• Implementing scalable CI/CD processes, containerisation with Docker, and deployments on Kubernetes or bare metal.
• Mentoring and pairing with fellow engineers to share best practices and empower the team to deliver their best work.
• Collaborating with Machine Learning and Data Science teams to operationalise agentic software and advanced AI tooling.

Who we're looking for

• You possess strong hands-on experience in application development and a solid understanding of modern system architecture and design.
• You have a proven track record of shipping code used by paying customers in both Python and a compiled language.
• You are highly skilled in DevOps practices, including GitLab CI/CD, Docker, and managing applications in production environments.
• You bring experience with agentic software development and a passion for understanding and solving complex customer problems.
• You thrive when acting as a key contributor within a squad, taking ownership of technical challenges and elevating the team's output.
• You communicate effectively with technical and commercial stakeholders, translating complex requirements into robust engineering solutions.
