• Design, develop, and support clinical trial software with emphasis on patient safety and integrity of clinical study data • Review product requirements and verify that all requirements can be implemented • Assist with the creation of technical design and implementation documentation • Design and code software applications and fix defects • Provide unit testing coverage for delivered code • Work with others to ensure timely delivery of high-quality code • Manage software deployment into all environments and complete all required documentation • Assist support team with troubleshooting and resolution of production issues • Perform other related duties as required

• Building, shipping, and supporting AI-powered tools and automations for 923 AI Automation clients. • The role sits at the intersection of product thinking and AI engineering — closer to “product manager who builds confidently with modern AI development tools” than “AI research engineer.” • You'll work with tools like Claude Code, the Anthropic API, and AI-augmented low-code platforms to deliver real systems to real clients, end-to-end. • You'll probably enjoy this role if you: - Like framing complex, ambiguous problems and working through them to clear solutions - Enjoy ideating, building, and seeing things ship — then explaining clearly how and why they work - Prefer direct interaction with a mentor over distant management - Want autonomy and trust, not oversight for its own sake - Want to understand why you're building something, not just what to build - Are energised by seeing the whole picture — how a project connects to a client's business, a team's operations, and an emerging practice • You'll probably find this role frustrating if you: - Prefer to work deep in code with minimal client or stakeholder contact — the role sits in the middle of client delivery, not behind it - Are looking for a role with highly structured processes, detailed specifications, and predictable work — this department is actively shaping its own way of working, and the person in this seat will be part of that shaping • This is the intersection of product thinking and AI engineering.
