Web3 Ruby Jobs in United States

Software Engineer

Latitude is an early-stage payments fintech building modern infrastructure for global money movement. We help businesses move value instantly, securely, and with full compliance - leveraging blockchain rails while delivering a seamless, enterprise-grade experience.

Our team has built and scaled payments and financial infrastructure at Uber, Coinbase, Stripe, Amazon, and Facebook - bringing deep experience across fintech, marketplaces, and global-scale systems. In January 2025, we raised an $8M seed round led by NEA, with participation from Lightspeed Faction, Coinbase Ventures, Paxos, Bitso, Solana Ventures, and others.

We're looking for talented software engineers who are excited to build critical financial infrastructure, ship high-quality code, and take meaningful ownership at an early-stage company.

The Role

As a Software Engineer, you'll build and ship the products and systems powering the next generation of global payments. You'll work closely with experienced engineers and product partners to solve challenging technical problems, write high-quality production code, and deliver features that serve real customers.

You'll have the opportunity to:

• Build, test, and ship reliable production-grade backend services and APIs

• Develop core platform components across payment orchestration, ledgering, workflow engines, partner integrations, and public APIs

• Write clean, maintainable code and contribute to code reviews, testing, debugging, and technical documentation

• Own features and projects from implementation through deployment and ongoing operation

• Troubleshoot production issues and continuously improve the reliability and performance of our systems

• Collaborate closely with engineering and product to translate business and customer needs into technical solutions

• Contribute to engineering standards and best practices as the team and platform grow

What We're Looking For

Required

• 3+ years of professional software engineering experience building and shipping production software

• Strong software engineering fundamentals and hands-on coding skills

• Experience building backend services, APIs, or other production applications

• Ability to write clean, reliable, well-tested, and maintainable code

• Experience working in fast-paced environments where engineers take ownership and ship quickly

• Ability to independently execute on well-scoped technical projects while collaborating effectively with more senior engineers on complex problems

• Experience in or interest in one or more of the following areas:

  • Infrastructure / DevOps

  • Payments or financial systems

  • Blockchain / crypto infrastructure

• Product-minded approach with a willingness to work across the stack when needed

• Strong communication and collaboration skills

• Authorization to work in the United States

Our backend is primarily written in Ruby, with TypeScript powering our frontend. Our infrastructure runs on AWS using Terraform and Kubernetes. Experience with these technologies is a plus, but we value strong engineering fundamentals and the ability to learn quickly over expertise in any particular language or framework. We’re looking for engineers with strong character and empathy - we're building a collaborative, kind, high-achieving culture.

Preferred

• Experience working at a startup or in another high-growth engineering environment

• Experience building APIs, backend services, or event-driven applications

• Familiarity with cloud infrastructure and modern development practices

• Background in fintech, payments, banking, digital assets, or other regulated industries

• Experience working with Ruby, TypeScript, AWS, Terraform, or Kubernetes

• Familiarity with AI-assisted development workflows and modern engineering tooling
