About the team

We operate at the intersection of platform engineering, developer productivity, and applied AI. As a newly formed squad, we move fast, experiment responsibly, and ship pragmatic, reusable capabilities that fit enterprise standards. You'll help shape our technical direction, culture, and ways of working from the ground up.

What you'll do

• Collaborate on complex technical problems from discovery through implementation, delivering high quality, maintainable solutions.
• Break down requirements into actionable engineering tasks; create clarity for delivery squads and stakeholders.
• Run hands-on experiments with emerging AI/ML and GenAI tooling; design evaluation frameworks, measure outcomes, and provide evidence-based recommendations.
• Build resilient, reusable components, SDKs, and service integrations that slot into pipelines, IDEs, and developer platforms.
• Contribute to architectural discussions; propose improvements and role model engineering standards and best practices.
• Maintain high quality codebases via active code reviews, robust testing, and clear documentation for knowledge sharing.
• Work cross-functionally to align roadmaps, manage dependencies, and land changes with minimal disruption.
• Mentor junior engineers and uplift AI literacy across squads; contribute to communities of practice.

What you bring

• Extensive experience in designing and implementing scalable, maintainable, and reliable software systems.
• Practical knowledge of AI/ML and Generative AI applied to software engineering workflows (e.g., code assist, test generation, knowledge retrieval, anomaly detection), with an understanding of limitations, risks, and safety considerations.
• Proficiency in one or more languages such as Python, TypeScript/Node.js, or C#, and experience building microservices on AWS and/or Azure.
• Architectures: Microservices, event driven patterns, REST/gRPC.
• Cloud: AWS and Azure (e.g., Lambda/Functions, Containers/ECS/AKS, S3/Blob, API Gateway, Step Functions/Logic Apps).
• Data: SQL, data pipelines, observability/telemetry for engineering productivity and quality metrics.
• DevSecOps: GitHub/GitLab/Azure DevOps, Actions/Pipelines, Terraform (IaC), SAST/DAST/SCA, secrets management.
• Strong technical influence: ability to review designs and code, set quality bars, and collaborate with stakeholders to solve business critical problems.
• A growth mindset and bias toward iterative experimentation—from idea to prototype to pilot to product—with clear success metrics.
• Proficiency in agile delivery (Scrum/Kanban) and tooling such as Jira and Confluence.
