## Job description

Software Engineer, Full Stack Chicago | Engineering | In office | Full-time Compensation Range: $100k-$140k

## About InstaSwitch

InstaSwitch is the fastest way for banks and fintech platforms to activate new accounts, driving deposits and primary relationships. Businesses hesitate to switch accounts due to time and complexity, leading to lost primacy. InstaSwitch automates switching, seamlessly moving income sources, payroll, and spend with minimal effort.

## About This Role

Account switching is a genuinely hard problem - moving payroll, recurring payments, and spending patterns from one financial institution to another requires integrating with a fragmented ecosystem of banks, financial aggregators, and merchant sites, often with inconsistent APIs and incomplete data. We're building the infrastructure that makes this seamless at scale, and we're doing it with a small team that moves fast and owns everything it builds. We need a strong full-stack engineer who thrives on variety. You'll work across a Rails backend, a TypeScript/Lit frontend, Python microservices, and AWS infrastructure - sometimes in the same day. The work ranges from building partner-facing APIs and banking integrations to shipping frontend components to standing up new services from scratch. If you're energized by a high-variety workload where your decisions run in production for years, this is the right role.

## What You’ll Do

- Build and scale our backend infrastructure using Rails 7+
- Contribute to our Lit/TypeScript frontend and client SDK
- Build seamless API integrations with banking platforms and financial services
- Rapidly prototype, test, ship, and iterate on new features
- Maintain and scale secure AWS infrastructure
- Collaborate closely with a small, senior team on architecture and technical direction

## What We’re Looking For

- 4+ years of software engineering experience
- Strong Ruby on Rails experience
- Proficient in TypeScript
- Fintech experience
- Comfortable working across the stack and in AWS
- Comfortable building and iterating without a lot of process scaffolding
- Startup or small team experience
- Self-directed and effective in ambiguous problem spaces — you figure things out rather than waiting for clear requirements

## Nice to Have

- Experience with Lit or web components
- React or equivalent frontend framework experience
- Web automation experience
- Experience with financial data provider integrations (Plaid, Teller, etc.)
- Python proficiency

## Why InstaSwitch

Small team, real ownership, hard problems. You won't be maintaining someone else's system — you'll be building ours. If you want your work to matter and your opinions to be heard, this is the right stage to join.

## Benefits

- Competitive salary ($100k-$140k) w. equity options
- Health, dental, and vision benefits
- High-impact role with direct influence on product direction

How to Apply If this sounds like your kind of opportunity, we’d love to hear from you. Send your resume to contact@instaswitch.co. We're happy to see side projects, open source contributions, or links to things you've built, whatever you think best represents you.

## About InstaSwitch

## Company Overview
- **One-liner**: InstaSwitch automates the switching of income, payroll, spend, vendors, and clients for business banking accounts, turning opened accounts into funded, primary relationships.
- **Entity Type**: Private (Seed stage, raised $4.7M in May 2026)
- **Headquarters**: New York, New York, United States (with an office in Chicago, Illinois)
- **Founded**: 2024
- **Founders**: Daniel West (Founder & CEO)

## Core Business
- **Primary industry**: Financial Services (B2B fintech infrastructure)
- **Target customers**: Fintechs, banks, and credit unions (business banking providers)
- **Mission**: Help financial institutions turn opened accounts into primary relationships by making switching seamless and automated.

## Products & Services
- **Hosted Platform**: A white-labeled, branded link that any team member can send to customers. Customers complete the switch inside the bank’s flow.
- **Embedded SDK**: Deploys inside a bank’s product in under two weeks, fully white-labeled with the bank’s colors and copy. InstaSwitch is invisible to the end user.
- **API (upcoming)**: Full control for banks to build their own experience, with InstaSwitch as the execution layer for automations and guided flows.

All services automate the process of moving income, payroll, spend, vendors, and clients from the old bank to the new account, with direct API connections for common tools and guided flows for others.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding of $4.7M (Seed round, May 2026)
- **Notable Investors/Partners**: Four unnamed institutional investors; announced a partnership with **Swaystack** to help banks and credit unions turn newly opened business accounts into primary relationships. Cleared InfoSec and risk review at a **$40B financial institution** in under six months.
- **Growth Signals**: 
  - Headcount grew **133.3% year-over-year** (to 5 total employees as of mid-2026).
  - **80%+ completion rate** among users who begin the switching flow.
  - Customers who complete the switch within 7 days deliver **95% higher lifetime value**.
  - Live in production at business banking platforms and banks across the U.S.

## Competitive Advantages
- **Full automation of the switching process**: Unlike manual account-opening tools, InstaSwitch handles the entire post-opening workflow (income, payroll, spend, vendors, clients) in one 15-minute session.
- **High completion rate**: 80%+ of users who start the flow finish it, compared to industry-wide failure rates where most new accounts never fund.
- **Proven institutional trust**: Passed the security and risk review of a $40B financial institution in under six months, a strong signal for enterprise adoption.

## Strategic Focus
- **Scale and deepen existing integrations**: Add more financial institutions and increase the breadth of tools supported within each institution.
- **Build the team**: Hiring across engineering and product to accelerate platform expansion, with a focus on full-stack engineers who want ownership and direct impact.
- **Prepare API launch**: The API offering (Q3/Q4 2026) will give banks full control over the switching experience.

## Why Work Here
- **Culture**: Early-stage startup where engineers have full ownership from idea to shipped product. “No defined lanes” – you push things forward independently.
- **Work environment**: Hybrid – 3–4 days per week in the Chicago office (Fridays are typically remote). New York HQ also has presence.
- **Perks**: Unlimited PTO, dental insurance, AWS services. Small team (5 people) means outsized impact on product and company direction.
- **Engineering excellence**: The team emphasizes moving fast, communicating with precision, and building real infrastructure used by banks.
