Senior Full-Stack Engineer (Node.js, React)
We are looking for a Senior Full-Stack Engineer (Node.js, React) with 5+ years of experience, an upper-intermediate+ level of English and fluency in Ukrainian to join our team.
About Company
Wise Engineering is a company where every team member contributes to success — founded in 2006. We have a depth of experience in developing and successfully launching customer startups. Since 2016, we have started to work on our products.
WE are proud of the atmosphere of personal growth and mutual support we have built. Work for us is more than just “working hours”, we believe that enjoying the process is as important as the good results. “Do what you love and love what you do” is about us.
About the Project
We are building a modern operating system for risk, compliance, and vendor management in the U.S. mortgage industry is a $12T+ market still relying on fragmented, outdated tools.
This is not an idea-stage startup.
- Paying customers
- 3,000+ active users
Proven product-market fit
Our goal is to become the default compliance platform for mortgage companies nationwide, with 10,000+ companies using the product daily by the end of 2026.
You will join a small, senior, high-ownership team:
- 2 Founders (product, strategy, customer-facing)
1 Founding Engineer (full-stack, infrastructure)
We operate with high trust, clear communication, and full ownership. Everyone on the team directly shapes the product.
Tech Stack:
Frontend: Next.js, React (custom hooks, components), Redux
Backend: Express, MongoDB + Mongoose, CRON jobs
Infrastructure: Railway, MongoDB Atlas, AWS S3, Sentry
Language: JavaScript (migrating to TypeScript in 2026—this is a major priority)
Tooling: Slack, Linear, Loom, AI dev tools (Cursor, Roo Code)
If you’re thinking “I’d change half of this,” good. Tell us why.
Nice to have:
- Experience with TypeScript (or strong interest in migrating a codebase)
- Familiarity with AI APIs (OpenAI, Anthropic, etc.) and integration patterns
- Background in fintech, compliance, or regulated industries
- Experience with automated testing, QA processes, and error monitoring tools (Sentry, etc.)
- Exposure to document processing, OCR, or data automation workflows
What You’ll Be Doing
You’ll own features end-to-end from database schema to polished UI. This isn’t a role where you throw code over the wall. You design, build, ship, and maintain.
Immediate priorities (3 — 6 months):
- Build features to reach parity with legacy competitors
- Improve UI/UX across the platform (we’re good, want to be great)
- Develop AI-powered document review/OCR solution to automate compliance tasks
- Build AI agents that pull data from the web to autocomplete onboarding workflows
Identify and implement practical AI use cases that solve real customer problems
Medium-term (12 months):
- Launch our Vendor Management Platform
- Drive the TypeScript migration across the codebase
- Implement QA processes and automated testing (with AI assistance)
Triage and resolve production issues surfaced in Sentry
Long-term (2+ years):
- Launch Products #3 & #4 to complete the risk and compliance ecosystem
- Help us build the single platform every mortgage bank will rely on—nothing like this exists today
How We Work
Async-first. High-trust. High-agency.
- No daily standups. No micromanagement.
- We review priorities weekly and make sure everyone’s working on the highest-impact task.
- Deadlines and blockers are communicated in Slack. Updates via Loom.
- We value written communication, it forces clarity and works across timezones.
- We’re a curious, opinionated group who debate ideas and seek the best solution, not the loudest voice.
We care deeply about product design and thoughtfulness. The feedback we hear most on demos is: “Wow, it looks so great and feels so intuitive.” We’re proud of that but we know we can do even better.
