Senior Web Applications Engineer / Typescript / Node.js / React

Seeking a Senior level Web Applications Software Engineer with strong experience in Typescript, Node.js, and React who is skilled in owning products end-to-end. This group owns the borrower experience from the first landing page through the application funnel. That includes the intake flow, offer-code entry, and refinance pre-qualification. The work directly impacts conversion, revenue, and whether someone gets the loan they came for.
The team is heavily frontend focused and driven by experimentation. You'd work within a shared design system, run A/B tests, and use analytics to understand how users move through the funnel. That includes conversion tracking, form-step instrumentation, session insights, and frontend error monitoring. Performance and stability matter because this is the front door to the business, and any friction in the funnel has a measurable impact.
You will be a good fit if you think about product and engineering together, care about outcomes instead of just shipping features, and enjoy moving quickly, testing ideas, and learning from real user behavior in short feedback cycles.
As a Senior Software Engineer, you will be working on an innovative and scalable platform that originates personal loans. You will use your experience in software development to write clean, tested, and well-documented code, as well as provide peer code review and mentor other engineers on the team.
About the Role
You will own meaningful product and technical initiatives end to end.

• Taking ideas from problem statements to shipped, measurable outcomes
• Working directly with product and business partners to make tradeoffs that actually matter
• Measuring success by impact: conversion, adoption, reliability, and real user outcomes

You will lead by example:

• Set engineering standards and patterns through your work, not documents
• Raise the bar on quality, pragmatism, and speed
• Bring depth when things get complex and simplicity when they don't need to be

You will constantly look for leverage:

• Improve conversion and product experience, not just "code correctness"
• Introduce or evolve technology when it creates real value.
• Identify small, incremental improvements that compound over time

What You Need

• Product Mindset: You start with the user and the business problem, not the solution. You understand what the end user is trying to accomplish, why it matters, and how success is measured before writing a line of code.
• End-to-end Ownership: If you build it, you stay connected to it from design and implementation through deployment, monitoring, fixes, and future improvements.
• Pragmatic Approach: You value simple, durable solutions over clever ones. You know when to invest in long-term architecture and when to optimize for speed and learning.
• Bias toward Action: You don't wait for perfect requirements or complete clarity. You break complex problems into smaller steps, ship incrementally, learn from real usage, and adjust quickly.
• Clear, direct communication: You explain decisions, tradeoffs, and impact clearly to engineers, product partners, and business stakeholders. You contribute through demos, discussions, and collaboration, not just pull requests.

About You

• 5+ years of professional software engineering experience, with hands-on experience building, shipping, and supporting production software using Node.js, React, and TypeScript.
• You are a true full-stack engineer who owns features end to end across frontend and backend.
• You're comfortable deep in the code and confident making architectural decisions and tradeoffs.
• Experience owning:
  • CI/CD pipelines
  • Automated testing
  • Production monitoring and observability
  • Post-production support and iteration
• Experience handling regulated or sensitive data (PII/PIFI) responsibly and intentionally.

Tech Stack and Architecture

• Frontend: Next.js
• Backend Framework: NestJS (Node.js, Typescript)
• Database: PostgreSQL with TypeORM
• Infrastructure: Docker & AWS
• Architecture: Microservices
• Codebase: GitHub & Nx Monorepo
• Observability: Amplitude, Sentry, Splunk, Dynatrace.
