• Experience using AI-assisted engineering tools (e.g., Claude Code, Codex, GitHub Copilot) responsibly to improve productivity and engineering quality

What Great Looks Like

A Senior Software Engineer on the Payments team who is thriving at this level demonstrates:

• Reliable delivery of complex work — consistently ships multi-part solutions on time with low defect rates
• Low defects in owned areas — proactively monitors and improves the quality of the systems they own; that means incident-free quarters in code paths that move funds and clean reconciliation against vendor reports
• Measurable mentorship impact — engineers around you write better code because of your reviews and guidance

"Someone we can depend on for the work that matters — especially the work that touches money."

Failure Modes We Screen Against

We actively evaluate candidates for the following anti-patterns during the interview process:

Interview Process

Our 6-round process is designed to evaluate you across all competency areas. AI tools are permitted in technical rounds.

Round 4 is conditional: it runs when the team needs additional behavioral signal after Rounds 2 and 3, and is otherwise skipped. Your recruiter will tell you whether it's scheduled before your loop is finalized.

The Round 2 (Take-Home + PR Discussion) and Round 3 (System Design) exercises are drawn from real problems so the technical evaluation is grounded in the work you'd actually be doing.

What You’ll Receive

• Competitive compensation including base salary, bonus, and equity
• Employer-sponsored 401(k) with match
• Comprehensive medical, dental, and vision coverage
• Flexible time off and hybrid work environment

The anticipated annual salary range for this role is $175,000 - $200,000. Actual compensation and title will be commensurate with experience, qualifications, knowledge, and skills.
