About The Position

Extend is seeking a Technical Account Manager to manage the technical and commercial health of 40-50 mid-market and startup customers. This role requires a technical seller who can build trust with engineering teams, debug integrations, and drive renewals, expansions, and mitigate contractions. The ideal candidate will have sharp commercial instincts, technical fluency with developers, and the ability to manage customer stakeholders and control narratives during challenging situations. Extend is a fast-growing company in the document AI platform space, offering a loved product used in mission-critical flows by major companies. The market for document processing has expanded significantly due to LLMs, and Extend is positioned for substantial growth. This role offers the opportunity for significant impact in a high-performance culture, with high equity ownership and leadership opportunities.

Requirements

Owned commercial outcomes: managed renewals, negotiated, handled objections, and de-risked contractions.
Technical fluency to build trust with engineers: ability to discuss APIs, debugging, and latency, scope issues, and know when to escalate.
Ability to command a room: run meetings with customer engineers and leadership, control the narrative, and move tense conversations forward.
Resourceful and self-directed: experience building own onboarding and systems in a startup environment.
4-6 years of experience in customer success, account management, solutions, or technical support at a developer tools, data/analytics, or AI-native software company.
Ideally 1-2 years at a growth stage startup.

Responsibilities

Own customers' post-sales journey from onboarding, to adoption, to renewal + expansion.
Track usage trends across the customer book, identifying growth and contraction signals to proactively address expansion and churn risks.
Define and implement an early-warning system by identifying key events and actions that indicate account health, expansion potential, or risk, and translate these into reusable reporting and playbooks.
Provide frontline technical support, addressing customer questions, troubleshooting API issues (keys, JSON output, logs) to scope problems, and escalating effectively to support and document engineering teams.
Own customer relationships by running weekly-to-biweekly check-ins with technical stakeholders, understanding their business models and product roadmaps.
Drive renewals, orchestrate expansions, and mitigate contractions across a book of 40-50 accounts, including commercial conversations for contract right-sizing.
