Salary: $140K – $180K + equity

Location: Palo Alto, CA or New York, NY (5 days in-office, relocation assistance available) | Visa sponsorship available

Company Description: Series A fintech infrastructure startup, $45M raised, rebuilding the $13T mortgage industry

Job Description: Join a 40-person team that is rebuilding America’s mortgage infrastructure from the ground up. Mortgage origination costs have doubled to $12K per loan. This company’s autonomous infrastructure cuts that cost by 74% and helps clients make 102bps more per loan. Leading fintechs, lenders, and publicly traded banks are already building and scaling their originations on top of the platform. Backed by $45M from top-tier fintech and institutional investors alongside founders of some of the most respected companies built in the last decade. This is the first TAM hire at the company. There is no one in this role today. You will define what great technical account management looks like here and very likely end up leading the entire function as it grows.

Why this role is remarkable:

• Be the first Technical Account Manager at a well-backed fintech infrastructure company with real customers including publicly traded banks already building on the platform, meaning the problems you solve are production-grade and high-stakes from day one
• Define and build the entire TAM function from scratch, creating the playbooks, processes, and standards for how a category-defining mortgage infrastructure company supports and scales enterprise client integrations
• Work at the intersection of deep technical work and senior client relationships at a company where the API is the product, giving you visibility and influence across engineering, product, and growth in a way that almost no TAM role at this stage ever offers

What you will do:

• Own client integrations end-to-end from onboarding through production stability, guiding enterprise customers through API integration across the full platform and diagnosing and resolving complex issues using observability tools like Sentry, Honeycomb, and Datadog with real root cause analysis
• Build and scale the integration and onboarding processes from scratch, creating documentation and tooling that allows clients to successfully build on the platform and unlocking new value as the customer base grows
• Work directly with product and engineering to escalate incidents and translate client needs into product improvements, serving as the connective tissue between what customers need and what the team builds next

The ideal candidate:

• 3 or more years of experience in a technical customer-facing role like TAM, solutions engineer, or FDE at a B2B fintech or API-first technology company, with hands-on API debugging expertise across JSON responses, request tracing, and log analysis, and a degree from a top-30 program
• Track record of owning post-sales client lifecycle end-to-end, managing enterprise or publicly traded client accounts, and building or scaling integration and onboarding processes from scratch in a fast-paced startup environment
• Career progression that shows consistent growth in technical scope and seniority, not just relationship management, and genuine excitement about being first in a function and defining what it looks like rather than inheriting someone else’s playbook

Next steps:

• Apply via this LinkedIn job post
• We will review and reach out if there is a strong match
• If aligned, we will introduce you directly to the team
• If this role is not the right fit, we may suggest and make introductions to other high-signal startup roles we are actively recruiting for, always with your permission

A quick note on authenticity: This is a real, active role we are supporting in close partnership with the hiring team. We do not post speculative roles and work closely with teams on their actual hiring needs.
