• Partner with business stakeholders to understand workflows, identify bottlenecks, and prioritise engineering opportunities.
• Build and maintain integrations with CRM, marketing automation, analytics, and other business systems.
• Develop and maintain web-based applications and website infrastructure that support Marketing and Growth initiatives.
• Use LLM APIs, AI coding assistants, and agent-based development workflows to accelerate engineering productivity.
• Ensure solutions are maintainable, reliable, secure, and suitable for production use.
• Measure tool adoption, operational efficiency, and business outcomes, iterating based on stakeholder feedback.

• Strong professional software engineering experience, ideally involving full-stack development, internal tools, automation, or growth engineering.
• Hands-on experience with JavaScript or TypeScript and modern web frameworks such as React or Next.js.
• Strong experience working with APIs, system integrations, and data-driven applications.
• Practical experience building AI-powered applications, agents, or automations using LLM APIs.
• Experience taking applications from prototype to production, including testing, deployment, maintenance, and troubleshooting.
• Ability to understand business problems and independently translate requirements into working technical solutions.
• Strong ownership, problem-solving, and cross-functional collaboration skills.
• Strong English communication skills and the ability to work with technical and nontechnical stakeholders.

• Experience integrating Salesforce, marketing automation, or revenue operations platforms.
• Familiarity with AI coding assistants such as Claude Code or Cursor.
• Experience maintaining CMS-driven websites or marketing technology.
• Familiarity with developer-focused SaaS products, API platforms, or agent-based workflows.
• Experience developing reusable internal AI tools or agent skills.
