About the Role

As a Staff Software Engineer in Banking, you will help shape the technical direction of one of Brex’s most strategic and complex product areas. The Banking org owns the Brex Business Account product, AP offerings like Bill Pay and Vendors, and the underlying money movement platform and partner integrations.

In this role, you’ll work across customer-facing product surfaces and core financial infrastructure, driving architecture, reliability, and execution. You will move between long-horizon technical strategy and hands-on execution, collaborating closely with engineering, product, design, data, operations, risk, compliance, and external partners.

Responsibilities

• Lead technical strategy for critical Banking initiatives, balancing long-term architecture with near-term delivery needs across multiple teams.
• Drive the design and evolution of reliable, scalable systems for money movement, bank account experiences, payment orchestration, and related financial infrastructure.
• Partner cross-functionally with product, design, operations, compliance, risk, and accounting to turn complex business and regulatory requirements into durable technical solutions.
• Identify and resolve systemic reliability, quality, and operability issues, improving observability, incident prevention, and engineering standards over time.
• Provide technical leadership across teams by driving architecture reviews, aligning stakeholders, and helping teams make strong tradeoffs in ambiguous spaces.
• Mentor senior engineers and emerging technical leaders, helping raise the bar on system design, execution, and technical ownership within the Banking org.
• Contribute directly when needed — whether through design, debugging, rollout strategy, or implementation — especially for high-stakes initiatives and critical path decisions.

Requirements

• 8+ years of software engineering experience, including experience operating as a senior technical leader on complex, multi-team initiatives.
• Demonstrated track record of leading architecture and delivery for large-scale distributed systems in a product or platform engineering environment.
• Strong systems thinking and the ability to simplify complex technical and organizational problems into clear, actionable plans.
• Experience improving reliability, operational excellence, and engineering quality in production systems with meaningful customer or business impact.
• Ability to work effectively across engineering, product, design, operations, compliance, risk, and other cross-functional partners.
• Strong written and verbal communication skills, with the ability to influence senior stakeholders and align teams without direct authority.
• Hands-on technical depth and sound engineering judgment, including the ability to dive into implementation details when needed.
• Experience mentoring senior engineers and helping scale technical leadership across an organization.

Bonus Points

• Experience in fintech, banking, payments, ledgering, or money movement systems.
• Experience building systems in highly regulated environments.
• Experience leading large migrations, platform consolidations, or service modernization efforts.
• Experience working with external financial or infrastructure partners and integrating third-party systems into critical product flows.
• Experience defining technical strategy for org-level investments that span product, platform, and operational workflows.

Work Arrangement

This role is hybrid based out of San Francisco, CA, requiring 3 days per week in the office (Monday, Wednesday, Thursday), with up to four weeks per year of fully remote work.
