• Execute the full software development lifecycle across both backend services and frontend interfaces
• Design and build well-tested, well-documented features that span APIs, data models, and UI
• Produce technical specifications and assess operational feasibility for new payments features
• Integrate components into cohesive, production-ready systems with appropriate observability
• Contribute to verification plans, quality assurance procedures, and deployment guardrails
• Maintain and improve existing functionality, including documentation
• Participate in deployment planning, on-call rotations, and incident response as part of running a payments platform
• Use AI-assisted development tools effectively to improve velocity without compromising quality
• Stay current with platform updates, security practices, and PCI compliance requirements

Requirements:

• 4+ years of professional software engineering experience, with a Computer Science/Engineering degree or equivalent
• Strong Node.js experience and demonstrated ability to ship production backend services
• Experience building React-based frontends that consume RESTful APIs
• Experience designing and building RESTful APIs and microservices
• Working knowledge of relational databases (PostgreSQL preferred) and clear understanding of separation of concerns in service design
• Hands-on experience with AWS or a comparable cloud platform
• Experience with CI/CD pipelines (Bitbucket Pipelines, GitHub Actions, or similar)
• Proficiency with Git, agile delivery (Scrum preferred), and testing frameworks like Jest
• Fluency with AI-assisted development tools (Claude Code, Cursor, Copilot, etc.) and an articulate point of view on where they help and where they don't
• Comfortable working on a 100% remote team and able to operate independently within an agile group
• Experience building or operating payments systems — payment orchestration, tokenization, acquirer integrations (Worldpay, Stripe, Adyen, Finix, Basis Theory), or PCI-compliant environments
• Familiarity with event-driven architectures (SQS, EventBridge, Kafka)
• Exposure to observability tooling (SigNoz, Grafana, Datadog, etc.)
• Infrastructure-as-code experience (Terraform)
