Overview

Founding Software Engineer, Crypto — Newport Beach, CA. Company Stage of Funding: Late Seed (Backed by top-tier venture investors). Office Type: On-site, 6 days per week. Salary: $250,000 — $400,000 equity.

Company Description

We are partnered with a stealth-mode financial technology company that has recently raised over $250M at a multibillion-dollar valuation to build the next generation of U.S. banking infrastructure. The company's mission is to rebuild core banking systems from the ground up — creating real-time financial infrastructure that connects directly to the Federal Reserve and supports industries defining the future, including crypto, AI, and defense technology. This is a rare opportunity to join a founding engineering team tackling problems that most engineers will never get the chance to work on — building secure, production-grade blockchain rails and financial systems at national scale.

What You Will Do

• Design, build, and secure wallet infrastructure to support blockchain-based payments and fund transfers.
• Develop internal blockchain rails and crypto transaction systems that integrate directly with broader banking infrastructure.
• Take ownership of backend systems powering real-time crypto and fiat interoperability.
• Define and embed security best practices throughout the crypto software development lifecycle.
• Collaborate closely with cross-functional teams (product, compliance, security) to ensure robust and compliant infrastructure design.
• Contribute to the company's ledger, transaction processing, and on-chain/off-chain reconciliation systems.

Ideal Candidate Background

• 4–6 years of professional software engineering experience.
• Strong understanding of blockchain protocols, wallet infrastructure, and crypto fund transfer mechanisms.
• Experience developing secure systems for managing digital assets or working at crypto exchanges.
• Proficiency in backend languages (Golang preferred; Python or Rust experience a plus).
• Prior experience in a startup or fast-moving technical environment.
• Excellent communication skills and collaborative approach to problem-solving.

Preferred Qualifications

• Experience designing and implementing financial infrastructure or compliance-sensitive systems.
• Familiarity with cryptographic primitives, key management, and blockchain security.
• Contributions to open-source blockchain or fintech projects.
• Strong interest in national-scale financial systems, payments, or stablecoin infrastructure.

Compensation, Benefits & Other Details

• Base Salary: $250,000 — $400,000 depending on experience.
• Equity: Competitive founding-level equity package (high-upside potential).
• Visa Support: H-1B transfer sponsorship available (no new H-1B filings at this time).
• Schedule: On-site 6 days per week in Newport Beach, CA, collaborating directly with the founding team to launch the company's first core banking platform.
• Mission: Be part of a founding team reimagining U.S. financial infrastructure and creating one of the most technologically advanced banking systems in the country.
