• Own features end-to-end, from technical design through implementation, testing, deployment, monitoring, and iteration
• Contribute to architectural decisions, code reviews, and reliability improvements that raise the bar for the broader team
• Analyse system performance and user behaviour to identify opportunities for automation, optimisation, and cost reduction

• Strong command of both modern frontend and backend development, with the ability to contribute meaningfully across the full stack
• Hands-on experience designing and maintaining RESTful APIs, microservices, or event-driven systems
• Comfort with data storage and cloud infrastructure at a senior level — you know how to make the right tradeoffs without needing to be told
• A product engineer mindset: you think about the user experience, ask why before how, and take ownership of outcomes, not just outputs
• Strong communication skills and a track record of effective cross-functional collaboration with distributed teams
• Experience with conversational AI, LLM orchestration, or automation systems
• Experience building customer service, CRM, telephony, contact center, or workflow automation tools
