• Build as an exemplary practitioner: get hands-on developing software and set a high quality standard for teams to follow.
• Define the right boundaries, APIs, and integrations between teams and with clients and partners to ensure technical and business success across multiple geographies.
• Solve complex engineering problems endemic to high-availability, low-latency, scalable distributed systems in a regulated banking environment.
• Execute large-scale projects — leading design, planning, and execution across multiple teams to drive technical direction and product outcomes.
• Drive the design and implementation of scalable, secure, and highly available SaaS services and data engineering pipelines that support next-generation core banking capabilities.
• Proactively identify broader problems and opportunities. Anticipate and design the next generation of our systems and products.
• Raise the quality of our engineering teams: identify opportunities and advocate for improvements to how we write software, our approach to testing and quality, and the habits and processes of highly effective teams.
• Mentor and coach individuals and teams across the company. Steward engineering communities, fostering design collaboration and mindshare.
• Articulate how technical architecture and team structure interact, and provide input on the right organizational structure to deliver on our engineering goals.
• Serve as a strategic advisor to leadership, representing technical strategy to business and executive stakeholders and participating in strategic planning.
• Continuously drive improvement, new practices, and operational excellence initiatives across the department.
• Champion improvements in code, design, and operational reviews. Lead initiatives that improve department software quality and operations. Be a stakeholder in engineering norms and standards for code quality, software quality, and operational excellence.

What You’ll Need:

• 10+ years of programming experience; mastery of software development independent of language.
• Advanced expertise in designing, building, and operating large-scale fault-tolerant distributed systems, applications, databases, and workflows.
• Demonstrated experience with continuous delivery principles and techniques: you've built systems with layered test automation that is always safe for automated releases to production, enabling a great, low-cycle-time developer experience.
• Deep expertise in designing and managing cloud-based solutions with a strong focus on resiliency experience with AWS (or other public cloud infrastructure) required.
• A high standard for what "great" looks like, and experience continuously improving legacy systems to reach it.
• Strong judgment, and experience recognizing and driving out critical decisions in a balanced and pragmatic way.
• Excellent verbal and written communication skills with the ability to influence and collaborate effectively across remote, distributed teams.
• Experience working in a regulated industry.
• Experience working on banking backends, particularly cores, ledgers, or payment systems is a plus.
• Bi-lingual Spanish/English required.

What you’ll do:

• Own and drive system design and architecture decisions
• Lead the end-to-end design and implementation of AI solutions
• Write, test, and deploy efficient, scalable code to a production environment that impacts millions of users.
• Generate ideas for process improvement, initiatives, and new technologies.
