We are partnering with a rapidly growing, VC-backed AI Software Factory that is modernizing the world’s most critical physical industries. While much of the tech world focuses on social apps, this company is tackling the "societal problem" of inefficient legacy systems in energy, logistics, and manufacturing.

What makes this role unique is the "AI-first" development philosophy. You won't just be writing boilerplate code; you will be leveraging advanced AI workflows to scaffold and automate routine tasks, allowing you to focus on high-level architecture and complex integration challenges. It’s a chance to be at the forefront of how software engineering is evolving.

You will lead the implementation and delivery of backend services, integrations, and workflow logic that power the companies SaaS applications. Rather than reinventing the wheel, you'll leverage an existing AI-Software Factory platform to build robust, scalable tools for customers. This team is pioneering a new way of working where the engineer will use advanced AI workflows to accelerate routine development, allowing you to focus on high-value problem-solving, validating automated outputs, and solving complex integration challenges.

• Build and own core backend features and critical API integrations (Python, FastAPI, SQL).
• Design and implement complex data pipelines and workflows using tools like Dagster and Temporal.
• Validate and harden accelerated workflows, ensuring generated code meets production standards.
• Implement resilient connectors for APIs, file systems, and enterprise platforms.

• Champion the use of AI-assisted tools to plan, scaffold, and refactor code efficiently.
• Collaborate with Solution Strategists and Platform teams to ship value to customers faster.

• Familiarity with (or keen interest in) agentic AI coding tools (e.g., Cursor/Codex/Claude Code) to plan, scaffold, refactor, and test.

• Workflow orchestration and data engineering experience (e.g. Temporal, Dagster) know-how.
• Familiarity with CI/CD, Docker, cloud (Azure/AWS/GCP).
• Interest in AI and raising team AI skills.
