Requirements

We are seeking top 1% engineering talent – highly analytical developers with strong educational and professional pedigrees.
Essential:
• Minimum 2 years’ experience as a professional software engineer working on production-grade systems with real-world users
• High fluency in Python and TypeScript – comfortable with async operations, error handling, and performance tuning
• Strong problem-solving and troubleshooting skills across complex tech stacks
• Computer Science or Mathematics degree from a top-tier university
• Clear, consistent work history – no more than one move every 2.5–3 years
• Background at elite tech firms (e.g., Google, Meta, Amazon, Netflix, Microsoft, or quantitative finance competitors)
• Curiosity and insight into how AI agents behave, learn, and fail – with a strong desire to improve their intelligence and reliability
Nice-to-have:
• Experience building voice interfaces or multimodal AI systems
• Familiarity with enterprise customer experience platforms or conversational automation tools
• Interest in developing visualisation and simulation tools to increase AI agent transparency

Role & Responsibilities

As an AI Agent Software Engineer, you will design and build high-performance AI agents that deliver customer experiences more accurate, efficient, and satisfying than their human counterparts.
You will work in a highly collaborative, engineer-led environment with full-cycle ownership – from idea to production deployment – and have a direct impact on how enterprise clients engage with their users.
Your work will involve:
• Designing and building AI agents that operate across chat and voice, executing complex tasks with precision
• Translating natural language into structured, software-grade agent logic
• Analysing agent performance at scale to uncover trends and opportunities for platform improvement
• Experimenting with the latest language and voice model advancements, tuning them for reliability and performance
• Using real-time observability tools (e.g. Trace View) to audit and improve agent decision-making with transparency
You’ll collaborate with product managers, customer-facing teams, and fellow engineers to shape agent behaviour, improve outcomes, and solve real-world problems across sectors such as finance, healthcare, and travel.

Why This Role?
This is not a legacy code maintenance role. It is a greenfield opportunity to redefine how millions interact with technology through AI.
You’ll join a team that values:
• Transparent, testable AI behaviour – no monolithic prompts, no guesswork
• Modular, auditable agent logic – easy to version, debug, and improve
• A fast feedback loop – engineers work closely with customer teams to rapidly prototype and deploy improvements
You will help companies cut support costs, raise satisfaction scores, and scale customer support without growing headcount.

• Flexible PTO – take what you need
• Lunch and snacks provided daily
• Strong engineering culture focused on iteration, transparency, and technical excellence
