About this role

🚀 Founding Engineer, Thera (NYC)

Thera is building the financial OS for modern SMBs. Payroll, payments, treasury, spend, and accounting in one ecosystem that actually works end-to-end.

We're looking for our first NYC-based Founding Engineer to help scale the systems powering global payroll and money movement, work alongside our existing engineering team in India, and seed our in-person engineering culture from day one.

This is a true founding role. You'll be in the code, owning large pieces of the product, and working directly with the CEO.

📍 NYC, 5 days/week

Why we started Thera

Our founders saw firsthand how broken SMB payroll and finance had become. The average SMB stitches together 5+ tools just to pay people, move money, and close their books. We started Thera to collapse that fragmented stack into a single source of truth.

Backed by YC, 10X Founders, Zillionize, and Amino Capital.

What you'll own

  • Core systems powering global payroll and money movement
  • Large pieces of the product, end-to-end
  • Helping lead our existing engineering team of 5+ in India
  • Building our in-person engineering presence in NYC from scratch
  • Direct partnership with the CEO and product team

Your first 90 days

30 days

  • Ship a meaningful improvement or net-new feature on the spend product
  • Get deep with the product team and the India engineering team

60 days

  • Map out future builds across the roadmap
  • Start leading product meetings

90 days

  • Ship autonomously across at least one product surface
  • Help build out our NYC in-person engineering culture
  • Influence how we hire the next wave of engineers

About you

-

3 to 7+ years building and shipping production systems

- You thrive in ambiguity, move extremely fast, and care deeply about craft

  • Comfortable owning features end-to-end from zero to one
  • Bias toward action, simple solutions, and high standards
  • Comfortable working with a distributed team across time zones

Stack today: TypeScript + Java/Kotlin

Not a fit if

  • You want a pure management role
  • You avoid ambiguity or messy real-world systems
  • You're not willing to be in-person in NYC

Why Thera

  • Huge ownership and meaningful equity
  • Direct impact on product and culture

-

A chance to build one of the most important fintech platforms of the next decade
