Requirements
  • Seven or more years delivering production software with measurable business outcomes in a product-driven company; experience in a high-growth SaaS or scale-up environment strongly preferred
  • Demonstrated ability to operate at senior individual contributor level without dedicated product managers or designers — independently defines scope, navigates ambiguity, makes architecture trade-offs, and owns delivery and outcomes end-to-end
  • Hands-on experience building integrations against enterprise SaaS APIs across HR, Finance, or IT platforms (Workday, Microsoft 365, Atlassian, or equivalent), including workflow automation, event-driven logic, and document processing
  • Fluency with large language model APIs and production AI workflows: demonstrated experience shipping agents, document processing pipelines, Q&A systems, or AI-assisted automation in a real operational context, not prototypes
  • Track record of leading complex, cross-functional automation initiatives with direct operational impact; prior experience working closely with Finance, HR, or IT functions is a meaningful advantage
  • Active practitioner of modern AI development tools including Claude, Lovable, Cursor, or equivalent; familiarity with agent frameworks, managed container platform integrations, RAG pipelines, and workflow automation tooling
  • Ability to think at systems level: understands how internal processes connect across the business, the compliance and security implications of automation in sensitive functions, and designs tooling that is robust, auditable, and safe
  • Familiarity with compliance and governance requirements (PCI DSS, SOC2, ISO27001, GDPR, or equivalent) as they apply to automated systems handling financial, HR, or identity data is a strong plus
  • Clear, direct communicator: translates operational problems into technical requirements and explains technical decisions to non-technical stakeholders and senior leadership with equal confidence
Responsibilities
  • Own end-to-end delivery of AI and automation initiatives across Finance, HR, IT, Legal, and Operations, from stakeholder problem definition and scoping through production release and measurable impact, operating without dedicated product management or design support
  • Identify, prioritise, and build the highest-leverage automation opportunities across internal functions: examples include financial close automation, employee self-service workflows, IT access provisioning and offboarding pipelines, contract review assistance, and policy Q&A agents
  • Design and ship AI-powered systems that replace manual internal processes, including document processing pipelines, approval automation, data extraction and reporting, HR workflow orchestration, and compliance evidence collection for SOC2, ISO and similar frameworks
  • Engage directly with functional leaders (Finance, HR, IT, Legal) and their operational teams to identify build priorities, translate operational pain into technical scope, and maintain alignment on delivery cadence and outcome metrics
  • Build rapidly and iterate based on real feedback: prototype in days, ship to production in weeks, and establish a pattern of continuous improvement rather than polished one-time releases
  • Make pragmatic use of AI development tools, LLM APIs (Claude, OpenAI), and cloud-native integrations, solving problems at scale without reinventing infrastructure that already exists across the Microsoft 365, Workday, and Atlassian ecosystems
  • Establish reusable patterns, services, and frameworks that give internal functions self-serve automation capability and reduce future build time on adjacent problems
  • Set technical direction for internal AI tooling, make and document architecture decisions, and champion AI-native practices through code review, pairing, and direct coaching of engineers and operations staff who want to build more effectively
  • Define and communicate technical decisions in clear, non-technical terms to leadership and cross-functional stakeholders, maintaining alignment and influencing investment priorities across the business
Desired Qualifications

  • Demonstrated ability to operate at senior IC level without dedicated product managers or designers — independently defines scope, navigates ambiguity, makes architecture trade-offs, and owns delivery and outcomes end-to-end
  • Hands-on experience building integrations against enterprise SaaS APIs across HR, Finance, or IT platforms (Workday, Microsoft 365, Atlassian, or equivalent), including workflow automation, event-driven logic, and document processing

  • Active practitioner of modern AI development tools including Claude, Lovable, Cursor, or equivalent; familiarity with agent frameworks, MCP integrations, RAG pipelines, and workflow automation tooling
  • Ability to think at systems level: understands how internal processes connect across the business, the compliance and security implications of automation in sensitive functions, and designs tooling that is robust, auditable, and safe

Mews raises $300M at $2.5B valuation to build AI agents for autonomous hotel operations

Mews, an Amsterdam-based hotel technology company, has raised $300 million to develop AI agents capable of autonomously managing hotel operations. The round values the company at $2.5 billion, roughly double its $1.2 billion valuation from March 2024. The funding will support development of agentic AI software that coordinates pricing, staffing and guest services across hotel systems without manual intervention. The approach requires hotels to transition from legacy systems that cannot support such automation levels. Mews' vision depends on hotels shifting operational decision-making to algorithms, though the company has yet to demonstrate this capability at scale. The technology aims to create an operating system that fundamentally changes hotel management processes.
