Senior Software Engineer - Frontend, Fintech
POS-15631
Hubspot Engineering
We ship customer-centered, autonomous product teams that take features from idea to production and support them in production. We care about building reliable, maintainable systems and a culture of learning and inclusion.
About the team
The A&B team owns the central customer-facing hub for subscription and billing management, powering over $3 billion in annual recurring revenue. While many teams touch billing, A&B is responsible for making Account & Billing the single destination where customers understand what they have, manage their subscription, and take action.
The team balances two roles: stewarding the A&B surface area with clear ownership of tabs, components, and workflows, and coordinating cross-team initiatives that eliminate friction across the broader billing journey. This includes driving comprehension of usage and billing, enabling self-service modifications within policy bounds, and providing seamless paths to upgrade.
Why this role matters
A successful Senior Software Engineer on the Account & Billing Experience team will make it easy for customers to understand bills and usage, reduce support dependency by expanding self-service coverage, and lead cross-functional programs that simplify complex subscription journeys. You’ll work end-to-end with collaboration from backend and product partners.
What you’ll do
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.
What we’re looking for
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.
Nice-to-haves
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.
What success looks like after 6–12 months
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.
