About the role

We are looking for a Platform / Solution Architect to support the delivery team on GCP and to take the development environment into its next phase. The role combines hands-on architectural design with strong stakeholder navigation across a large, complex organisation.

Key Responsibilities:

• Own architectural design and design decisions for the development environment on GCP
• Design a generic, reusable platform layer that new projects can adopt, abstracting away common infrastructure and integration concerns
• Align design and timelines with other project and product teams, gathering the input required to make sound architectural choices
• Secure the support the delivery team needs - organisational networking is a core part of the role, not a side activity
• Contribute to the governance model discussion around platform ownership and adoption (driven by another team; alignment required)
• Support data and AI/ML use cases where relevant, including pipeline and integration design
• Provide light Product Owner support where needed to keep the team unblocked
• Maintain and extend the existing communication and stakeholder map

Requirements:

• Proven experience as a Platform Architect, Solution Architect or Technical Lead on cloud platform initiatives
• Strong GCP expertise - this is the target platform and the primary technical requirement
• Demonstrated experience building generic, reusable platform capabilities rather than one-off project solutions
• Excellent communication skills and tenacity - the ability to identify the right people in a large, complex organisation and persist until the required information is obtained
• Solution and systems design, including data modelling and systems integration
• Experience aligning architecture and timelines across multiple product and project teams
• Comfortable operating with incomplete information and driving clarity through stakeholder engagement
• Strong Python
• English at professional working level (C1)

Nice to have:

• Infrastructure as code (Terraform) and CI/CD pipeline design; DevOps practices
• Exposure to platform governance models and adoption frameworks
• Experience delivering AI/ML or NLP solutions into production — not only proof-of-concept work
• MLOps / ModelOps experience, including maturity assessment of DataOps-DevOps-MLOps setups
• Architecture modelling notation (e.g. ArchiMate) and structured analysis and design techniques
• Experience in Product Owner or delivery-facing roles
• Coaching and mentoring of junior engineers
• Critical Success Factors

Perks and benefits:

• Comprehensive benefits - enjoy Udemy for Business, private medical care, Multisport card, veterinary package, language lessons, and shopping vouchers.
• Flexibility - adaptable working hours and remote/hybrid work options to suit your lifestyle & location.
• Career growth - access opportunities for professional development and learning, including perks related to our official partnerships with global IT giants: Microsoft, AWS, Snowflake, Salesforce & more.
• Global collaboration - work with a diverse, international team.
• Innovative environment - be part of a forward-thinking and growth-oriented workplace.
• Engaging community - Work with passionate professionals and participate in team-building events, hackathons, and CSR initiatives to make an impact beyond work.
• Team-building events including our company tradition (annual company event in Mazury).
• A pleasant surprise to start your journey with us in the form of a welcome pack.

Recruitment process:

• HR call
• Technical Interview
• Interview with the dedicated Client
