering, AI implementation, technical advisory, and client delivery. 

You will work directly with a major global client, helping them understand, design, and implement AI-enabled solutions within their own data and technology environment. Rather than simply building products in isolation, you will guide stakeholders through the journey from problem definition to roadmap creation, MVP development, and scalable implementation. 

This role is ideal for someone who enjoys both building and advising: someone who can speak confidently with senior stakeholders, translate business problems into technical roadmaps, and work hands-on with Python, AWS, APIs, databases, CI/CD pipelines, and AI models.

What will you be doing?

As a Data & AI Consultant, you will play a key role in shaping and delivering AI-enabled data solutions for a major client. Your responsibilities will vary depending on the workstream, but will typically include: 

  • Working directly with client stakeholders, from senior leaders and board-level audiences to technical teams and day-to-day users, to understand business problems and translate them into practical technical solutions. 

  • Supporting the definition of AI and data workstreams, including requirements gathering, technical discovery, roadmap creation, prioritisation, and implementation planning. 

  • Designing and developing MVPs that demonstrate how AI, data pipelines, APIs, and cloud infrastructure can be used to solve real client problems. 

  • Guiding client and partner engineering teams on how to build, integrate, and scale solutions within their own data pipelines and technology environment. 

  • Acting as a bridge between business stakeholders, product teams, external engineering teams, and internal Efficio specialists. 

  • Advising on the use of AI models within data engineering processes, including prompting, AI engineering patterns, workflow automation, and integration into production pipelines. 

  • Supporting solution design across AWS, Python-based applications, databases, APIs, CI/CD pipelines, and scalable data infrastructure. 

  • Bringing a consulting mindset to delivery: structuring ambiguity, communicating clearly, preparing presentations, and helping stakeholders make informed decisions. 

  • Contributing to Efficio’s broader technology and IP ecosystem, including selected touchpoints with internal tools and products such as contract review and procurement intelligence capabilities. 

  • Experience in a technical consulting, data engineering, AI engineering, analytics engineering, backend engineering, or solution engineering role. 

    • Strong Python skills and experience building robust, maintainable technical solutions. 

    • Experience working with cloud environments, ideally AWS. 

    • Practical understanding of data pipelines, databases, APIs, CI/CD practices, and production-quality engineering. 

    • Familiarity with AI engineering concepts, such as prompt engineering, LLM integration, RAG patterns, model-enabled workflows, or using AI models within data and analytics processes. 

    • The ability to understand complex business problems and translate them into technical roadmaps, implementation plans, and delivery milestones. 

    • Confidence communicating with both technical and non-technical stakeholders, including senior client audiences. 

    • Experience creating technical documentation, presentations, solution designs, or delivery plans. 

    • Comfort working in ambiguity, especially in an early-stage or evolving role where structure is still being defined. 

    • A willingness to be hands-on when needed, whether that means building an MVP, reviewing architecture, working with APIs, or supporting implementation decisions. 

    Who we’re looking for:

    This is an opportunity to join early in the growth of a client-facing AI engineering capability. You will be one of the first hires into this type of role, which means you will have room to shape how we deliver, how we engage with clients, and how we combine consulting with modern AI and data engineering. 

    The role will initially involve a significant amount of client interaction, discovery, requirements gathering, and roadmap development. Over time, it is expected to remain a balanced mix of engineering and client-facing delivery, with approximately half of the work focused on technical implementation and half on stakeholder engagement, presentations, and consulting-style problem solving. 

    You should be comfortable with a role that is still evolving. There will be less predefined structure than in a mature product or engineering team, but there will also be more opportunity to influence the direction of the work. At times, delivery may be demanding due to client deadlines and expectations. 

    Travel requirements are still being confirmed, but candidates should be open to travelling for client meetings when needed. 


    Our collaborative and inclusive culture is what makes us stand out. At Efficio, colleagues with diverse backgrounds, ideas, and viewpoints come together to identify innovative solutions for our clients - and so we're looking for our new team members to bring strong communication, empathy, and relationship-building skills to maintain this culture as we grow.

    We encourage our teams to proactively innovate and challenge the status-quo, backed by strong analytical thinking, creative problem-solving and technical expertise. We’re looking for team members who are passionate about solving real world problems using technology and are focused on delivering faster and better outcomes for our customers.

    Strong opportunities for career growth are an important part of our offering; as such, we love seeing ambition and a proactive approach to shaping your career to your goals and interests.  

    We'd love to hear about any additional skills or experiences you bring to the table. We're particularly interested in:
