About
We are looking for a
Senior Engineer
to lead the architecture and development of core platform systems. This is a high-ownership role - you'll design and scale the services that process credit card transactions, power real-time rewards at every merchant globally, and integrate with banking cores and payment networks. The systems you build will directly serve major financial institutions and their millions of end customers.
What You'll Do
Lead the architecture, development, and optimization of services across the full stack using PHP and Python, with a focus on scalability, security, and long-term maintainability
Design and implement RESTful APIs and microservices that integrate with banking cores, payment networks, and institutional partner systems
Optimize MySQL performance through query tuning, schema design, and data modeling for high-throughput financial transaction systems
Drive engineering standards for quality, testing practices, and CI/CD workflows across the team
Provide leadership and influence the team's AI tooling strategy - evaluating, adopting, and establishing best practices for AI-assisted development across the engineering organization
Champion security and compliance best practices appropriate for a regulated financial services platform
Bring deep business understanding to technical decisions - the best solutions come from engineers who understand the full picture, from cardholder experience to settlement
Mentor mid-level and junior engineers on system design, full-stack fundamentals, and professional growth
What You'll Bring
6+ years of professional development experience with deep expertise in application architecture and production systems at scale
Strong command of MySQL including query optimization, schema design, and performance tuning
Extensive experience with RESTful API design and microservices architecture
A track record of making sound technical decisions under ambiguity - designing systems, evaluating tradeoffs, and leading through influence rather than authority
Comfort working across the full stack - you're not boxed into backend or frontend, you go where the problem is
Comfort with remote-first, sync and async collaboration and strong written communication skills
Comfort with remote-first, sync and async daily collaboration with fluid times
Ability to balance long-term architectural thinking with pragmatic delivery in a fast-moving environment
Bonus If You Have
Experience in fintech, payments, credit card infrastructure, or regulated financial services
Familiarity with multi-tenant platform architecture or real-time transaction processing
Experience with AI-assisted development tools or integrating LLM APIs into production systems
Background with PCI DSS, SOC 2, or financial compliance requirements
What We Offer
Competitive compensation and equity
Remote-first workplace
Comprehensive health plan and PTO
A team that treats AI as a force multiplier, not a threat
Real ownership - you'll shape the systems and standards that define how we build
Direct influence on the technical direction of a platform serving major financial institutions
