Money decisions shape our lives, yet too often people are left without the clarity or tools they need to make informed choices. We exist to change that. Boldin is a comprehensive financial planning platform that helps people understand their financial picture, make smarter decisions with their money and time, and plan for the future with confidence. With over $20M raised and strong momentum, Boldin is entering a pivotal phase of growth. This is an opportunity to join a mission-driven team and help shape the future. ## About This Role Boldin helps people plan for and live a confident retirement. The Time to Value (TTV) team owns the top of the funnel — the experience from a visitor's first touch through registration, onboarding, account linking, trial, and conversion to a paying subscriber. It's where prospective members decide whether Boldin is worth their trust, so the work is equal parts product polish and reliable, integration-heavy engineering. We're hiring a Full Stack Engineer to strengthen this team. Much of the funnel runs on third-party integrations — payment platforms, financial account aggregation, lifecycle messaging, and analytics — and we need someone who is comfortable owning that connective tissue end-to-end, from a React/TypeScript front end through a Ruby on Rails back end to the webhooks that tie external services together. ## Key Responsibilities - Build and maintain the registration, onboarding, checkout, and conversion flows that move visitors to activated, paying members. - Own integrations across the funnel: payment platforms, lifecycle/marketing messaging, and product analytics — including the webhook handlers and gateway services that keep them in sync. - Contribute to the ongoing payments migration (consolidating multiple legacy payment platforms onto our primary processor) and help simplify a multi-gateway billing setup. - Work across the stack: React/TypeScript on the front end, Ruby on Rails on the back end, with the data and webhook plumbing in between. - Partner with product, design, and the broader engineering org to instrument and improve top-of-funnel conversion, grounded in analytics. - Write tested, maintainable code and participate in code review. ## What you'll work on The funnel touches a broad set of external systems. You won't need experience with all of them, but this is the landscape: - Payments & billing: multiple platforms today (primary processor plus legacy gateways and cart/checkout tools), with an active migration to consolidate them. Subscription lifecycle, webhooks, and tax handling. - Financial-account aggregation: linking members' real financial accounts during onboarding — a core, trust-critical part of the product. - Lifecycle & support messaging: in-app messaging/support, marketing automation, and transactional email. - Analytics & experimentation: product analytics and a customer-data pipeline used to measure and improve funnel conversion. KPIS + Targets - Trial Cancels - Subscriber Churn - Stakeholder NPS - Integration cost efficiency ## Qualifications - 4+ years of professional software engineering experience, primarily backend. - Strong experience with a server-side framework and relational database (we use Ruby on Rails; comparable experience is fine if you're eager to pick up Rails). - Strong experience building webhook-driven, third-party API integrations, with sound reasoning about failure, retries, and idempotency. - Working proficiency with a modern JS/TypeScript front-end framework (we use React) — comfortable contributing to the front end when the work calls for it. - A pragmatic eye for the user experience, especially in high-stakes flows like signup and payment. Strong plus - Experience with financial-account aggregation providers (Plaid, Finicity, Yodlee, or similar). - Ruby on Rails experience. - Experience migrating or consolidating payment/billing systems. - Background in fintech, financial services, or another domain with sensitive user data and compliance considerations. - Familiarity with CRM, lifecycle, or analytics tooling (Intercom, ActiveCampaign, Segment, or similar) — these are learnable on the job. - Experience optimizing top-of-funnel conversion and running experiments. ## Our stack - Front end: React, TypeScript, Material-UI, Redux, SWR (Yarn workspaces monorepo) - Back end: Ruby on Rails, PostgreSQL, Sidekiq - Integrations: Stripe, Braintree, ChargeDesk, Plaid, Intercom, Segment, and more - Infra & data: AWS, plus a data pipeline for analytics Salary Range $160,000 - 195,000 DOE We want to be as inclusive as possible in our hiring process.
