Senior 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've since raised a $35M Series A led by Oak HC/FT, with participation from existing investors New Enterprise Associates (NEA), Coinbase, and Faction VC, and new investors Wilson Sonsini Goodrich & Rosati and OpenFX -bringing our total raised to $43M.

We're looking for experienced software engineers who are excited to build critical financial infrastructure at an early-stage company with significant technical ownership and impact.

As a Senior Software Engineer, you'll help design and build the systems powering the next generation of global payments. You'll work closely with our engineering leadership to solve complex technical challenges, influence architectural decisions, and ship products that serve real customers from day one.

You'll have the opportunity to:

• Design and build scalable, production-grade backend services and distributed systems

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

• Influence system architecture, engineering standards, and technical direction as the platform scales

• Own projects end-to-end, from technical design through deployment and long-term operation

• Collaborate closely with engineering and product to solve complex infrastructure and financial systems challenges

• Mentor teammates, raise the engineering bar, and contribute to a collaborative, high-performing culture

• 5+ years of professional software engineering experience building and operating production systems

• Experience working in high-growth startups or fast-paced environments with significant ownership

• Strong backend engineering fundamentals and experience building reliable, scalable distributed systems

• Proven ability to independently drive complex technical initiatives and make thoughtful architectural decisions

• Experience 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.

• Experience designing APIs, distributed systems, or event-driven architectures

• Experience with modern cloud infrastructure and infrastructure-as-code

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

• Experience helping shape engineering practices, technical strategy, or scaling engineering organizations

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

Rare Opportunity: We're backed by top investors (including NEA and Lightspeed Faction), finding significant traction, and taking on a massive market opportunity in international payments. This is a chance to join a rocketship early and help shape the future of global money movement.

Impact: You'll be building critical infrastructure that makes global payments faster and more accessible for businesses and individuals worldwide.

Strong Team: Join a high-caliber team that combines deep fintech expertise with startup execution experience. Our team has worked on the stuff that matters at companies like Stripe, Coinbase, Uber, and Facebook.

Opportunity to join early: As an early team member at a growing startup, you'll have significant influence over our technical direction and the opportunity to grow with the company.
