You'll work alongside 1,300+ teammates from 40+ nationalities and tackle global challenges from day one. What Will I Be Doing? Technical Leadership of Initiatives • Act as the technical lead of AI initiatives, from the first definition of the problem through delivery in production, working alongside the engineers and team leads who execute them. • Work directly with peers and business stakeholders to understand needs, agree on scope and priorities, and keep expectations aligned as the work evolves. • Translate business goals into technical plans, milestones and trade-offs, and raise risks early. • Make sure initiatives reach production with outcomes that can be measured and explained to the business. Architecture & Technical Direction • Lead the design and architecture of AI systems, including agentic workflows, retrieval, tool use, orchestration and state management, built by one or several teams. • Define reference architectures, patterns and engineering standards that other teams adopt and reuse. • Make and document trade-off decisions across quality, latency, cost, security and vendor dependency. • Solve the most complex technical problems in your area and unblock the teams around you. Quality & Evaluation of AI Systems • Establish how AI behavior is measured: evaluation datasets, regression tracking, quality metrics and acceptance criteria for agents and LLM-based features. • Ensure systems are tested against realistic cases, not only demos, before and after they reach production. • Define the telemetry needed to understand cost, latency, quality and outcomes end to end. Production Excellence • Lead operational practices: reliability, scalability, resilience, observability and incident learning for AI services. • Examine production behavior, identify structural improvements and drive them to completion with the owning teams. • Keep cost under control through routing, caching, context management and capacity decisions. Security, Governance & Compliance by Design • Design controlled access for agents that act on internal systems: permissions, guardrails, audit trails and human-in-the-loop checkpoints. • Work with Security, Legal, Compliance and IT so that governance requirements are built into reusable components and not rebuilt for every use case. Multiplying Impact • Mentor engineers and tech leads, and raise the technical level of the teams you work with. • Turn what you learn into playbooks, templates, shared libraries and documentation that others can use without you. • Communicate clearly with technical and non-technical stakeholders, and align teams around shared standards. • Share knowledge through internal write-ups and tech talks, and occasionally through external meetups and conferences. What Skills Do I Need? Technical depth • 8+ years of software engineering experience, including significant experience operating at senior or Staff-level scope. • 2+ years of hands-on experience building and operating systems based on LLMs, ideally in production. • Experience designing agentic or multi-step AI systems involving tool use, orchestration, state, retrieval or external integrations. • Strong foundations in distributed systems, including synchronous and asynchronous communication, and in software architecture principles and practices. • Solid knowledge of cloud infrastructure, preferably AWS, and of running services securely and cost-consciously. • Experience with observability, testing and evaluation of complex systems. Technical leadership • Track record of technically leading initiatives that involve multiple teams, from design to production. • Comfortable working directly with business stakeholders and engineering peers to agree on scope, priorities and outcomes. • Ability to understand trade-offs, make decisions with incomplete information and stay effective in crisis situations. • Experience defining engineering standards and best practices that teams actually adopt. • Able to influence without authority, and to explain technical decisions to non-specialists in concrete, concise terms. Nice to have • Experience with agent frameworks and protocols such as LangChain, LangGraph, the Claude Agent SDK or MCP. • Experience with Kubernetes and containerized execution environments. • Experience with LLM gateways, model routing and cost management. • Background in machine learning or applied research. • Experience in regulated environments such as payments or financial services. Mindset • Builder attitude: you prefer reusable platforms and tools over one-off solutions. • Curious and biased toward experimentation, combined with disciplined measurement and risk awareness. • Comfortable with ambiguity in a fast-moving field, and able to structure your own work and keep stakeholders informed.
