Staff Software Engineer, GTM AI Engineering

About Anthropic

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

About the role

As a Staff Software Engineer on the GTM AI Engineering (Claudification) team, you will build the agents and AI systems that run Anthropic's own go-to-market work. Our sellers already work alongside agents every day. You will take things to the next step and build agents that run complete autonomous motions across areas like inbound, outbound, and pipeline management. In addition, you’ll build eval frameworks that prove those agents are ready for customer-facing work and are driving value. This is a senior role where you’ll drive technical direction for agents and evals across our team.

Working closely with sellers, RevOps, and our platform engineering partners, you'll own projects from first prototype through production operation. You'll combine full-stack engineering (MCP servers, agentic systems, web applications, etc.) with hands-on evaluation work (behavior benchmarks, production monitoring, ROI measurement), and help architect the shared platforms that builders from across our go-to-market org contribute to. You've worked in cultures of analytical rigor before, and you're eager to help shape the norms and best practices of a growing AI engineering function at a pivotal moment in the company's growth.

Key responsibilities

Build and operate autonomous agents that run go-to-market motions end to end, across areas like inbound, outbound, pipeline management, and customer engagement

Design the human oversight for each motion: approval gates, handoffs, and escalation paths that keep sellers in control

Develop evaluation frameworks for agent behavior, and run them in development and in production

Instrument model and tool calls in production, and build the observability and measurement that ties agent actions to pipeline and revenue

Ship MCP servers, agent skills, and web applications that connect to systems like our CRM, communication tools, and data warehouse

Set the technical direction for how we build, evaluate, and operate agents across the team

Architect shared codebases that builders from across go-to-market contribute to, setting the conventions and review practices that keep quality high

Work directly with sellers to ground agent designs in real workflows, and iterate based on what you observe

Identify repeatable patterns and contribute insights back to Anthropic's Product and Engineering teams

Maintain strong knowledge of the latest developments in LLM capabilities, agent frameworks, and evaluation techniques

Minimum qualifications

Strong programming skills in Python or TypeScript, with experience building and operating production applications

Production experience with LLMs, including context engineering, agent development, MCP development, tool use, and evaluation frameworks

Experience using evals and transcript analysis to find and fix real problems in an LLM system

Working fluency with data, including SQL

Ability to navigate ambiguity and ship without a spec, finding simple solutions to complex problems

Passion for advancing safe, beneficial AI, and care for the people who use what you build

Preferred qualifications

8+ years in roles such as software engineer, ML engineer, or forward deployed engineer. Former technical founders are encouraged to apply

Experience with the Claude Code and the Claude Agent SDK

Experience with go-to-market systems (CRM, sales engagement, enrichment, conversation intelligence) or time working closely with a revenue team

Experience growing a codebase that many people contribute to, inner-source or open-source

Applied ML and experimentation background: A/B testing, propensity models, recommendations, or causal analysis

Exceptional communication skills to convey technical concepts to non-technical partners with low ego

Representative projects

(Illustrative of the kind of work, not a project list.)

Build an agent that takes a routine sales workflow from first signal to a drafted, human-reviewed action

Stand up the eval suite for an agent: seed scenarios, scoring rubrics, and regression runs on every change

Ship an MCP server that gives sellers and their agents governed access to a core revenue system

Design a shared repository where go-to-market builders publish agents and skills, with the tests and review rules that keep it healthy

Build a predictive model that explains itself, so an agent can tell a seller why it suggests an action

The annual compensation range for this role is listed below.

For sales roles, the range provided is the role’s On Target Earnings ("OTE") range, meaning that the range includes both the sales commissions/sales bonuses target and annual base salary for the role.
