At Coinbase, our mission is to increase economic freedom in the world. It’s a massive, ambitious opportunity that demands the best of us, every day, as we build the emerging onchain platform , and with it, the future global financial system.

To achieve our mission, we’re seeking a very specific candidate. We want someone who is passionate about our mission and who believes in the power of crypto and blockchain technology to update the financial system.

We want someone who is eager to leave their mark on the world, who relishes the pressure and privilege of working with high-calibre colleagues, and who actively seeks feedback to keep levelling up.

We want someone who will run towards, not away from, solving the company’s hardest problems.

Our work culture is intense and isn’t for everyone. But if you want to build the future alongside others who excel in their disciplines and expect the same from you, there’s no better place to be.

While many roles at Coinbase are remote-first, we are not remote-only. In-person participation is required throughout the year. Team and company-wide offsites are held multiple times annually to foster collaboration, connection, and alignment. Attendance is expected and fully supported.

We are looking for a Staff Software Engineer to join the Payment Rails team within Coinbase's Platform organisation.

Payment Rails serves as Coinbase’s gateway between the fiat and crypto economy, connecting our products to a wide range of banking and payment providers, from the largest global institutions to the most innovative, tech-forward processors.

We operate a network of payment integrations and routing that power fiat on- and off-ramps for both individual and institutional customers, moving hundreds of billions of dollars in transaction volume each year.

In this role, you’ll shape the architecture and technical direction of this network, designing and scaling systems that ensure every payment is reliable, efficient, and correct.

**Key Responsibilities:*

• Own the technical strategy, architecture, and roadmap for scaling Payment Rails’ network of payment partner integrations and routing, so Coinbase can enable more customers to participate in the crypto economy across more markets and payment options.

• Build and scale complex distributed systems that process high-volume, high-reliability payment traffic,designing for fault isolation, graceful degradation, strong observability, and clear SLOs for Tier-0/Tier-1 services.

• Drive an AI-first approach to engineering workflows,identify where AI-powered tools can accelerate development, improve code quality, and enhance operational efficiency across the team and broader engineering org.

• Partner cross-functionally with Product, Risk, Compliance, and Operations to translate ambiguous business requirements into well-scoped technical solutions that balance speed, safety, and regulatory requirements.

• Lead high-stakes scaling initiatives and define the technical direction for how Coinbase moves money,anticipating bottlenecks before they occur and driving proactive, systematic improvements.

• Raise the engineering bar across Payment Rails and adjacent orgs by establishing paved roads, design patterns, and best practices that elevate team technical quality through mentorship, design reviews, and process improvements.

• Mentor and train other team members on design techniques and coding standards.

**Requirements:*

• 8+ years of experience in software engineering.

• Experience building payment systems, financial infrastructure, or high-volume transactional systems.

• You’ve designed and built fault-tolerant, highly reliable distributed systems at scale,with a demonstrable track record of architecting systems that handle billions of dollars in transaction volume.

• Platform-builder mindset: you’ve led efforts to turn fragmented services and bespoke integrations into coherent, reusable platforms (e.g., shared frameworks, unified APIs, multi-tenant architectures).

• Strong operational excellence: experience owning production reliability, leading high-severity incident response, and driving systemic improvements from postmortems across multiple teams or domains.

• Collaborative leadership: history of influencing across teams and organisations without direct authority, driving consensus on high-impact technical decisions, and representing your area in org-level forums.

• Demonstrates the ability to responsibly use generative AI tools and copilots (e.g., LibreChat, Gemini, Glean) in daily workflows, continuously learn as tools evolve, and apply human-in-the-loop practices to deliver business-ready outputs and drive measurable improvements in efficiency, cost, and quality.

**Nice to have:*

• Experience with payment processors, banking integrations, or payment gateways (e.g., Stripe, Plaid, SWIFT, ACH, SEPA, card networks).

• Background in crypto or blockchain technologies, including familiarity with stablecoin transfers, on-chain settlements, or cross-chain payment flows.

• Experience working in highly regulated industries where safety, compliance, and user trust are paramount,particularly in fintech or financial services.
