## Job description

## OVERVIEW

This position can be based out of San Francisco, New York, or remote (we accept candidates from the following states: AZ, CA, CO, CT, FL, GA, HI, IL, MA, MI, MN, MT, NC, NJ, NV, NY, OH, OK, OR, PA, TN, TX, UT, WA, WI).

We're looking for Full-Stack Software Engineers who want to help businesses of any size move money worldwide. You will contribute to APIs, banking infrastructure and financial workflows that ensure our customers can adopt and scale with Modern Treasury.

Whereas most SaaS companies move data, we move money. Our systems must scale to high volumes, with high accuracy and high reliability. Engineers at Modern Treasury design thoughtful design APIs, implement resilient processes, and choose infrastructure that prioritizes fault tolerance and long-term maintainability over chasing latest trends.

Our application is powered by Ruby on Rails, Postgres, Redis and ParadeDB. As of today, we are on the latest version of each technology. Github and typical CI/CD automation is used for deployments to AWS. While engineers have specialties, engineers can easily contribute to all layers and components of the application without friction.

## ABOUT MODERN TREASURY

Modern Treasury provides trusted infrastructure for money movement. The company helps teams launch and scale payment experiences in days, not months. With best-in-class developer tools and a single API for fiat and stablecoins—plus built-in compliance, ledgering, and reporting— Modern Treasury enables businesses to move money instantly, reliably, and at scale.

$750T+ moves across the bank rails each year. However, despite this incredible volume, the technology powering these rails has not kept pace with digital transformation in other industries. With the significance and scale of this opportunity in mind, Dimitri, Matt, and Sam founded Modern Treasury in 2018 to support the world's largest industries and money movers. Today, the company has grown to serve companies in the economy's most important sectors, from real-estate, healthcare, and insurance, to education and financial services.

## WHAT YOU’LL DO

- Build end-to-end features individually or in small teams
- Iterate and ship code frequently
- Participate in maintenance and ownership of a core component
- Learn the payments space and shape projects before development
- Be mentored and eventually become a mentor

## MINIMUM REQUIREMENTS

- 2+ years of professional software engineering experience
- Interested in full-stack development, including backend jobs, DBs and frontend UX
- A history of collaborating with a team to ship a major feature

## PREFERRED REQUIREMENTS

- Experience with Ruby on Rails, React & Postgres
- Experience with financial software for banks, credit card processing or cryptocurrencies.
- Ability to thrive in autonomous, engineer driven environment

## About Modern Treasury

## Company Overview
- **One-liner**: Modern Treasury provides a single API and unified ledger for fiat and stablecoin payment infrastructure, enabling companies to launch and scale money movement products rapidly.
- **Entity Type**: Private (Series C; total funding $183M)
- **Headquarters**: San Francisco, California, USA (with an additional office in New York, NY and presence in Spain)
- **Founded**: 2018
- **Founders**: Matt Marcus (CEO) and Dimitri Dadiomov (President & Co-Founder)

## Core Business
- **Primary industry**: Financial technology (payments infrastructure, banking-as-a-service)
- **Target customers**: B2B – enterprises, financial institutions, fintechs, marketplaces, payroll platforms, and any business that moves money at scale.
- **Mission or purpose statement**: “To be the most trusted infrastructure for global money movement” and to help money move “at the speed of the internet” by bridging fiat and stablecoin rails.

## Products & Services
- **Payment Operations API**: A single RESTful API that abstracts ACH, FedNow, wire, and stablecoin rails, enabling companies to send and receive money, manage accounts, and reconcile in real time.
- **Programmable Accounts**: Virtual account creation and management with a real-time ledger for tracking balances, deposits, and transfers.
- **Stablecoin Orchestration**: On‑ and off‑ramp stablecoin transactions (e.g., USDC) alongside traditional fiat rails, with built‑in compliance.
- **Wallet Infrastructure**: Digital wallet support for holding and moving both fiat and stablecoins under one ledger.
- **B2B Invoicing & Cross‑Border Payments**: Unified payments for invoicing, global USD accounts, and multi‑currency collections/payouts.
- **Embedded Solutions for Marketplaces, Payroll, Lending, Card Issuing & Rewards**: Pre‑built modules that let platforms embed payment capabilities without rebuilding back‑end infrastructure.

## Market Standing
- **Valuation**: Not publicly disclosed.
- **Key Metric**: Total funding of **$183M** (across Pre‑Seed, Seed, Series A, and two Series C rounds). The company reports having processed **over $600 billion in payments** (website) – though LinkedIn cites “over $400 billion” (likely an earlier figure).
- **Notable Investors/Partners**: Benchmark (led Series A), Altimeter Capital (led Series C), Salesforce Ventures, and several other institutional investors. Acqui‑hire of Beam.
- **Growth Signals**: 
  - Launched stablecoin orchestration and global USD accounts, indicating expansion into crypto‑native and cross‑border use cases.
  - Active job postings: **17 open roles** as of mid‑2026, with monthly postings up 21.4% and yearly postings up 325% – suggesting renewed headcount growth after a significant reduction (headcount dropped 39.6% YoY to ~98 employees).
  - Multiple industry‑focused solutions (payroll, lending, card issuing) signal product‑led expansion.

## Competitive Advantages
- **Dual‑rail platform**: Unlike competitors that focus solely on fiat (e.g., Plaid, Finicity) or solely on crypto (e.g., Circle), Modern Treasury unifies fiat and stablecoin rails in a single API with a real‑time ledger.
- **Proven scale**: Over $600B in payments processed, used by “hundreds of organizations” including leading enterprises and financial institutions.
- **Compliance built‑in**: Automated compliance workflows for both fiat and stablecoin transactions reduce regulatory burden for clients.
- **Developer experience**: “One API, go live in days, not months” with best‑in‑class developer tools and documentation.
- **Uptime guarantee**: 99.99% uptime for core platform.

## Strategic Focus
- **Stablecoin leadership**: Betting heavily on stablecoin regulatory clarity to become the default infrastructure for companies that want to offer both fiat and crypto payments.
- **Global expansion**: Enabling cross‑border payments and USD accounts for international businesses, reducing reliance on correspondent banking.
- **Platform depth**: Adding vertical‑specific modules (payroll, lending, card issuing) to move up‑stack and increase wallet share with existing customers.
- **Go‑to‑market efficiency**: After a period of contraction (headcount down ~40% YoY), the company is re‑hiring selectively, focusing on engineering, security, and customer success roles.

## Why Work Here
- **Culture**: Described as “principled operators solving some of the hardest problems in money movement.” The team values “trust, curiosity, and constructive feedback” and moves fast while thinking deeply.
- **Remote/Hybrid/Office**: Offices in San Francisco (77 Geary St.) and New York (184 Fifth Ave.). The presence of at least one employee in Spain suggests some remote flexibility, but the majority of roles appear to be US‑based with an expectation of in‑office presence in SF or NYC.
- **Notable perks**:
  - Unlimited PTO
  - Comprehensive healthcare (HMO, PPO, dental, vision)
  - 16 weeks paid parental leave
  - Family planning resources (Carrot)
  - Home office stipend & books/learning stipend
  - 401(k) through Fidelity
  - Charitable donation matching
- **Engineering culture**: Strong developer tooling focus; the engineering team (43 people) works on ledgering, APIs, security, and stablecoin infrastructure. Recent job openings include multiple Software Engineer (Security) and Infrastructure roles, indicating investment in reliability and trust.
- **Rating**: 3.5/5 on employer rating (42 reviews) – with highest marks for Work‑Life Balance (4.2) and Culture (4.0), lowest for Career Development (3.3). The recent VP of People departure (Feb 2026) may signal organizational change.
