[Hiring] Senior Software Engineer, Frontend, Fintech @HubSpot

Role Description

This role involves working on the Account & Billing Experience team to enhance customer understanding of billing and usage, reduce support dependency, and lead cross-functional programs.

• Own major frontend surface areas in the Account & Billing hub - tabs, components, and end-to-end workflows - delivering high-quality, reliable, and accessible experiences.
• Align product, design, backend, and go-to-market partners to solve end-to-end customer problems.
• Ship scalable, maintainable TypeScript + React code, with attention to performance, observability, testing, and UX edge cases.
• Translate customer pain points and data into concrete product improvements that reduce friction (e.g., seat management, delta billing, marketing contacts limits).
• Expand self-service capabilities so more billing actions are available without human intervention, while ensuring changes stay within policy bounds.
• Mentor and raise the bar for other engineers on the team through code reviews, pairing, and shared technical ownership.
• Contribute to frontend architecture and the team’s design system/components; scope and deliver safely for enterprise and SMB customers.
• Measure outcomes and iterate: work with PM and analytics to set success metrics, instrument features, and act on feedback.

Qualifications

• Strong frontend experience (typically 5+ years) building production web applications with TypeScript and React.
• Deep product and UX sensibility: you can reason about user flows, edge cases, and how design decisions impact customer comprehension.
• Experience delivering end-to-end features and owning surface areas (components, pages, instrumentation, and rollout).
• Proven ability to lead cross-team efforts and influence without formal authority.
• Solid engineering fundamentals: testing, performance optimization, accessibility, observability, and CI/CD.
• Excellent collaboration and communication skills — you’ll work closely with PMs, designers, backend engineers, customer-facing teams, and stakeholders.
• Comfortable working in a fast-moving environment and mentoring less-experienced engineers.

Requirements

• Prior experience with billing, subscriptions, payments, or Fintech products.
• Experience with GraphQL/REST at scale, complex client-side state management (Redux/MobX/relay), and component design systems.
• History of improving CSAT or operational metrics through product/engineering work.
• Familiarity with enterprise purchasing and seat management patterns.
• Knowledge of privacy/security considerations for billing/financial data.

Benefits

• You own and reliably deliver improvements to one or more A&B surface areas (tabs/components/workflows).
• Measurable increases in self-service coverage for targeted billing actions.
• Clear wins on Billing CSAT priorities and demonstrated cross-team leadership on at least one major initiative.
