• Deliver Features End-to-End: Ship user-facing features in our core domains with a focus on measurable outcomes. • Cross-stack Development: Work hands-on with our mobile stack (Flutter, Dart) and extend into backend and web systems where appropriate. • Build with Care: Develop software following modern practices: API-first design, code reviews, automated testing, and utilizing MR environments for exploratory testing before a merge. • Validate What You Build: Instrument your features, observe how users actually behave, and use what you learn to refine, double down, or drop what doesn't work. • AI-Enabled Growth: Transition toward an AI-supported workflow, shifting focus from 'writing code to spec' to holistic, end-to-end solution ownership. • Own Your Features: Own the features you deliver — from technical decisions and cross-team alignment in our guilds to rollout and iteration.

• Own mission-critical systems: Design, build, and operate reliable backend systems that support money movement, benefit spending, account verification, transaction processing, reconciliation, and related workflows. • Lead ambiguous projects end-to-end: Take large, complex problems from discovery and technical design through implementation, release, monitoring, and iteration. • Drive product and business impact: Partner with product, operations, finance, and business teams to understand user needs, business goals, and operational constraints. • Shape technical direction: Make architectural decisions that balance speed, reliability, security, compliance, maintainability, and user experience. • Build reliable financial infrastructure: Develop systems with strong guarantees around correctness, idempotency, auditability, observability, and failure recovery. • Contribute across the stack: While the role is backend-focused, contribute to frontend experiences when needed to deliver complete product outcomes. • Raise the engineering bar: Write clean, maintainable code; participate in thoughtful code reviews; mentor other engineers; and champion engineering best practices. • Operate with urgency and ownership: Move quickly while maintaining high standards for quality, security, and reliability.
