Senior Software Engineer, New Verticals

You’ll also build the agentic systems our salons and teams use: agents that reason, retrieve information, call tools and execute controlled workflows across bookings, payments and operations.

You’ll work closely with product, operations, salon partners and booking-platform partners to turn frictionless payments into real growth for beauty businesses. If you thrive in a fast-moving, build-from-scratch environment and you already work this way, this role is for you.

What you’ll own

• Direct AI agents to design, build and operate secure, reliable payment services for salons: checkout, booking deposits and no-show fees, tips and tip splitting across staff, refunds, reconciliation and settlement
• Own integrations with salon management and booking platforms, payment providers, financial partners and other third-party systems, specified and delivered through agents
• Write the specs, acceptance criteria, test suites and evals that define “done”, so agent output is verified by evidence rather than by reading the code
• Design and run the agentic development workflow itself: which agents do what, how they’re prompted and given context, and how their work is checked, merged and deployed
• Build AI-powered and agentic products for salons and internal teams, such as agents that answer client questions, manage booking and payment exceptions, or handle reconciliation, using retrieval, tool calling and controlled actions
• Put permissions, human approvals, guardrails, observability, audit trails and fallbacks around every agent that can touch money, client data or a salon’s calendar
• Find and fix bottlenecks in speed, reliability, security and cost, including LLM and agent cost, * Real ownership over products that impact millions of diners and thousands of restaurants globally
• The opportunity to solve challenging problems in payments, hospitality, and customer experience
• A fast-moving environment where great ideas quickly become reality
• Close collaboration with experienced operators, builders, and industry experts
• A chance to leave a visible mark on one of the fastest-growing restaurant technology companies globally

• You’ve shipped production software in a fast-moving, high-growth environment
• You move fast and make strong decisions with incomplete information
• You take real ownership and think like an operator, not a coordinator
• You’re energised by hard problems in payments, beauty and wellness, and client experience
• You trust evidence over output: if it isn’t tested, measured and observable, it isn’t done

What you’ll need

• Proven experience shipping production-grade software, with a track record of doing it through AI coding agents
• Fluency in English is a must
• Excellent problem-solving and communication skills
• Hands-on experience with LLM APIs, tool calling, retrieval-augmented generation and agentic workflows in production
• Strong grasp of system design: REST APIs, microservices, asynchronous processing and distributed systems
• Solid knowledge of databases, data modelling and database design
• Experience with payment providers, booking or POS systems, or complex third-party integrations
• A clear understanding of AI-system risks: hallucinations, prompt injection, data leakage, non-deterministic behaviour and unsafe tool execution, and how to contain them
• Experience with automated testing, evals, observability, debugging and performance optimisation

Nice to have

• Experience in payments, fintech, beauty and wellness tech, booking platforms or a high-growth marketplace
• Experience with payment gateways, transaction processing, settlement, reconciliation, or chargeback systems
• Experience building agents that operate on APIs, databases, internal tools or operational workflows
• Familiarity with model evaluation, prompt and context management, AI observability, guardrails or LLM cost optimisation
• Experience running multiple coding agents in parallel, or building the tooling and CI that keeps them safe
• Exposure to vector databases, embeddings, semantic search or retrieval systems
• Experience with cloud platforms, containerised services, CI/CD and infrastructure-as-code
• Familiarity with PCI DSS, GDPR and secure development practices
