The Role:

As a Senior Full Stack Engineer at Simple Machines, you'll be at the heart of groundbreaking projects, collaborating closely with both our talented internal team and forward-thinking clients. In this hands-on role, you'll drive the development of sophisticated, scalable solutions across the full technology stack—from intuitive frontends and robust backends to powerful data pipelines and resilient infrastructure. If you're passionate about solving complex problems and pushing the boundaries of what's possible, this role offers the perfect platform for you to make a real impact.

Technical Responsibilities:

• Responsible for design and technical development of backend services for a highly scalable marketing platform.
• Responsible for designing the APIs, applications, and infrastructure the team develops, and documenting the technical requirements and design for the client.
• Responsible for end-to-end delivery and support, including build, automation, deployment, and operations, for everything that is developed.
• Partner with client stakeholders, and team members, to gather business requirements, collaborate on design decisions, and translate them into technical and design requirements.
• Operate within an iterative delivery team using Agile delivery tools and practices.
• Hybrid remote and in-person collaboration with the delivery team and client stakeholders.

Applications Conditions:

• Must have full working rights for Poland - Sponsorship is not available.
• Reside close to Warsaw to attend team meetings in person.

About the team:

As we scale our EMEA engineering operations, this role will be remote-based, assigned to our UK leadership team and will focus on supporting our UK-based clients. While you'll enjoy the flexibility of working remotely, you'll be closely aligned with our UK delivery teams and client stakeholders, ensuring time-zone overlap and easier collaboration.

Each team member has varying degrees of strength in each area, but all work together across the full stack and assist one another to learn and contribute.

The engineering team enjoys a high degree of autonomy over technical design and actively engages with stakeholders to design solutions. They also actively engage with data scientists and other teams to design and document cross-system solutions.
