Job summary

PayJunction is seeking a Software Architect to design and build enterprise features and payment integrations our partners rely on to move billions of dollars a year, taking open-ended problems from a blank page to production while still writing Java yourself.

Location options include remote, with a Flex First approach allowing work from home or Santa Barbara office. Ideal candidates have 10+ years in software engineering and 5+ years architecture leadership, with strong Java and AWS expertise.

Qualifications

• 10+ years of professional software engineering with ownership of production systems.

Responsibilities

• Lead open-ended initiatives from blank page to production with Product and Engineering leadership, breaking the problem down, directing other engineers, and making the calls that keep the team moving.
• Personally design the highest-risk systems end to end, writing design docs clear enough to build from, with requirements, trade-offs, and failure modes stated up front.
• Stay hands-on: write production Java every sprint, review pull requests promptly, and hold work to a test strategy built for high-risk payment paths.
• Mentor senior engineers through design reviews, code reviews, and pairing, growing the team's design capability so not every decision runs through you.
• Architect enterprise capabilities such as SSO, role-based access, audit trails, and multi-merchant hierarchy, plus versioned APIs partners can build on without breaking changes.
• Keep the core platform processor-agnostic and our processor integrations performing optimally, from message mapping through reversals and settlement reconciliation.
• Design for reliability and PCI from the start: define SLOs and monitoring, remove single points of failure, lead root-cause analysis, and shrink PCI scope by design.
• Raise the team's delivery velocity with AI-assisted development, setting review and security guardrails for AI-generated code.
