🚀 Real Ownership – Engineers shape product and AI architecture decisions, not just tickets.
🌍 Meaningful Scale – Your models and code impact thousands of global businesses.
🧠 AI-First Engineering Culture – We value thoughtful system design, rigorous evaluation, and pragmatic AI solutions over hype.
🤝 Collaborative Teams – Work closely with Product, Design, and Data in empowered squads.
📈 Room to Grow – Expand your scope, influence AI architecture, and mentor others.

Our tech ecosystem is rich, complex, and constantly evolving as we expand our AI capabilities and ship new intelligent features. You'll be part of a team that values curiosity, healthy debate, and continuous improvement — always with the customer at the centre of what we build.

The Role

As a Senior AI Software Engineer, you'll play a key role in launching and scaling a new AI-native product area. You'll work in a cross-functional squad to:

• Turn ambiguous problems into well-designed, scalable AI-powered systems
• Build high-quality, LLM-driven features end-to-end — from prototype to production
• Design and integrate agentic workflows, retrieval systems, and model-orchestration pipelines
• Deliver AI solutions that make a measurable difference for customers

You'll contribute across the stack, with a strong focus on backend APIs and services that power AI/LLM-driven functionality in expenses and procurement.

Our Current Stack

• React Node.js
• JavaScript & TypeScript
• LLM APIs (OpenAI/Anthropic/similar)
• Vector databases & retrieval pipelines

That said, our interview process is technology-agnostic. We care more about strong engineering fundamentals, applied AI/ML judgment, and a learning mindset than specific framework experience.

What You'll Be Doing

• Design, build, and ship end-to-end AI-powered features for a new product
• Collaborate closely with Product Managers and Designers to shape technical and AI strategy
• Develop and evolve scalable backend APIs, microservices, and LLM-orchestration layers
• Build robust evaluation frameworks to test and improve model performance and reliability
• Write clean, well-tested, maintainable code — including around probabilistic/AI components
• Participate in code reviews, architecture discussions, and pair programming
• Mentor junior engineers and help raise engineering and AI-quality standards
• Contribute to a team culture of continuous learning and shared success

About You

You might be a great fit if:

• You take pride in building reliable, high-quality AI-powered software
• You think in systems and care about long-term maintainability — including of AI/LLM pipelines
• You've built or shipped features using LLMs, agents, embeddings, or similar AI tooling
• You enjoy collaborating and shaping ideas early, especially where the "right approach" isn't obvious yet
• You're comfortable mentoring others and sharing knowledge
• You thrive in environments where you have ownership and influence
• You're adaptable and excited to learn new AI techniques, models, and domains
