Applied AI Engineer - Agentic Workflows in London

Who Are We

Our mission is to scale intelligence to serve humanity. We’re training and deploying frontier models for developers and enterprises that build AI systems to power content generation, semantic search, RAG, and agents. We believe our work is instrumental to the widespread adoption of AI. We obsess over what we build and each of us is responsible for increasing the capabilities of our models and the value they bring to our customers. We work hard and move fast to do what’s best for our customers. Cohere is a team of researchers, engineers, designers, and more who are passionate about their craft. Each person is one of the best in the world at what they do, and diversity of perspectives is a requirement for building great products.

Why This Role

We are a fast‑growing startup building production‑grade AI agents for enterprise customers at scale. We’re looking for Software Engineers with applied AI experience who can own the design, build, and deployment of agentic workflows powered by LLMs—from early prototypes to production‑grade AI agents—to deliver concrete business value in enterprise workflows. In this role, you’ll work closely with customers on real‑world business problems, often building first‑of‑their‑kind agent workflows that integrate LLMs with tools, APIs, and data sources. While our pace is startup‑fast, the bar is enterprise‑high; agents must be reliable, observable, safe, and auditable from day one. You’ll collaborate closely with customers, product, and platform teams, and help shape how agentic systems are built, evaluated, and deployed at scale.

What You’ll Do

• Work closely with enterprise customers to translate high‑value, ambiguous business problems into well‑framed agentic problems with clear success criteria and evaluation methodologies.
• Provide technical leadership across the full development and evaluation lifecycle, including post‑deployment iteration, for agentic workflows.
• Contribute to shared frameworks and patterns that enable consistent delivery across customers.
• Lead the design, build, and delivery of LLM‑powered agents that reason, plan, and act across tools and data sources with enterprise‑grade reliability and performance.
• Balance rapid iteration with enterprise requirements, evolving prototypes into stable, reusable solutions.
• Define and apply evaluation and quality standards to measure success, failures, and regressions.
• Debug real‑world agent behavior and systematically improve prompts, workflows, tools, and guardrails.
• Mentor engineers across distributed teams.
• Drive clarity in ambiguous situations, build alignment, and raise engineering quality across the organization.

Required Skills & Experience

• Production engineering: substantial experience building, shipping, and maintaining production‑grade software (Python/TypeScript).
• Ability to write clean, testable, observable and scalable code.
• Agentic architectures: hands‑on experience building agents that plan and execute multi‑step tasks (e.g., ReAct, Plan‑and‑Execute) and interact with external APIs/tools.
• The LLM stack: deep familiarity with frontier models (GPT, Claude, Gemini), RAG, vector databases (Pinecone, Weaviate, etc.), and orchestration frameworks (LangGraph, CrewAI, or custom state machines).
• Rigorous evaluation: proven ability to build robust evaluation frameworks to measure agent accuracy, safety, and latency.
• Stakeholder mastery: experience leading technical discussions with enterprise customers to translate ambiguous business needs into concrete technical specs.
• Leadership: experience mentoring distributed teams and setting architectural standards for AI/agentic systems.

Additional Requirements

• Strong written and verbal communication skills.
• Ability and interest to travel up to 25%, flexible.

Why Join Us

• Build production‑grade AI agents used in real enterprise workflows.
• Operate at scale while retaining end‑to‑end ownership.
• Work on hard problems in agent design, evaluation, and reliability.
• Shape shared platforms and standards, not just individual features.
• Move fast with a high bar for quality, safety, and reliability.

Diversity & Inclusion

We value and celebrate diversity and strive to create an inclusive work environment for all. We welcome applicants from all backgrounds and are committed to providing equal opportunities.
