Staff Software Engineer, Internal Products

Anthropic•Seattle, WA

1d•$405,000 - $485,000•Hybrid

About The Position

Anthropic is hiring a Staff+ full-stack engineer to build internal products used by sales teams and the teams supporting them. The work spans the seller-facing products and AI agents that assist with sales workflows, including managing accounts, pricing and approving deals, preparing renewals, and handing closed deals off for billing and provisioning. The role is a greenfield opportunity to shape the underlying systems and determine how agents and sellers get the context they need to make high-quality deals. The engineer will work directly with sellers, deal desk, finance, and legal, balancing speed with correctness because mistakes can flow through to billing and revenue. They will set technical direction across a domain, lead engineers through large and ambiguous projects, and own the reliability of the workflows they ship, including on-call responsibilities.

Requirements

Production experience as a backend-leaning full-stack engineer, including comfort designing data models, APIs, and user interfaces.
Experience building software on LLMs or agents and a considered approach to when an agent should act independently versus ask for confirmation.
Experience leading the design and delivery of complex, user-facing full-stack products while requirements change.
Experience designing for correctness and data integrity from the outset, and building systems that are easy to reason about when money is involved.
Experience working across functions and translating between sales, finance, legal, and engineering to reach decisions.
Bachelor’s degree or an equivalent combination of education, training, and/or experience.
A field of study relevant to the role, demonstrated through coursework, training, or professional experience.

Nice To Haves

Experience building internal products or workflow tools for sellers or their supporting teams.
Experience taking an agent into production for a high-stakes workflow, including the evaluations and guardrails needed to ship it safely.
Experience building a zero-to-one product or rebuilding a product that people already depend on every day.
Experience building pricing, billing, or payments systems and understanding how pricing changes affect downstream systems.

Responsibilities

Design and ship internal products end to end, from data models and APIs to user interfaces, for seller planning, deal approvals, renewals, and handoffs to billing and provisioning.
Build and apply Claude agents to sales tasks such as preparing renewals, gathering deal context, and updating account details; determine when an agent or a user interface is the right approach.
Make agents safe to use in deal workflows through scoped access to customer and deal data, guardrails, evaluations, audit trails, and human confirmation points.
Build shared capabilities, exposed as APIs and MCP tools, that people and agents can both use for tasks such as pricing deals, requesting approvals, and handing off closed deals.
Work with sellers and support teams to identify and remove workflow friction, treating speed and polish as product requirements.
Design for correctness in downstream revenue, billing, and account workflows, applying idempotency, reconciliation, and audit trails where appropriate.
Integrate with third-party systems used by sellers and support teams, and build a layer on top of them for people and agents to do their work.
Set technical direction for a domain over multiple quarters, lead engineers across teams on large and ambiguous projects, and raise engineering standards.
Operate shipped products, own workflow reliability, and participate in on-call support.
