Design and build payout and money-movement systems on top of Payment Service Providers, including onboarding, KYC, country and payout-method support, webhook reconciliation, retries, and rate-limit handling, with zero-downtime rollout and full auditability for every state change. - Build out a robust and flexible payment and incentives platform that powers how fellows are compensated, rewarded, and retained across every project we run. - Build the Trust & Safety stack: KYC and re-verification flows, sanctions and fraud screening, ban and suspicious-account state transitions, and time-tracking audits over activity, time confirmations, and pay rates. - Own operator tooling, including the Pay admin dashboard, ledger, and operations that let our ops team run pay weeks safely. - Lead end-to-end on schema design, migrations, and backfills across Postgres and design rollouts that are safe to deploy. - Set the bar for engineering practices on the squad through system design reviews, incident response, runbooks, and observability, and mentor other engineers through code review and architectural guidance. ## What We’re Looking For
5+ years of professional software engineering experience, with meaningful time spent owning production systems where correctness and uptime matter (payments, fintech, identity, fraud, infrastructure, or similar high-stakes domains). - Strong system design fundamentals for highly reliable, zero-downtime, auditable, and resilient systems: expand-contract migrations, idempotency, retries and backoff, dual-writes and backfills, append-only audit logs, and reconciliation jobs. - Deep proficiency with relational databases (PostgreSQL), data modeling, and schema evolution under load. You can defend why a given state is or isn't reachable. - Strong backend skills in Ruby on Rails and/or TypeScript/Node, and willingness to work fluently across both. - Comfort in React for operator and fellow-facing UI. - Experience designing and operating asynchronous workflows (Temporal, Sidekiq, or similar) and integrating with third-party APIs that fail in interesting ways (Stripe, Deel, Hubstaff, or equivalents). - Track record of leading technical projects end-to-end in ambiguous environments, with a bias toward shipping behind feature flags and verifying in production. - Excellent communication and stakeholder management. You can partner with Ops, Finance, Legal, and Compliance and translate their requirements into system invariants. - Track record of mentoring engineers and raising the engineering bar on a team. ## Nice to Have
Prior experience building production payments, payout, or money-movement systems
Background in Trust & Safety, fraud, KYC/AML, sanctions screening, or identity verification at scale. - Experience with event sourcing, change-data-capture, or audit-log architectures where every state change is reconstructable. - Experience operating comparable workflow orchestrators for long-running, idempotent business processes. - Experience with regulated or compliance-driven workstreams (1099-NEC issuance, OFAC, GDPR/data deletion, SOC 2 controls). ##
