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."

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

Failure Mode

What It Looks Like

Strong coder weak owner

Ships code but doesn't manage to the task — owns the merge not the outcome; hands off and moves on without monitoring or fixing post-release issues

Solo expert

Hoards knowledge instead of sharing — becomes a single point of failure and blocks team growth

Overconfident designer

Proposes solutions without considering trade-offs — jumps to conclusions resists alternative approaches

Rubber-stamper

Produces AI-generated output without verifying it against the codebase tests or business context

Our 5-round process is designed to evaluate you across all competency areas. AI tools are permitted in technical rounds.

Round

Format

What We Evaluate

1 — Hiring Manager Screen

60 min conversational

Career trajectory mentorship philosophy technical influence examples communication style

2 — Take-Home + PR Discussion

72h take-home + 60 min live

Navigating unfamiliar code ownership and decomposition discipline visible in your PR root-cause judgment AI tool usage

3 — System Design + Artifact Critique

60 min Miro board

Requirements gathering schema/API design trade-off articulation calibrated code-review judgment on a teammate's PR

4 — Team Interview (conditional)

30 min behavioral

Collaboration patterns mentorship behavior negotiation behavior with cross-functional partners

5 — Culture Add

30 min People Team

Organizational values alignment

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.

• 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
